Washington DC, Aug 6 (THAINDIAN NEWS) NASA has scheduled two spacewalks to repair its failed ammonia pump on the International Space Station.

The first spacewalk has been moved to this Saturday, while the next spacewalk has been fixed at Wednesday, i.e. the 11th of August. The space agency said that the astronauts would use the spacewalks to complete the repairs on the failed ammonia pump.

NASA says the event which will be broadcast on NASA Television is in advanced stage. The agency says its astronauts, flight controllers and spacewalk experts are ready for the trip. But the agency maintains that it needs another day to be fully prepared for the mission. The agency say the extra day will help them to send the final procedures to the space station.

NASA says Expedition 24 Flight Engineers Tracy Caldwell Dyson and Doug Wheelock are tasked with the spacewalk expedition. The agency says the broadcast of the event will start at 5 am CDT. The actual spacewalk is scheduled to begin 55 minutes after the start of the coverage.

It ought to be mentioned that astronaut Wheelock is an experienced space walker. This will be his fourth spacewalk while astronaut Caldwell would be having his first spacewalk.

The failure of the ammonia pump on July 31 caused the loss of two cooling loops on board the station. The failure caused the station to lose power but NASA says the station’s systems are stable now.
