STPSat 4 [USAF Academy]

STPSat 4 is an experimental spacecraft for the Department of Defense's Space Test Program (STP).

STPSat-4 will carry three experiment packages into low earth orbit. One of these is the MSA (Modular solar array).

Among the experiments selected is iMESA-R (Integrated Miniaturized Electrostatic Analyzer Reflight), a U.S. Air Force Academy mission designed to measure plasma densities and energies.

STPSat-4 is a free flying spacecraft to be ejected from the international space station (ISS). Launch is scheduled for late 2017.
