摘要

The development team for NASA's ambitious 2009 next Mars rover is beginning to assess tradeoffs to the vehicle's weight, electrical power and "Skycrane" landing mode to reduce risk and hold costs. The mission objectives will propel new U.S. technology development in robotics, sensors, nuclear power and artificial intelligence. In Earth terms, the Skycrane concept envisions the large Mars Science Laboratory (MSL) rover being lowered like a Jeep might be lowered from a helicopter, though of course it would be 100 million mi. from Earth (see diagram). The rover would be reeled down on a lanyard from a rocket-borne platform that has plummeted by aeroshell into the Martian atmosphere at 12,000 mph. and then slowed to a hover just 15 ft. above the surface.
