Astronaut Scott Kelly posted this photo to Twitter on August 9, 2015 with the caption, “Day 135. #MilkyWay. You’re old, dusty, gassy and warped. But beautiful. Good night from @space_station! #YearInSpace”.

NASA astronauts Scott Kelly and Kjell Lindgren switched their spacesuits to battery power at 6:22 a.m. EST, signifying the start of today’s spacewalk, planned for 6 hours and 30 minutes.

Lindgren is wearing a spacesuit with red stripes and is designated EV1. His helmet camera displays the number 17. Kelly is wearing a spacesuit with no stripes and is designated EV2. His helmet camera displays the number 18.

The astronauts are embarking on the 190th spacewalk in support of space station assembly and maintenance to restore the port truss ammonia cooling system to its original configuration following a leak detection exercise three years ago that ultimately resulted in the replacement of an ammonia pump on the station’s truss.

NASA Television is broadcasting the spacewalk at www.nasa.gov/nasatv.
