@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.
@playdeltav.bsky.social22 years ago today: The Ansari X Prize is won.
SpaceShipOne flew above a hundred kilometres twice within two weeks and took the ten-million-dollar prize. 17 orbital launches have flown on this date.

@mabelquill.bsky.socialSputnik Opens the Space Age On October 4, 1957, the Soviet Union launched Sputnik 1, the world’s first artificial satellite, into Earth orbit. #TodayInHistory #MabelQuill #Sputnik1 #SpaceAge #SpaceHistory #HistoryTok #HistoryFacts #LearnHistory #fyp
@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
@spaceflightpedia.comSputnik’s 26-metre rocket stage outshone the satellite itself. Sixty-nine years ago today, on 4 October 1957, Sputnik 1 launched. The 83.6 kg sphere shone at sixth magnitude. Its R-7 core stage, fitted with reflective panels, appeared at first magnitude.
@playdeltav.bsky.social69 years ago today: Sputnik.
Sputnik 1 reached orbit and broadcast a tone that anyone with a shortwave radio could hear, opening the space age. 17 orbital launches have flown on this date.

@spaceflightpedia.comForty-one years ago today, on October 3, 1985, Space Shuttle Atlantis made its first launch on STS-51-J, a classified military mission. Commander Karol Bobko became the first astronaut to fly on three different shuttle orbiters.

@playdeltav.bsky.social64 years ago today: NASA launched Mercury-Atlas 8 on Atlas LV-3B.
25 ships in Delta-V, none of which fly the same. Thrust, fuel, handling and tolerance are the whole argument for taking one over another.
@valdeloir.bsky.social
@vacuumfiles.bsky.socialThe capsule landed perfectly. All three men inside were dead.
June 30, 1971: a valve on Soyuz 11 opened to space during the descent. The air escaped in less than a minute.

@orbitalradar.bsky.socialFUN FACT: Why did it take two decades for another woman to orbit Earth after Valentina Tereshkova?
She flew at 26, orbiting 48 times—more than all American astronauts before her combined!
See who’s up there now: 31,428 tracked objects in orbit.
@spaceflightpedia.comSixty-eight years ago today, on October 1, 1958, NASA began operating with 8,000 employees inherited from NACA and three research laboratories. It also took in Project Vanguard, the Jet Propulsion Laboratory and von Braun's Army Ballistic Missile Agency.
@playdeltav.bsky.social68 years ago today: NASA opens.
NASA began operations, absorbing the National Advisory Committee for Aeronautics and about eight thousand staff. 17 orbital launches have flown on this date.

@spaceflightpedia.comChang'e 2 flew past asteroid Toutatis at just 3.2 km. Launched 16 years ago today, on 1 October 2010, to map the Moon, it left lunar orbit on 8 June 2011, reached Earth–Sun L2, then passed Toutatis on 13 December 2012 at 10.73 km/s.
@spaceflightpedia.comA stuck thruster spun Gemini 8 at 296 degrees per second. On March 16, 1966, Neil Armstrong and David Scott had just made the first docking of two spacecraft in orbit. Stopping the spin used almost 75% of the reentry maneuvering fuel. The mission was cut short.
