Astronauts Have Begun Spacewalk Live on NASA TV<\/h2>\n

<\/p>\n

\"NASA<\/a>
NASA astronaut and Expedition 63 Flight Engineer Bob Behnken works during a spacewalk to swap an aging nickel-hydrogen battery for a new lithium-ion battery on the International Space Station\u2019s Starboard-6 truss structure.<\/figcaption><\/figure>\n

NASA astronauts Robert Behnken<\/a> and Chris Cassidy<\/a> have begun the first of two final spacewalks to finish a 3.5-year effort to upgrade the International Space Station<\/a>\u2019s power system. They will replace batteries on one of two power channels on the station\u2019s far starboard truss (S6 Truss).<\/p>\n

The spacewalkers switched their spacesuits to battery power at 7:10 a.m. EDT to begin the spacewalk, which is expected to last between six and seven hours.<\/p>\n

Watch the spacewalk on NASA TV and on the\u00a0agency\u2019s website<\/a>.<\/p>\n

The spacewalkers will be removing five existing nickel-hydrogen batteries and replacing them with three new lithium-ion batteries that arrived on a\u00a0Japanese cargo ship<\/a>\u00a0last month. The batteries store electricity for one pair of the station\u2019s solar arrays, and the swap will upgrade the station\u2019s power supply capability. The batteries store power generated by the station\u2019s solar arrays to provide power to the microgravity laboratory when the station is not in sunlight as it circles Earth during orbital night.<\/p>\n

This is the\u00a0230th spacewalk<\/a>\u00a0in support of space station assembly and maintenance. Behnken is extravehicular crew member 1 (EV 1), wearing the spacesuit with red stripes, and using helmet camera #20. Cassidy is extravehicular crew member 2 (EV 2), wearing the spacesuit with no stripes and helmet camera #18. It is the ninth spacewalk for both astronauts.<\/p>\n
