Today's brief highlights a landmark cooperation between NASA and China to prevent satellite collision, strategic steps in American space leadership through nuclear energy, a U.S. military missile test, and more.
Today’s Space Brief covers significant developments such as SpaceX’s latest Starlink launch, the US Space Force testing modular satellite technology, and key long-range missile tests by the Pentagon.
Today's highlights include a space debris incident involving China's spacecraft, development advancements for military space missions, and a notable setback for SpaceX's Starship booster.
SpaceX launched Starlink batches from Vandenberg and Cape Canaveral within 48 hours, pushing the active constellation toward 10,000 operational satellites.
Thirty-five years ago, NASA's Galileo spacecraft made a crucial flyby of Venus, pioneering a complex path through the inner solar system that would revolutionize planetary exploration
AST SpaceMobile's BlueBird constellation is a bet that raw aperture size wins. Each satellite unfolds a 64-square-meter phased-array antenna in orbit, the largest commercial antenna ever deployed. The company claims a stock smartphone on the ground can connect directly to it. The competition says the physics doesn't support that. Seventeen satellites in and a contract with AT&T, Verizon, and Vodafone, somebody's math is wrong.
On February 2, 1909, Robert Goddard made a revolutionary breakthrough in his notebook: liquid oxygen and liquid hydrogen could achieve 50% efficiency in converting heat energy to kinetic energy for rocket propulsion
SpaceX readies Starship Flight 13 for July 16 launch to deploy first Starlink V3 satellites as Falcon 9 logs its 600th booster reuse.
