Abstrakt

BRITE-Constellation currently consists of two satellites, UniBRITE and BRITE-AUSTRIA (TUG-SAT1). Each will fly a CCD camera to perform high-precision two-color photometry continuously for two years or more, primarily of stars brighter than 4th magnitude (V), and with reduced accuracy also of stars down to 7th magnitude. The primary science goals are studies of massive stars in our Galactic neighbourhood, representing objects which dominate the ecology of our Universe, and also evolved stars (giants) to probe the future development of our Sun. BRITE-Constellation is made possible by innovative technology currently developed in collaboration between Canada and Austria. A launch of UniBRITE and BRITE-AUSTRIA in late 2009 is envisioned. An expansion of BRITE-Constellation may be funded by the Canadian Space Agency (CSA). The operation policy will be to observe a few fields over a long time span and possibly some short runs in between, which will assure optimum use of near polar low-earth orbits.
