SpaceX Falcon Heavy Successfully Launches GOES-U Satellite

On June 25, a SpaceX Falcon Heavy rocket successfully lifted off from Kennedy Space Center’s Launch Complex 39A at 5:26 p.m. Eastern, carrying the GOES-U weather satellite, the final spacecraft in a series of geostationary weather satellites. This launch featured several notable firsts, overcoming previous weather forecasts that had predicted only a 30% chance of favorable conditions.

The GOES-U satellite, successfully deployed from the Falcon Heavy’s second stage four and a half hours after liftoff, after the stage completed a sequence of three burns to place the satellite into a geostationary transfer orbit. Built by Lockheed Martin for the National Oceanic and Atmospheric Administration (NOAA), GOES-U will be renamed GOES-19 upon reaching geostationary orbit. After on-orbit commissioning, it will be positioned at 75 degrees east in geostationary orbit, taking over from GOES-16 as the operational GOES-East satellite.

GOES-U carries a suite of earth and space science instruments similar to its predecessors but includes the new Compact Coronagraph (CCOR) instrument for solar observation. CCOR will monitor the solar corona for flares and coronal mass ejections, a crucial function for understanding space weather. This role was previously filled by the nearly 30-year-old Solar and Heliospheric Observatory spacecraft.

The GOES-R series, which began with a launch in 2016, has significantly improved weather forecasting. Ken Graham, director of the National Weather Service, stated at a pre-launch briefing, “The GOES-R series of satellites, it’s been a gamechanger for us.” The satellites have enabled new and improved forecasts, warnings, and services that help save lives and protect property.

Among the enhancements in the GOES-R series is a lightning mapper. Pam Sullivan, director of the GOES-R program at NOAA, highlighted its impact, saying it allows meteorologists to better understand storm severity and issue more accurate warnings. “The main thing I hear from forecasters is that they have more confidence in a forecast,” she noted.

NOAA is already planning the next generation of geostationary weather satellites, called GeoXO, set to begin launching in 2032. Contracts have been awarded to Lockheed Martin for satellite construction and BAE Systems for sounder and ocean color instruments. Steve Volz, assistant administrator of NOAA’s Satellite and Information Service, described GOES-U as “the bridge that connects today’s geostationary satellite technology with the technology of tomorrow.”

The launch was marked by the synchronized landings of the two Falcon Heavy side boosters at Landing Zones 1 and 2 at Cape Canaveral Space Force Station. This mission was also the first time NOAA launched a GOES weather satellite on a SpaceX rocket. The three previous GOES-R satellites launched on Atlas 5 rockets from United Launch Alliance (ULA), but SpaceX was awarded the $152.5 million contract for the GOES-U launch in September 2021 after ULA withdrew due to a lack of available Atlas rockets.

The Falcon Heavy’s additional performance is a key advantage. Julianna Scheiman, director of NASA science missions at SpaceX, explained that the rocket’s capability allows for a significant delta V reduction, meaning the spacecraft requires less energy to reach its final orbit. This efficiency translates into fuel savings and extended operational life for GOES-U, which has a design specification of 15 years. “With the added capability Falcon Heavy is giving us, we expect to be at 20-plus years of fuel life,” said NOAA’s Sullivan.

The GOES-U launch marked the 10th overall for the Falcon Heavy and the second contracted by NASA, following the Psyche asteroid mission in October 2023. Another Falcon Heavy is set to launch NASA’s Europa Clipper mission this October, continuing SpaceX’s role in advancing space exploration and weather monitoring capabilities.

Satellite Shorts From All Over

+ The Ariane 6 rocket recently completed its final ‘wet dress rehearsal’ at Europe’s Spaceport in French Guiana, marking a crucial milestone before its maiden launch. This rehearsal involved loading 180 tons of supercooled propellant into the rocket, cooling its components to cryogenic temperatures, and rolling back the mobile gantry. ESA’s Guy Pilchen highlighted that this rehearsal allowed teams to refine launch operations using the actual flight hardware and software. Following fueling, the rocket underwent final preparations for its upcoming launch, expected to confirm its date after data analysis. With payloads ranging from Earth observation to scientific experiments, Ariane 6 aims to secure Europe’s independent access to space and advance space exploration. (ANS thanks the European Space Agency for the above information)

+ China’s Chang’e 6 probe has returned to Earth on June 25, 2024, with the first-ever samples from the far side of the moon, landing in Inner Mongolia on Tuesday. The successful mission marks a global milestone, with the samples expected to include 2.5 million-year-old volcanic rock that could shed light on the geological differences between the moon’s near and far sides. The probe landed in the moon’s South Pole-Aitken Basin, providing samples from various geological layers. This mission is part of China’s growing space rivalry with the U.S. and other nations, aiming to establish China as a technological power. The journey began on May 3 and lasted 53 days, involving drilling into the core and collecting surface rocks. China plans to share the samples with international scientists, hoping to answer fundamental questions about lunar geology and the solar system’s early days. (ANS thanks Huizhong Wu, Associated Press, for the above information)

+ NASA called off a planned spacewalk on June 24 due to a malfunction in astronaut Tracy Dyson’s spacesuit. Dyson and her crewmate Mike Barratt were preparing to exit the International Space Station to conduct maintenance when a water leak was detected in Dyson’s suit cooling unit. This unit is crucial for maintaining a comfortable temperature during spacewalks. The leak occurred just after the suits were switched to battery power, prompting NASA to abort the mission. Although Dyson reported feeling a bit warm and expressed concerns about potential water damage to electrical connectors, both astronauts were safe throughout the incident. This cancellation follows a similar recent setback on June 13, involving a spacesuit issue, and it raises questions about the potential impact on the return schedule of Boeing’s Starliner capsule. (ANS thanks Jackie Wattles, CNN, for the above information)

+ NASA astronauts Suni Williams and Butch Wilmore, who flew Boeing’s Starliner capsule to the International Space Station (ISS), have had their return to Earth delayed multiple times due to issues with the spacecraft. Originally planned to stay for about a week, their mission has been extended indefinitely as NASA and Boeing investigate a slow helium leak and malfunctioning thrusters discovered after reaching orbit. The latest delay was announced last week, with no new return date set yet. Despite these issues, the astronauts are assisting with tasks and conducting tests on the ISS, where they are accommodated with sufficient supplies. NASA is taking a cautious approach, allowing data to drive decisions about managing the leaks and thruster performance. This mission aims to certify the Starliner for future routine flights, similar to SpaceX’s Crew Dragon service for NASA. (ANS thanks Denise Chow, NBC News, for the above information)

Starliner Brings Another Ham to ISS

Working around multiple helium leaks and thruster problems, the crew of Boeing’s Starliner spacecraft wrapped up a challenging rendezvous and a delayed-but-successful docking with the International Space Station Thursday in a major milestone for the new ship’s first piloted test flight.

With commander Barry “Butch” Wilmore and co-pilot Sunita Williams, KD5PLB, monitoring the Starliner’s automated approach, the Starliner’s docking mechanism engaged its counterpart on the front of the station’s forward Harmony module at 17:34 UTC on June 8 as the two spacecraft were sailing 260 miles above the Indian Ocean.

After extensive checks to verify an airtight seal, hatches were opened and Wilmore and Williams floated into the lab complex to an enthusiastic welcome from the seven Expedition 71 crew members: cosmonauts Oleg Kononenko, RN3DX, Nicolai Chub and Alexander Grebenkin, RZ3DSE, along with NASA astronauts Matthew Dominick, KCØTOR, Michael Barratt, KD5MIJ, Jeanette Epps, KF5QNU, and Tracy Dyson.

Wilmore and Williams plan to spend about a week aboard the outpost before returning to Earth aboard the Starliner. While they’re there, the station crew will install a replacement urine processor pump module that was loaded aboard the Starliner at the last minute to fix the lab’s water recycling system and allow normal use of the toilet in the U.S. segment of the station.

Running years behind schedule after multiple problems that cost Boeing some $1.4 billion to correct, the Starliner was launched Wednesday with a known helium leak in the system used to pressurize the spacecraft’s propulsion system. Launch had been delayed a month, in part because of work to confirm the ship could safely be launched with the leak as is.

After reaching orbit, two more helium leaks developed that prompted flight controllers to close valves leading to the affected plumbing, or manifolds, while they analyzed leak rates and potential work arounds. Closing the manifolds took down five of 28 reaction control system jets in the ship’s service module and three of 20 more powerful “OMAC” thrusters.

Docking had to be delayed because five RCS jets were “deselected” by the capsule’s flight software when telemetry showed they were not performing exactly as expected. It was unclear if there would be sufficient maneuverability for the docking to proceed.

Throughout the process, Wilmore flew the Starliner manually, holding position about 650 feet from the space station. When ground teams concluded the spacecraft had enough thruster redundancy to proceed, the Starliner’s automated control system took over and flew the ship in for a problem-free docking.

As if the team hadn’t had enough problems to deal with, a fourth and a fifth helium leaks were detected after docking. In any case, per standard procedure, flight controllers closed all the Starliner’s helium manifolds after the linkup to prevent any residual leakage while attached to the station.

Despite the leaks, NASA officials said more than enough helium remains on board to ensure a safe return to Earth at the end of a normal-duration or even extended mission.

On June 14, NASA and Boeing teams pushed back the target undocking and landing date for the Starliner spacecraft from the International Space Station by four days. They shifted from June 18 to now no earlier than June 22.

The reason for the extended stay is in part due to a need to gather more information about the Starliner capsule with the benefit of having an astronaut crew assigned to study aspects of the spacecraft with additional detail.

The helium leaks are all located in the Starliner’s drum-shaped service module, which is discarded to burn up in the atmosphere before the crew capsule re-enters for landing. Thus, there is no possibility of post-flight analysis of the problems.

Voyager 1 is Back To Life, But For How Long?

NASA engineers have succeeded in breathing new life into Voyager 1, the spacecraft launched in 1977 and once again communicating after it went silent seven months ago. But now comes another challenge: Keeping Voyager 1 scientifically useful for as long as possible as it probes a realm where no spacecraft has gone before.

Voyager 1 and its twin, Voyager 2, are treasured at NASA not only because they have sent home astonishing images of the outer planets, but also because in their dotage, they are still doing science that can’t be readily duplicated.

They are now in interstellar space, far beyond the orbits of Neptune and Pluto. Voyager 1 is more than 15 billion miles from Earth and Voyager 2 nearly 13 billion miles. Both have passed the heliopause, where the “solar wind” of particles streaming from the sun terminates.

“They’re going someplace where we have nothing, we have no information,” NASA Deputy Administrator Pam Melroy said. “We don’t know anything about the interstellar medium. Is it a highly charged environment? Are there a lot of dust particles out there?”

Even as the Voyagers continue their journeys, engineers and scientists at the NASA Jet Propulsion Laboratory in Pasadena, Calif. are mourning the loss of Ed Stone, the scientist who guided the mission from 1972 until his retirement in 2022. Stone, a former director of JPL, died June 9 at the age of 88.

Voyager 1 has four scientific instruments still operational in this extended phase of its mission, but it suddenly ceased sending intelligible data on Nov. 14. A “tiger team” of engineers at JPL spent the ensuing months identifying the problem — a malfunctioning computer chip — and restoring communication.

What no one can change, though, is the mortality of a spacecraft with a limited power supply. Voyager 1 is running on fumes, or, more precisely, on the dwindling power from the radioactive decay of plutonium. The Voyagers use a radioisotope thermoelectric generator. But an RTG doesn’t last forever. Voyager 1 and Voyager 2 will eventually go silent as they continue to cruise the galaxy.

“At some point, we’ll have to start turning off the science instruments one by one,” project scientist Linda Spilker said. “Once we’re out of power, then we can no longer keep the spacecraft pointed at the Earth. And so [the Voyagers] will then continue on as what I like to think of as our silent ambassadors.”

In a sense, this is all a bonus because the primary mission for the two Voyagers was the exploration of the outer planets. Both visited Jupiter and Saturn, and Voyager 2 went on to Uranus and Neptune in what was known as the “Grand Tour” of the outer solar system, enabled by a rare orbital arrangement of the planets. The Voyagers delivered spectacular close-up images of the outer planets, and the mission ranks among NASA’s greatest achievements.

The gravitational slingshot from the planetary encounters sent Voyager 1 out of the elliptical plane of the solar system and did the same to Voyager 2 in a different direction.

About four years ago, Voyager 1 encountered something unexpected — a phenomenon scientists have dubbed a pressure front. Jamie Rankin, deputy project scientist, said the instruments on the spacecraft picked up a sudden change in the magnetic field of the interstellar environment, as well as a sudden increase in the density of particles.

What exactly caused this change remains unknown. But NASA scientists are eager to get all the data flowing normally again to see whether the pressure front is still detectable.

AMSAT Mail Alias Service to End August 1, 2024

A long-standing member service, the AMSAT Mail Alias Service is scheduled to end on August 1, 2024. A mail alias on AMSAT.ORG permitted people to send an email to members without knowing their actual internet email address. They just needed to know their amateur radio callsign.

Unfortunately, the unchecked rise in domain name hacking and email account high-jacking has made it impossible to sustain this service at a cost-effective level. The number of [email protected] email accounts that had been hijacked and converted to zombie spam accounts over the years had led many internet service providers and gateway centers to ban all @amsat.org email addresses, including those business accounts of AMSAT officers and officials. The tireless efforts of AMSAT’s all volunteer IT staff has worked for years to repair much of the damage, but AMSAT still get complaints from members who are not getting their personal emails, ANS bulletins or AMSAT-BB posts because of persistent delivery problems.

It has come to the point where the AMSAT volunteer IT staff can no longer keep up with the maintenance requirements to keep the alias mail list clean and to work with email gateways to remove blocks. And, after considerable investigation into alternative paid email services, AMSAT leadership decided that the money required to keep an email alias system alive would be better spent on building and flying satellites for its members.

Persons using the Mail Alias Service should begin to migrate to different email accounts so they do not lose receipt of personal emails, AMSAT News Service Weekly Bulletins, AMSAT-BB posts, or official messages from AMSAT itself. Members are especially asked to make sure they are NOT using a [email protected] as their registered email address in the AMSAT membership portal. Members can easily change their registered member email address by logging into the portal and updating their profile.

The 2024 AMSAT Field Day Rules

The AMSAT Field Day 2024 event is open to all Amateur Radio operators. Amateurs are to use the exchange as specified in ARRL rules for Field Day. The AMSAT competition is to encourage the use of all amateur satellites, both analog and digital. Note that no points will be credited for any contacts beyond the ONE allowed via each single-channel FM satellite. Operators are encouraged not to make any extra contacts via theses satellites (Ex: SO-50). CW contacts and digital contacts are worth three points as outlined below.

Analog Transponders

ARRL rules apply, except:

Each phone, CW, and digital segment ON EACH SATELLITE TRANSPONDER is considered to be a separate band.
CW and digital (FT-4, RTTY, PSK-31, etc.) contacts count THREE points each.
Stations may only count one (1) completed QSO on any single channel FM satellite. If a satellite has multiple modes such as V/u and L/s modes both turned on, one contact each is allowed. If the both ISS stations are operational, one QSO on each mode (1 phone and 1 digital), Contacts with the ISS crew will count for one contact if they are active. Greencube (1 digital).
The use of more than one transmitter at the same time on a single satellite transponder is prohibited.

Digital Transponders

Satellite digipeat QSO’s and APRS short-message contacts are worth three points each, but must be complete verified two-way exchanges. The one contact per FM satellite is not applied to digital transponders.

The use of terrestrial gateway stations or internet gateways (i.e. EchoLink, IRLP, etc.) to uplink/downlink is not allowed.

For ‘Store and Forward’ hamsats, each satellite is considered a separate band. Do not post “CQ” messages. Simply upload ONE greeting message to each satellite and download as many greeting messages as possible from each satellite. The subject of the uploaded file should be posted as Field Day Greetings, addressed to ALL. The purpose of this portion of the competition is to demonstrate digital satellite communications to other Field Day participants and observers. Do not reply to the Field Day Greetings addressed to ALL.

The following uploads and downloads count as three-point digital contacts.

(a) Upload of a satellite Field Day Greetings file (one per satellite).

(b) Download of Satellite Field Day Greetings files posted by other stations. Downloads of non-Field Day files or messages not addressed to ALL are not to be counted for the event. Save DIR listings and message files for later “proof of contact.”

You may make contacts with GreenCube, IO-117, and each one will count as 3 points as do other digital contacts.

Please note AMSAT uploaded messages do not count for QSO points under the ARRL rules.

Sample Satellite Field Day Greetings File:

KK5DO FD EL29 class 2A 20 participants

Note that the message stated the call, operating class, where they were located (the grid square) and how many operators were in attendance.

Operating Class

Stations operating portable and using emergency power (as per ARRL Field Day rules) are in a separate operating class from those at home connected to commercial power. On the report form simply check off Emergency or Commercial for the Power Source and be sure to specify your ARRL operating class (2A, 1C, etc.).

AND FINALLY…

The Satellite Summary Sheet should be used for submission of the AMSAT Field Day competition and be received by KK5DO (e-mail) by 11:59 P.M. CDT, Monday, July 23, 2024. This year, we are using the same due date as the ARRL. The only method for submitting your log is via e-mail to [email protected] or [email protected]. I have not had a mail-in entry in a very long time.

Add photographs or other interesting information that can be used in an article for the Journal.

You will receive an e-mail back (within one or two days) from me when I receive your e-mail submission. If you do not receive a confirmation message, then I have not received your submission. Try sending it again or send it to my other e-mail address.

Certificates will be awarded for the first-place emergency power/portable station at the AMSAT General Meeting and Space Symposium in the fall of 2024. Certificates will also be awarded to the second and third place portable/emergency operation in addition to the first-place home station running on emergency power. A station submitting high, award-winning scores will be requested to send in dupe sheets for analog contacts and message listings for digital downloads.

You may have multiple rig difficulties, antenna failures, computer glitches, generator disasters, tropical storms, and there may even be satellite problems, but the goal is to test your ability to operate in an emergency situation. Try different gear. Demonstrate satellite operations to hams that don’t even know the HAMSATS exist. Test your equipment. Avoid making more than ONE contact via the FM-only voice HAMSATS or the ISS, and enjoy the event!

Satellite Shorts From All Over

+ The U.S. spacewalk 90 planned for Thursday, June 13 at the International Space Station did not proceed as scheduled due to a spacesuit discomfort issue. NASA astronauts Tracy C. Dyson and Matthew Dominick, KCØTOR, completed taking off their spacesuits about an hour before the crew was anticipated to exit the Quest airlock. With consideration to NASA’s Boeing Crew Flight Test and other spaceflight operations, the next spacewalk will be Monday, June 24, followed by another on Tuesday, July 2, as was previously planned. The June 24 spacewalk will focus on radio frequency group hardware removal, while the content of the July 2 spacewalk is under evaluation and will be shared as available. The crew members on the station are healthy, and spacesuits are functioning as expected. [As always, if there is an EVA, a docking, or an undocking; the ARISS radios are turned off as part of the safety protocol. ANS thanks NASA for the above information.]

+ AMSAT-DL is organizing a symposium, flea market and general meeting in the radome of the Bochum Observatory, Germany on September 20-22, 2024. The radome will once again be dedicated to satellite and space research. AMSAT Deutschland e.V. and the Bochum Observatory are taking the positive experience of the anniversary conference in 2023 as an opportunity to inform AMSAT members and other space enthusiasts about current and future prospects for national and international space projects with a varied program. As the Radom is also the location of ESA’s education office in Germany (esero Germany), a goal is to make the symposium even more attractive in future and at the same time focus even more on current European space travel. [ANS thanks AMSAT-DL for the above information.]

+ SpaceX’s enormous rocket took off again from South Texas on June 6, this time with the sole goal of bringing both the booster and ship softly back to Earth in (roughly) single pieces. An on-time launch of the world’s most powerful rocket delivered excitement from start to finish. Despite an engine out on launch and landing (with 33 engines total, Superheavy doesn’t care), the first stage was able to complete a nominal ascent, hot-staging, temporary hot-staging ring jettison, boost back, and landing burn—all with enough precision that previously deployed buoy cams were able to capture its soft splashdown. [ANS thanks The Orbital Index for the above information.]

+ Russian cosmonaut and ISS commander Oleg Konenko became the first person to reach 1,000 cumulative days in space as of June 4. The milestone comes amid his fifth flight to space and during his third stint as the commander of the ISS. His most recent trip to the orbiting laboratory began with a launch aboard the Soyuz MS-24 spacecraft on Sept. 15, 2023, alongside cosmonaut Nikolai Chub and NASA astronaut Loral O’Hara, KI5TOM. He’s scheduled to return with Chub and NASA astronaut Tracy Dyson in September 2024. [ANS thanks Spaceflight Now for the above information.]

Setting Up Your Own Satellite Ground Station with SatNOGS

Robert Theiss, W5ITR, had the pleasure of interviewing Dan White, ADØCQ, from the Libre Space Foundation at the 2024 Dayton Hamvention about their innovative SatNOGS project. This initiative enables anyone to set up a satellite ground station, collect valuable data, and contribute to global satellite operations. You can watch the interview here on the Digital Rancher YouTube channel: https://www.youtube.com/watch?v=edNfD_YXZps

Dan explained that SatNOGS provides detailed blueprints and documentation for building a satellite ground station from scratch. The foundation offers the necessary software, identifies accessible hardware, and maintains the infrastructure that allows citizen scientists to engage in satellite-related sciences. Their vision of making outer space open and accessible through open-source technology is truly inspiring.

Setting up a basic SatNOGS station is surprisingly straightforward. All you need is a Raspberry Pi and an RTL-SDR dongle. Dan explained the process: the Libre Space Foundation provides a ready-to-use image for the Raspberry Pi, which includes the operating system and necessary configurations. You just create an account, register your station, and schedule a test observation.

For those looking to enhance their setup, SatNOGS offers extensive documentation on building antennas and integrating additional components like low noise amplifiers and band pass filters. Although they plan to offer kits in the future, you can currently follow the detailed instructions and suggested links available on the SatNOGS Wiki: https://wiki.satnogs.org.

One of the most fascinating aspects of SatNOGS is its network of interconnected ground stations. Once your station is set up, it can schedule satellite passes and collect data, even while you’re asleep. This data is shared across the network, allowing other users to access it, and vice versa. This system ensures continuous monitoring and data collection, maximizing the utility of each station.

The SatNOGS community is highly active and supportive. The forums on the Libre Space Foundation’s website are a great resource for troubleshooting, sharing experiences, and staying updated on new satellite launches and developments.

For those interested in taking their ground station to the next level, SatNOGS supports more advanced setups with full azimuth and elevation rotators and larger antennas. These setups, while more costly, significantly increase data collection capabilities and overall performance. The Raspberry Pi used in the basic setup can interface with these advanced systems, allowing for automated tracking and data collection.

Dan shared insights into practical aspects such as bandwidth requirements and equipment wear and tear. While the data collected by a SatNOGS station can be bandwidth-intensive, there are settings to optimize for lower bandwidth situations by disabling audio uploads. Additionally, proper setup and maintenance of antennas and rotators can ensure long-term operation without significant issues.

The Libre Space Foundation and its SatNOGS project provide a unique opportunity for anyone interested in satellite and space communications to get involved. Their open-source approach and comprehensive support make it accessible even for beginners. Setting up your own satellite ground station is a rewarding experience, contributing to global space exploration and satellite communication.

SpaceX Aims for Successful Reentry in Fourth Starship Test Flight

SpaceX is targeting June 6th for the fourth test flight of its Starship megarocket, aiming to demonstrate the rocket’s ability to survive reentry, according to founder and CEO Elon Musk. This objective marks a crucial step in proving the reusability of the world’s most powerful rocket, following three prior test flights that showcased its capacity to reach space.

On May 20th, SpaceX carried out a crucial test by loading over 10 million pounds of super-cold methane and liquid oxygen propellants into the Super Heavy booster and the Starship upper stage. This practice countdown, which concluded before engine ignition, was one of the last major tests before the rocket’s flight. Following the test, the launch team drained the propellants, and ground crews removed the Starship upper stage to perform additional work on its heat shield.

The next steps include installing the rocket’s self-destruct mechanism, to be used if the vehicle deviates off course, and securing a commercial launch license from the Federal Aviation Administration (FAA). The FAA is reviewing the results of SpaceX’s previous Starship test flight in March, which was classified as a mishap after the vehicle lost control and disintegrated during reentry.

SpaceX has requested the FAA approve the upcoming launch before the mishap investigation concludes, arguing that the previous flight did not pose a public safety risk. An FAA spokesperson indicated that this could expedite the licensing process if no public safety issues are identified.

Meanwhile, SpaceX is preparing hardware for multiple rockets scheduled to fly later this year and building additional launch sites in Texas and Florida to support an increased launch frequency. However, significant design challenges remain before Starship becomes fully operational.

Unlike the March test flight, which included several experiments such as payload bay door operations and liquid oxygen transfer, the upcoming mission will concentrate on controlling the reentry of both the Super Heavy booster and the Starship upper stage. Both components broke apart during descent in the last flight.

SpaceX aims for the Super Heavy booster, named Booster 11, to achieve a controlled splashdown in the Gulf of Mexico, while the Starship upper stage, known as Ship 29, will attempt to survive the extreme reentry conditions. The rocket is equipped with about 18,000 hexagonal heat-absorbing ceramic tiles to protect its stainless-steel structure during reentry, where temperatures can reach approximately 2,600°F (1,430°C).

Musk has indicated that, assuming a successful splashdown, SpaceX could attempt landing a Super Heavy booster back at the Texas launch pad as early as the fifth test flight later this year. However, due to harsher reentry conditions from orbital velocity, landing the Starship upper stage might take longer.

NASA, which selected Starship to ferry astronauts to and from the Moon for its Artemis program, is closely monitoring these developments. A critical milestone for NASA is the in-orbit engine restart, necessary for guiding Starship towards controlled reentry and future lunar missions. While this capability will not be tested on the next flight, achieving reliable engine performance remains a primary focus.

“For us, primarily, it’s the successful light of those Raptor engines and achieving main stage with all of them on Booster 11,” said Lisa Watson-Morgan, manager of NASA’s Human Landing System. The next flight aims to ensure consistent engine performance, crucial for SpaceX and NASA’s lunar ambitions.

Reigniting Raptor engines in space is essential for future missions, but SpaceX is taking a step-by-step approach. “If we can’t light all 33 engines on the booster, and if we can’t light all six engines on the ship, then we’re going to have trouble getting to where we need to go,” Watson-Morgan said. “So it’s basically a building-block approach.”

As SpaceX prepares for its fourth Starship test flight, the focus on surviving reentry represents a critical hurdle in its mission to develop a fully reusable rocket system capable of reaching, and returning from, space.

Satellite Shorts From All Over

+ China’s Chang’e 6 probe is set to land on the far side of the moon this weekend, aiming to return lunar samples to Earth. Launched on May 3, the robotic mission entered lunar orbit five days later and is targeting a touchdown on Saturday night, June 1st, for those in North America. The mission will study its landing area in the South Pole-Aitken Basin, collecting samples over three days before the ascent module returns to lunar orbit. These samples will be transferred to a return-to-Earth module, with a scheduled Earth landing on June 25. Once returned, the samples will be examined in Beijing and made available to the scientific community for research. This mission builds on the success of Chang’e 5, which returned 61 ounces of lunar material in 2020, and aims to provide insights into the moon’s magmatic processes and mantle properties. (ANS thanks Leonard David, Space.com, for the above information)

+ Blue Origin resumed crewed spaceflights on May 19 after a nearly two-year hiatus following a rocket mishap in 2022, which left Virgin Galactic as the sole operator in the suborbital tourism market. Among the six passengers was Ed Dwight, a former Air Force pilot who had been poised to become NASA’s first Black astronaut in the 1960s. Dwight, at 90 years old, became the oldest person to go to space, expressing the profound impact of the experience. Despite one of the capsule’s parachutes failing to fully inflate, the mission was deemed a success, and all passengers returned safely. This flight marks the seventh human mission for Blue Origin, highlighting its ambitions for future space endeavors. The company has now flown 37 people aboard its New Shepard vehicle, named after the first American in space, Alan Shepard. (ANS thanks Issam Ahmed, Phys.org, for the above information)

+ Rocket Lab successfully launched a small Earth-observation satellite for NASA on May 25, marking the company’s 48th liftoff. The Electron rocket lifted off from New Zealand at 3:41 a.m. EDT, carrying the first of two CubeSats for NASA’s PREFIRE (Polar Radiant Energy in the Far-InfraRed Experiment) mission. This satellite, deployed into orbit 53 minutes post-launch, will measure heat loss from Earth’s polar regions, a critical factor in understanding climate change. A second PREFIRE satellite will launch within three weeks, with both CubeSats set to operate in 326-mile-high circular orbits. The PREFIRE mission aims to enhance climate models by systematically measuring thermal infrared radiation over the Arctic and Antarctica. Notably, Rocket Lab’s Electron rocket, while designed for reusability, executed this mission without a recovery component. (ANS thanks Mike Wall, Space.com, for the above information)

+Voyager 1 has resumed transmitting science data from two of its four operational instruments after a computer issue arose in November 2023. The mission team is working on recalibrating the remaining two instruments, with plans to complete this in the coming weeks. This progress follows a five-month troubleshooting effort, during which the spacecraft began sending back usable engineering data. On May 17, commands were successfully sent to the 46-year-old spacecraft, located over 15 billion miles from Earth, enabling it to resume sending science data. The plasma wave subsystem and magnetometer are now operational, while efforts continue on the cosmic ray subsystem and low energy charged particle instrument. Launched in 1977, Voyager 1 and its twin, Voyager 2, are NASA’s longest-operating spacecraft and the first to explore beyond the heliosphere, having flown by Jupiter, Saturn, and, in Voyager 2’s case, Uranus and Neptune.

AMSAT at Hamvention

This issue of the AMSAT News Service bulletins is being produced at the AMSAT booth at Hamvetion 2024 in Xenia, Ohio. AMSAT has a major presence at Hamvention, with booths devoted to teaching satellite basics, membership recruitment, the AMSAT Store, Engineering, Education, and the Ambassador program.

Traffic was heavy on Friday morning, May 17, as soon as Hamvention opened its doors. While some came directly to the AMSAT booth with their questions, or to make purchases at the Store, many other ham attendees were attracted by the displays as they wandered through the several Hamvention venues.

Volunteer members of the AMSAT Engineering team were on hand to show off models of the GOLF-Tee and Fox Plus satellites currently under construction. Engineering team members also discussed various projects that are part of the ASCENT program, developing possible components for future satellites.

At the Education booth, Cubesat SIM models were transmitting actual telemetry and slow-scan TV data across the table, demonstrating how these tools can be assembled and used in classrooms and other settings to provide hands-on instruction in satellite basics.

At the “Beginners Corner,” experienced satellite operators answered questions and helped the curious to understand how easy and exciting it is to get started in this fascinating aspect of the amateur radio hobby. Rain on Friday morning prevented live satellite demonstrations, but these took place as satellite passes and Hamvention circumstances permitted on Saturday and Sunday.

The sixteenth annual joint AMSAT/ TAPR Banquet was held on Friday evening at the Kohler Presidential Banquet Center in Kettering, Ohio, just south of Dayton. This year’s banquet speaker was Bill Reed, NX5R, AMSAT PACSAT Project Manager, who highlighted the forthcoming PACSAT digital communications payload. This payload is drawing on lessons learned from previous digital satellites to provide smoother operations for users in the future.

The AMSAT Forum was held on Saturday afternoon. Robert Bankston KE4AL, AMSAT President, highlighted recent activities within AMSAT and discussed some of our challenges, accomplishments, projects, and late breaking news (See following story). Jerry Buxton, NØJY, AMSAT Vice President for Engineering, provided a video status update about upcoming satellite missions currently in development. Alan Johnston, KU2Y, AMSAT Vice President Education Relations, spoke about opportunities for using the AMSAT CubeSat Simulator in educational settings. Drew Glasbrenner, KO4MA, Vice President Operations, briefed those attending on the status of current satellites. And Frank Karnauskas, N1UW, Vice President of AMSAT Development, reported on the AMSAT Youth Initiative and its features.

Attendance was steady at all AMSAT exhibits throughout the Hamvention weekend, and satellite operators enjoyed meeting, fact to face, the voices and callsigns encountered on the satellites.

Multiple QO-100 DX-Peditions to VO1

This week sees three separate groups operating from just outside the coverage footprint of the QO-100 satellite.

From Newfoundland the geostationary QO-100 satellite is nominally 1 degree below the horizon. After 5 years in orbit and much speculation, three groups are in the St. John’s area to try operating QO-100 with its S band uplink and 10GHz downlink.

First in Newfoundland was Gopan, M0XUU. He was operating with a 0.8m dish from just north of the harbor entrance and updates could be found on the QO-100 DX Club web site. https://qo100dx.club/ Despite frequency periods of no signal or deep QSB, Gopan managed to work stations via FT8, FT4, and CW. After a week on the air as VO1/M0XUU, Gopan left Newfoundland on May 15.

Arriving Monday 13 May and remaining until to Friday 17, was a Canadian team with a 1.8m dish and up to 100W. Poor weather hampered their operations. Details of the operation by Stefan Wagener, VE4SW, and John Langille, VE1CWJ, can be found at the QRZ.com page for special callsign, VO100QO at https://www.qrz.com/db/VO100QO

Finally, Graham Shirville, G3VZV, and David Bowman, G0MRF, arrived on Wednesday, May 15 with two sets of equipment and were active as VO1/G3VZV and VO1/G0MRF. They will fly back to the UK early Sunday, May 19. Operating from the old lighthouse keepers bungalow on the southern side of the harbor entrance, GN37PN85, they attempted working all modes including an attempt with DATV with a 175W S band amplifier. When not actively on the bands, a personal beacon was operating on 10489.539 MHz in CW to act as a propagation indicator.

Lost and Found: Missing Satellite Rediscovered

After 25 years lost in the vastness of space, a missing satellite has finally been located, highlighting the challenges of tracking the multitude of objects orbiting Earth. The rediscovery sheds light on the difficulty of monitoring the approximately 27,000 objects that populate Earth’s orbit, a number that continues to grow with each rocket launch and satellite deployment.

The satellite in question, the Infra-Red Calibration Balloon (S73-7), was part of the United States Air Force’s Space Test Program and was launched in 1974. Its purpose was to serve as a calibration target for remote sensing equipment, but a deployment failure left it adrift as space debris. Despite initial attempts to track its whereabouts, it vanished from ground-based sensors in the 1990s, only to resurface last month.

The Air Force’s KH-9 Hexagon satellite deployed the tiny IRCB (S73-7) satellite in 1974. (Illustration: U.S. Air Force)

Jonathan McDowell, an astrophysicist from the Harvard-Smithsonian Center for Astrophysics, discovered the satellite’s reappearance while reviewing archival data. He explained that the satellite’s low radar cross section and possible malfunctioning equipment made it difficult to detect. This underscores the challenges faced by ground-based radar and optical sensors tasked with monitoring objects in orbit.

Tracking objects in space is akin to air traffic control, with sensors relying on identifying the orbit of moving objects and matching them with designated satellite orbits. However, this becomes increasingly complex as Earth’s orbit becomes more congested, particularly in geostationary orbit where monitoring is hindered by a lack of radars positioned precisely on the equator.


A screenshot of a screenshot of a graph Description automatically generated

The Department of Defense’s Space Surveillance Network currently tracks over 27,000 objects, predominantly defunct satellites and debris. As the number of satellites and rocket launches continues to rise, maintaining accurate tracking becomes crucial to mitigate the risk of collisions and space debris hazards.

While the rediscovery of the missing satellite serves as a reminder of the challenges of space tracking, it also underscores the importance of continued efforts to monitor and manage Earth’s orbital environment. With technology evolving and space activity increasing, effective space surveillance remains paramount to ensure the safety and sustainability of activities in Earth’s orbit.

Starliner: A Decade of Challenges

Boeing is delaying its first flight with humans on its Starliner spacecraft yet again, the company said on May 14. The launch, which has been delayed for years and was most recently scheduled for May 18, was pushed back until Tuesday afternoon, May 21 at the earliest because of a helium leak.

Boeing’s Starliner spacecraft marks the culmination of a tumultuous journey fraught with setbacks and challenges. What’s surprising isn’t merely Boeing’s eventual loss in the commercial crew space race to SpaceX but rather the fact that Boeing managed to reach this point at all.

The story traces back a decade when NASA’s human spaceflight leaders convened to select a replacement vehicle for the retired Space Shuttle. Boeing emerged as the frontrunner, backed by its illustrious history in spaceflight. However, the eventual decision to award contracts to both Boeing and SpaceX marked the beginning of Boeing’s struggle to adapt to the demands of a fixed-price environment.

Unlike SpaceX, which was already immersed in multiple space projects, Boeing found itself grappling with a new paradigm. Accustomed to cost-plus contracts, where expenses could be billed to the government, Boeing now faced the challenge of delivering a spacecraft within strict budget constraints. This shift exposed deep cultural and structural inefficiencies within the company.

Boeing’s difficulties were compounded by technical hurdles, particularly in software development and propulsion. Fragmented software teams and strained relationships with suppliers like Aerojet Rocketdyne hindered progress. The consequences of these challenges became evident during Starliner’s ill-fated uncrewed test flight in 2019, marred by critical software errors and propulsion anomalies.

While Boeing struggled, SpaceX surged ahead, buoyed by its vertically integrated approach and a culture of innovation. SpaceX’s success underscored the shortcomings of Boeing’s traditional aerospace model, further exacerbated by broader crises within Boeing’s aviation division, notably the 737 MAX disasters and the COVID-19 pandemic.

Boeing’s tumultuous journey with Starliner offers valuable lessons about the perils of resisting change and the imperative of embracing innovation in the rapidly evolving space industry. Despite its setbacks, Boeing’s perseverance underscores the dedication of the engineers and technicians who tirelessly worked to bring Starliner to fruition.

Satellite Shorts From All Over

+ Congratulations to Maksym “Max” Romenskyy, SA5IKN, M0SKN, US6IKN, EI6KC, who has earned his THIRD satellite Worked All Zones (WAZ) award, this time as EI6KC #121. This is the first WAZ Satellite Award in Ireland. He is also the first in the world to complete three WAZ Satellite Awards from three different locations in three countries. He already holds a special plague “IN RECOGNITION OF WORLD # 1 SAT WAZ AWARD WITH TWO CALLS” for WAZ awards #40 as SA5IKN (38 zones) and #92 as MØSKN. (ANS thanks Max Romenskyy, US6IKN, for the above information.)

+ Since April 28, 2019, the Swiss satellite net on QO-100 has been a consistent weekly event, marking its fifth anniversary on the same date in 2024. Hosted by HB9RYZ initially and later by HB9TSI from Italy, the round convenes every Sunday at 9:00 p.m. on 10489.740 MHz, typically with 5 to 10 participants, though 15 joined for the anniversary round. Led by Paul, HB9DFQ, the round maintains a familiar format: participants check in, share station updates and radio experiences, delve into topics, and bid farewell. Despite no specific celebration planned, the anniversary drew a hearty attendance. Notable moments include Roman, HB9HCF’s reports from Antarctica during the pandemic, while regular attendees like IS0/HB9SJP and supportive listeners add to the camaraderie. The inaugural round was preserved on Soundcloud by HB9WDF, encapsulating the enduring spirit of this community gathering. (ANS thanks AMSAT-HB for the above information for the above information)

+ The recently released GreenCube BackPack antenna by Arrow Antennas, designed specifically for IO-117 satellite communication, can now be purchased from their website for $219. It boasts a three-piece split boom design and 15 UHF elements, along with a pre-assembled and pre-tuned Gamma Match compatible only with BNC connectors. Engineered for maximum gain and efficiency, the antenna utilizes aluminum Arrow Shafts for its elements and a 3/4″ square boom measuring 116.8″ in length. Mounting near its balance point is recommended due to its weight, and plastic tips ensure safety. While the foam handle grip can be removed using isopropyl alcohol, using the tripod hole for mounting is discouraged due to balance issues. Additionally, customers have the option to purchase a separate element set for cross-polarized antenna configuration, priced at $99.00.

+ Prof. Robert “Bob” Twiggs, KE6QMD, and a group of former students and colleagues are working on gathering and publishing a series of books on the history of the creation and adoption of the CubeSat. Take a look at the LinkedIn announcement here: https://lnkd.in/eNZgv6Tk. If this sounds like something you’d be interested in supporting, please take a look at our GoFundMe page here: https://www.gofundme.com/f/cubesat-history-project. The community’s response has been amazing! Over a hundred interviews were conducted, and countless images and documents from the earliest days of the CubeSat were collected! The result is that we have accumulated one of the most comprehensive histories of the CubeSat, with many unique, never-before-told stories! Reach out if you are interested in sponsoring the project to get a signed copy and your organization’s name in the book. Please email Dr. Aaron Zucherman at [email protected].

+ Last week, as Sol continues to edge into the most active phase of its 11-year cycle, multiple massive X-class solar flares (the largest an X5.8 flare) erupted from associated active sunspots, along with coronal mass ejections (CMEs) directed towards Earth. This sustained activity caused a G5 solar storm last weekend (NOAA’s space weather scales for reference), leading to aurorae visible from middle latitudes as far south as Puerto Rico in the US and all over Europe. This was one of the most powerful solar storms since an estimated X28-45 flare in 2003 contributed to the 2003 Halloween solar storms that damaged or interrupted services from multiple spacecraft, saturated measurement instruments, and made ISS astronauts shelter in the more shielded Russian segment.

+ Japan’s Moon Sniper, also known as SLIM, has astounded experts by surviving its third lunar night, despite not being designed for such harsh conditions. Initially landing near the Shioli Crater on January 19, the spacecraft encountered an anomaly during descent, landing on its nose and facing west, hindering its solar panels’ ability to generate power. However, Moon Sniper continues to defy expectations by waking up after each lunar night, transmitting new images before going back into hibernation. Despite enduring both the extreme cold of the lunar night and the searing temperatures of the lunar day, the spacecraft has maintained functionality, prompting close monitoring from the mission team to identify potential deteriorating components. As Moon Sniper enters hibernation again, the team plans to resume operations in May, expressing gratitude for ongoing support and even composing a song titled “15 Degree Slope” to commemorate the mission’s unexpected journey.
