NASA is set to launch the first all-female spacewalk Friday, after canceling it earlier this year because it does not have two spacesuits in the right size. NASA astronaut

it was planned to be the first all-female walk, but the plans were canceled when NASA said no spacesuit was available in Ms. McClain’s size. Ms. Mcclaines’s space mission ended this summer and she returned to Earth, but in September, Ms. Meir arrived at the International space station, joining Ms. Koch as the only woman on Board. Ms. Meir is now scheduled to join Ms. Koch on a spacewalk, NASA said.

Ms. Koch and Ms. Meir spoke on a video from the space station shown at a NASA media event previewing spacewalks with reporters. We don’t even think about it on a daily basis. Its just fine. Were part of the team. It’s great to see how far we’ve come, Ms. Meir said of her approaching all women milestone.

Ms. Koch, who arrived at the space station on March 14, is also on track to set the record for the longest flight by a woman into single space. Currently scheduled to be in orbit for 328 days, it will Eclipse a former NASA astronaut

A properly fitting spacesuit is key to providing the range of motion needed to perform work – related spacewalk missions, according to NASA. Spacesuits, or Extravehicular Mobility Units, weigh between 350 and 500 pounds depending on equipment and provide air and temperature control, battery power, communications and protection from radiation and space debris.

On October 6, Ms. Koch and his fellow NASA astronaut

Andrew Morgan

completed the first of five spacewalks scheduled for this month of a seven-hour, one-minute operation to replace Nickel-hydrogen batteries with newer, more powerful lithium-ion ones on the outside of the International space station. On October 11, Ms. Koch and Mr. Morgan completed a six-hour and 45-minute spacewalk to continue work on the batteries.

Ms. Koch and Ms. Meir were originally scheduled to perform a walk on October 21 to do battery upgrades, but instead set to replace the faulty power supply. The failure of the units does not affect crew safety or ongoing laboratory experiments, but prevents a new lithium-ion battery installed earlier this month from providing additional power to the station, according to NASA.

More spacewalks intend to follow those to recover the alpha Magnetic spectrometer, a cosmic ray spectacle searching for evidence of dark matter in the Universe.

Since its inception in 1958, NASA has selected 350 astronaut candidates, 57 of whom were women. Currently, out of 38 active astronauts and 11 candidates for training, 17 are women. A total of 65 women flew in space, including women from France, Canada, the UK, Iran, Korea, Japan, China and Italy.

NASA also plans to send the first woman to the moon by 2024. On Tuesday, the Agency unveiled prototypes of the spacesuit that will be used on this mission. Engineer SKA on savastru
