Zee Media Bureau
New Delhi: NASA on Wednesday will conduct its second out of the three complicated spacewalks at the International Space Station.
NASA TV will cover the walk showing it live beginning Wednesday at 6 am EST (1100 GMT).
Astronauts Barry Wilmore and Terry Virts undertook the first spacewalk on February 21. The 6-hour, 41-minute-spacewalk from Expedition 42 of astronauts Barry Wilmore and Terry Virts was meant to prepare the ISS for a pair of international docking adapters (IDAs) that will allow future commercial crew vehicles to dock.
The third spacewalk is planned to take place on March 1.
The job of all the three spacewalks is to prepare the space station for the arrival as early as 2017 of US commercial crew capsules bringing astronauts to low-Earth orbit for the first time since the 2011 end of the space shuttle program.
NASA has awarded contracts to Boeing and SpaceX to develop, test and fly capsules that can taxi astronauts to and from the station.
According to SpaceX, the upgraded Dragon V2 passenger spacecraft should be ready for an unmanned debut test flight to the station in late 2016 and a crewed test flight in early 2017.
Boeing plans is to dock an unmanned CST-100 test flight to the station in April 2017.
