Ceramics in space
- Can withstand temperatures from -150 to 1650 degrees C
- Invaluable in building spaceships
- Thermal protection systems that protect the spaceship and its occupants when it reenters the atmosphere of the earth.
With tougher ceramics, needle-nosed spacecraft like this NASA L1 concept, could reenter at higher speeds and ultimately less wear.
Spaceships such as the Rover Sojourner, which is coated in a solid silica aerogel, have used HRSI tiles with success.
