Forget about the wonders of space and the philosophical implications of seeing Earth as a blue dot in a star-filled black sky. Astronaut Mark Watney, the lead character in "The Martian," a book by Andy Weir, is more concerned about staying alive, and for that there's nothing like good old-fashioned engineering and technical know-how.
Which is why NASA is so excited about the upcoming debut of a film by the same name, starring Matt Damon and directed by Ridley Scott.
Without giving away too much, the story revolves around Watney's trials and tribulations soloing on Mars after he is inadvertently left by his evacuating crewmates.
The U.S. space agency, which is slowly moving toward a mid-2030s human expedition to Mars, is eager to connect the dots between its ongoing development efforts and engineering finesse the fictional Watney employs to boost his chances of survival.
Here is a look at some Mars technologies currently under development.
