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

#OTD…Launch of Atlantis in 1989 to send the Magellan space probe to Venus

Two Russian cosmonauts used the International Space Station’s Poisk docking compartment as an airlock for the first time Wednesday in a six-hour 48-minute spacewalk to begin preparing the nearly identical Pirs module for removal next year. A new laboratory module will be parked in its place later.

The grapple mechanism installed on one end of the space station’s robot arm during a spacewalk Tuesday is experiencing problems. It will be removed during a re-planned spacewalk Monday and the original fitting will be re-installed, NASA said Friday.
