ARISS Announces 40th Anniversary Conference at NASA Kennedy Space Center

In recognition of the positive impact of amateur radio on human spaceflight, an exciting celebration is on the horizon. Space enthusiasts, astronauts, educators, and amateur radio operators are coming together to commemorate the 40th Anniversary of a groundbreaking event. This pivotal moment occurred when Astronaut Owen Garriott, W5LFL, pioneered amateur radio communication from space during his mission on the STS-9 Space Shuttle Columbia flight, spanning from November 28 to December 8, 1983.

Astronaut Garriott, during his free time on the STS-9 mission, became the first person in space to communicate with amateur radio operators on the ground. Moreover, his radio signals were the first ever to be directly heard from space by the public, using nothing more than simple FM receivers and scanners. This milestone forever changed astronaut communication, opening up interaction with amateur radio operators and the public, who previously had limited access to speak with spacefarers.

Over the past four decades, Garriott’s pioneering mission has paved the way for countless interactions between astronauts and Earthlings through the medium of amateur radio, on the Space Shuttle, Mir space station, and the International Space Station. Over a million people on Earth have directly participated in these astronaut radio contact engagements, with a particular emphasis on educational youth contacts. This initiative, coupled with pre-contact education programs, has ignited the spark of curiosity and interest in Science, Technology, Engineering, and Math (STEM) among youth worldwide.

As the 40th anniversary of human spaceflight amateur radio approaches, the ARISS (Amateur Radio on the International Space Station) team is inviting volunteer teams, astronauts, space agency officials, educators, and space and amateur radio enthusiasts to join them in commemorating and celebrating this inspirational journey. The event, titled the “40th Anniversary Celebration of the Positive Impact of Amateur Radio on Human Spaceflight” is scheduled to take place from February 22 to 24, 2024, at the Center for Space Education: Astronauts Memorial Foundation, located adjacent to the NASA Kennedy Space Center Visitors Center in Florida.

The conference promises an array of engaging activities, including tours of the NASA Kennedy Space Center Visitors Center, exhibits on human spaceflight amateur radio, networking sessions, STEM education demonstrations, and two days filled with astronaut panel sessions. Attendees can also look forward to presentations by STEM career alumni and recollections shared by educators and volunteer team alumni who supported hardware development, flight operations, and youth STEM engagement for the Shuttle, Mir, and ISS missions.

In a special request, the organizers of the event are seeking the stories of students who participated in the SAREX (Shuttle/Space Amateur Radio Experiment), Mir, and ARISS programs over the last 40 years and have since pursued careers in STEM. These students or those who know them are encouraged to get in touch with the organizers through in-person participation, video submissions, emails, or letters. Additionally, educator testimonials regarding the impact of these programs in schools are welcomed.

Amateur Radio on the International Space Station (ARISS) is a collaborative initiative between international amateur radio societies and space agencies supporting the International Space Station (ISS). In the United States, sponsors include the American Radio Relay League (ARRL), Amateur Radio Digital Communications (ARDC), Radio Amateur Satellite Corporation (AMSAT), NASA’s Space Communications and Navigation program (SCaN), and the ISS National Lab—Space Station Explorers. The primary goal of ARISS is to foster exploration of science, technology, engineering, the arts, and mathematics topics through organized scheduled contacts between ISS crew members and students via amateur radio. These contacts are accompanied by hands-on learning activities related to space, space technologies, and amateur radio.

For registration and special event pricing at local hotels for the 40th Anniversary Conference, visit the event website at https://www.ariss.org and select the “40th Anniversary” tab.

Upcoming International Space Station Slow Scan TV Transmission Test

The International Space Station (ISS) is set to conduct a Slow Scan Television (SSTV) transmission test between October 27 and November 1, 2023. The test will serve to verify the performance of replacement SSTV equipment onboard the station. However, the test will be divided into two windows due to an Extra-Vehicular Activity (EVA) taking place during that time frame.

The first window for SSTV transmissions will open on Friday, October 27, at 12:15 UTC and will run until Sunday, October 29, at 18:50 UTC. The second window will begin on Tuesday, October 31, at 10:05 UTC and conclude on Wednesday, November 1, at 18:10 UTC. During these windows, the SSTV transmissions will take place on 145.800 MHz using the PD120 format.

It’s important to note that, similar to the earlier October test, the SSTV transmissions may not be active at all times within the specified windows. Therefore, enthusiasts and radio operators eager to capture these images should monitor the frequencies and times closely.

The ARISS (Amateur Radio on the International Space Station) SSTV gallery will be available for individuals to share the images they receive. The gallery can be accessed at https://www.spaceflightsoftware.com/ARISS_SSTV/index.php. For more information on the SSTV images transmitted from the ISS, you can visit the Gallery Website. This website will showcase some of the best SSTV images received during the test period.

No ARISS SSTV awards will be given for this event through the https://ariss.pzk.org.pl/sstv/ website. Stay tuned for further updates and don’t miss the chance to participate in this unique opportunity to capture images from space. For official updates and notifications related to the SSTV test, individuals are encouraged to follow ARISS on Twitter (@ARISS_Intl).

ISRO’s Gaganyaan Successful Test Flight Sets Stage for Crewed Space Mission

India’s space agency, the Indian Space Research Organization (ISRO), has taken a significant step forward in its ambitious Gaganyaan project by successfully conducting the first in a series of test flights. The project aims to send astronauts into space by 2025, making India the fourth country, after the Soviet Union, the United States, and China, to achieve this milestone.

The Gaganyaan spacecraft took to the skies at 10:00 local time (04:30 UTC) on Saturday from the Sriharikota launch site. Notably, this was the second attempt on the same day, as the first launch was put on hold just five seconds before its scheduled liftoff.

The primary objective of this test flight, known as the Flight Test Vehicle Abort Mission-1 (TV-D1), was to ascertain the spacecraft’s ability to safely rescue the crew in the event of a rocket malfunction. This “crew escape system (CES),” a critical component, had to prove its effectiveness during the test.

S Somanath, the Chairman of ISRO, announced the success of the mission, eliciting cheers and applause from his colleagues. The positive outcome of this test flight now paves the way for a series of unmanned missions, including sending a robot into space next year.

The Gaganyaan project, named after the Sanskrit word for “craft” or “vehicle to the sky,” has been developed at a cost of 90 billion rupees ($1 billion; £897 million). Its mission objective is to send a crew of three astronauts into low-Earth orbit, circling at an altitude of 400 kilometers (248 miles), for a duration of three days. Success in this endeavor will position India alongside the elite spacefaring nations.

However, before embarking on this monumental mission, ISRO needed to confirm the safe return of the human-carrying capsule. This crucial safety aspect was addressed in the TV-D1 test flight, where the ability to ensure the crew’s safety by moving them at least 2 kilometers (1.2 miles) away from the rocket in case of an emergency was demonstrated.

As part of the post-launch procedure, a series of parachutes were deployed to guide the module safely to the waters of the Bay of Bengal, approximately 10 kilometers from the Sriharikota coast. The Indian navy, with a ship and a team of divers, was prepared to recover the module and return it to shore.

The Gaganyaan test vehicle, equipped with cameras and instruments, collected valuable data and imagery during the mission. ISRO expects that this data will aid in conducting further tests and preparing for the final Gaganyaan mission.

With the successful completion of this test, ISRO is set to send a humanoid robot, named Vyommitra (Sanskrit for “space friend”), into space within an unmanned Gaganyaan spacecraft next year. The agency has also been diligently preparing Indian air force pilots, selected to be part of the crew, by subjecting them to a battery of tests, including extensive physical exercise, lab investigations, radiological assessments, clinical tests, and evaluations of their psychological fitness.

The Gaganyaan test flight generated substantial interest in India, even though it came more than half a century after astronauts from the Soviet Union and the United States embarked on journeys to low Earth orbit. China became the third nation to achieve spaceflight in 2003. India’s recent historic lunar landing near the Moon’s south pole in August 2023 and the launch of the Aditya-L1, its first Sun observation mission, have also elevated its space achievements.

In a bold vision for the future, India announced plans to establish a space station by 2035 and send an astronaut to the Moon by 2040, reaffirming its commitment to expanding its presence in space exploration.

NASA’s Voyager Spacecraft Receive Software Patch to Extend Their Mission

In an ongoing effort to extend the life of NASA’s Voyager 1 and Voyager 2 spacecraft, a team of dedicated engineers and scientists is working diligently to address the myriad challenges posed by the aging deep-space explorers. Launched nearly half a century ago, these iconic vessels have ventured into the far reaches of interstellar space, where their primary mission is to study cosmic rays, the magnetic field, and the plasma environment.

These missions, despite their age, continue to provide valuable scientific data. Nevertheless, as the years have gone by, the Voyagers have encountered several technical issues that necessitate creative solutions to ensure their continued functionality. Suzanne Dodd, Voyager project manager at NASA’s Jet Propulsion Laboratory, emphasized the importance of prolonging the mission’s longevity.

“These are measures that we’re trying to take to extend the life of the mission,” Dodd stated.

One of the primary challenges faced by the Voyager team is the lack of redundancy in the spacecraft. After more than four decades in space, the Voyagers no longer possess backup systems, meaning that a failure of a single component could jeopardize the entire mission.

“Everything on both spacecraft is single-string,” Dodd explained. “There are not any backup capabilities left. In some cases, we powered off stuff to save power, just to keep the instruments on.”

To address recent issues and ensure the continued success of the missions, NASA has taken innovative approaches. Ground controllers at JPL recently uplinked a software patch to Voyager 2, as a test before deploying the same patch to Voyager 1. The patch aims to rectify a computer issue that had persisted since 2022, where the Voyager 1 computer responsible for orienting the spacecraft was sending garbled status reports.

Furthermore, engineers have developed a new strategy for operating the spacecraft’s thrusters. These thrusters are essential for keeping the main antenna on each probe pointed at Earth, and there is a buildup of propellant residue in the narrow lines that feed hydrazine fuel to the thrusters. While this approach may result in occasional data loss, it will significantly extend the overall mission by preventing the complete blockage of the propellant inlet tubes.

“These two spacecraft are still operating, still returning uniquely valuable science data, and every extra day we get data back is a blessing,” Dodd emphasized.

Another pressing issue is the spacecraft’s declining power levels, as they rely on nuclear batteries that gradually produce less electricity each year. The power situation is currently stable and predictable, but as the batteries continue to degrade, NASA anticipates having to deactivate Voyager’s science instruments one by one late in the decade. Once the transmitter’s power requirements exceed the available power, the mission will come to an end.

Nevertheless, the Voyagers continue to push the boundaries of space exploration. Both spacecraft are now in the realm of interstellar space, representing the farthest human-made objects from Earth. These pioneering missions have not only provided an invaluable wealth of scientific knowledge but have also become a testament to the ingenuity and resourcefulness of NASA’s engineering and science teams.

“If you only look at the power situation, the Voyagers should make it until 2030, and maybe slightly longer,” Dodd stated. “But there are a lot of other issues that could pop up and cause a mission to fail.”

With contact still maintained with the Voyagers, albeit with a small team, it is NASA’s hope that these venerable spacecraft will continue their journey and provide insights into the mysteries of the universe for years to come.

“They’ve overcome lots of issues, and the engineers have been very clever in overcoming those issues,” Dodd concluded. “I think the focus now is let’s get to 50 and have the biggest party we can.”

+ Ray Crafton, KN2K, presents a “Simple, Portable Satellite Tracker” in the ARRL QST November 2023 edition. This tracker utilizes two servo gearboxes, SatPC32 for control, and an Arduino Uno for translation of commands. It is powered by a 13.8 VDC source, typically a 30 Ah lithium iron phosphate battery. The tracker consists of four subsystems: servo mount, adaptable antenna mount, servo control box, and control software interpreting SatPC32 commands. The servo mount includes Stingray-4 and Stingray-9 gearboxes for azimuth and elevation. The antenna mount offers flexibility for accommodating a range of antennas, and the servo control box houses an Arduino Uno along with power converters. For detailed construction notes and updates, the ARRL website https://www.arrl.org/qst-in-depth provides additional resources and information.

+ NASA has revealed that it has already processed 70.3 grams of rocks and dust collected by the OSIRIS-REx mission from asteroid Bennu. That means the mission has way exceeded its goal of bringing 60 grams of asteroid samples back to Earth — especially since NASA scientists have yet to open the primary sample container that made its way back to our planet in September. Apparently, they’re struggling to open the container and could not remove two of its 35 fasteners using the tools currently available to them. The scientists are processing the samples inside a specialized glovebox with a flow of nitrogen in order to keep them from being exposed to our atmosphere and any contaminants. They can’t just use any implement to break the container’s fasteners open either: The tool must fit inside the glovebox, and it also must not compromise the samples’ integrity. NASA has sealed the primary container sample for now, while it’s developing the procedure to be able to open it over the next few weeks. (ANS thanks Engadget for the above information)

+ SpaceX will launch four European navigation satellites for the ESA due to delays in European launcher development. The agreement entails two Falcon 9 launches in 2024, each carrying two Galileo navigation satellites, pending approval from the European Commission and EU member states. Europe’s preference was to use its own rockets, like Ariane 6 and Vega-C, but technical issues led them to seek SpaceX’s services. The ongoing conflict between Russia and Ukraine ruled out the use of Soyuz rockets. These Galileo satellites are crucial for maintaining an independent European global satellite navigation system, and they contain encrypted communication equipment for European military use. This marks the first time in 15 years that Galileo satellites will launch from outside Europe and the first instance of SpaceX launching European satellites with classified equipment.

+ SpaceX plans to launch 144 missions in the coming year, aiming to increase its already impressive launch frequency. In 2023, the company has already completed 74 orbital missions, breaking its own previous record of 61 set in 2022. SpaceX intends to reach 100 flights this year, requiring a significant acceleration in launch cadence. They aim to achieve approximately 12 flights per month in 2024. Most of these missions will be dedicated to the Starlink internet-satellite megaconstellation. While Falcon 9 and Falcon Heavy rockets have dominated SpaceX’s missions so far, they are working on their reusable Starship rocket for future exploration, with a second test flight pending approval from the U.S. Federal Aviation Administration. SpaceX aims for rapid hardware development through frequent test flights despite regulatory challenges. (ANS thanks Space.com for the above information)
