ESA Shows Off Quadcopter Landing Concept For Mars Rovers 104

coondoggie writes Taking a page from NASA's rocket powered landing craft from its most recent Mars landing mission, the European Space Agency is showing off a quadcopter that the organization says can steer itself to smoothly lower a rover onto a safe patch of the rocky Martian surface. The ESA said its dropship, known as the StarTiger's Dropter is indeed a customized quadcopter drone that uses a GPS, camera and inertial systems to fly into position, where it then switches to vision-based navigation supplemented by a laser range-finder and barometer to lower and land a rover autonomously.

    Mars has an atmosphere. Barely - atmospheric pressure is 0.006 earth-atmospheres. Maybe 0.01 if the weather is right and at a low enough point. You'd get bugger-all lift from a 'copter, quad or otherwise. Even in the nice one-third G, that thing isn't flying. It's hard enough getting something down by parachute - those rovers have to be built to take a nasty impact, because even with a huge parachute and low gravity they still hit the ground hard.

    If you've never watched "Seven Minutes of Terror," which explains the crazy but successful scheme to lower the Curiousity rover onto Mars, do yourself a favor and go here: http://www.youtube.com/watch?v... [youtube.com]

    It's the best video the U.S. Government has ever produced.

    Nor will GPS help much on Mars. It's like this is a thinly veined cover for developing a military drone for dropping materiel into a battle zone. Everything about it seems geared towards terrestrial use.

    a customized quadcopter drone that uses a GPS, camera and inertial systems to fly into position .....

    Yup, hate to break it to you rocket scientists at NASA, but there is a slight flaw in this design for use on Mars.

    I'd suspect those rocket scientists planned to, oh, I dunno, put GPS satellites into orbit around mars prior to landing the rover?

If you can't get your work done in the first 24 hours, work nights.
