The Justice Department seized domains associated with QScan and QTRouter, platforms it alleges were used in a Chinese state-sponsored hacking campaign. Court documents say the operation reached U.S. government agencies and networks operated by hospitals, telecommunications providers, power companies, financial institutions and defense contractors.
Spire Global will develop and flight-qualify a satellite and hyperspectral microwave sounder under a two-year, $28 million NOAA contract, targeting operational weather capability by 2030. Separately, LeoLabs won a $20.68 million Space Force contract to deliver and demonstrate a transportable Scout surveillance radar for a defense mission.
NASA will omit cubesat secondary payloads from Artemis 3 after carrying small satellites on the first two Space Launch System missions. The change reduces the mission’s rideshare activity and underscores the evolving payload priorities for the next Artemis flight to the Moon.

NASA’s Nancy Grace Roman Space Telescope has arrived at SpaceX’s hangar at Launch Complex 39A ahead of its scheduled Aug. 30 launch. The observatory is designed to discover thousands of exoplanets and produce a statistical census of planetary systems, complementing capabilities unavailable from Hubble and JWST.
NASA and Advanced Space are developing a pair of small satellites as a follow-on to the CAPSTONE CubeSat mission. The spacecraft will test rendezvous and proximity operations around the moon, advancing capabilities needed for future lunar missions and more complex cislunar activity.

NASA astronaut Anil Menon and ESA astronaut Sophie Adenot completed a 6.5-hour spacewalk on Aug. 25, installing a replacement Space-to-Ground antenna outside the International Space Station. The task followed their Aug. 18 removal of a faulty antenna and concluded with the spacewalkers returning inside at 2:57 p.m. EDT.
A team of NASA satellites successfully demonstrated navigation without GPS in what NASA describes as the world’s first “lost-in-space” experiment. The result is enabling the satellites to extend their mission in orbit and validates alternative navigation methods for spacecraft operating beyond conventional GPS coverage.
