NASA Selects CubeSat, SmallSat Mission Concept Studies
Jet Propulsion Laboratory
March 23, 2017

NASA has selected 10 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 about 4x4x4 inches (10x10x10 centimeters). 
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 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 this week 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:

Venus

Christophe Sotin, NASA's Jet Propulsion Laboratory, Pasadena, California: 
Cupid's Arrow, a 66-pound (30-kilogram) probe to measure noble gases and 
their isotopes to investigate the geological evolution of Venus and why 
Venus and Earth have evolved so differently.

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.

Moon

Suzanne Romaine, Smithsonian Astrophysical Observatory, Cambridge, Massachusetts: 
CubeSat X-ray Telescope (CubeX), a 12-unit CubeSat to map the elemental 
composition mapping of airless bodies such as the moon, to understand 
their formation and evolutionary history using X-ray pulsar timing for 
deep space navigation.

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.

Asteroids

Jeffrey Plescia, Johns Hopkins University Applied Physics Laboratory, 
Laurel, Maryland: Asteroid Probe Experiment (APEX), a SmallSat with a 
deployable seismometer to rendezvous with the asteroid Apophis and directly 
explore its interior structure, surface properties, and rotational state.

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.

Mars

David Minton, Purdue University, West Lafayette, Indiana: Chariot to the 
Moons of Mars, a 12-unit CubeSat with a deployable drag skirt to produce 
high-resolution imagery and surface material composition of Phobos and 
Deimos, to help understand how they were formed.

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

Kunio Sayanagi, Hampton University, Virginia: Small Next-generation Atmospheric 
Probe (SNAP), an atmospheric entry probe to measure vertical cloud structure, 
stratification, and winds to help understand the chemical and physical 
processes that shape the atmosphere of Uranus.

Robert Ebert, Southwest Research Institute, San Antonio: 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.
