Following the standard ascent profile for Meteor satellites, the launch trajectory headed northwest over eastern Russia, reaching a near-polar orbit with an inclination of approximately 98.57 degrees. The fairing protecting the payload separated during the second stage operation, with subsequent stage separations carefully planned for safe impact zones in the Amur Region and the Sakha Republic.

The Fregat upper stage took charge of the final payload deployment, executing precise maneuvers over the Arctic and Antarctica. Approximately 59 minutes and 46 seconds after liftoff, the Meteor-M2-4 satellite was successfully released, accomplishing its primary mission. The Fregat then proceeded to deploy the secondary payloads into their designated orbits.

The Russian Meteor M2-4 satellite commenced transmitting weather images within the first day in orbit. Known for their accessibility to amateur users, Meteor M satellites operate around 137 MHz, making them receivable with a RTL-SDR dongle and suitable satellite antennas. The satellite also transmits in the L-band, enabling reception with a 60cm or larger dish and motorized or hand tracking. Unlike previous satellites in the series, M2-4 experienced a smooth launch and deployment, with reports indicating excellent signal strength and clear image reception in both VHF and L-band frequencies. Two-Line Elements (TLE’s) and the SatDump decoding software (https://github.com/SatDump/SatDump) have been updated to support Meteor M2-4, simplifying access for enthusiasts through Github updates.

Space historian Jonathan McDowell shared valuable insights into the flight, detailing each Fregat maneuver and its impact on the satellite cluster. While the majority of the secondary payloads adhered to the expected orbits, anomalies in the deployment of some SITRO satellites prompted further investigation. The launch of Meteor-M2-4 and its accompanying payloads stands as a noteworthy accomplishment for Russia’s space program, contributing significantly to global endeavors in weather monitoring, Earth observation, and satellite technology development.

+ The inaugural components for Europe’s new Ariane 6 rocket have reached the port of Pariacabo in Kourou, French Guiana, transported by the container ship, Canopée. Manufactured across Europe, the central core arrived on Canopée, which uses sails to reduce emissions and save up to 30% on fuel during its 10-day, 7,000 km journey. The rocket’s stages were produced in various European locations, with the main engine and stage integrated in Les Mureaux, France, and the upper stage and insulation in Bremen, Germany. Following transport, the components were offloaded and taken to the Ariane 6 assembly building, a few kilometers away, where they will undergo integration before liftoff. The boosters, already at Europe’s Spaceport, are P120C solid propulsion boosters similar to those used for the Vega-C rocket. The central core will be assembled horizontally and then transported to the launchpad, where it will be erected, followed by the addition of boosters and the upper stage, with the goal of a summer launch for Flight Model-1.

ESA Satellite Communications Group Explores Future Amateur Satellite Payload

Frank Zeppenfeldt, PDØAP, representing the European Space Agency (ESA), provided key insights during a presentation on February 4th at the FOSDEM 2024 conference held in Brussels, Belgium. The discussion centered around ESA’s initiative to collaborate with the amateur satellite community in defining a prospective payload for Medium Earth Orbit (MEO) or Geostationary Orbit (GEO). The ESA’s involvement aims to build upon the success of the QO-100 payload in geostationary orbit, fostering innovation and technological advancements.

During the FOSDEM conference, the ESA Satellite Communications Group outlined preliminary ideas, stressing the significance of engaging with the Software-Defined Radio (SDR) community. The primary objectives include consolidating requirements, exploring diverse payload options, addressing user segments, and thoroughly examining financing, procurement, and operational scenarios for a potential MEO/GEO amateur payload.

JS1YMG: Decoding the First Moon-Based Ham Radio Station’s Telemetry Signals

JQ1ZVI (JAXA Ham Radio Club, JHRC) recently obtained a radio station license from Japan for the lunar rover LEV-1, designated JS1YMG, marking a historic moment as the first amateur radio station on the moon. This milestone achievement follows Japan’s SLIM lunar mission, which saw the deployment of two lunar excursion vehicles, LEV-1 and LEV-2.

LEV-1, designed for hopping mobility, features direct-to-Earth communication capabilities via UHF band antennas from the MINERVA and OMOTENASHI projects. Equipped with two wide-angle visible light cameras, LEV-1 conducts lunar exploration while carrying essential science payloads, including a thermometer, radiation monitor, and inclinometer, providing valuable insights into lunar conditions and terrain. It actively receives data from its companion rover LEV-2, and this information is transmitted to Earth using its 1 Watt UHF circular polarization antenna, employing Morse code on a IARU coordinated frequency of 437.410 MHz.

Decoding efforts by Daniel Estévez, EA4GPZ, and others have shed light on the telemetry data transmitted by LEV-1. Utilizing captures from the 25-meter radio telescope at Dwingeloo in the Netherlands, Estévez identified the telemetry format as PCM/PSK/PM with a symbol rate of 64 baud and a 2048 kHz subcarrier. The residual carrier is modulated in amplitude with Morse code, introducing an unusual element to the signal. Despite challenges posed by amplitude shift keying in the signal, a phase-locked loop (PLL) has proven effective in tracking the phase of the residual carrier.

Estévez’s decoding journey involved unraveling the CCSDS coding, a task that posed initial challenges. While the IARU coordination sheet hinted at bitrates and coding specifics, the signal’s unique characteristics required a thorough investigation. The BCJR decoder, a tool used successfully in previous decoding efforts, validated the presence of convolutional coding. The output provided log-likelihood ratios, offering confidence in the correctness of the convolutional code. Further investigations led to the identification of the syncword 0xFAF320, a crucial element in understanding the structure of the transmitted frames.

One intriguing aspect of the decoded data is the Morse code modulating the residual carrier in amplitude. Despite initial confusion caused by an inverted amplitude representation, subsequent analysis revealed recognizable Morse code sequences. The meaning behind these Morse code transmissions remains a mystery, inviting collaboration from the broader radio amateur community and the LEV-1 team. As decoding efforts continue, the telemetry data’s contents remain unknown, emphasizing the need for more documentation from the LEV-1 team. The spacecraft’s utilization of the amateur satellite service and its completion of the IARU coordination process suggest that technical documentation may become publicly available in the future.

More details on the ongoing efforts to decode LEV-1’s amateur radio transmissions can be found at Daniel Estévez’s website at https://destevez.net/2024/01/trying-to-decode-lev-1/.

This achievement in establishing the first amateur radio station on the Moon opens up new possibilities for lunar communications and amateur radio enthusiasts worldwide. The collaborative efforts of radio amateurs contribute significantly pave the way for future advancements in space communication technologies.

ARISS Announces NASA Astronaut Tony England WØORE as Speaker for 40th Anniversary Celebration

Amateur Radio on the International Space Station (ARISS) has announced NASA astronaut Tony England WØORE as the latest addition to the esteemed lineup for the “40th Anniversary Conference: Celebrating the Positive Impact of Amateur Radio on Human Spaceflight” event at Kennedy Space Center, set to occur from February 22 to 24, 2024. Tony England will be the third astronaut speaker at the event, in addition to Richard Garriott, W5KQW, and Bill McArthur, KC5ACR.

Tony England, the second astronaut to make ham radio contacts from space and the first to engage in Slow-Scan Television (SSTV) transmissions from orbit, brings a wealth of experience to the event. Selected as a scientist-astronaut by NASA in August 1967 at the age of 25, he holds the distinction of being the youngest candidate selected up to that time. England completed rigorous academic and flight training, earning his wings with distinguished honors in April 1969.

His contributions to space missions include serving as a support crewman for Apollo 13 and 16 flights. Notably, England played a crucial role during the Apollo 16 mission as the Extra-Vehicular Activity (EVA) Capcom, providing instructions to astronauts exploring the lunar surface. His expertise also extended to the development and communication of instructions for constructing lithium hydroxide canisters on Apollo 13.

In the summer of 1985, England was a part of the STS-51-F mission, which carried a seven-man crew and Spacelab-2. This mission marked the first pallet-only Spacelab mission and the debut of the Spacelab Instrument Pointing System (IPS). England’s responsibilities included activating and operating Spacelab systems, operating the IPS and the Remote Manipulator System, assisting with experiment operations, and being prepared for a contingency Extra-Vehicular Activity if needed. The mission successfully completed 126 orbits of the Earth.

Richard Garriott W5KQW, a second-generation space traveler, ARISS veteran, and entrepreneur, has been announced as the keynote conference speaker. The 40th Anniversary Celebration event will also feature other distinguished speakers, including Bill McArthur, KC5ACR, a NASA Astronaut with experience on the Shuttle, Mir, and the International Space Station (ISS), and Mike Kincaid, NASA Associate Administrator for the Office of STEM (Science, Technology, Engineering, and Mathematics) Engagement.

The 40th Anniversary Conference is scheduled to occur at the Center for Space Education, located next to the NASA Kennedy Space Center Visitor’s Center in Florida. This event is not only a reflection on past achievements but also a platform to showcase the exciting potential of amateur radio in future human spaceflight endeavors. The discussions will encompass potential operations on commercial space stations, lunar exploration, and even ventures toward Mars. The celebration is poised to offer a retrospective of notable achievements and delve into the evolving role of amateur radio in shaping the trajectory of human space exploration.

Vulcan Centaur Triumphs in Maiden Voyage, Peregrine Lander Faces Lunar Setback

Vulcan Centaur, a new heavy-lift booster developed by United Launch Alliance (ULA), successfully completed its inaugural flight. However, the mission took a bittersweet turn as the Peregrine lander, set to be the first American spacecraft to touch down on the lunar surface since 1972, faced significant challenges shortly after separation from the Centaur upper stage.

United Launch Alliance (ULA), known for its 100% mission success rate with the Atlas V and Delta IV rockets since 2006, faced a changing commercial launch landscape by the early 2010s. SpaceX’s Falcon 9 was offering cheaper alternatives, prompting ULA to develop a more cost-effective and agile solution. The result was the Vulcan Centaur, a combination of a new first stage and an evolved Centaur III second stage.

Originally planned for launch in 2019, the Vulcan program encountered delays, primarily due to the slower-than-expected development of the BE-4 engines by Blue Origin. Despite setbacks and an explosion during Centaur upper stage testing in March 2023, the January 8th launch marked a significant achievement for ULA. Powered by liquid methane and liquid oxygen (methalox), the Vulcan Centaur demonstrated successful flight, a milestone for American orbital rockets using this propellant combination.

ULA’s CEO Tory Bruno expressed satisfaction with the launch, labeling it one of the smoothest in his career. The successful flight positions ULA to compete more effectively in the evolving space launch market.

While the Vulcan Centaur celebrated success, the fate of the Peregrine lander took a dramatic turn. Developed by Astrobotic Technology, Peregrine had ambitious plans, including bringing memorials, time capsules, scientific instruments, the Iris rover, and small robots to the lunar surface.

Initial reports suggested a promising start when Peregrine separated from the Centaur and established communications with ground control. However, soon after enabling its propulsion systems, the lander faced difficulties maintaining its orientation, leading to a rapid depletion of its batteries. Astrobotic attempted to stabilize the craft, but it was confirmed that a leak was destabilizing Peregrine and draining essential propellants needed for a lunar landing.

Astrobotic ruled out any possibility of a lunar landing, and as of the latest update, the team faces the challenge of navigating Peregrine as close to the Moon as possible before its propellant runs out. With communication uncertain, the fate of the lander remains uncertain.

January 8th showcased both success and setbacks in space exploration. The Vulcan Centaur’s triumphant launch demonstrated progress in rocket technology, while the Peregrine’s struggles highlighted the inherent difficulties of space missions. As technology advances, the moon remains an enticing destination, with the upcoming Nova-C lander’s launch in February offering renewed hope for successful lunar exploration. The events of this day remind us that despite the challenges, the pursuit of space exploration continues unabated.

ARISS Marks 40th Anniversary of STS-9 with Special Slow Scan Television Event

In a collaborative effort spanning ARISS teams worldwide, a special Slow Scan Television (SSTV) event is currently underway to mark the 40th Anniversary of NASA Space Shuttle mission STS-9. SSTV transmissions from the International Space Station (ISS) are being broadcast on 145.800 MHz using the PD120 format. The scheduled times for the event are from December 16 at 10:15 UTC | 5:15 AM ET through December 19 around 1800 UTC | 1:00 PM ET.

On November 28, 1983, the Space Shuttle Columbia carried Owen Garriott, W5LFL (SK), into orbit. He was equipped with a specially customized Motorola MX-340 two-meter handheld radio and an antenna attached to the shuttle’s window. The first amateur radio contact from space took place shortly before crossing the west coast on December 1, 1983, when Columbia executed a roll maneuver exposing the antenna toward Earth. W5LFL began calling CQ, and at 02:38 UTC, Lance Collister, WA1JXN, in Frenchtown, MT, answered the call, marking the first amateur radio QSO with a human in space.

A flurry of QSOs followed over the next several days before Columbia returned to Earth on December 8th. Notable amateur operators in the log included Senator Barry Goldwater, K7UGA, and King Hussein of Jordan, JY1. Slow Scan Television has also been an integral part of Amateur Radio in Human Spaceflight since its early days, with Tony England, WØORE, paving the way by sending ten images via Slow Scan Television on Space Shuttle Challenger mission STS-51F in the summer of 1985.

Answers to your Frequently Asked Questions (FAQ) about this ISS Slow Scan Television Event, such as how to decode SSTV images and track the ISS, can be found at https://www.spaceflightsoftware.com/ARISS_SSTV/faq.php. You can apply for the ARISS SSTV Award by uploading your decoded image and completing the Application Form using the information provided at https://ariss.pzk.org.pl/sstv. Don’t forget that you can receive a QSL Card from the International Space Station by receiving and decoding a SSTV image. More information about how to obtain a QSL Card can be found at https://www.ariss.org/qsl-cards.html.

HADES-D Satellite: Successful Telecommand Response and FM Repeater Tests Ongoing

The HADES-D satellite, launched aboard SpaceX’s Transporter-9 (TR-9) mission on November 11, 2023, has successfully completed a month in orbit. AMSAT-EA reports that, following its separation from the ION SCV-013 Orbital Transfer Vehicle two weeks ago, HADES-D is responding well to telecommands from the ground control station.

Current tests on the FM voice repeater show promising results, demonstrating its effectiveness. However, adjustments to the squelch level are under consideration due to the current configuration requiring increased power for activation. HADES-D’s health status has been confirmed through telemetry, CW, and FM voice beacon receptions from various Earth locations.

Telemetry signals in FSK, CW, and FM voice beacon, operating at 436.666 MHz downlink, transmit to Earth at 0.25 Watts. Demodulation and decoding software for satellite telemetry are available on AMSAT-EA’s website under the Project tab (https://www.amsat-ea.org/proyectos). The FM repeater, with a 40mW power output, may require a robust antenna for optimal receive performance.

Developed alongside the URESAT Antonio de Nebrija, both utilizing the pocketQubes 1.5P platform, HADES-D features advanced solar panels and increased processing capacity. These advancements enable the satellite to transmit telemetry and repeat signals at higher speeds. The incorporation of an FM transponder for voice communications also allows for message retransmission in FSK. Efforts are ongoing to confirm the final Two-Line Elements for streamlined operations.

WRC-23 Reaches Acceptable Conclusion on 23-Centimeter Issue

The International Telecommunication Union (ITU) World Radiocommunication Conference 2023 (WRC-23) continues through December 15, 2023, in Dubai, United Arab Emirates (UAE).

The International Amateur Radio Union (IARU)’s primary effort focused on Agenda Item 9.1 topic b to address amateur use of the 23-centimeter band and co-frequency use by several radionavigation satellite service (RNSS) systems in the 1240 – 1300 MHz band.

IARU’s work that began four years ago with a preparatory study in the ITU Radiocommunication Sector (ITU-R) to address this agenda item has finally come to a close. Our concerted engagement in the ITU-R working parties, study groups, and WRC preparatory meetings ensured that the amateur services were properly represented during the development of two published ITU-R reports: M.2513 and M.2532. An ITU-R Recommendation, M.2164, followed these, which formed the basis for the discussions at WRC-23.

During the WRC-23 deliberations, strong positions were expressed by all parties involved.

The result is a well-supported compromise for a footnote in the Radio Regulations regarding amateur and amateur satellite service operation in the 1240 -1300 MHz range. The footnote reminds administrations and amateurs of the need to protect the primary RNSS from interference, and it provides guidance for administrations to allow both services to continue to operate in this portion of the spectrum.

Administrations are the bodies that govern amateur radio in their respective countries, such as the Federal Communications Commission (FCC) in the United States.

The Conference Plenary compromise was formally adopted on December 8 and is not subject to further consideration during the final week of WRC-23. The IARU team continues its work on other WRC issues, including developing agendas for future conferences.

IARU President Tim Ellam, VE6SH, noted, “This is a very good result for the amateur services. The decision reached at WRC-23 on this agenda item makes no change to the table of allocations nor incorporates by reference M.2164 into the Radio Regulations. The addition of a footnote that provides guidance to administrations in the event of interference to the RNSS is a good regulatory outcome for amateurs and the primary users of this band.”

The WRC also agreed to suppress Resolution 774, which closes the issue and satisfies the agenda item. Read more in ARRL News at https://www.arrl.org/news/wrc-23-reaches-acceptable-conclusion-on-23-centimeter-issue

How the 18th Space Defense Squadron Averts Catastrophe at 17,000 Miles Per Hour

In the vast expanse of space, where countless manmade objects hurtle through Low Earth Orbit at speeds exceeding 17,000 miles per hour, a dedicated group of guardians stands watch to prevent potential collisions that could disrupt crucial communication, navigation, and scientific satellites. The 18th Space Defense Squadron (SDS), part of the Space Force, operates from its headquarters at Vandenberg Space Force Base, California, employing advanced technology and surveillance systems to track and identify potential collision risks in real-time.

The 18th SDS, often referred to as the “lighthouse of space,” utilizes the U.S. Space Surveillance Network (SSN) to monitor over 45,000 objects in Earth’s orbit. Ground-based sensors, including the Ground-Based Electro-Optical Deep Space Surveillance System, capture rapid digital photos of the night sky, revealing satellites as tiny streaks. Computers analyze these streaks to calculate the satellites’ positions, providing vital data for collision risk assessments, as explained in a recent press release from the Space Operations Command.

Key components of the SSN include ground-based radar systems such as the AN/FPS-85 and AN/FYS-3 Phased Array Radars, capable of tracking hundreds of targets simultaneously. The ‘Space Fence,’ located in the Marshall Islands, employs an array system that broadcasts constant bands of energy, tracking objects passing through its coverage. On-orbit platforms like the Space-Based Space Surveillance satellite ensure year-round tracking above earthly obstructions like weather and daylight.

Maintaining an ever-growing catalog of space objects on Space-Track.org, the 18th SDS collaborates with its counterpart, the 19th SDS, to predict satellite trajectories and avert potential collisions. In the crowded expanse of low Earth orbit, the squadron remains vigilant, recognizing the heightened risk posed by unexpected satellite fragments that could lead to disastrous collisions.

Space Operations Command (SpOC) recently outlined four categories of fragmentation events: anomalous debris-causing events, breakup events, collisions, and mission-related events. Anomalous events occur due to factors like corrosion or fatigue, leading to slow-speed fragment dispersal. Breakup events, generating large amounts of rapidly spreading debris, can be unintentional or intentional, as seen in anti-satellite missile tests. Collisions, exemplified by the 2009 incident involving a Russian military satellite and a commercial Iridium satellite, prompt heightened awareness and response. Mission-related events involve the fragmentation of payloads or unintentional separation of non-payload components.

Members of the 18th SDS remain vigilant for changes in orbital parameters, indicators of potential satellite stress or gas release, which could precede fragmentation events. Specialized software assists in tracking satellite trajectories and determining the origin and trajectory of debris in case of fragmentation. Timely warnings to affected satellite operators enable them to make necessary adjustments, minimizing collision risks.

Despite the 18th SDS’s capabilities, over a million objects under 10 cm remain untrackable but pose significant collision threats. The act of maneuvering to avoid collisions consumes satellite fuel and shortens their lifespan. Recognizing the limitations, a recent call by the research group RAND advocates for an international space traffic management system (STM) to enhance coordination and communication among satellite operators.

The current state of managing space objects is described by RAND researchers as “informal, ad hoc, and often ill-coordinated,” approaching a tipping point. Urging proactive governance structures, the researchers emphasize the need for the space community to build systems ensuring the safety and sustainability of critical space assets, services, and activities before a crisis necessitates action.

CubeSat Technology and 3D Printing Combine for Emergency Broadband in Disaster Zones

Researchers from the Centre Tecnològic de Telecomunicacions de Catalunya (CTTC), the University of Luxembourg, and the Universitat Oberta de Catalunya (UOC) have developed a nanosatellite technology aimed at delivering swift emergency broadband connectivity to disaster-stricken regions. This innovative solution combines CubeSat technology with 3D printing, allowing for rapid deployment to enhance communication for emergency services in complex situations.

Professor Carlos Monzo Sánchez of the Universitat Oberta de Catalunya emphasizes the project’s significance, stating, “Our project provides a solution that means a communications network to provide help in emergency situations can be established quickly.” The core technology is the CubeSat standard for nanosatellites, known for their cost-effectiveness and small size, manufactured on a 3D printer in just 90 minutes.

The CubeSats are then elevated above disaster zones using balloons, utilizing LoRa (low-power long-range radio) communication with the ground. Raúl Parada, a researcher at CTTC and the paper’s first author, explains, “Our solution enables communication over long distances and provides a scalable system for a large number of users that is reusable anywhere and at any time.”

The team’s prototypes leverage the Semtech SX1278 LoRa transceiver, connected to a simple metal ruler antenna. The 1U CubeSat, housing the transceiver, is equipped with a sensor package comprising a Bosch Sensortec BME280 environmental sensor, a TDK InvenSense MPU-9250 inertial measurement unit (IMU), a Hanwei MQ-135 air quality sensor, and a Roithner LaserTechnik GUVA-S12SD ultraviolet light sensor. These sensors are linked to an Arduino Nano microcontroller, with a GPS receiver added later to facilitate satellite recovery.

Emphasizing the practicality of their design, Monzo explains, “Our solution is designed to provide a rapid service in complex scenarios, and as such, we have prioritized its ease of deployment over its use as a telecommunications solution in normal situations.” The researchers aim to refine the infrastructure further, focusing on minimizing deployment times and ensuring adaptability to a wide range of situations.

The team’s work has been published in the journal Aerospace under open-access terms, marking a significant stride in leveraging technology to enhance emergency response capabilities in disaster-stricken areas.

+ AO-73 (FUNcube-1), managed by AMSAT-UK and AMSAT-NL, has reactivated its transponder after a meticulous year of battery management. Launched a decade ago, the satellite faced challenges with its battery struggling to reach the nominal 8.3V charge. Recent efforts, including strategic transmitter shutdowns during eclipse periods, have improved the situation. The battery voltage now varies between 8.13V in sunlight and 7.8V at the end of an eclipse, a significant improvement. AO-73 is currently transmitting low-power BPSK telemetry on 145.935MHz, featuring an inverting mode U/V transponder uplink ranging from 435.130 to 435.150 MHz, with a downlink set at 145.970 to 145.950 MHz. The satellite maintains a high spin rate of approximately 30 rpm, requiring manual tuning for the 70 cm input due to the receiver’s temperature drift. This development reopens exciting opportunities for radio operators interested in exploring AO-73’s capabilities after its temporary hiatus.

+ NASA’s Voyager 1 probe, now in interstellar space, is experiencing a communication glitch, preventing the transmission of scientific or systems data. The 46-year-old spacecraft can receive commands, but its flight data system (FDS) is no longer communicating as expected with the telecommunications unit (TMU). The FDS compiles data into a package for transmission, but it’s currently stuck in a repeating pattern of ones and zeros. Voyager’s engineering team is investigating, but a solution may take weeks. The spacecraft’s age and technology from the 1970s present unique challenges, and previous malfunctions required creative software workarounds. Despite past issues, finding solutions for Voyager’s challenges is a slow process, involving consultation of decades-old documents.

+ Blue Origin is set to resume New Shepard suborbital launches no earlier than December 18th, marking the vehicle’s first potential flight in over 15 months. The uncrewed mission, NS-24, will follow a mishap in September 2022 when a structural failure in the BE-3PM engine led to a capsule landing safely while the propulsion module crashed. The Federal Aviation Administration closed its investigation in September 2023, outlining 21 corrective actions for Blue Origin, including technical modifications and organizational changes. The delay in resuming flights prompted speculation about the company’s priorities, but it has since won a NASA contract for a lunar lander, introduced an orbital transfer vehicle, and progressed with the New Glenn orbital launch vehicle and Orbital Reef space station projects. During this hiatus, Virgin Galactic began commercial service with its SpaceShipTwo, VSS Unity, but announced plans to shift to quarterly flights in 2024 and eventually halt operations to focus on new suborbital vehicles.

+ NASA astronaut Frank Rubio grew tomatoes in space using hydroponic techniques to demonstrate space agricultural methods on the International Space Station (ISS). After harvesting one of the first tomatoes grown in space, Rubio misplaced it during a public event with school kids, sparking a humorous search on the ISS. In the microgravity environment, anything unanchored can float away, and despite spending hours searching, Rubio never found the tomato. The mystery ended when the remaining ISS crew announced they had located the tomato, clearing Rubio of suspicions that he had eaten it. Rubio’s historic mission on the ISS, lasting over a year, set a record for the longest a US astronaut has spent in microgravity, initially planned for six months.
