They identify the tiles. They all have specific spots they must be attached. The numbers correspond to those spots.
The cost of the Space Shuttle heat shield tiles varied depending on factors such as the type of tile, quantity needed, and manufacturing processes. Overall, the heat shield system for the Space Shuttle program was estimated to have cost several hundred million dollars.
The Space Shuttle Columbia, on which Kalpana Chawla was a member of the crew, disintegrated upon re-entry into the Earth's atmosphere on February 1, 2003. A breach in the shuttle's thermal protection system caused by damage to the shuttle's wing during launch led to the tragedy.
Mathematically:where:ρ (rho) is the density, m is the mass, V is the volume.ρ = 150/75 = 2 g/mL
The black tiles underneath the space shuttle are made of ceramics. Ceramics are already fired and thus able to withstand very high temperatures. The ceramic tiles do oxidize (which means material is lost) and are replaced between missions. The failure on Columbia was due to some of those ceramic tiles having fallen off during take off.
Columbia & Challenger had approx 32,000 silica tiles glued to them and as Discovery, Atlantis & Endeavor were being built, high temp resistant cloth were used to lighten the weight of the vehicles and to make replacing the thermal protection of the shuttle much easier. The last 3 shuttles had 20,000 to 22,000 tiles on them, with each tile being hand shaped with a saw, then cured in an oven and then hand glued to the the shuttle.
