NASA picks small spacecraft propulsion systems for development

NASA has selected three proposals for the development of lightweight micro-thruster propulsion technologies that are small in size but have big potential.

NASA’s Space Technology Mission Directorate selected the miniaturized electrospray propulsion technologies to perform stabilization, station keeping and pointing for small spacecraft. NASA hopes these technology demonstrations may lead to similar position control systems for larger spacecraft and satellites as well.

NASA’s Game Changing Development Program, managed by the agency’s Langley Research Center in Hampton, Va., sponsored this solicitation and will oversee the first phase of this technology development.

The three awards selected for contract negotiations are:

  • “Microfluidic Electrospray Propulsion (MEP),” by NASA’s Jet Propulsion Laboratory, Pasadena, Calif.
  • “Miniature ElectroSpray Thrusters Based on Porous Surface Emission,” by Busek Company, Inc., Natick, Mass.
  • “Scalable ion Electrospray Propulsion System (S-iEPS),” by the Massachusetts Institute of Technology (MIT), Cambridge

Proposals for this solicitation were received from NASA centers, federally funded research and development centers, universities and industry. At least one electrospray technology will be selected for further development as an in-space flight demonstration through NASA’s Small Spacecraft Technology Program during Phase II, which will be made through a separate solicitation.

One of NASA’s priorities is to seek and develop new technologies that will radically change the capabilities for small satellites. There currently is a lack of efficient propulsion for a class of low cost, nanosatellite research spacecraft called “Cubesats,” which measure about 4 inches on each side and weigh less than 3 pounds. The successful development and demonstration of these miniaturized systems will offer low mass, low-power propulsion for these small spacecraft and potentially revolutionize the future of Cubesats.

Miniaturized electrospray propulsion technologies also signal a revolutionary alternative for position control systems for larger satellites. Several studies have shown that micro-thrusters could replace currently accepted systems on large spacecraft, saving weight and space while significantly increasing mission reliability and lifetimes. This technology also could enable other game changing propulsion capabilities from micro-scale to large, deployable spacecraft structures.
