EQUULEUS

EQUULEUS [JAXA]

EQUULEUS (Equilibrium Lunar-Earth point 6U Spacecraft) is a small lunar mission designed jointly by the Japan Aerospace Exploration Agency (JAXA) and the University of Tokyo.

It will measure the distribution of plasma that surrounds the Earth to help scientists understand the radiation environment in the region of space around Earth. It will also demonstrate low-energy trajectory control techniques, such as multiple lunar flybys, within the Earth-Moon region.

EQUULEUS is one of 13 cubesats planned to be carried with the Orion EM1 mission into a heliocentric orbit in cis-lunar space on the maiden flight of the SLS (Block 1) iCPS launch vehicle in 2019.
