[The Martian] What changes did NASA make to the Ares Missions after Mark Watney's safe return? How did his time on Mars impact the program as a whole?

I don't think it really did. A lot of Watney's experiences validated many original design choices, such as pre-deployment of the MAV, and demonstrated considerable reserve capacity in NASA's equipment. Not to mention the scenario Watney got caught in is exceedingly improbable, so improbable that any precautions are just likely to *increase* risk.
