|Lunar IceCube, a 6U CubeSat designed to prospect for water in solid, liquid and vapor forms and other volatiles from a low-perigee, highly inclined lunar orbit, has been selected by NASA to fly on Exploration Mission-1 (EM-1). The mission is a partnership between Morehead State University, NASA Goddard Spaceflight Center, JPL, the Busek Company, and Vermont Tech. Lunar IceCube will be deployed during lunar trajectory by the Space Launch System (SLS) and use an innovative RF ion engine to achieve lunar capture and the science orbit (inertially locked, highly elliptical, 100 km periapsis) to investigate the distribution of water as a function of time of day, latitude and regolith composition in the context of lunar mineralogy. IceCube will include the Broadband InfraRed Compact High Resolution Exploration Spectrometer (BIRCHES), developed by GSFC- a compact version of the successful New Horizons instrument designed with the high spectral resolution (5 nm) and wavelength range (1 to 4 μm) needed to distinguish forms of water, including ice. The mission will complement the scientific work of other missions by focusing on the abundance, location and transportation physics of water ice on the lunar surface at a variety of latitudes. Lunar IceCube, while primarily a science mission, will demonstrate technologies that will enable future interplanetary exploration with small satellite platforms including radiationhardened subsystems, a precise ranging transponder/transceiver, a capable attitude determination and control system, a high power solar array and an innovative electric propulsion system (EP). The EP (Busek BIT-3 Iodine engine) generates 1.2 km-1 of delta-v and, combined with an innovative low energy manifold trajectory, allows the spacecraft to reach lunar orbit from Earth escape with minimal energy. The 13 secondary payloads to be deployed on EM-1, including Lunar IceCube, will usher in a new era of solar system exploration with small satellite platforms.

Morehead State University is leading the mission in partnership with NASA Goddard Spaceflight Center, JPL, Busek and Vermont Tech. It was selected under NASA’s Next STEP program and will fly on Exploration Mission-1 in 2018.|
Benjamin K Malphrus is a Professor of Space Science at Morehead State University. He has served as Scientific Staff of the National Radio Astronomy Observatory, NASA’s Wallops Flight Facility, the University of South Carolina and West Virginia University. He served as Principle Investigator (PI) on nanosatellite missions including KySat-2, the Cosmic X-ray Background Nanosatellite (CXBN), and CXBN-2, and had various roles on other small satellite missions. He is currently PI of the Lunar IceCube Mission- a $15 M NASA project designed to investigate the transport physics of water ice on the Moon. He has published papers on topics ranging from “Extragalactic astrophysics to instrumentation in radio astronomy, to nanosatellite systems development” and was awarded over $18 million R&D grants funding. In the late 1990s, he developed a theory of galaxy formation that has gained wide acceptance among the astronomical community.
