His background in botany and engineering becomes practical as he rations supplies and repairs equipment.

Watney records problems with humor, making technical setbacks part of his voice as well as the plot.

NASA and the crew face their own constraints while trying to determine whether rescue is possible.

The novel makes scientific problem-solving entertaining, though its imagined mission details and rescue scenario remain fiction.
