OTD…June 3, 1965 and the first American walk in space

NASA’s first space station — the Skylab orbital workshop — was launched atop a Saturn 5 rocket today, May 14, in 1973.

Now in the home stretch of a complex, multi-year upgrade, two space station astronauts floated outside the lab complex Thursday and pressed ahead with the third of four spacewalks the current crew is carrying out to complete the replacement of aging batteries in the station’s solar power system.
