The US space agency is preparing for its newest Mars rover, Curiosity, to touch down on the Red Planet on August 6. The rover’s entry and descent will be nerve-wracking for NASA engineers, compounded by a 14-minute delay as the rover’s signals travel to Earth from Mars. If successful, Curiosity will be the seventh NASA spacecraft to land on the Red Planet.(6)Curiosity will be traveling at about 20,000 kilometers per hour when it hits the Martian atmosphere.(7)It will have only seven minutes to reduce its speed for a soft landing. NASA engineers will not be able to control or even witness the events in real time. They call this period " seven minutes of terror. " Ideally, after a parachute deploys, engines will fire for a powered descent. Curiosity will be lowered to the Martian surface on cables and cut loose. Then the rocket pack will blast off. Curiosity is the size of a small car and has 17 cameras. It’s much larger than previous rovers and can travel as far as 200 meters per day. It’s a nuclear-powered mobile laboratory.
