NASA Why? Files segment exploring how space suits work and how they are designed.
Hi Mr. Utley, I'm Bianca and this is Anthony.
00:00:00
Hi, it's nice to meet you both. I understand from Mr. Utley that you want to learn more about the spacesuits that astronauts wear.
00:00:07
Wow, do astronauts really have to wear all this stuff?
00:00:12
Yes, they do. The spacesuit protects the astronauts from the extreme environment of space.
00:00:15
We know they need a spacesuit for oxygen, but what else does it protect them from?
00:00:19
It protects them from things like extreme temperatures, very small meteoroids, orbital debris, and radiation.
00:00:23
Wow, I didn't know space was so dangerous.
00:00:29
The spacesuit looks big.
00:00:32
It is big, and when an astronaut wears it, it inflates like a balloon to make it even larger.
00:00:34
Why does it inflate?
00:00:38
In space, there's no air pressure, and without air pressure, the astronauts' blood would boil.
00:00:40
That doesn't sound good.
00:00:44
No, it's not. So the spacesuit provides the air pressure the body needs to keep that from happening.
00:00:45
What are these?
00:00:50
These are the astronauts' long johns. They keep the astronaut cool while he or she works in space.
00:00:51
How does it do that?
00:00:55
They're little tubes woven into the long johns. Water flows through the tubes, keeping the astronauts cool.
00:00:57
There are some days I wish I had one of these.
00:01:01
Is that what I think it is?
00:01:04
Yes, it is. It's called a mag for maximum absorbency garment.
00:01:06
Do astronauts really have to wear that?
00:01:10
Yes, spacewalks can last up to eight hours, and that's a long time to go without a bathroom break.
00:01:12
That's for sure. I couldn't go that long.
00:01:17
Neither can the astronauts, and they are working with billions of dollars of equipment.
00:01:19
They need to be able to concentrate in order to do their job correctly.
00:01:23
And you can't concentrate if you have to go to the bathroom.
00:01:26
Do you make these spacesuits, Ms. Ross?
00:01:29
No, NASA hires a company to actually make the spacesuits.
00:01:31
My primary job is to test and evaluate the suits so that I can design better spacesuits.
00:01:34
We learned all about that from our invention contest. It's called the iterative process.
00:01:38
It sounds like you've tested, evaluated data, and redesigned yourselves.
00:01:42
Do astronauts have to wear different suits for different jobs?
00:01:46
Sometimes. For example, Joe Cosmo and I worked with a company called ILC to build a better spacesuit glove.
00:01:49
Why did they need a better glove?
00:01:55
To build the space station. The glove was a phase six, and I made sure it was ready to use in space.
00:01:57
Did it really work?
00:02:01
Yes, it did. The glove was used on the first American space station construction mission, STS-88.
00:02:02
That is so cool to know that you actually helped the astronauts build the space station.
00:02:07
I might do that someday.
00:02:12
Yes, you might. Keep up the hard work.
00:02:13
Thanks, Ms. Drives. We learned a lot.
00:02:15
You're welcome, and good luck on your Martian habitats.
00:02:17
Thanks. Bye.
00:02:19
Bye.
