On August 5, 2012, at 10:17 p.m. PDT, NASA's giant rover Curiosity landed on Mars, the fourth planet in our solar system from the Sun. Curiosity rover is 3 meters long, 2.8 meters wide, and 2.1 meters tall weighing 900 kilograms (around 2,000 lbs). Slowing the giant laboratory down from entry-level hypersonic speeds to near zero and safely landing it on Martian surface was immensely complicated. It required a rocket-powered crane to land the rover on the surface. Curiosity's primary goal was to determine if Martian soil and climate offered favorable conditions for life in past. The rover contains several instruments on board to understand the planet conditions better. These instruments include spectrometers for material characterization, radiation detectors, cameras for taking pictures (and selfies), and weather sensors.
