It's going to hit the atmosphere at 3000 mph. That would strip the chrome right off the front bumper of my Chevy.
During reentry the vehicle reaches its peak speed of about Mach 3. However, due to the low dynamic pressures on the spacecraft, the vehicle never exceeds an “equivalent” airspeed of 285 kmph. The heating on the spacecraft is also limited during reentry—the stagnation temperature at peak heating is just under 600°C—meaning the spacecraft needs only a limited thermal protection system (TPS). “We have designed the structure so that the crew is not in jeopardy if the TPS fails,” Rutan said, although he added that the vehicle would require repairs if the TPS failed.
