First Atlantis flight

Space Shuttle Atlantis (Orbiter Vehicle designation: OV‑104) is a retired Space Shuttle orbiter vehicle which belongs to NASA, the spaceflight and space exploration agency of the United States.^[1] Atlantis was manufactured by the Rockwell International company in Southern California and was delivered to the Kennedy Space Center in Eastern Florida in April 1985. Atlantis is also the fourth operational and the second-to-last Space Shuttle built.^[2]^[3] Its maiden flight was STS-51-J made from October 3 to 7, 1985.

EVAs

Start Date/Time	Duration	End Time	Spacecraft	Crew	Remarks
16 April	3 hours 6 minutes		STS-51-D Discovery	Jeffrey A. Hoffman S. David Griggs	Installed an improvised switch-pulling tool, called the Flyswatter, on the RMS robotic arm. The Flyswatter was used in an effort to push the sequencer start lever on the Leasat-3 in the proper position for deployment.^[4] This attempted repair was the first unplanned spacewalk in NASA history.^[5]
2 August 07:15	5 hours	12:15	Salyut 7 EO-4	Vladimir Dzhanibekov Viktor Savinykh	Installed a third pair of solar arrays on exterior of Salyut 7.
31 August	7 hours 20 minutes		STS-51-I Discovery	William Fisher James van Hoften	Van Hoften rode the RMS to capture the Leasat 3 satellite and pulled it into payload bay. Fisher and Van Hoften secured and started repairs on the satellite in the payload bay. The retrieval was complicated by a malfunction of the RMS that made operation of the arm more complicated.^[6]
1 September	4 hours 26 minutes		STS-51-I Discovery	William Fisher James van Hoften	Completed repairs on the Leasat 3 satellite. Then Van Hoften, riding the RMS, heaved the satellite out of the payload bay, imparting the required spin needed to fire the perigee motor.^[6]
29 November	5 hours 32 minutes		STS-61-B Atlantis	Jerry L. Ross Sherwood C. Spring	Practiced construction techniques in the payload bay and assembled and disassembled the two experimental EASE/ACCESS structures.^[7]
1 December	6 hours 41 minutes		STS-61-B Atlantis	Jerry L. Ross Sherwood C. Spring	Conducted supplementary experiments on the EASE and ACCESS structures, including a test of the RMS to aid in the construction experiments.^[7]
