Spacesuits | HOW IT'S MADE
ronauts from decompressing in an orbiting spacecraft. However, it is impossible to wear these suits for spacewalks because they cannot withstand the harsh space environment. These suits consist of five layers. The layer closest to the body is white cotton underwear with accessories for biomedical equipment.

Next is the blue nylon layer that provides comfort. On top of the blue nylon, this layer is a pressurized black neoprene coated nylon layer. This stores oxygen in the matter of cabin pressure breakdown. The next layer of PTFE maintains the shape of the suit when pressurized, and the last layer is white nylon material to reflect sunlight and prevent accidental damage.

During the first spacewalk during ,the Gemini mission in 1965 a sevenlayer space suit was used to provide additional protection. The additional layer is composed of aluminized polyester film, which provides more thermal protection and micrometeoroid protection.

The total weight of these protective clothing is 33 lbs. Although they are sufficient, there are some problems associated with them. For example, the mask on the helmet quickly fogs up, which hinders vision. In addition, the gas cooling system is not sufficient because it cannot remove excessive heat and moisture quickly enough.

Sally Ride is best known for being the first American woman to be sent into outer space. As a scientist and professor, she served as a researcher at the International Security and Arms Control Center of Stanford University, a member of Apple Computer's board of directors, and a director of the Institute of Space Research and a professor of physics at the University of California. San Diego. This cycling choice is mainly for children to write articles about space travel and exploration.

Sally Kristen Ride is Dale Burdell and Carol Joyce Ride of Encino, California the eldest daughter was born on May 26, 1951. As the author Karen O'Connor described in her book "Sally Ride and the New" by young readers, the tomboy Ryder. When she was only 5 years old, she participated in the sports section of the newspaper with her father.

As an active, adventurous but also educated family, when Sally was 9 years old and her sister Karen was 7 years old, Reid One family travelled in Europe for a year.

Although Karen was inspired to become a pastor, in the spirit of her parents, Ride's own evolving taste for exploration eventually made her apply for the space program almost on a whim. "I don't know why I did this," she confessed to Newsweek before starting her first space flight.

Since the year she started her job search was the first time NASA opened its space program to job seekers since the late 1960s, this opportunity was accidental, and it was the first time that women would not be excluded from consideration.

This flight became one of 35 people selected from 8000 applicants in 1978. "Why I was selected is still a mystery," she later admitted to John Grossman in a health interview in 1985 stating "None of us has been told."

Subsequently, at the age of 31, this trip will be the youngest person to be sent into orbit, the first American woman to enter space, the first American woman to fly twice in space, and coincidentally, The first astronaut to marry another active astronaut. responsibility.

However, Ryder left NASA in 1987 for the International Security and Arms Control Center at Stanford University. Two years later, she became the director of the California Institute for Space Research and a professor of physics at the University of California, San Diego.

The Apollo mission uses a more complex suit to solve some of these problems. During the moonwalk, the astronaut wore a sevenlayered suit with a life support backpack. The total weight is approximately 57 lbs (26 kg). For the space shuttle mission, NASA introduced an extravehicular manoeuvre unit (EMU).
