NASA’s Stennis Space Center near Bay St. Louis, Mississippi, announced Wednesday it will continue its historic in-space autonomous systems payload mission aboard an orbiting satellite through a follow-on agreement with Sidus Space, Inc.

“We are excited to report the historic ASTRA (Autonomous Satellite Technology for Resilient Applications) mission will continue,” said Chris Carmichael, chief, Stennis Autonomous Systems Laboratory (ASL) branch at NASA Stennis. “We look forward to working with Sidus Space to demonstrate the capabilities of the NASA Stennis payload and our autonomous systems team.”

With this new agreement, the ASTRA payload will be used to collect onboard data on satellite systems and support management of the satellite’s Electrical Power System (EPS). The NASA Stennis ASTRA system will monitor and autonomously optimize the satellite’s battery system, ensuring the satellite continues to operate as needed for the course of its remaining mission lifetime. The ASTRA EPS management capability provides a new, innovative level of adaptability and efficiency for monitoring the satellite’s ongoing operations.

Developed by NASA Stennis to fly and demonstrate an autonomous systems hardware/software payload, ASTRA is the on-orbit mission. The NASA Stennis ASTRA technology demonstrator is a payload rider aboard the Sidus Space LizzieSat-1 (LS-1) small satellite. Partner Sidus Space is responsible for all LS-1 mission operations, including launch and satellite activation.

The LS-1 small satellite launched into space on the SpaceX Transporter 10 rideshare mission March 4 and deployed the same day. Following payload activation by Sidus Space, the NASA Stennis team worked with the company to establish a telemetry link to send and receive data in the ASTRA Payload Operation Command Center located at the NASA site. The ASL team continued to checkout and verify operation of ASTRA, confirming in early July that ASTRA primary mission objectives were successful.  

The team is now focused on demonstrating autonomous system management as part of the LS-1 satellite’s planned four-year mission. “We are excited about the opportunity to continue this unprecedented mission,” Carmichael said. “Every step helps advance our autonomous systems work and lays a foundation for continued development and success.”

The NASA Stennis ASL team works to create safe-by-design autonomous systems. NASA’s 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 key satellite systems, which identifies anomalies, and autonomously generates plans to resolve those issues.

The ongoing 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.

      NASA Assigns Astronaut Anil Menon to First Space Station Mission
      By NASA
      NASA astronaut Anil Menon poses for a portrait at NASA’s Johnson Space Center in Houston. Credit: NASA/Josh Valcarcel NASA astronaut Anil Menon will embark on his first mission to the International Space Station, serving as a flight engineer and Expedition 75 crew member.
      Menon will launch aboard the Roscosmos Soyuz MS-29 spacecraft in June 2026, accompanied by Roscosmos cosmonauts Pyotr Dubrov and Anna Kikina. After launching from the Baikonur Cosmodrome in Kazakhstan, the trio will spend approximately eight months aboard the orbiting laboratory.
      During his expedition, Menon will conduct scientific investigations and technology demonstrations to help prepare humans for future space missions and benefit humanity.
      Selected as a NASA astronaut in 2021, Menon graduated with the 23rd astronaut class in 2024. After completing initial astronaut candidate training, he began preparing for his first space station flight assignment.
      Menon was born and raised in Minneapolis and is an emergency medicine physician, mechanical engineer, and colonel in the United States Space Force. He holds a bachelor’s degree in neurobiology from Harvard University in Cambridge, Massachusetts, a master’s degree in mechanical engineering, and a medical degree from Stanford University in California. Menon completed his emergency medicine and aerospace medicine residency at Stanford and the University of Texas Medical Branch in Galveston.
      In his spare time, he still practices emergency medicine at Memorial Hermann’s Texas Medical Center and teaches residents at the University of Texas’ residency program. Menon served as SpaceX’s first flight surgeon, helping to launch the first crewed Dragon spacecraft on NASA’s SpaceX Demo-2 mission and building SpaceX’s medical organization to support humans on future missions. He served as a crew flight surgeon for both SpaceX flights and NASA expeditions aboard the space station.
      For nearly 25 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.

      "We got it from them" - Former NASA flight surgeon breaks silence about alien technology
      By USH
      In 1992, Dr. Gregory Rogers a NASA flight surgeon and former Chief of Aerospace Medicine witnessed an event that would stay with him for more than three decades. Now, after years of silence, he’s finally revealing the details of a 15-minute encounter that shattered everything he thought he knew about aerospace technology. 

      With a distinguished career that includes support for 31 space shuttle launches, training as an F-16 pilot, and deep involvement in classified aerospace programs, Dr. Rogers brings unmatched credibility to the conversation. His firsthand account of observing what appeared to be a reverse-engineered craft, emblazoned with "U.S. Air Force" markings, raises profound questions about the true timeline of UAP development and disclosure. 
      The full interview spans nearly two hours. To help navigate the discussion, here’s a timeline so you can jump to the segments that interest you most.
