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

Expedition 45 commander Scott Kelly and flight engineer Kjell Lindgren have switched their spacesuits to battery power to begin planned six-and-a-half-hour spacewalk Wednesday outside the International Space Station.

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.
