As NASA's planetary exploration budget is squeezed, NASA scientists are finding new ways to lower the costs of future Mars rover missions.
With a large NASA rover only weeks away from arriving at the Red Planet, NASA's Doug McCuistion outlined ideas for another, far less expensive Martian mission in 2018 or 2020.
The inflatable decelerators, also known as ballutes, and big parachutes would help the spacecraft reduce its speed through the Martian atmosphere, while the atomic clocks would improve its landing accuracy, McCuistion announced Tuesday (July 10) at the Farnborough International Airshow here.
NASA expects to have up to $800 million to spend on the mission. That's a far cry from the $2.5 billion the agency is spending on its 1-ton Curiosity rover, which is due to land on the Red Planet Aug. 5.
