Power Upgrade Spacewalks.
He performed two Spacewalks as part of a busy mission.
Of the 217 astronauts who have ever done Spacewalks, only 13 have been women.
Space suits for Spacewalks require lengthy
and costly development that can cost hundreds of millions of dollars.
Furthermore, Spacewalks are highly choreographed
and practiced several times in simulated conditions before an astronaut actually goes into space.
In the nearly 60 years of spaceflight, there have only been four times when
expeditions included two female members trained for Spacewalks.
The two suits on the International
Space Station that are currently calibrated for Spacewalks are a size medium- the smallest size- and a size large.
Two NASA astronauts are now outside the
International Space Station on the second of several planned Spacewalks to replace batteries affixed to the outside of the spacecraft.
In the news conference, Cassidy said there have been no real
changes to how astronauts are trained for Spacewalks since he arrived as a rookie astronaut in 2004.
NASA initially targeted Koch and Meir for an extravehicular activity on Oct. 21,
as part of a series of Spacewalks designed to install new batteries on the space station's exterior.
On the one hand, it shows that NASA is proud of the fact that there
were two women in space at the same time who are both capable of doing Spacewalks.
US Astronauts Complete 1st of 5 Power Upgrade Spacewalks- Two NASA Astronauts have successfully
wrapped up a seven-hour and one minute Spacewalks, marking the completion of the first of the five Spacewalks to upgrade the station's power systems this month.
