Scientific paper
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. This paper describes 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 (RHU) 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.
