Galileo satellites

Europe’s latest Galileo satellites in space have joined the operational constellation, transmitting navigation signals to three billion users across planet Earth as well as relaying distress calls to rescuers. Their entry into service follows a summer test campaign and will result in a measurable increase in positioning accuracy and improved data delivery performance of the overall Galileo system.

      Credit: NASA NASA is marking progress in strengthening the agency’s small business partnerships, supply chain resiliency, and domestic space manufacturing capabilities.
      Under the agency’s enhanced Mentor-Protégé Program, NASA has announced the first Mentor-Protégé Agreement between L3Harris Technologies, a NASA large prime contractor, and Parametric Machining, Inc., a veteran-owned small business.
      This agreement will help advance NASA’s mission by fostering innovation and reinforcing the agency’s supply chain. As NASA continues to advance the Artemis campaign, deep space exploration, and aeronautics research, partnerships like this are essential in securing a resilient and efficient supplier base.
      “We are excited to facilitate the first agreement under the newly enhanced NASA Mentor-Protégé Program,” said Dwight Deneal, assistant administrator for NASA’s Office of Small Business Programs. “This agreement, and the many that will follow, promote domestic ingenuity and manufacturing and provide opportunities for small businesses to grow and thrive within NASA’s industrial base.”
      Through Mentor-Protégé Agreements, large prime contractors serve as mentors, offering technical and business development assistance to small business protégés. This collaboration not only enhances protégés’ capabilities but also provides mentors with a stronger, more reliable subcontracting base, enabling them to fill their supply chain gaps. Additionally, protégés gain potential prime and subcontract opportunities, enhanced technical capabilities, technical training, and long-term business growth.
      Relaunched in November 2024, the merit-based NASA Mentor-Protégé Program is designed to bolster small business development while strengthening NASA’s supply chain and industry base. By focusing on a targeted set of North American Industry Classification System codes, including research and development and aerospace manufacturing, NASA ensures that participating small businesses are well-positioned to contribute to long-term mission objectives.
      The agreement between L3Harris Technologies and Parametric Machining, Inc. demonstrates the value of NASA’s revamped Mentor-Protégé Program. NASA is actively accepting new Mentor-Protégé Agreements and encourages large prime contractors and small businesses to explore the benefits of forming partnerships under the program. Participating in the Mentor-Protégé Program provides:
      Enhanced manufacturing capabilities and subcontracting opportunities. Mentorship from experienced NASA prime contractors. Opportunities to advance competitiveness in government contracts. Access to technical assistance and business development support. A pathway for small businesses to integrate into NASA’s supply chain. L3Harris Technologies is a prime contractor at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, supporting the Geostationary Extended Observations Imager Instrument Implementation contract. NASA Goddard also will serve as the administering center for this agreement.

      The Roscosmos Soyuz MS-27 spacecraft will launch from the Baikonur Cosmodrome in Kazakhstan to the International Space Station with (pictured left to right) NASA astronaut Jonny Kim and Roscosmos cosmonauts Sergey Ryzhikov and Alexey Zubritsky.Credit: Gagarin Cosmonaut Training Center NASA astronaut Jonny Kim will launch aboard the Roscosmos Soyuz MS-27 spacecraft to the International Space Station, accompanied by cosmonauts Sergey Ryzhikov and Alexey Zubritsky, where they will join the Expedition 72/73 crew in advancing scientific research.
      Kim, Ryzhikov, and Zubritsky will lift off at 1:47 a.m. EDT Tuesday, April 8 (10:47 a.m. Baikonur time) from the Baikonur Cosmodrome in Kazakhstan.
      Watch live launch and docking coverage on NASA+. Learn how to watch NASA content through a variety of platforms.
      After a two-orbit, three-hour trajectory to the station, the spacecraft will dock automatically to the station’s Prichal module at approximately 5:03 a.m. Shortly after, hatches will open between Soyuz and the space station.
      Once aboard, the trio will join NASA astronauts Nichole Ayers, Anne McClain, and Don Pettit, JAXA (Japan Aerospace Exploration Agency) astronaut Takuya Onishi, and Roscosmos cosmonauts Alexey Ovchinin, Kirill Peskov, and Ivan Vagner.
      NASA’s coverage is as follows (all times Eastern and subject to change based on real-time operations):
      Tuesday, April 8
      12:45 a.m. – Launch coverage begins on NASA+.
      1:47 a.m. – Launch
      4:15 a.m. – Rendezvous and docking coverage begins on NASA+.
      5:03 a.m. – Docking
      7 a.m. – Hatch opening and welcome remarks coverage begins on NASA+.
      7:20 a.m. – Hatch opening
      The trio will spend approximately eight months aboard the orbital laboratory as Expedition 72 and 73 crew members before returning to Earth in December. This will be the first flight for Kim and Zubritsky, and the third for Ryzhikov.
      For more than two decades, people have lived and worked continuously aboard the International Space Station, advancing scientific knowledge and making research breakthroughs that are not possible on Earth. The station is a critical testbed for NASA to understand and overcome the challenges of long-duration spaceflight and to expand commercial opportunities in low Earth orbit. As commercial companies focus on providing human space transportation services and destinations as part of a robust low Earth orbit economy, NASA is focusing more resources on deep space missions to the Moon as part of the Artemis campaign in preparation for future human missions to Mars.
