Four NASA astronauts will participate in a welcome home ceremony at Space Center Houston after recently returning from missions aboard the International Space Station.

NASA astronauts Nick Hague, Suni Williams, Butch Wilmore, and Don Pettit will share highlights from their missions at 6 p.m. CDT Thursday, May 22, during a free, public event at NASA Johnson Space Center’s visitor center. The astronauts also will recognize key mission contributors during an awards ceremony after their presentation.

Williams and Wilmore launched aboard Boeing’s Starliner spacecraft and United Launch Alliance Atlas V rocket on June 5, 2024, from Space Launch Complex 41 as part of NASA’s Boeing Crew Flight Test. The duo arrived at the space station on June 6. In August, NASA announced the uncrewed return of Starliner to Earth and integrated Wilmore and Williams with the Expedition 71/72 crew and a return on Crew-9.

Hague launched Sept. 28, 2024, with Roscosmos cosmonaut Aleksandr Gorbunov aboard a SpaceX Falcon 9 rocket from Space Launch Complex 40 at Cape Canaveral Space Force Station in Florida as part of NASA’s SpaceX Crew-9 mission. The next day, they docked to the forward-facing port of the station’s Harmony module.

Hague, Gorbunov, Wilmore, and Williams returned to Earth on March 18, 2025, splashing down safely off the coast of Tallahassee, Florida, in the Gulf of America.

Williams and Wilmore traveled 121,347,491 miles during their mission, spent 286 days in space, and completed 4,576 orbits around Earth. Hague and Gorbunov traveled 72,553,920 miles during their mission, spent 171 days in space, and completed 2,736 orbits around Earth. Hague has logged 374 days in space during two missions. It was the third spaceflight for both Williams and Wilmore. Williams has logged 608 total days in space, and Wilmore has logged 464 days.

Pettit launched aboard the Soyuz MS-26 spacecraft on Sept. 11, 2024, alongside Roscosmos cosmonauts Alexey Ovchinin and Ivan Vagner. The seven-month research mission as an Expedition 72 flight engineer was the fourth spaceflight of Pettit’s career, completing 3,520 orbits of the Earth and a journey of 93.3 million miles. He has logged a total of 590 days in orbit. Pettit and his crewmembers safely landed in Kazakhstan on April 19, 2025 (April 20, 2025, Kazakhstan time).

The Expedition 72 crew dedicated more than 1,000 combined hours to scientific research and technology demonstrations aboard the International Space Station. Their work included enhancing metal 3D printing capabilities in orbit, exploring the potential of stem cell technology for treating diseases, preparing the first wooden satellite for deployment, and collecting samples from the station’s exterior to examine whether microorganisms can survive in the harsh environment of space. They also conducted studies on plant growth and quality, investigated how fire behaves in microgravity, and advanced life support systems, all aimed at improving the health, safety, and sustainability of future space missions. Pettit also used his spare time and surroundings aboard station to conduct unique experiments and captivate the public with his photography. Expedition 72 captured a record one million photos during the mission, showcasing the unique research and views aboard the orbiting laboratory through astronauts’ eyes.

For more than 24 years, people have lived and worked continuously aboard the International Space Station, advancing scientific knowledge, and conducting critical research for the benefit of humanity and our home planet. Space station research supports the future of human spaceflight as NASA looks toward deep space missions to the Moon under the Artemis campaign and in preparation for future human missions to Mars, as well as expanding commercial opportunities in low Earth orbit and beyond.

      Software designed to give spacecraft more autonomy could support a future where swarms of satellites navigate and complete scientific objectives with limited human intervention.
      Caleb Adams, Distributed Spacecraft Autonomy project manager, monitors testing alongside the test racks containing 100 spacecraft computers at NASA’s Ames Research Center in California’s Silicon Valley. The DSA project develops and demonstrates software to enhance multi-spacecraft mission adaptability, efficiently allocate tasks between spacecraft using ad-hoc networking, and enable human-swarm commanding of distributed space missions. Credit: NASA/Brandon Torres Navarrete Astronauts living and working on the Moon and Mars will rely on satellites to provide services like navigation, weather, and communications relays. While managing complex missions, automating satellite communications will allow explorers to focus on critical tasks instead of manually operating satellites.  
      Long duration space missions will require teaming between systems on Earth and other planets. Satellites orbiting the Moon, Mars, or other distant areas face communications delays with ground operators which could limit the efficiency of their missions.  
      The solution lies within the Distributed Spacecraft Autonomy (DSA) project, led by NASA’s Ames Research Center in California’s Silicon Valley, which tests how shared autonomy across distributed spacecraft missions makes spacecraft swarms more capable of self-sufficient research and maintenance by making decisions and adapting to changes with less human intervention. 
      Adding autonomy to satellites makes them capable of providing services without waiting for commands from ground operators. Distributing the autonomy across multiple satellites, operating like a swarm, gives the spacecraft a “shared brain” to accomplish goals they couldn’t achieve alone. 
      The DSA software, built by NASA researchers, provides the swarm with a task list, and shares each spacecraft’s distinct perspective – what it can observe, what its priorities are – and integrates those perspectives into the best plan of action for the whole swarm. That plan is supported by decision trees and mathematical models that help the swarm decide what action to take after a command is completed, how to respond to a change, or address a problem. 
      Sharing the Workload
      The first in-space demonstration of DSA began onboard the Starling spacecraft swarm, a group of four small satellites, demonstrating various swarm technologies. Operating since July 2023, the Starling mission continues providing a testing and validation platform for autonomous swarm operations. The swarm first used DSA to optimize scientific observations, deciding what to observe without pre-programmed instructions. These autonomous observations led to measurements that could have been missed if an operator had to individually instruct each satellite. 
      The Starling swarm measured the electron content of plasma between each spacecraft and GPS satellites to capture rapidly changing phenomena in Earth’s ionosphere – where Earth’s atmosphere meets space. The DSA software allowed the swarm to independently decide what to study and how to spread the workload across the four spacecraft. 
      Because each Starling spacecraft operates as an independent member within the swarm, if one swarm member was unable to accomplish its work, the other three swarm members could react and complete the mission’s goals. 
      The Starling 1.0 demonstration achieved several firsts, including the first fully distributed autonomous operation of multiple spacecraft, the first use of space-to-space communications to autonomously share status information between multiple spacecraft, the first demonstration of fully distributed reactive operations onboard multiple spacecraft, the first use of a general-purpose automated reasoning system onboard a spacecraft, and the first use of fully distributed automated planning onboard multiple spacecraft. These achievements laid the groundwork for Starling 1.5+, an ongoing continuation of the satellite swarm’s mission using DSA.

      After DSA’s successful demonstration on Starling 1.0, the team began exploring additional opportunities to use the software to support satellite swarm health and efficiency. Continued testing of DSA on Starling’s extended mission included PLEXIL (Plan Execution Interchange Language), a NASA-developed programming language designed for reliable and flexible automation of complex spacecraft operations. 
      Onboard Starling, the PLEXIL application demonstrated autonomous maintenance, allowing the swarm to manage normal spacecraft operations, correct issues, or distribute software updates across individual spacecraft.  
      Enhanced autonomy makes swarm operation in deep space feasible – instead of requiring spacecraft to communicate back and forth between their distant location and Earth, which can take minutes or hours depending on distance, the PLEXIL-enabled DSA software gives the swarm the ability to make decisions collaboratively to optimize their mission and reduce workloads. 
      Simulated Lunar Swarming 
      To understand the scalability of DSA, the team used ground-based flight computers to simulate a lunar swarm of virtual small spacecraft. The computers simulated a swarm that provides position, navigation, and timing services on the Moon, similar to GPS services on Earth, which rely on a network of satellites to pinpoint locations. 
      The DSA team ran nearly one hundred tests over two years, demonstrating swarms of different sizes at high and low lunar orbits. The lessons learned from those early tests laid the groundwork for additional scalability studies. The second round of testing, set to begin in 2026, will demonstrate even larger swarms, using flight computers that could later go into orbit with DSA software onboard. 
      The Future of Spacecraft Swarms 
      Orbital and simulated tests of DSA are a launchpad to increased use of distributed autonomy across spacecraft swarms. Developing and proving these technologies increases efficiency, decreases costs, and enhances NASA’s capabilities opening the door to autonomous spacecraft swarms supporting missions to the Moon, Mars, and beyond.
