NASA Stennis Autonomous Systems Laboratory Project Engineer Travis Martin monitors successful data delivery from the center’s ASTRA payload aboard the orbiting Sidus Space LizzieSat-1 satellite. The ASTRA autonomous systems hardware/software payload represents the first-ever in-space mission for NASA Stennis. NASA/Danny Nowlin NASA’s Stennis Space Center and partner Sidus Space Inc. announced primary mission success July 2 for the center’s historic in-space mission – an autonomous systems payload aboard an orbiting satellite.
“Our ASTRA (Autonomous Satellite Technology for Resilient Applications) payload is active and operational,” NASA Stennis Center Director John Bailey said. “This is an incredible achievement for Stennis, our first-ever in-space mission flying on a new state-of-the-art satellite. We are all celebrating the news.”
ASTRA is the on-orbit payload mission developed by NASA Stennis and is an autonomous systems hardware/software payload. The NASA Stennis ASTRA technology demonstrator is a payload rider aboard the Sidus Space premier satellite, LizzieSat-1 (LS-1) small satellite. Partner Sidus Space is responsible for all LS-1 mission operations, including launch and satellite activation, which allowed the NASA Stennis ASTRA team to complete its primary mission objectives.
LS-1 launched into space on the SpaceX Transporter 10 rideshare mission March 4 and deployed the same day. The LS-1 satellite commissioning began after deployment and was completed on May 12. Sidus Space’s next step was to begin activation of payloads, including ASTRA.
After the payload was activated, the NASA Stennis Autonomous Systems Laboratory (ASL) team confirmed they had established a telemetry link to send and receive data in the ASTRA Payload Operation Command Center. The ASL team continued to checkout and verify operation of ASTRA and has confirmed that ASTRA primary mission objectives have been successfully achieved.
“This is just a remarkable and inspiring accomplishment for the entire team,” said Chris Carmichael, NASA Stennis ASL branch chief. “So many people put in a tremendous effort to bring us to this point. It is a great demonstration of the team’s vision and capabilities, and I am excited to see what the future holds.”
The NASA Stennis ASL works to create safe-by-design autonomous systems. ASTRA demonstrates technology that is required by NASA and industry for upcoming space missions. The ASTRA computer on the satellite runs a digital twin of satellite systems, which detects and identifies the causes of anomalies, and autonomously generates plans to resolve those issues. Ultimately, ASTRA will demonstrate autonomous operations of LS-1.
“Achieving ASTRA’s primary mission objectives underscores our dedication and commitment to driving innovation while advancing space technology alongside NASA, our trusted partner,” said Carol Craig, Founder and CEO of Sidus Space. “We are proud to support such groundbreaking projects in our industry and eagerly anticipate the continued progress of our LizzieSat-1 mission.”
The success of the ASTRA mission comes as NASA Stennis moves forward with strategic plans to design autonomous systems that will help accelerate development of intelligent aerospace systems and services for government and industry.

On June 21, three days before crew egress, about 200 people gathered at Space Center Houston’s theater for a live Q&A session where students had the opportunity to share their questions with crew members Al Romaithi and Wijesekara. They discussed team dynamics, adapting to unexpected circumstances, and coping with isolation.
When asked about what prompted her to apply for the mission, Wijesekara emphasized the importance of helping NASA collect data that could help future long-duration space flights, saying, “This will be very useful when we get to the Moon with Artemis missions and even beyond that when we go to Mars.”

When a student asked about building stronger teams, Wijesekara advised, “Spend time with your crewmates, get to know them deeply, and be a good listener.”
Al Romaithi, who hails from the UAE, shared that his academic background in aerospace engineering and aviation helped him stand out in the application process. In addition, this HERA campaign is focused on cultural diversity, which opened the opportunity for him to apply through a partnership between HERA and MBRSC.
Discussing the mental effects of isolation, Al Romaithi highlighted the comfort provided by personal items, books, and board games. Wijesekara noted that the white noise of instruments running became their constant companion that her senses adjusted to over time.
Wijesekara told the audience her favorite experience was performing spacewalks and “flying drones on Mars,” via virtual reality, which allowed them to observe Martian landscapes and even lava caves. Through the habitat’s window screens, they could see simulated views of space and Martian landscapes.
The crew addressed the challenges they faced inside the analog environment, such as communication delays, which taught them teamwork, patience, and precise planning. They utilized a 3D printer aboard HERA to address equipment issues. A curious student asked what happens to the crew and the mission in case of an outside emergency, like a hurricane. Both crew members explained that HERA provided them with step-by-step emergency instructions.
Medical evaluations and nutrition-specific meal plans were crucial for the mission, Al Romaithi and Wijesekara noted, with daily monitoring of the crew’s physical and mental health. The crew also grew lettuce hydroponically and had four pet triops shrimp named Buzz, Alvin, Simon, and Theodore.
When a student asked what food he missed most, Al Romaithi replied, “Home-cooked meals.”
Wijesekara shared the first thing she plans to do post-mission is see her family and visit a list of restaurants with her crewmates. She also looks forward to running on the beach.
Reflecting on their experience, Al Romaithi noted, “We’ve become more disciplined and efficient in our daily activities.”
What was the most valuable lesson learned? “The importance of teamwork and communication,” he said.
Both crewmembers also gave students in the audience some advice. “Never hesitate or be shy to ask for help,” Al Romaithi said. “Always push for your biggest dreams, don’t let self-doubt slow you down, and believe in yourself.”
“And keep studying!” added Wijesekara.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
The four CubeSate spacecraft that make up the Starling swarm have demonstrated success in autonomous operations, completing all key mission objectives. After ten months in orbit, the Starling spacecraft swarm successfully demonstrated its primary mission’s key objectives, representing significant achievements in the capability of swarm configurations.
Swarms of satellites may one day be used in deep space exploration. An autonomous network of spacecraft could self-navigate, manage scientific experiments, and execute maneuvers to respond to environmental changes without the burden of significant communications delays between the swarm and Earth.
“The success of Starling’s initial mission represents a landmark achievement in the development of autonomous networks of small spacecraft,” said Roger Hunter, program manager for NASA’s Small Spacecraft Technology program at NASA’s Ames Research Center in California’s Silicon Valley. “The team has been very successful in achieving our objectives and adapting in the face of challenges.”
Sharing the Work
The Distributed Spacecraft Autonomy (DSA) experiment, flown onboard Starling, demonstrated the spacecraft swarm’s ability to optimize data collection across the swarm. The CubeSats analyzed Earth’s ionosphere by identifying interesting phenomena and reaching a consensus between each satellite on an approach for analysis.
By sharing observational work across a swarm, each spacecraft can “share the load” and observe different data or work together to provide deeper analysis, reducing human workload, and keeping the spacecraft working without the need for new commands sent from the ground.
The experiment’s success means Starling is the first swarm to autonomously distribute information and operations data between spacecraft to generate plans to work more efficiently, and the first demonstration of a fully distributed onboard reasoning system capable of reacting quickly to changes in scientific observations.
Communicating Across the Swarm
A swarm of spacecraft needs a network to communicate between each other. The Mobile Ad-hoc Network (MANET) experiment automatically established a network in space, allowing the swarm to relay commands and transfer data between one another and the ground, as well as share information about other experiments cooperatively.
The team successfully completed all the MANET experiment objectives, including demonstrating routing commands and data to one of the spacecraft having trouble with space to ground communications, a valuable benefit of a cooperative spacecraft swarm.
“The success of MANET demonstrates the robustness of a swarm,” said Howard Cannon, Starling project manager at NASA Ames. “For example, when the radio went down on one swarm spacecraft, we ‘side-loaded’ the spacecraft from another direction, sending commands, software updates, and other vital information to the spacecraft from another swarm member.”
Autonomous Swarm Navigation
Navigating and operating in relation to one another and the planet is an important part of forming a swarm of spacecraft. Starling Formation-Flying Optical Experiment, or StarFOX, uses star trackers to recognize a fellow swarm member, other satellite, or space debris from the background field of stars, then estimate each spacecraft’s position and velocity.
The experiment is the first-ever published demonstration of this type of swarm navigation, including the ability to track multiple members of a swarm simultaneously and the ability to share observations between the spacecraft, improving accuracy when determining each swarm member’s orbit.
Near the end of mission operations, the swarm was maneuvered into a passive safety ellipse, and in this formation, the StarFOX team was able to achieve a groundbreaking milestone, demonstrating the ability to autonomously estimate the swarm’s orbits using only inter-satellite measurements from the spacecraft star trackers.
Managing Swarm Maneuvers
The ability to plan and execute maneuvers with minimal human intervention is an important part of developing larger satellite swarms. Managing the trajectories and maneuvers of hundreds or thousands of spacecraft autonomously saves time and reduces complexity.
The Reconfiguration and Orbit Maintenance Experiments Onboard (ROMEO) system tests onboard maneuver planning and execution by estimating the spacecraft’s orbit and planning a maneuver to a new desired orbit.
The experiment team has successfully demonstrated the system’s ability to determine and plan a change in orbit and is working to refine the system to reduce propellant use and demonstrate executing the maneuvers. The team will continue to adapt and develop the system throughout Starling’s mission extension.
Swarming Together
Now that Starling’s primary mission objectives are complete, the team will embark on a mission extension known as Starling 1.5, testing space traffic coordination in partnership with SpaceX’s Starlink constellation, which also has autonomous maneuvering capabilities. The project will explore how constellations operated by different users can share information through a ground hub to avoid potential collisions.
“Starling’s partnership with SpaceX is the next step in operating large networks of spacecraft and understanding how two autonomously maneuvering systems can safely operate in proximity to each other. As the number of operational spacecraft increases each year, we must learn how to manage orbital traffic,” said Hunter.
NASA’s Small Spacecraft Technology program, based at Ames and within NASA’s Space Technology Mission Directorate (STMD), funds and manages the Starling mission. Blue Canyon Technologies designed and manufactured the spacecraft buses and is providing mission operations support. Rocket Lab USA, Inc. provided launch and integration services. Partners supporting Starling’s payload experiments have included Stanford University’s Space Rendezvous Lab in Stanford, California, York Space Systems (formerly Emergent Space Technologies) of Denver, Colorado, CesiumAstro of Austin, Texas, L3Harris Technologies, Inc., of Melbourne, Florida. Funding support for the DSA experiment was provided by NASA’s Game Changing Development program within STMD. Partners supporting Starling’s mission extension include SpaceX of Hawthorne, California, NASA’s Conjunction Assessment Risk Analysis (CARA) program, and the Department of Commerce. SpaceX manages the Starlink satellite constellation and the Collision Avoidance ground system.
