The Mars rover Curiosity is a huge leap forward from previous rover technology; this sophisticated device was created by NASA and was launched on the 26th November 2011. After its 560-million-kilometer (350-million-mile) journey from Earth, the rover managed to perform some extremely complicated preprogrammed maneuvers in order to successfully land on Mars. This rover is an extremely expensive piece of technology, costing NASA some 2.5 billion dollars. This is the highest amount of money NASA has ever spent on a rover.
Curiosity’s landing in Gale Crater was called the 7 minutes of terror, because NASA would not know for 7 minutes if the landing was successful. (The signal takes 7 to 14 minutes to travel from Mars back to NASA.) NASA chose Gale Crater for a number of reasons, one of them being that it was a big and safe crater for landing.
The rover has a weight of approximately 900 kilograms (1,900 pounds).
The process of landing was as follows:
Overall, this rover is the most sophisticated piece of technology NASA has ever sent to Mars.
