Narrator: This spacesuit, built in 1974, was reported to cost between $15 million and $22 million. Today, that would be about $150 million. Having not delivered any new mission-ready extravehicular suits since then, NASA is running out of spacesuits. In fact, NASA are down to just four flight-ready EVA suits.
What does a spacesuit do?
A spacesuit protects astronauts from those extreme temperatures. Spacesuits supply astronauts with oxygen to breathe while they are in the vacuum of space. The suits contain water to drink during spacewalks. They protect astronauts from being injured from impacts of small bits of space dust.
What is the name of the suit that astronauts wear?
The formal name for the spacesuit used on the space shuttle and International Space Station is the Extravehicular Mobility Unit, or EMU. "Extravehicular" means outside of the vehicle or spacecraft. "Mobility" means that the astronaut can move around in the suit.

How do spacesuits keep you warm?
"In space, it's a matter of insulation. Just as your blanket keeps your body heat in so you stay warm in bed, NASA space suits have insulation systems as well as heaters." When a person's body temperature rises, the material absorbs the heat. When it drops, the material gives off the heat, providing warmth.
How much does a NASA spacesuit cost in 2021?

How do humans get oxygen in space?
The short answer is the astronauts and cosmonauts (that means a Russian astronaut) bring oxygen from Earth, and they make oxygen by running electricity through water. This is called electrolysis. Astronauts and cosmonauts also receive supplies from uncrewed spaceships, such as the Russian Progress and American Dragon.
How did gold get on Earth?
All of the gold found on Earth came from the debris of dead stars. As the Earth formed, heavy elements such as iron and gold sank toward the planet's core. If no other event had occurred, there would be no gold in the Earth's crust. But, around 4 billion years ago, Earth was bombarded by asteroid impacts.
