How Did The Massive Curiosity Rover Safely Land On Mars?
The Curiosity Rover is about the size of a car, weighing in at nearly a ton. It measures almost 3m (10ft) long and 2.1m (7ft) tall. To safely land on the Martian surface, Curiosity required a new approach. The rover was lowered by tethers that extended from a sky crane. The other rovers that landed on Mars were small enough to just bounce down on the surface wrapped in airbags.
