11. Q: When a spacecraft is entering Mars' thin atmosphere, which is at that planet's surface is about equivalent to Earth's atmosphere at 100,000 feet, how is the heat of entry on the spacecraft's surface different than the heat of re-entry into Earth's air?
Balboni: The fact that density of the atmosphere of Mars is much less than Earth, ah, as you say, the density of the atmosphere at the surface of Mars is equivalent to 100,000 feet on Earth. So, that does tend to lessen the heat to a spacecraft entering the atmosphere slightly, not a whole lot – not significantly. (22 SECONDS)
