A traditional Japanese pottery and toy manufacturer Tamiya have joined forces
to develop heat-dissipating tiles for HOPE, Japan鈥檚 uncrewed space shuttle. The
tiles are made of a natural stone and polystyrene foam, fired in a kiln for
several days. Their relative density is about half that of the tiles used in the
American space shuttle, and their melting point of 1700 掳C is 200 掳C
higher. HOPE is due to launch in 2003.
