For many years I have been wondering if Aliens existed. I am about to tell you what they have recently discovered on Mars.
On August 5th 2012, NASA sent a Rover to Mars to discover if there is life, take photos and collect samples from the ground to see what it is made of. The shuttle that took the Rover there travelled at 13,200 miles per hour and it took over 8 months to get there.
The Rover was powered by nuclear power and it landed safely inside a crater on mars called the Gale crater. The Odyssey satellite was there also and sent pictures back to earth to show its safe arrival.
It was a great mission but I am still wondering whether they will ever find life on Mars.
