NASA’s Space Shuttle tiles, primarily the LI-900 silica tiles, are made from nearly pure quartz sand and can withstand temperatures up to 2,300 degrees Fahrenheit. Despite being red hot, these tiles are such poor heat conductors that they can be held by the edges without burning. This advanced material prevents heat transfer to the shuttle’s aluminum skin, ensuring the safety of the structure and crew during re-entry. These tiles are crucial for space missions, as they protect the shuttle from t

The Space Shuttle was protected during reentry by its thermal protection system tiles, and it glided as a spaceplane to a runway landing, usually to the Shuttle Landing Facility at KSC, Florida, or to Rogers Dry Lake in Edwards Air Force Base, California. It had a glide ratio of 4.5:1, which is only slightly better than a helicopter with an engine failure (4:1) | Airline Secrets Exposed
