Miniature spacecraft offer the potential to greatly reduce mission costs, but today there is no flight qualified power source that could operate a microspacecraft during a journey to the outer planets. The authors describe the Milliwatt Isotope Power Source (MIPS), a concept capable of reliable, long term electrical power generation in the milliwatt range. Utilizing existing radioisotope heater unit heat source technology and proven thermoelectric energy conversion module technology, a MIPS package about the size of a D-cell battery could deliver about 30 milliwatts of electrical power for several decades and weigh 70 grams. Such a power source could be used to power miniature instruments such as seismometers, propel a microrover or provide decentralized power aboard a more conventional spacecraft. Also, reliance on flight-qualified heat source technology and the small radioisotope inventory required are attractive safety considerations. (1 Reference).
