Two Astronauts Spacewalk Outside Station

CAPE CANAVERAL, Fla., Aug. 7 (UPI) — Two U.S. astronauts exited the International Space Station on schedule Saturday and got to work on fixing the station’s cooling system, NASA confirmed.

A heavy ammonia pump that conked out a week ago will be removed and replaced with a spare module from an external storage compartment.


Flight Engineers Doug Wheelock and Tracy Caldwell Dyson left the station and switched their spacesuits to battery power around 7:19 a.m. EDT, NASA said in a written statement. They were to spend between 6 ½ to 7 hours in space Saturday and another six hours on Wednesday.

The mission had been scheduled to begin Friday, however mission controllers decided more preparation time was needed and moved it to the weekend.

NASA said this was Wheelock’s fourth space walk and the first for Caldwell Dyson.
