Summary
The ALEXIS satellite, also known as 1993-026A, was an experimental spacecraft operated by STP/LANL and manufactured by AEROA. Launched on April 25, 1993, from the AFWTR launch site using a Pegasus launch vehicle, it had a design lifetime of one year but operated for twelve years. The satellite featured spin stabilization with four solar panels and weighed 113 kg both at launch and dry mass. Equipped with an ultrasoft X-ray monitor consisting of six compact normal-incidence telescopes and the Blackbeard equipment, ALEXIS was primarily used for experimental purposes. Its power system included four deployable fixed solar arrays and batteries, supporting its operational requirements throughout its extended mission duration.
