Sunita Williams Ventured on 7th Space Walk

Indian American astronaut Sunita Williams along with a fellow astronaut moved out of the International Space Station on 1 November 2012.
The Expedition Commander Williams and Aki Hoshide, Flight Engineer switched their space suits to batter power showing the start of the planned 6.5 hours excursion outside the Space Station.
The NASA statement mentioned that while the astronauts took their walk they ventured out to the port side of the station's truss to configure the 2B solar array power channel's photovoltaic thermal control system (PVTCS) to support ground-based troubleshooting of an ammonia leak.
Over the period of time , flight controllers at Mission Control Houston will check periodically if the leak continues.
This was the seventh spacewalk for Indian astronaut Sunita Williams who holds the record for spacewalking time with over forty four hours during six previous excursions.
This was the third spacewalk for Hoshide, who holds the equivalent record for Japanese astronauts. This is the 166th spacewalk in support of International Space Station assembly and maintenance and also the 138th spacewalk from the station.
