I also got stuck about halfway through digging out the pit for the Geology photos. I appeared to just be standing on the surface, but couldn't walk, place blocks or drill. The jetpack made noise but did not move me. Saving the game and re-entering the game did not help.

I was able to recover by exiting the app (press Home button), bringing up the iOS task manager (press the Home button two times fast), then kill the app (touch and hold the app's icon until a red "-" badge appears on it, then tap the red "-" badge to make the app icon go away. This is NOT deleting the app, which is a black "x" badge and brings up a "Delete" confirmation warning). After killing the app I re-started it, and I was able to walk, jump, drill and place blocks.
