The Microsatellite DD SEP Module enables multiple missions for NASA such as asteroid surveying, interplanetary exploration, sample return systems and technology demonstrations. NASA has identified over a dozen potential asteroids for human exploration. Using low cost microsatellites to fly past these objects and determine their composition ahead of a manned mission provides a means for mission planners to select a destination with the highest chance of mission success. Additionally, the low cost of the satellites enables small, low cost missions to be flown to the Moon, Mars or Venus. While the payload capability of each mission is reduced, a series of missions can be performed at fraction of the cost of a single large mission. Similarly, the high delta V system can be used to return small samples from distant bodies such as the Moon, Mars, Mars' moons or asteroids. These missions typically require large delta-Vs and small packaging to be financialy viable. Lastly, the system enables technology demonstrations identified by NASA such as SEP spiral-out from LEO, DD plasma/array interaction, and radiation belt measurement to be performed at low cost. In addition to NASA, the technology provides capabilities to many other users. In particular, there is a growing number of small/micro launch vehicles such as ALASA being developed. The DD SEP module provides a means to boost these payloads from LEO to as far as GEO, enabling longer orbit lifetimes and mission possibilities for commercial and government operators.
