Usually landers and rovers, takes seven minutes to descend through Mars atmosphere and land on the surface of Mars. This seven minutes of time is the most scary period and is known as "seven minutes of terror," many missions on Mars have failed due to the difficulty in landing on the Red Planet, but the scientists were confident that this rover will safely land there.
Curiosity is the largest rover ever made and this rover will be searching for organic compounds like carbon on Mars, which are the building blocks of life on earth. The rover landed on Gale Crater, which is thought to have been a lake earlier. The reason behind choosing this place is because it is an ideal place for search of organic materials.
Unlike the old rovers, Curiosity is nuclear-powered and does not need solar panels for its energy supply. It has advanced cameras and has a most advanced laboratory for chemical analysis of soil and rock samples.
Obama's science adviser John Holdren described the landing as "an enormous step forward in planetary exploration. Nobody has ever done anything like this. We are actually the only country that has landed surface landers on any other planet," he told NASA television. He also said that the rover was vastly bigger, more capable and more complicated one. Let's hope for the success of this mission.
