Then it was shipped to Kennedy Space Center in Florida where it was launched. It took 7 months to get to Mars. Parts of the spacecraft include Cruise Stage, Backshell, Descent Stage, Perseverance, and the Heat Shield.
Getting to the Surface of Mars is called EDL – Entry, Descent, and Landing. This must happen autonomously. The main purpose of the rover is to search for signs of life.
Scientific instruments include SuperCam, MastCam-Z, MEDA, SHERLOC, WATSON, PIXL, MOXIE, and RIMFAX. The rover also brought along a helicopter called Ingenuity. This is the first helicopter to fly on another planet!/Jared Owen
