Advanced Photovoltaic and Electronic Experiments
APEX was a U.S. Space Test Program satellite built around the PegaStar platform to study photovoltaic and electronic hardware in the space environment. Its principal PASP Plus payload exposed diverse solar-cell technologies to plasma and radiation while diagnostic instruments measured arcing, leakage current, radiation, spectral irradiance, and array performance across an elliptical orbit.

- Description
- APEX was a U.S. Space Test Program satellite built around the PegaStar platform to study photovoltaic and electronic hardware in the space environment. Its principal PASP Plus payload exposed diverse solar-cell technologies to plasma and radiation while diagnostic instruments measured arcing, leakage current, radiation, spectral irradiance, and array performance across an elliptical orbit.
- Launch Site
- Outcome
- APEX reached its planned elliptical orbit and completed a 69-month flight. PASP Plus gathered data from August 1994 through August 1995, returning an unusually broad record of solar-array behavior in plasma and radiation environments, while the mission's calibration and electronics experiments supported improved spacecraft power-system design and test standards.
