The Curiosity Rover is a huge project of NASA. They have organised, developed and built an exploration vehicle to land on Mars and explore the South Pole area of the planet. This is to determine if there was once life on the Red Planet. It will take a great deal of time, but much has been put into this project.
A multitude of Scientists are working from Earth and feeding programmes into the Curiosity Rover so that it can conduct all manner of experiments. This is one of the most exciting leaps forward since the first Apollo Moon landing.
Other probes and land vehicles have landed upon the Martian surface before, but these have met with very limited success and none where the search for alien life is concerned. Now this new robotic laboratory can roam the Martian surface controlled by NASA personnel on Earth after a most successful landing on the Red Planet's surface.
