Today's brief covers next-generation missile defense strategies, NASA's Dream Chaser contract updates, and technological advances in Air Force cyber defense.
Today's Space Brief covers China’s latest satellite launches, leadership changes in the U.S. Space Force, insights from hyperspectral imagery on an Iranian facility, SpaceX's Starlink mission, and more.
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 new ESA Euclid data, upcoming Blue Origin flight, and multiple Starlink launches, delivering fresh satellite tracking opportunities.
GPS III SV10 launched April 21 on a SpaceX Falcon 9 with 3x better accuracy and 8x anti-jamming. Starlink stands at 10,263 working satellites.
SpaceX breaks records with its 94th launch of the year while planning to ramp up Starship production to unprecedented levels.
SpaceX successfully launched 29 Starlink satellites, bolstering its broadband network and expanding global internet coverage.
Today's brief covers the future of military space operations, ESA's potential defense role, significant developments in satellite communications, and SpaceX's response to Artemis 3 comments.
