6U Cubesat to Mars
« on: 08/22/2015 02:04 AM »
What sort of configuration is required for a 6U cubesat to propel itself to Mars from GTO and propulsion tech? How much payload will be left to operate at Mars in kg? This will have solar arrays also. What would be the cheapest way to launch?

Micro landers, not cubesat but the lander equivalent. At 3.5kg they could in theory be delivered to Mars by a 12U cubesat and maybe use the cubesat as a comms relay.

From canyons to glaciers, from geology to astrobiology, the amount of exciting surface science awaiting us at Mars greatly outstrips available mission opportunities. Based on the thrice-flown Aerospace Corporation Earth Reentry Breakup Recorder (REBR), we present a method for accurate landing of small instrument payloads on Mars, utilizing excess cruise-stage mass on larger missions. One to a few such microlanders might add 1-5% to the cost of a primary mission with inconsequential risk. Using the REBR and JPL Deep Space 2 starting points for a passively stable entry vehicle provides a low mass and low ballistic coefficient, enabling subsonic deployment of a steerable parawing glider, capable of 10+ km of guided flight at a 3:1 glide ratio. Originally developed for the Gemini human space program, the parawing is attractive for a volume-limited microprobe, minimizing descent velocity, and providing sufficient remaining volume for a useful scientific payload. The ability to steer the parawing during descent offers unique opportunities, including terrain-relative navigation for landing within tens of meters of one of several specified targets within a given uncertainty ellipse. In addition to scientific value, some Mars human exploration Strategic Knowledge Gaps could be addressed with deployment of focused instruments at multiple locations.
