March 20 in Universe History: Space Missions, Astronomy and Exploration
March 20, 2026
1982
On March 20, 1982, astronauts Jack R. Lousma and C. Gordon Fullerton arrived at NASA’s Kennedy Space Center to prepare for STS-3 through mission reviews and Shuttle Training Aircraft landings. Their arrival came mid-countdown and set up a March 22 launch of Columbia, enabling continued thermal characterization and early Remote Manipulator System operations in flight.
1996
On March 20, 1996, the first launch attempt for Space Shuttle Atlantis mission STS-76 was scrubbed before cryogenic tanking began because of high-wind concerns at Kennedy Space Center. Managers then recycled the countdown and launched successfully on March 22, enabling the third Shuttle–Mir docking and transfer of astronaut Shannon Lucid for a long-duration stay aboard Mir.
2026
On March 20, 2026, NASA’s Artemis II Space Launch System rocket and Orion spacecraft arrived at Launch Pad 39B at Kennedy Space Center after crawler-transporter rollout from the Vehicle Assembly Building, positioning the first crewed Artemis stack for pad-level checkouts, systems verification, and launch-readiness work for a four-astronaut lunar flyby.
