[The Martian by Andy Weir] in the aftermath of the events of the book. What policy/ methodology changes would be introduced?
gpt
(1) A secondary communication system able to reach the orbiter to relay to Earth buried on the site as an emergency backup.

(2) Enough food cached to keep the crew alive until a rescue mission could get there.  Probably sent with the MAV but you could also keep it in orbit so you only have to send teh cache once and its an emergency supply for multiple missions.  MMM high density nutritional gel.  

(3) Better weather satellites to detect dust storms earlier.

(4) Bigger media library to keep the disco from driving you mad.

(5) If someone is presumed dead after an escape attempt stay in orbit for a while to make sure they are dead before heading back to Earth.
