Russian cosmonauts Alexander Skvortsov and Oleg Artemyev completed a 5-hour, 11-minute spacewalk Monday, launching a Peruvian nanosatellite and installing and retrieving various science experiments from the International Space Station's exterior.
The tiny Chasqui-1 satellite measures just 4 inches by 4 inches by 4 inches and weighs only 2.2 pounds. According to NASA,
"Shortly after the spacewalk began at 10:02 a.m., Artemyev manually deployed Chasqui 1, a Peruvian nanosatellite designed to take pictures of the Earth with a pair of cameras and transmit the images to a ground station. The project is part of an effort by the National University of Engineering in Peru to gain experience in satellite technology and emerging information and communication technologies."
While spacewalks may seem routine these days, an extra-vehicular activity is still the most dangerous activity an astronaut can do in space... and spacewalks of the future could get even more menacing. Tonight on "Man vs. the Universe" (10/9c), learn about scientists' efforts to stop an asteroid from crashing into Earth. One method calls for catching an impending asteroid in a giant bag, then sending astronauts on the most dangerous spacewalk ever.
