ALEXIS is one of the most sophisticated miniature satellites developed to date, and the first satellite project led by Los Alamos National Laboratory. It carries both soft X-ray astrophysics and ionospheric physics experiments. As such, 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 broad-band 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 Watts to the payload while consuming 10 Watts itself. ALEXIS will fly on a Pegasus air-launched booster. The authors discuss the ALEXIS integration history and lessons learned therein.
