NASA has selected ten studies under the Planetary Science Deep Space SmallSat Studies (PSDS3) program, to develop mission concepts using small satellites to investigate Venus, Earth's moon, asteroids, Mars and the outer planets.
For these studies, small satellites are defined as less than 180 kilograms in mass (about 400 pounds). CubeSats are built to standard specifications of 1 unit (U), which is equal to 10x10x10 centimeters (about 4x4x4 inches). They often are launched into orbit as auxiliary payloads, significantly reducing costs.
"These small but mighty satellites have the potential to enable transformational science," said Dr. Jim Green, director of the Planetary Science Division at NASA Headquarters in Washington. "They will provide valuable information to assist in planning future Announcements of Opportunity, and to guide NASA's development of small spacecraft technologies for deep space science investigation."
NASA's Science Mission Directorate is developing a small satellite strategy, with the goal of identifying high-priority science objectives in each discipline that can be addressed with CubeSats and SmallSats, managed for appropriate cost and risk. This multi-disciplinary approach will leverage and partner with the growing commercial sector to collaboratively drive instrument and sensor innovation.
The PSDS3 awardees were recognized Monday at the 48th Lunar and Planetary Society Conference in The Woodlands, Texas. The total value of the awards is $3.6 million.
The recipients are:
Valeria Cottini, University of Maryland, College Park: CubeSat UV Experiment (CUVE), a 12-unit CubeSat orbiter to measure ultraviolet absorption and nightglow emissions to understand Venus' atmospheric dynamics.
Timothy Stubbs, NASA Goddard Space Flight Center, Greenbelt, Maryland: Bi-sat Observations of the Lunar Atmosphere above Swirls (BOLAS), tethered 12-unit CubeSats to investigate the lunar hydrogen cycle by simultaneously measuring electromagnetic fields near the surface of the moon, and incoming solar winds high above.
Benton Clark, Lockheed Martin Space Systems Company, Littleton, Colorado: CubeSat Asteroid Encounters for Science and Reconnaissance (CAESAR), a constellation of 6-unit CubeSats to evaluate the bulk properties of asteroids to assess their physical structure, and to provide constraints on their formation and evolution.
Anthony Colaprete, NASA Ames Research Center, Moffett Field, California: Aeolus, a 24-unit CubeSat to directly measure vertically-resolved global winds to help determine the global energy balance at Mars and understand daily climate variability.
Icy Bodies and Outer Planets
Robert Ebert, Southwest Research Institute, San Antonio, Texas: JUpiter MagnetosPheric boundary ExploreR (JUMPER), a SmallSat to explore Jupiter's magnetosphere, including characterizing the solar wind upstream of the magnetosphere to provide science context for future missions such as the Europa Clipper.

After a two-month stay aboard the International Space Station, NASA's Technology Educational Satellite (TechEdSat-5) that launched Dec. 9, 2016, was deployed on March 6, 2017 from the NanoRacks platform and into low-Earth orbit to demonstrate a critical technology that may allow safe return of science payloads to Earth from space. Orbiting about 250 miles above Earth, the Exo-Brake, a tens ... read more
