16. Q: What makes NASA Ames' Arc Jet Facility unique and important for NASA's future missions?
Balboni: For all spacecraft, that enter an atmosphere, whether that be Earth or another planets or moons, the spacecraft must have a heat shield to protect it from the severe environment. And that heat shield then has to be tested before it's flown. The only means of testing it is in what's called an arc jet facility. And, so, the arc jet facility, then, supports not only the Space Shuttle and any other, ah, missions to and from Earth and the Space Station, but also all of the planetary science missions, whether that be to Mars or the outer planets, ah, the arc jet facilities provide the testing that is required to design a heat shield to make that spacecraft survive the mission.
