The first spacewalk outside the shuttle during the STS-6 mission

On April 7, 1983, astronauts performed the first spacewalk outside of a space shuttle during the STS-6 mission.


This mission is the first trip of astronauts with Challenger space shuttle Was. Satellite carrier shuttle TDSR-1 was relaying and intercepting the data path.

The STS-6 mission was delayed once due to a hydrogen leak from Challenger’s main engines, and after it was repaired, a severe storm contaminated the target satellite. Therefore, after checking the correctness of the satellite and shuttle operation, Challenger was launched on April 4, 1983 at 13:30 local time.

STS-6 had four passengers including Paul Weitz (flight commander), Carol Babko (pilot), Donald Peterson (mission specialist) and The Musgrave Story (astronaut)

This mission ended on April 9 with the shuttle landing at Edwards Air Base. The shuttle orbited the earth 80 times and traveled more than 3 million kilometers in space in 4 days, 23 minutes and 42 seconds.

The first march outside the shuttle

Musgrave and Peterson made a four-hour, 10-minute walk that lasted from 9:05 p.m. on April 7 to 1:15 a.m. on April 8.

The 2,500 kg TDSR satellite was successfully launched into space by Challenger, but the satellite’s two-stage thrusters failed to lift it into upper atmospheric orbit.

With the help of propulsion engines, within a few months, TDSR reached the geosynchronous orbit and the $100 million satellite was saved.
