It’s an age-old question that has inspired countless cheesy alien movies: is there life on other planets? This is where Curiosity comes into play—the rover that recently landed successfully on Mars in the Gale crater, an ancient, gaping hole created by a meteor millions of years ago. At the size of a small car, the rover is larger than any other similar device and traveled 154 million miles from Earth to Mars. A variety of photos and evidence will be collected to see if Mars does contain life, or had a past terrain that could have supported life. NASA and the Jet Propulsion Laboratory, which are responsible for the successful landing of Curiosity, are hoping the rover can yield results worth the $2.5 billion cost of the mission. At that price tag, let’s hope if anyone is out there, Curiosity will find them.
