12 Highlights of NASA calibration activities of interest to the EP CubeSats in NASA s In-Space Validation of Earth Science Technologies (InVEST) program -InVEST provides opportunities to test, demonstrate, and validate new technologies in space prior to use in a science mission (i.e. technical risk reduction) -Program sponsored by NASA s Earth Science Technology Office (ESTO) -In 2015, an InVEST call for proposals targeting small instruments and subsystems to advance technology for Earth science was issued. This call resulted in the selection of 4 proposals using CubeSats as standardized platforms CubeSat: secondary payload instrument using one or several 10 cm cube platforms -Advantages: inexpensive (i.e. reduced size and cost) and capable of being built and launched quickly (i.e. validate against and provide overlap between flights of state of the art instruments) -Government and commercial flight opportunities for secondary payload technology demonstrations are on the increase (e.g. NASA s CubeSat Launch Initiative (CSLI)) Proposals selected: -J.
