Abstract :
ALEXIS, one of the most sophisticated miniature satellites developed to date and the first satellite project led by Los Alamos National Laboratory, carries both soft X-ray astrophysics and ionospheric physics experiments. It is an example for experimenters who desire better, faster, and cheaper access to space. The satellite was launch-ready 3 1/2 years after concept. The soft X-ray experiment, ALEXIS, is a novel set of wide-angle, normal incidence telescopes which scan half the sky every satellite rotation. BLACKBEARD is a broadband receiver and digitizer designed to study ionospheric propagation in the 25-175 MHz band. The spin-stabilized spacecraft is compact and efficient; for example, it provides 50 W to the payload while consuming 10 W itself. ALEXIS will fly on a Pegasus air-launched booster
