- Sorry if this has already been answered. I've been out of commission for a

- The orbiter's thermal protection system is composed of four different types
- of insulation: reinforced carbon-carbon, high and low-temperature reusable
- surface insulation (white & black tiles), and nomex felt.
-
- o Reinforced carbon-carbon [RCC] covers the nosecap an the leading edges of
- the orbiter's wings. It is light grey in color, and can withstand
- temperatures up to 3,000 degrees.

-
- o High and Low-Teperature Reusable Surface Insualtion [HRSI, LRSI] are the
- familiar 'tiles' on the surface of the orbiter. They are composed of
- 99.7% sand (!) which has been compressed in to silica fibers and added to
- a ceramic binder. The mixture is fired in a kiln and machined to form the
- blocks.
-
- The tiles are held in place by glass-creamic retainers (made by Corning)
- but are not in direct contact with the orbiter's aluminum skin. Instead,
- Nomex pads are sandwiched in-between to allow for airframe flexing
- during descent (same maker as FRSI).
-
- HRSI tiles are black, and can withstand temperatures up to 2,300 degrees.
- LRSI tiles are white, and can withstand temperatures up to 1,200 degrees.

-
- o Nomex felt [FRSI] covers the portion of the orbiter's skin which remain
- coolest during descent. Challenger used the FRSI more extensively than
- Colombia, replacing some of the LRSI tiles. Nomex replaced all of the
- LRSI tiles on Discovery and Atlantis.
-
- FRSI is white, and can withstand temperatures up to 700 degrees.
