Thoroughout his stay on Mars, Watney keeps an extensive collection of video logs of his activities using the various cameras at his disposal. The Hab and Rover also have continuous monitoring systems. In the movie version, we often see the action from the perspective of these recording devices.

What happens to all this data at the end of the story? Did NASA receive it? Mark couldn't have physically taken it with him on the MAV, since he needed to reduce his weight as much as possible. (Unless his spacesuit has some kind of built-in data storage. Even then, he's never seen downloading the videos, or interacting with the data at all, really.)

His communication with NASA while on Mars happens via a makeshift setup using the Mars probe as a relay. It doesn't seem like it would have the bandwidth to continually upload the video feed, not to mention it's highly unlikely the process could be automated.

Supporting the above point, the movie consistently avoids showing NASA as seeing those videos during the events of the story. All they are going on is satellite imagery, text chat, and the occasional Pathfinder camera image.

Did the video logs reach Earth eventually? Or were they all left behind on Mars?
