If you've been following the progress of the Curiosity rover on Mars, there's a bit of new information to add to your trivia knowledge. NASA has officially used the last tool on Curiosity in a test to make sure it is functioning. Curiosity is equipped with a drill capable of drilling into rocks to retrieve samples from inside.
The ability to drill into rocks is an important one as these stones record the history of the planet millions and billions of years at a time. NASA is currently testing the drill to make sure everything is functioning properly. After positive results come back, NASA will order Curiosity to drill further into this rock to obtain samples.
The samples will then be analyzed in Curiosity's on-board chemistry lab to determine their chemical and mineral composition. The hope is that the results will show that life either existed previously or could have existed.
