NASA announces new CubeSat space mission candidates

CubeSats belong to a class of research spacecraft called nanosatellites. The cube-shaped satellites measure about 4 inches (10 centimeters) on each side, have a volume of about 1 quart (1 liter), and weigh less than 3 pounds (1.1 kilograms).

The selections are from the fourth round of the CubeSat Launch Initiative. After launch, the satellites will conduct technology demonstrations, educational research or science missions. The selected CubeSats will be eligible for flight after final negotiations and an opportunity for flight becomes available.

The following organizations submitted winning satellite proposals:

• The Aerospace Corporation, El Segundo, Calif.
• The Discovery Museum and Planetarium, Bridgeport, Conn.
• Embry-Riddle Aeronautical University, Prescott, Ariz.
• Morehead State University, Morehead, Ky., in partnership with the University of California at Berkeley
• Montana State University, Bozeman (two CubeSats) in partnership with The University of New Hampshire, Durham
• Merritt Island High School, Fla., in partnership with California Polytechnic State University, San Luis Obispo
• NASA's Ames Research Center, Moffett Field, Calif.
• NASA's Goddard Space Flight Center, Greenbelt, Md. (three CubeSats)
• NASA's Jet Propulsion Laboratory, Pasadena, Calif. (three CubeSats)
• NASA's Kennedy Space Center, Fla.
• Pennsylvania State University, in partnership with the Naval Research Laboratory, Monterey, Calif.; and The Aerospace Corporation, El Segundo, Calif.
• Saint Louis University, St. Louis, Mo.
• Tyvak Nano-Satellites Systems, Irvine, Calif., in partnership with the California Polytechnic State University, San Luis Obispo
• University at Buffalo, The State University of New York
• University of Colorado, Boulder
• University of Florida, Gainesville, in partnership with Stanford University
• University of Maryland, Baltimore County
• University of Texas, Austin
• Vanderbilt University, Nashville, Tenn., in partnership with the Radio Amateur Satellite Corporation, Silver Spring, Md.

The three CubeSats from JPL, which is managed for NASA by the California Institute of Technology in Pasadena, are:

• The Integrated Solar Array and Reflectarray Antenna (ISARA), a technology demonstration of a practical, low-cost Ka-band high-gain antenna on a 3U CubeSat that will increase downlink data rates from a baseline of 9.6 kilobits per second to more than 100 megabits per second with minimal impact on spacecraft mass, volume, cost and power requirements.
• The CubeSat VHF transmitter to study Ionospheric dispersion of Radio Pulses (CHIRP), a 6U CubeSat designed to provide measurements of very high frequency (VHF) radio pulses propagated through the ionosphere that will be essential to the development of SWORD, a future explorer class charged-particle astronomical observatory.
• The Interplanetary NanoSpacecraft Pathfinder In Relevant Environment (INSPIRE) project, which will open deep-space heliophysics and planetary science to the CubeSat community by demonstrating functionality, communication, navigation and payload-hosting in interplanetary space on dual 3U CubeSats.

In the three previous rounds of the CubeSat initiative, NASA has selected 63 missions for flight. The agency's Launch Services Program Educational Launch of Nanosatellite (ELaNa) Program has launched 12 CubeSat missions. This year, 22 CubeSat missions are scheduled for flight.
