@orbitalradar.bsky.socialFUN FACT: In 2009, two satellites collided at 11.7 km/s, creating 2,000 fragments. Still in orbit, they echo the importance of conjunction screening.
Right now, 31,521 objects fill our skies.

@spaceflightpedia.comTwo first-grade classmates became the first women to fly in space together. Forty-two years ago today, Kathryn Sullivan and Sally Ride launched aboard Challenger on STS-41-G. On October 11, 1984, Sullivan became the first American woman to walk in space.
@spaceflightpedia.comA satellite designed to last 2 years kept working for 21. Today in 1984, Challenger released ERBS with a stuck solar panel. Sally Ride shook the satellite with the robotic arm and moved the panel into sunlight, where it opened.

@spaceflightpedia.comSixty-one years ago today, on October 4, 1965, the Soviet Union launched Luna 7 to attempt a soft Moon landing. Its optical sensor, set at the wrong angle, lost sight of Earth, and the main engine never fired. It crashed west of Kepler crater on October 7. #Spaceflightpedia #Luna7 #SpaceHistory

@spaceflightpedia.comSixty-six years ago today, Courier 1B launched, the world's first active repeater communications satellite. After 17 days and 228 orbits, it stopped answering its own ground controllers, most likely because its clock-based access codes fell out of sync. #Spaceflightpedia #SpaceHistory #Courier1B
