SpaceX sets a new reusability record and continues its busy launch schedule with multiple Starlink missions.
Starlink satellites fired their thrusters to dodge a collision roughly 300,000 times in 2025, about 822 times a day. Behind that number is a fragile, half-automated system of warnings, probabilities, and judgment calls that decides which close approaches are worth a maneuver and which are just noise.
Today's highlights include China's remote-sensing satellite launch, U.S. Space Force's investment in missile-tracking satellites, and NASA's MAVEN milestone on Mars.
Key highlights include the launch of a Navy SEAL astronaut to the ISS, multi-billion dollar contracts awarded by the US Space Force, advancements in secure GPS technology, and a strategic ISR arrangement.
SpaceX scrubs Crew-10 launch due to hydraulics issue; successful Falcon 9 launch for NASA missions, and Texas supports SpaceX expansion.
Today's brief highlights the U.S. Space Force's upcoming modular satellite mission, increased military reliance on commercial space intelligence, and the demand for expanded commercial reserve support. Learn more about these advancements alongside our Satellite Spotlight on Yaogan-30 B.
