Spacewalking astronaut loses mirror, newest space junk

Astronauts belonging to the NASA space agency concluded a six-hour long space walk on Friday for replacing batteries that provide power for the International Space Station's (ISS) solar arrays.

Astronaut Chris Cassidy (Chris Cassidy) lost mirror during a spacewalk to fix the ISS.

Wrist mirrors are used by astronauts to read displays and examine places that are not fully visible due to the limited view in a spacesuit.

The new lithium-ion batteries the men are replacing the old batteries with arrived at the International Space Station last month on a Japanese cargo ship. They have four more to plug in before the job is complete.

"I think we've done enough for one day", Behnken said.

As the spacewalk ended, Cassidy thanked the cleaning staff at Mission Control in Houston, kept especially busy during "this insane, interesting time".

In big and boxy sizes, these batteries must be powerful and efficient than the older batteries of nickel-hydrogen, so the station keeps humming when it is on the planet's night side.

These battery replacements started in 2017, with previous astronauts placing 18 batteries made from the lithium-ion compound. It's cumbersome work: Each battery is about a yard (meter) tall and wide, with a mass of 400 pounds (180 kilograms).

Behnken and Doug Hurley made history when they set off towards the ISS in a Space X Dragon capsule, marking the first-ever first human spaceflight through a government-private partnership.

Friday's spacewalk was the seventh for both astronauts. Each has committed 30 hours out in space's vacuum.

The two spacewalks will be the 228th and 229th in support of space station assembly, maintenance and upgrades, NASA said. The AP is exclusively responsible for all content.
