As discussed in the video, the leading hypothesis for why Mars changed holds that interior cooling led to loss of its magnetosphere, allowing the solar wind to strip atmospheric gas away. How has the MAVEN mission provided evidence for this hypothesis?
a. It has measured rates of gas loss from the atmosphere today.
b. It has measured the rate at which Mars’s interior has lost heat.
c. It measured the amount of atmospheric gas that Mars had long ago.
d. It has measured the strength of the magnetic field that Mars had long ago.
Ans: a. It has measured rates of gas loss from the atmosphere today.
