Video: NASA officials preview space station battery replacement spacewalks

Legendary cosmonaut Alexei Leonov, the first human to walk in space — an experience that almost killed him — and later the commander of the Russian Soyuz spacecraft that docked with a NASA Apollo capsule, symbolizing a historic thaw in the Cold War, has died after a long illness, the Russian space agency confirmed Friday. He was 85.

The three newest residents of the International Space Station sped into orbit Wednesday aboard a Soyuz launcher after liftoff into an overcast sky over the Baikonur Cosmodrome in Kazakhstan. These photos show the crew putting on their spacesuits and their mid-afternoon launch.

Astronauts Steve Bowen and Woody Hoburg suited up and floated outside the International Space Station Friday for a spacewalk to install and unroll an upgraded solar array wing delivered to the complex earlier this week by a SpaceX Cargo Dragon supply ship.
