The lightweight tiles protect the shuttles from extreme temperatures when the orbiters re-enter the Earth's atmosphere. Schools can request a tile at: http://gsaxcess.gov/NASAWel.htm
Click on the tile icon to log on to the request page. A login ID and password may be obtained by registering on the link provided. A Department of Education statistics tracking number (NCES for schools or IPEDS for universities) is needed to register. The requests will be filled on a first-come, first-served basis. Only one tile will be given per institution.
Because the tiles are government property, a transfer protocol is observed. Recipients will be responsible for a shipping and handling fee of $23.40, which is payable to the shipping company through a secure website.
