Spacewalking astronauts face a wide variety of temperatures. In Earth orbit, conditions can be as cold as minus 250 degrees Fahrenheit. In the sunlight, they can be as hot as 250 degrees. A spacesuit protects astronauts from those extreme temperatures. This footage was taken by NASA astronaut Peggy Whitson during a spacewalk on the International Space Station on Thursday, March 30, 2017. She was joined on the spacewalk by NASA astronaut Shane Kimbrough. The two spacewalkers reconnected cables and electrical connections on PMA-3 at its new home on top of the Harmony module. They also installed the second of the two upgraded computer relay boxes on the station’s truss and installed shields and covers on PMA-3 and the now-vacant common berthing mechanism port on Tranquility.

Thx for follows and tips. A beautiful 1080p tour of our moon. It's so clear and beautiful you'll want to go there yourself. This virtual tour is based on data from NASA's Lunar Reconnaissance Orbiter. Enjoy this "new" Moon and its noteworthy destinations. Ancient peoples looked at the moon and saw in its patterns of shadow and light the figures of deities or animals. The Italian scientist, Galileo Galilei, trained his telescope on our celestial companion and saw mountains and valleys much like those on Earth.
