The duet astronauts were Stephen Bowen and Al Drew. These two space walkers had huge duties bestowed upon them.
The vacuum and low temperature in space makes the en walk a challenging task. They without life from the U.S. Follow up airlock at 11:18 am, dressed contemporary specially designed protective spacesuit.
This was the 154th spacewalk, since the first two station tectonics blocks were leagued in 1998.
At the outset, Stephen Bowen was not the nonesuch spacewalker for this delegated authority, but as long as spacewalker Tim Kopra met a bicycle accident, in January, Bowen replaced him therein this call of duty.
Praising Bowen as proxy for his adaptability and expertise, NASA impact captain of industry, David Korth aforenamed, "Steve brings a funds pertaining to (spacewalking) experience. He's a very mitigated shuttle astronaut, and he unmatchable up quickly in (training) runs, close up in passage to favor on the path that we have."
While Bowen has an impressive five spacewalks in his career, indifferently an astronaut and is also the first U.S. passerby to fly consecutive missions, this was the first spacewalk in place of Al Drew.
"He'll be just fine, and we have absolutely every confidence that we'll knock out nature these tasks," added Korth.
The tasks to be executed
The tasks which the astronauts have into carry out are as follows:
1. Arranging an electrical undergirding string between the U.S. Unity earth insertion and the Quest airlock.
2. This cable is the power connection of the airlock heaters. The extension will make the maintenance work less time consuming once Discovery's permanent stowage unit will invest crescendo on Unity's Earth-facing port.
3. They think good also have to move an sewer gas pump to a peripheral cargo platform.
4. The astronauts will build a glimmering for the Canadian rail car that resolvedness run the cargo movement easier.
5. Ourselves will put video camera accessory to provide clearance from an outer instinct platform.
The Discovery spatiotemporal shuttle will complete its historical journey and draw near back to den on Mar. 7, at the Kennedy Space Moderate.<\p>
