Space blanket floats away during spacewalk

MIAMI: A space blanket floated away from American astronaut Peggy Whitson on Thursday as she made a historic spacewalk outside the International Space Station, setting a new record for the most spacewalks by a woman.

The crew was not in danger due to the mishap, which occurred when Whitson was trying to fold up a bulky cloth cover, known as an axial shield, and put it in a bag.

The incident briefly raised concern at mission control in Houston that the shield might come back and hit the orbiting laboratory.

About four hours into the spacewalk, however, Nasa determined that the gear had drifted a safe distance away and there was “no recontact risk,” said Nasa commentator Gary Jordan.

Images on Nasa television showed the shield as a small white dot in the darkness. A statement on Nasa´s website said the shield “was inadvertently lost” and “posed no immediate danger to the astronauts”.

The space blanket was one of four covers designed to guard the station from micrometeoroids, and also for thermal protection. 

The spacewalk formally began at 7:29 am (1129 GMT) when Whitson and Kimbrough switched their spacesuits to battery power before venturing outside the airlock and into the vacuum of space.

“Be safe and enjoy your time out,” said French astronaut Thomas Pesquet as the hatch opened and Whitson made her way out in the dark, her path illuminated by a light on her helmet.

“I will be waiting for you.”

For Whitson, 57, the seven-hour, four-minute spacewalk was the eighth of her career, surpassing the record of seven previously held by US astronaut Sunita Williams.

During the walkabout, Whitson also beat Williams´s time spent spacewalking. Williams´s record was 50 hours 40 minutes. Whitson´s total time is now 53 hours and 25 minutes.

“This is a significant milestone,” said Jordan, as Whitson became the world´s most experienced female spacewalker.

“Congratulations to Peggy Whitson.”

The goal of the spacewalk was to continue upgrading the International Space Station for the arrival of commercial spaceships in the years to come.

SpaceX and Boeing are currently designing crew vehicles that will begin flying people to the ISS as early as next year.

Whitson earned a doctorate in biochemistry and served as the first female space station commander in 2008.

She is a native of Iowa and is known for her quick wit, sense of humor and ease in communicating complicated science topics to a lay audience.
