Engineers commanded Curiosity to drill its third drill hole on Tuesday on what looks like an outcrop of sandstone in Gale Crater.

This hole is shallow and is merely a test to see if a deeper full bore would be worthwhile geological.

That Curiosity has only drilled three holes, and is now only doing a test bore first is partly because engineers fear that using the drill too much will cause a short circuit that will disable the rover entirely. This fear is because of a design flaw in the construction of the rover and the drill.

    Sounds like not enough destructive testing done while it was still here, where something could be done about it. I forgot, not done with real money, done with government cash, two different things!
