Abstract:
HaloSat is a small satellite (CubeSat) designed to map soft X-ray
oxygen line emission across the sky in order to constrain the mass and
spatial distribution of hot gas in the Milky Way. The goal of HaloSat
is to help determine if hot gas gravitationally bound to individual
galaxies makes a significant contribution to the cosmological baryon
budget. HaloSat was deployed from the International Space Station in
2018 July and began routine science operations in 2018 October. We
describe the goals and design of the mission, the on-orbit performance
of the science instrument, and initial observations.
