STS-73 Launch (1995)
October 20, 2015
Launched 20 years ago on this day, STS-73 was a 16-day mission flown by Space Shuttle Columbia and her crew of 7 astronauts. It was the second mission for the United States Microgravity Laboratory (Spacelab) and NASA maximized on-orbit research time by splitting the crew into two teams operating on opposite shifts.
Serving on his third spaceflight, Ken Bowersox commanded the mission. Kathryn Thornton served as a mission specialist; the mission was her fourth spaceflight. The 5 other crew members were all on their first spaceflight: pilot Kent Rominger (@Astro_Rommel), mission specialists Cady Coleman (@Astro_Cady) and Michael López-Alegría (@CommanderMLA), and Payload Specialists Fred Leslie and Albert Sacco Jr..
STS-73 is tied with STS-61C for having the most scrubbed launches — both missions did not launch until their seventh attempt.
