[i]SNC's Dream Chaser spacecraft looks a little different these days. We now have more white Thermal Protection System tiles than black. Aside from protecting Dream Chaser against high re-entry temps, they'll protect against an impact from space junk moving faster than 20,000 mph. The materials that make up Dream Chaser spacecraft's Thermal Protection System tiles can survive temperatures up to 3,200F while maintaining the underlying structure temperature below 350F, protecting the spacecraft from re-entry heat.[/i]
