People that get to do the same thing for a living as they did when they were a child are lucky. The ones that get to do it while wearing a space suit, too? They just make me jealous.

The guys in this image are testing space suits. In a sandpit. Hereā€™s a little more detail:

University of North Dakota graduate researcher Travis Nelson, wearing an NDX-1 spacesuit, practices scooping up objects and placing them into containers inside the SwampWorks regolith bin at NASAā€™s Kennedy Space Center in Florida. The university team is analyzing the prototype suitā€™s ability to protect astronauts while allowing them the flexibility to dig samples and perform other tasks in regolith, a fine, powdery soil similar to that found on Mars.
