India Launches SpaDeX Satellites with Amateur Radio Experiment

India has launched the SpaDeX mission, designed to perform the country’s first autonomous docking experiment in space. A Polar Satellite Launch Vehicle (PSLV-C60) carried two SpaDeX satellites into orbit from the Satish Dhawan Space Centre in Sriharikota, India on December 30, 2024, at 11:30 a.m. EST (1630 UTC). The Indian Space Research Organisation (ISRO) sees this mission as a step toward supporting future Moon missions and building a space station.

The Space Docking Experiment (SpaDeX) consists of two 220-kilogram (485 pound) satellites, the Target and Chaser, which will test rendezvous and docking procedures. ISRO Chairman S. Somanath confirmed the satellites were placed in the correct orbit after launch. The first docking attempt is expected to occur in the next several days. The mission will assess the transfer of power between the docked spacecraft and evaluate dual-spacecraft control capabilities.

In addition to the docking experiment, the mission includes the POEM-4 (PS4-Orbital Experimental Module), which carries 24 payloads. These include a robotic arm demonstration and a debris capture manipulator. The robotic arm will test mobility for tasks in orbit, while the debris capture manipulator will attempt to retrieve tethered objects in an effort to address space debris.

One of the payloads aboard POEM-4 is the BGS ARPIT, an amateur radio project developed by the SJC Institute of Technology, the Upagrah Amateur Radio Club (VU2URC), and AMSAT-India to support educational activities and celebrate India’s 75th year of independence. This payload can transmit images via Slow Scan Television (SSTV), audio messages, and telemetry data on 145.870 MHz, and it also functions as an APRS digipeater on 145.825 MHz. Approved for IARU frequency coordination on December 22, 2024, BGS ARPIT completed its first SSTV transmission period on January 10th, with more trial periods sure to come soon.

The autonomous docking technology tested in SpaDeX is crucial for ISRO’s planned Chandrayaan-4 lunar mission, which aims to return samples from the Moon’s south pole. Docking capabilities will enable the transfer of samples to a return capsule in lunar orbit. This technology is also essential for the assembly and operation of the Bharatiya Antariksh Station, India’s planned space station.

The SpaDeX mission includes payloads developed by ISRO and collaborators from universities and startups. The experiments focus on areas like satellite servicing, space debris management, and educational outreach. The mission serves as a platform to advance technologies needed for India’s space exploration goals.

Parker Solar Probe Achieves Closest-Ever Approach to the Sun

NASA’s Parker Solar Probe reached a significant milestone on December 24, 2024, by coming within 3.8 million miles of the sun’s surface—the closest a human-made object has ever traveled toward a star. The spacecraft confirmed its survival through a signal received at the Johns Hopkins Applied Physics Laboratory (APL) on December 26. This marks another step forward in the mission’s effort to study the sun and its influence on the solar system. The probe, traveling at 430,000 miles per hour (692,000 kilometers per hour), continues to push the limits of solar exploration.

The mission allows the spacecraft to gather data from regions of the sun that were previously out of reach. Nicky Fox, associate administrator for NASA’s Science Mission Directorate, said, “By studying the sun up close, we can better understand its impacts throughout our solar system, including on the technology we use daily on Earth, as well as learn about the workings of stars across the universe.” This close approach opens the door for new measurements that could refine knowledge about solar wind, coronal heating, and other fundamental processes.

Launched in 2018, the Parker Solar Probe used seven Venus flybys to adjust its orbit and approach the sun. Its current orbit brings it near the sun every three months. A carbon foam heat shield, designed to withstand temperatures up to 2,600°F (1430°C), protects the spacecraft’s instruments, which remain at a stable temperature. During its latest encounter, the shield endured temperatures of 1,800°F (980°C), demonstrating the durability of its design and construction.

The spacecraft has already provided valuable data about solar phenomena. It has observed magnetic field structures called switchbacks, which help explain plasma heating and acceleration. Adam Szabo, mission scientist at NASA’s Goddard Space Flight Center, noted, “This close approach will give us more data to understand how the solar wind is accelerated closer in.” Measurements from within the solar corona offer new perspectives on how energy and particles move through this region.

The Parker Solar Probe has also contributed to studies of Venus, detecting thermal emissions from its surface and capturing images of its orbital dust ring. These observations highlight the spacecraft’s ability to gather insights beyond its primary mission. Data from the recent solar pass will soon be transmitted to Earth, providing additional information for researchers.

Future solar passes are scheduled for March 22 and June 19, 2025. Ralph Semmel, John Hopkins Applied Physics Laboratory Director, emphasized the team’s efforts, stating, “Their incredible technological breakthroughs enabled this amazing mission, and they have delivered critical new insights that are revolutionizing our understanding of heliophysics and space weather.” As part of NASA’s Living With a Star program, the Parker Solar Probe continues to investigate the relationship between the sun and the Earth, providing valuable knowledge for science and society.

3D-Printed Helicone Antenna Tested for L-Band Weather Satellites

Gabe Emerson, KL1FI, the creator behind the YouTube channel saveitforparts has unveiled a new video highlighting a 3D-printable helical antenna for receiving weather data from polar-orbiting L-band satellites such as NOAA and Meteor. Designed by a user named t0nito, the 1.7 GHz HRPT Helicone Antenna design is freely available on Thingiverse. Its compact size, straightforward assembly, and effective performance have the potential to make it a hit among amateur radio and satellite enthusiasts. The manual, instructions, and 3D printer files can be accessed at https://www.thingiverse.com/thing:6436342.

The video begins with the challenges encountered during the printing process. Early attempts at creating the antenna’s helical scaffold were plagued by warping issues in the support legs, resulting in several failed prints. To address this, the original 3D model was modified to include additional center supports, ensuring a stable print. Once the printing phase was complete, the assembly process involved wrapping wire around a two-inch pipe, crafting a reflector from metal window screen, and piecing everything together.

Testing the completed antenna proved its effectiveness. Using an RTL-SDR receiver and the SatDump software, Gabe successfully received data from the NOAA-18 HRPT satellite. By manually tracking the satellite, clear and detailed weather images, including nighttime thermal and infrared captures, were obtained, showcasing the antenna’s capability for high-quality data reception.

Designed with simplicity in mind, the Helicone antenna features a Right-Handed Circular Polarization (RHCP) configuration. Instead of relying on screws, the assembly process used hot glue and materials such as copper wire and sheet metal were sourced from everyday household items. These choices highlight its accessibility and affordability for hobbyists of all experience levels.

A performance comparison with an existing motorized tracking antenna revealed that the Helicone delivered comparable signal strength and image quality. While hand-tracking limited its functionality, its portability and ease of use were standout features. The lightweight design and straightforward assembly make it an ideal choice for amateur satellite enthusiasts looking for a practical and cost-effective solution.

Gabe concludes with praise for the antenna’s design and a call to action for viewers to try building one themselves. Future enhancements, such as integrating the Helicone with a motorized tracking system, are already being considered. For now, this detailed guide offers an excellent starting point for satellite hobbyists eager to explore affordable and efficient ways to receive weather data from orbiting satellites. The video titled “This 3D-Printed Satellite Antenna Is Fantastic!” can be found on the saveitforparts YouTube channel at https://youtu.be/PFQ6UKulxSo.

Cold War Mystery: Why Did Jimmy Carter Save the Space Shuttle?

The Space Shuttle program, an enduring symbol of American ingenuity, came perilously close to cancellation in the late 1970s. With the recent passing of Jimmy Carter at age 100, a fascinating story has resurfaced: how the 39th president, despite his well-known skepticism toward manned spaceflight, played a critical role in rescuing the program. This surprising twist in Cold War history highlights Carter’s pragmatism and the complex interplay between space exploration and geopolitics during his presidency.

This story first emerged during an interview with Chris Kraft, the former NASA Johnson Space Center director and a key architect of the Apollo program. Kraft recounted a critical 1978 meeting at NASA’s Houston headquarters, where dire financial constraints threatened the shuttle’s future. By then, the program was years behind schedule and hundreds of millions over budget. Faced with insufficient funding, NASA leaders considered two bleak options: securing a massive funding boost or relegating the shuttle to a mere research vehicle, incapable of fulfilling its ambitious mission to deliver payloads into orbit.

NASA Administrator Robert Frosch took the crisis to Washington, presenting President Carter with a stark ultimatum. Carter, known for his ambivalence toward manned spaceflight, surprised everyone by asking, “How much do you need?” According to Kraft, Carter’s decision was influenced by recent discussions with Soviet leader Leonid Brezhnev during Strategic Arms Limitation Talks (SALT). Carter reportedly highlighted the shuttle’s capability to verify Soviet compliance with arms agreements, a claim that underscored its national security value. While some details of this account remain disputed, Carter’s administration approved supplemental funding in 1979 and 1980, effectively saving the shuttle program.

Carter’s support for the shuttle is striking given his prior skepticism about its purpose. Early in his presidency, Carter dismissed the shuttle as a “contrivance to keep NASA alive.” His vice president, Walter Mondale, had also labeled the program a “senseless extravaganza.” Yet, by the late 1970s, escalating Cold War tensions reframed the shuttle’s significance. A key memo from the National Security Council emphasized the shuttle’s strategic value, arguing that canceling the program would undermine national pride and technological leadership.

While some NASA officials, including Shuttle Program Manager Robert Thompson, downplayed the risk of cancellation, the financial reality was grim. Development of critical components, such as the shuttle’s main engines and thermal protection tiles, was years behind schedule. Without Carter’s intervention, the shuttle might never have achieved its iconic role, flying 135 missions over three decades and laying the groundwork for the International Space Station.

In later reflections, Carter acknowledged his lack of enthusiasm for human space exploration but defended his decision to fund the shuttle. “I didn’t want to waste the money already invested,” he explained, noting that he discussed the shuttle’s peaceful intentions with Brezhnev during SALT II negotiations. While Carter’s motivations may have been rooted in pragmatism and diplomacy, his actions ensured the shuttle’s place in history. Despite his mixed legacy on space policy, Carter’s pivotal role in salvaging the shuttle underscores his capacity to recognize the broader implications of technological leadership during a turbulent era.

Satellite Shorts From All Over

+ Eutelsat’s OneWeb internet constellation experienced a 48-hour outage starting on December 31, 2024, due to a software glitch likely caused by failing to account for the leap year. The issue disrupted internet services but was resolved once the root cause, a ground segment software problem, was identified and addressed. Eutelsat operates over 630 satellites and has been building the OneWeb constellation since 2020 to provide global high-speed internet, targeting business clients rather than direct consumers. The company faced challenges in launching its satellites due to strained relations with Roscosmos following the Russian invasion of Ukraine, forcing it to rely on SpaceX and India for launches. Despite completing its constellation in 2023, regulatory delays in countries like India and Turkey have prevented global broadband coverage, leaving services available only in limited regions. Eutelsat is now planning to update its constellation with 100 new satellites by Airbus, aiming for improved reliability and full global service rollout by spring 2025. (ANS thanks Gizmodo for the above information)

Five CubeSats Successfully Deployed from “Kibo” Module on ISS

On December 9th, five CubeSats were successfully deployed from the Japanese Experiment Module “Kibo” aboard the International Space Station (ISS). The deployment was part of JAXA’s J-SSOD#30 mission and included DENDEN-01, LignoSat, ONGLAISAT, YODAKA and YOMOGI satellites. Two of these satellites, LignoSat and YOMOGI, have received previous IARU coordination to operate over amateur radio frequencies.

LignoSat was developed by Kyoto University and Sumitomo Forestry Co., Ltd. This CubeSat tests the use of wooden materials in space by measuring strain, temperature, and geomagnetism, along with detecting single event upsets (SEU). Amatuer radio satellite enthusiasts were ready to decode telemetry from the satellite this week, but unfortunately there has been no reported reception of either CW or AX.25 packets on the satellite’s coordinated frequency of 435.820 MHz.

ESA’s Proba-3 Satellites Launch to Create Artificial Solar Eclipses

Two European Space Agency (ESA) satellites launched aboard an Indian rocket on December 5th, beginning a mission to study the Sun’s corona and demonstrate new spaceflight technologies. Called the Proba-3 mission, the two spacecraft will conduct formation flying and create artificial solar eclipses to capture images of the Sun’s outer atmosphere, which is usually hidden by its brightness.

The satellites launched aboard India’s Polar Satellite Launch Vehicle (PSLV) at 5:34 am EST (10:34 UTC) and were placed into an elliptical orbit with a low point of 356 miles (573 kilometers) and a high point of 37,632 miles (60,563 kilometers). Early next year, the Coronagraph satellite, carrying instruments to image the Sun, and the Occulter satellite, equipped with navigation sensors and thrusters, will separate to begin their experiments. The Occulter will position a disk to block the Sun’s surface, casting a shadow on the Coronagraph satellite.

This arrangement allows scientists to create artificial eclipses, blocking sunlight to reveal the solar corona. Natural solar eclipses offer only brief observation windows, and traditional coronagraphs on single spacecraft face challenges like diffraction. Proba-3 addresses these limitations by keeping the two satellites 150 meters apart, enabling clearer imaging of the Sun’s outer atmosphere.

Proba-3 uses advanced navigation technology, including inter-satellite radio links, cameras, and a laser-ranging system. This system maintains millimeter-scale precision between the satellites, allowing them to create artificial eclipses lasting up to six hours. The mission aims to conduct at least 1,000 hours of such observations during its two-year operational phase.

The mission’s scientific goal is to observe a part of the corona that existing instruments cannot study. This region is critical for understanding solar phenomena such as coronal mass ejections and the acceleration of the solar wind, which affect space weather and Earth. The mission will also capture high-frequency images to study plasma waves and jets that may heat the corona and drive the solar wind.

Proba-3 also serves as a test of formation-flying technology. ESA officials hope the techniques demonstrated will be used in future missions, such as Mars Sample Return or space debris removal. “Proba-3 is an important step toward more complex space operations,” said Josef Aschbacher, ESA’s director general. “This mission shows how smaller spacecraft can work together to achieve goals that were not possible before.”

Satellite Shorts From All Over

+ NASA has announced delays to its Artemis moon program, pushing Artemis II, a crewed mission around the moon, to April 2026, with the Artemis III lunar landing planned for mid-2027. NASA Administrator Bill Nelson emphasized that this timeline keeps the U.S. ahead of China’s goal to land on the moon by 2030, highlighting the competitive nature of the space race. The delays follow concerns about the Orion capsule’s heat shield, which cracked during reentry after the uncrewed Artemis I test mission in 2022; Artemis II will proceed with adjustments to the capsule’s trajectory, while future missions will feature an upgraded heat shield. Artemis, initiated under former President Trump’s administration, aims not only to return astronauts to the moon but also to establish lunar bases as a stepping stone for Mars exploration, despite rising costs and development delays. The program’s reliance on SpaceX’s Starship for lunar landings has raised questions about its cost-effectiveness, especially under the incoming Trump administration. Nelson expressed optimism about Artemis’s continuity under NASA’s next administrator, Jared Isaacman, amid ongoing bipartisan and international support for lunar exploration.

+ NASA recently awarded SpaceX a $256.6 million contract to launch Dragonfly, a rotorcraft designed to explore Titan, Saturn’s largest moon, using a nuclear-powered radioisotope thermoelectric generator (RTG). This marks a milestone for SpaceX, as it will be the company’s first time launching a nuclear-powered payload, a domain previously dominated by United Launch Alliance (ULA). The RTG will generate electricity from plutonium-238, chosen because Titan’s dim and cloudy atmosphere precludes the use of solar power. Dragonfly will explore Titan’s surface by hopping between locations using its eight rotors, investigating organic molecules essential to understanding the building blocks of life. Originally set for a 2026 launch, delays due to redesigns, COVID-19 impacts, and supply chain issues have pushed the timeline to July 2028, with costs escalating to $3.35 billion. This mission, one of NASA’s most ambitious robotic endeavors, underscores the transition to new-generation rockets for launching nuclear payloads, with SpaceX’s Falcon Heavy beating ULA’s Vulcan rocket in competitive bidding for this historic mission. (ANS thanks SpaceNews for the above information)

+ The USC Rocket Propulsion Lab (USCRPL) at the University of Southern California has shattered the international altitude record for amateur rocketry with their Aftershock II rocket, reaching an unprecedented 470,000 feet. This achievement surpasses the previous 20-year record of 380,000 feet set by the Civilian Space Exploration Team in 2004, establishing Aftershock II as the first civilian-built rocket to achieve this altitude. Equipped with the most powerful solid-propellant motor ever fired by students and enhanced thermal protection systems, the rocket endured hypersonic speeds with innovative features like titanium-coated fins and a custom paint system. The launch on October 20th in Nevada’s Black Rock Desert also demonstrated advanced avionics and live data integration, enabling precise tracking and recovery. Building on their milestone 2019 launch of Traveler IV, the first student-designed rocket to cross the Kármán line, USCRPL continues to push the boundaries of amateur rocketry with cutting-edge engineering and teamwork. This remarkable achievement highlights the group’s role as a training ground for future leaders in the space industry, inspiring innovation and excellence among aspiring astronautical engineers.

AMSAT OSCAR-7 50th Anniversary – A Testbed for Saving Lives

As we observe AMSAT OSCAR-7’s 50th anniversary as the oldest operating satellite, we should recall what may be its most noteworthy accomplishment.

OSCAR-7 was used to investigate the possibility of locating downed aircraft and disabled sea vessels by using Doppler analysis of signals from emergency location transmitters (ELT’s).

As envisioned by spacecraft engineers from the United States and Russia, the concept was to relay signals from beacon devices, ELT’s or emergency location transmitters, already installed on large and small aircraft and on ships and smaller vessels equipped with EPIRB’s or Emergency Position-Indicating Radiobeacon Stations. These one-way beacon transmitters, originally intended to be received by surface rescue parties, could also be received and transponded by a LEO spacecraft, greatly extending the rescue potential.

The signals could also be Doppler tracked, one-way, by processing the beacon uplink signal on-board the spacecraft. This would allow the spacecraft to find the source beacon’s location immediately. This would allow the emergency beacon to be identified and located and the position stored for immediate downlink at the next available ground station. We know it is hard to remember but this was in an era before the creation of GPS!

Scientists from the Russian COSPAS (Russian acronym for “Space System for the Search of Vessels in Distress) and the U.S. SARSAT (Search and Rescue Satellite) teams simulated ELT’s on amateur radio stations and demonstrated how receiving and relaying ELT transmissions and analyzing Doppler shift as OSCAR-7 passed overhead could accurately locate the emergency beacons.

The tests were highly successful. The COSPAS/SARSAT program went ahead and has been operational since 1982. From that time until 2021, when the program merged with others providing similar capability via LEO, MEO and GEO spacecraft, the program had saved the lives of 57,413 persons in 17,663 separate rescue events, involving downed aircraft and ships at sea.

SpaceX Dragon Fires Thrusters to Boost ISS Orbit for the First Time

For the first time, SpaceX’s Dragon spacecraft successfully raised the orbit of the International Space Station (ISS) by firing its thrusters. The orbital boost marks a significant milestone in Dragon’s capabilities and comes as part of SpaceX’s 31st commercial resupply mission to the ISS. The mission, which launched on November 4, delivered a Dragon cargo vehicle which docked with the station the following day. On November 8, the vehicle conducted an orbit-raising maneuver, stabilizing the ISS’s position in low-Earth orbit.

Orbit-raising maneuvers are routine for the ISS, which requires regular boosts to counteract orbital decay caused by Earth’s gravity. Until now, this task has been handled mainly by Russia’s Soyuz and Progress vehicles, alongside occasional boosts from other spacecraft. With Dragon now performing such maneuvers, the U.S. spacecraft has added a critical capability, especially significant as NASA prepares for the eventual decommissioning of the ISS. The data gathered from today’s maneuver will aid in the development of SpaceX’s future ISS deorbit vehicle, known as the U.S. Deorbit Vehicle, which NASA has contracted to guide the station into the Pacific Ocean upon its retirement.

The reboost began at approximately 12:50 p.m. ET (1750 UTC) and lasted around 12.5 minutes, elevating the station’s orbit slightly. NASA monitored the reboost closely and shared updates on social media platform X, noting that Dragon’s performance in its first orbit-raising task was “a good demonstration” of its growing capabilities. SpaceX intends to apply the maneuver’s data toward the design of the planned U.S. Deorbit Vehicle, scheduled to be used once the ISS reaches the end of its operational lifespan.

This recent success by Dragon is not the first instance of a U.S.-made spacecraft boosting the ISS. In 2022, NASA tested a similar maneuver using a Northrop Grumman Cygnus cargo vehicle. However, the data collected from Dragon’s maneuver holds unique importance, as it directly informs the planning of the ISS’s controlled deorbit mission. The spacecraft, which has been continuously occupied for nearly 25 years, is expected to remain operational until around 2030, when the costs and maintenance demands of the aging structure will likely lead to its retirement.

The ISS’s eventual decommissioning aligns with NASA’s shift towards commercial partnerships in low-Earth orbit. The agency envisions that new, privately operated space stations will replace the ISS as research outposts, enabling NASA to focus its budget on deeper space exploration, including the Artemis Program’s return to the Moon. With the ISS contract awarded to SpaceX, the agency has placed its trust in the private sector to develop the technology needed to safely conclude the station’s mission in a controlled manner.

The success of Dragon’s reboost maneuver also underscores the U.S.’s reduced reliance on Russian spacecraft to maintain ISS operations. Despite global political tensions, notably since Russia’s 2022 invasion of Ukraine, the U.S.-Russian partnership on the ISS has persisted. However, Dragon’s demonstrated ability to perform reboosts offers NASA an alternative if needed. Since Dragon began launching U.S. astronauts in 2020, SpaceX has provided NASA with a reliable launch option from American soil, and now it has proven capable of supporting the station’s orbit, a role essential to the ISS’s long-term stability.

SEAQUE Quantum Tech Arrives at ISS for Groundbreaking Demo

The Space Entanglement and Annealing QUantum Experiment (SEAQUE) has officially arrived at the International Space Station (ISS), delivered aboard NASA’s SpaceX CRS-31 mission. The SpaceX Dragon capsule docked with the ISS on November 4th, carrying over 6,000 pounds of scientific investigations and cargo, including SEAQUE. Planned for installation on the Nanoracks Bishop airlock, SEAQUE represents an important step forward in building a global quantum communications network.

Quantum computers promise computation speeds that are exponentially faster than conventional computers, and distributed quantum sensors may lead to new understandings of Earth and our place in the universe by measuring minute changes in gravity. However, to fully harness these abilities, a dedicated communication network must be established, capable of linking quantum computers and sensors regardless of their location. SEAQUE’s experiment aims to prove the viability of orbiting nodes that can securely transmit and receive quantum data to and from the ground via free-space optical communications.

SEAQUE is among 25 experiments integrated into the Aegis MISSE-20 mission to be installed on the ISS. [Credit: Aegis Aerospace]

A cornerstone of SEAQUE’s mission is to test an integrated source of entangled photons, a critical requirement for secure quantum data transmission. Entangled photons are uniquely interconnected, where measuring one instantly influences the other, regardless of distance. This property enables potential data transmission that is secure and extremely difficult to intercept. Unlike prior quantum experiments that used bulk optics, SEAQUE utilizes a waveguide-based photon source. This innovation is more compact, efficient, and resilient, eliminating the need for manual optical realignment post-launch.

“SEAQUE will demonstrate a new and never-before-flown entanglement source based on integrated optics,” said Paul Kwiat, principal investigator at the University of Illinois Urbana-Champaign. He emphasized that the technology is pivotal for scalable global networks, as manual adjustments would be impractical when managing hundreds of quantum nodes spread across continents. Makan Mohageg, SEAQUE co-investigator from NASA’s Jet Propulsion Laboratory (JPL), reinforced that SEAQUE’s success would pave the way for future, widespread quantum networks.

An added element of SEAQUE’s demonstration involves testing its ability to self-heal from radiation damage, a persistent challenge in space. High-energy particles can impair the detectors that receive quantum signals, causing noise and, eventually, failure. SEAQUE will employ a bright laser to periodically repair such damage using a technique known as annealing. This process has shown success on the ground, “bubbling away” defects and reducing noise to extend detector life.

The SEAQUE mission reflects a truly international effort, including experts and students from the University of Illinois Urbana-Champaign, the University of Waterloo in Ontario, Canada, the National University of Singapore, and commercial partners such as AdvR, Inc., and Nanoracks. Funded by NASA’s Biological and Physical Sciences Division, SEAQUE is expected to drive breakthroughs in secure quantum communications, establishing a foundation for future advancements in long-distance data sharing.

Satellite Shorts From All Over

+ SpaceX is set for its sixth Starship test flight on November 18th, marking the first mission without regulatory delays following FAA approval for both Flights 5 and 6. Flight 6 will be similar to Flight 5, including a suborbital launch and splashdown of the upper stage in the Indian Ocean, with a key difference being an attempted relight of a Raptor engine during coast, revisiting a goal from Flight 3. This test also includes new experiments with the thermal protection system, including sections without heat shield tiles to gather data on ship-catching configurations. SpaceX aims to catch the Super Heavy booster again, making improvements to its propulsion and structural systems after facing near failures and unexpected damage in Flight 5. The launch will depart in the afternoon to achieve a daylight splashdown, while testing higher angles of descent to simulate future landing profiles. Flight 6 will conclude the Block 1 version of Starship, with upgraded features planned for Flight 7, as SpaceX targets a faster launch cadence to support future NASA missions and lunar landings.

+ NASA’s Parker Solar Probe recently completed its seventh and final flyby of Venus, setting it on a course to approach within 3.8 million miles of the sun’s surface—closer than any human-made object in history. This maneuver, crucial for tightening the probe’s orbit, marks a significant step in its mission to study solar mysteries such as the sun’s extremely hot corona. Described by Nour Raouafi as “almost landing on a star” and compared to the 1969 moon landing, the achievement underscores its importance to humanity. The spacecraft’s gravity assists from Venus have not only propelled it closer to the sun but also provided unique data about Venus itself, revealing surface features through its WISPR camera and unexpected details like potential chemical differences. During the most recent flyby, Parker came within 233 miles of Venus’ surface to further study these surface properties. On December 24th, the probe will achieve its closest solar encounter, reaching a speed of 430,000 miles per hour, with mission control anticipating confirmation of its success by December 27th.

+ Arianespace has announced that the second flight of Europe’s Ariane 6 rocket, its first commercial mission, has been rescheduled from December 2024 to no earlier than mid-February 2025. This mission will carry the CSO 3 reconnaissance satellite for the French military and marks the first Ariane 6 launch to be overseen by Arianespace. Initially expected to launch in December following the Vega C rocket’s return to flight, the schedule changed after analysis of an issue during the Ariane 6’s debut in July. The delay stemmed from a temperature measurement anomaly that prevented the upper stage’s auxiliary power unit (APU) from starting, now corrected with a software update. Both the rocket’s core and upper stages are still in production and are set to be transported soon to French Guiana for launch preparation. Arianespace has assured that this delay will not impact future missions, with plans to conduct six Ariane 6 launches in 2025. (ANS thanks SpaceNews for the above information)

+ AST SpaceMobile has recently deployed five massive BlueBird satellites in low Earth orbit, each with a record-breaking 693-square-foot communications array, marking the start of the company’s space-based cellular network. These satellites are brighter than most objects in the night sky, presenting significant challenges for astronomers by obstructing observations. AST aims to establish the first cellular broadband network directly accessible by cell phones, with plans to expand its constellation to over 100 satellites. The rapid increase in large satellites, like those of AST and competitors such as SpaceX and Amazon, has raised concerns about space debris and environmental impact. A group of experts has urged the FCC to reconsider satellite environmental exemptions, fearing an irreversible clutter of space. This surge in satellite launches is not only reshaping communications but also sparking debate on preserving the accessibility of space for scientific exploration.

SpaceX Achieves First Super Heavy Booster Catch in Landmark Starship Flight

SpaceX successfully launched its fifth Starship vehicle on October 13, 2024, marking a milestone with the unprecedented recovery of the Super Heavy booster at the launch site. The mission, dubbed “Flight 5” by SpaceX, lifted off from Starbase in Boca Chica, Texas, at 8:25 a.m. Eastern time. The launch represented a significant step in SpaceX’s long-term goal of achieving rapid reusability for its massive Starship/Super Heavy system.

The key innovation in this test was the planned recovery of the Super Heavy booster, known as Booster 12. After liftoff, the booster performed a series of precise maneuvers to guide itself back to the launch site. The booster was caught by a pair of mechanical arms—often referred to as “chopsticks”—mounted on the launch tower. About seven minutes after liftoff, the arms closed around the top of the booster, just below its grid fins, successfully completing the first-ever “catch” of a returning booster.

SpaceX officials expressed excitement over the achievement, which is critical for the company’s vision of rapid reflight capability. The ability to land the booster directly on the launch pad and prepare it for another flight within days or even hours is a key component of SpaceX’s goal to make space travel more efficient. “I don’t know what to say!” Gwynne Shotwell, SpaceX president and chief operating officer, posted on social media along with a video of the landing, capturing the surprise and enthusiasm following the success.

The mission’s second stage, Starship, flew on a suborbital trajectory, reaching a peak altitude of 212 kilometers before reentering the atmosphere. Unlike the booster, Starship was not intended to be recovered. It performed a controlled splashdown in the Indian Ocean, where it exploded several seconds after touchdown. SpaceX noted improvements to Starship’s heatshield from previous flights, which allowed it to survive reentry in better condition.

The launch came just hours after the Federal Aviation Administration (FAA) granted SpaceX an updated launch license. The revised license, issued after concerns about environmental impacts, allows SpaceX to conduct the next flight—Flight 6—without needing a new authorization. The changes to the license included adjustments to the areas where debris, such as the interstage ring, might land, and an analysis of sonic boom impacts from the returning Super Heavy booster.

The environmental analysis, a requirement for the revised license, determined that there would be no significant impacts from the mission. However, SpaceX is still required to conduct monitoring and take measures to protect the local wildlife surrounding the Boca Chica site. The FAA granted SpaceX the ability to proceed with Flight 6 under the same conditions, but the company must comply with strict regulations, including submitting monitoring data and environmental reports.

NASA’s Europa Clipper Embarks on Epic Journey to Explore Alien Ocean World

NASA’s highly anticipated Europa Clipper mission officially launched on Monday, October 14, 2024, embarking on a journey to explore Jupiter’s moon, Europa. The spacecraft lifted off at 12:06 p.m. Eastern Time aboard a SpaceX Falcon Heavy rocket from Pad 39A at NASA’s Kennedy Space Center in Florida. The launch, described by NASA commentator Derrol Nail as unveiling “the mysteries of an enormous ocean lurking beneath the icy crust of Jupiter’s moon Europa,” marks the beginning of an ambitious astrobiology mission.

The Falcon Heavy’s 27 first-stage Merlin engines roared to life as the rocket ascended, with the two side boosters detaching about three minutes into flight. Separation of the second stage occurred shortly afterward, and Europa Clipper was deployed on its interplanetary trajectory nearly an hour later. Mission control successfully established communication with the probe, confirming that the spacecraft’s solar arrays had deployed as planned, signaling a smooth start to its mission.

Monday’s launch faced a slight delay due to Hurricane Milton, which made landfall on Florida’s Gulf Coast last week, forcing NASA to close the Kennedy Space Center temporarily. Originally scheduled for October 10, the launch was pushed back while teams secured Europa Clipper inside a SpaceX hangar near Pad 39A. This marked the 11th Falcon Heavy launch and only the second time the rocket has been used for an interplanetary mission.

The Europa Clipper mission has faced a long and complex path to the launchpad. Initially, NASA intended to launch the probe using its Space Launch System (SLS), a powerful moon rocket still in development in the mid-2010s. However, repeated delays in the SLS program, along with NASA’s commitment to using the early SLS vehicles for its Artemis moon missions, forced the agency to opt for a commercial alternative. A 2021 budget proposal allowed NASA to choose SpaceX’s Falcon Heavy, though the shift meant the mission’s journey to Jupiter would take nearly six years instead of three.

At the heart of the mission is Europa, a moon thought to harbor a vast subsurface ocean beneath its icy crust. Europa has long intrigued scientists as one of the best places in the solar system to search for signs of life. However, NASA emphasizes that Europa Clipper’s mission is not to find life directly but to assess the moon’s habitability. The spacecraft, carrying a suite of nine science instruments, will study the composition of Europa’s ocean, investigate its icy shell, and look for any signs of recent activity.

After a journey of nearly six years, Europa Clipper is expected to enter orbit around Jupiter in April 2030, where it will begin an extended series of flybys of Europa. Over the course of its mission, the probe will make close passes to the moon, gathering data that could inform future missions, including a potential lander. The mission is set to conclude in 2034, with NASA planning to crash Europa Clipper into Jupiter’s moon Ganymede to avoid contaminating Europa’s pristine environment.

European Spacecraft Launches to Investigate NASA’s Asteroid Defense Test

A European spacecraft, along with two CubeSats, has launched to investigate the aftermath of NASA’s first planetary defense mission, known as DART. The European Space Agency’s Hera mission took off on October 7, 2024, aboard a SpaceX Falcon 9 rocket from NASA’s Kennedy Space Center. The mission aims to study the consequences of NASA’s 2022 mission, which deliberately crashed a spacecraft into the asteroid Dimorphos, changing its orbit.

The Hera mission, slated to arrive at Dimorphos and its larger companion asteroid Didymos in 2026, is expected to offer a detailed “crash scene investigation,” according to European scientists. NASA’s DART mission had tested whether a kinetic impact, or crashing a spacecraft into a celestial body at high speeds, could alter the object’s trajectory. While neither asteroid poses a threat to Earth, Dimorphos was chosen for the experiment because of its size, which is comparable to asteroids that could potentially be hazardous in the future.

Observations following DART’s collision with Dimorphos in September 2022 revealed that the spacecraft succeeded in altering the asteroid’s orbital period by about 32 to 33 minutes. However, many questions remain unanswered, such as whether the impact merely left a crater or completely reshaped Dimorphos. The Hera mission is tasked with solving these mysteries by providing detailed data on the structure and composition of both asteroids, which will further refine planetary defense strategies.

Hera is scheduled to reach the Didymos system in late 2026, after a mid-March 2025 flyby of Mars to gain the necessary momentum. During the flyby, Hera will test its suite of instruments and observe Mars’ moon Deimos, capturing data that will support Japan’s upcoming Martian Moons eXploration mission. Once Hera arrives at the Didymos system, it will spend six weeks conducting surveys of both asteroids, using a variety of instruments to study their shapes, masses, and thermal properties.

Hera will also release two CubeSats, Juventas and Milani, to conduct more specific investigations. Juventas will use radar to probe the interior of Dimorphos, while Milani will study the mineral composition and dust environment of both asteroids. These CubeSats will communicate their findings to Hera and relay the data back to Earth, providing scientists with unprecedented insights into the double-asteroid system.

Ultimately, the Hera mission could end with experimental landings on either Didymos or Dimorphos, further extending its ability to study the asteroids up close. Scientists hope the data collected will deepen understanding of how asteroid deflection technology can be used to protect Earth from future threats. As Patrick Michel, principal investigator of the Hera mission, noted, while DART was a success, Hera will complete the story by offering crucial details that could inspire future planetary defense initiatives.

+ On October 4, United Launch Alliance (ULA) successfully launched its second Vulcan rocket, despite one of the solid-propellant strap-on boosters encountering an anomaly 37 seconds after liftoff. The booster emitted sparks and debris, but the rocket continued its ascent and reached orbit. This mission is part of the certification process for the Vulcan rocket, which will soon carry national security payloads for the U.S. Space Force and the National Reconnaissance Office (NRO). ULA included a dummy payload and technology experiments to gather data and validate the rocket’s performance. The booster issue is under investigation, but the key mission objectives were met, according to ULA CEO Tory Bruno. The Vulcan rocket, powered by Blue Origin’s BE-4 engines, will replace ULA’s Delta 4 and Atlas 5 rockets, positioning the company for future success in the competitive space market. (ANS thanks Spaceflight Now for the above information)

+ Four astronauts aboard the International Space Station (ISS) are awaiting their return as mission managers monitor unfavorable weather conditions off the coast of Florida. The Crew-8 mission, which includes NASA astronauts Matthew Dominick, Mike Barratt, and Jeanette Epps, along with Roscosmos cosmonaut Alexander Grebenkin, is nearing its conclusion after seven months in space. While they prepare for their journey home, the crew spent the week relaxing and engaging in pre-departure activities. A weather briefing occurred on Wednesday, October 16, at 11 a.m. EDT, assessing conditions for their splashdown. Mission managers are now targeting a new undocking time of no earlier than 3:05 a.m. EDT on Sunday, October 20. (ANS thanks SciTechDaily for the above information)

+ The FAA authorized SpaceX to resume Falcon 9 flights on October 11, following a suspension caused by an upper stage anomaly during the Crew-9 mission on September 28. The anomaly occurred when the Merlin engine burned 500 milliseconds longer than planned, resulting in reentry outside its designated zone. SpaceX conducted an investigation, and the FAA approved their corrective actions, though neither disclosed specific details of the findings. A special exception had been made for the European Space Agency’s Hera mission on October 7, as it posed no public safety risk. With the issue resolved, Falcon 9 operations fully resumed on October 15. SpaceX marked its return with a double Starlink mission, launching from both Vandenberg and Cape Canaveral on the same day. (ANS thanks SpaceNews for the above information)

+ Following Hurricane Helene, T-Mobile and Starlink activated their satellite texting service in preparation for Hurricane Milton to ensure Florida residents could stay connected despite potential cellular outages. After the Federal Communications Commission granted emergency approval, the service enabled T-Mobile users to send and receive basic texts, including 911 messages, even if the network went down. Starlink’s Direct to Cell satellites were also employed to send emergency alerts to all phones and carriers in the affected areas. Users could determine if their phone connected to a Starlink satellite by the presence of one to two bars of signal and the network name displaying “T-Mobile SpaceX.” The satellite service worked best outdoors or near windows, although users sometimes had to retry sending messages if they didn’t go through on the first attempt. SpaceX has also delivered over 10,000 Starlink kits in response to Hurricane Helene, as part of ongoing recovery efforts. (ANS thanks Engadget for the above information)
