BRITE

BRITE-Constellation is an ongoing space mission carrying out two-band photometry in wide fields with a constellation of six (five operational) BRIght Target Explorer (BRITE) nanosatellites. The mission was build by a consortium of three countries, Canada, Austria, and Poland, each operating two BRITE satellites. The six satellites were launched into orbit between February 2013 and August 2014. Each satellite is a cube-shaped spacecraft with sides of 20 centimetres (7.9 in) hosting an optical telescope of 3 centimetres (1.2 in) aperture feeding an uncooled CCD with a field of view of approximately 20° × 24°.

The BRITE satellites were designed by the Institute for Aerospace Studies at the University of Toronto under the Canadian Advanced Nanospace eXperiment Program. The satellites is built around the Generic Nanosatellite Bus, a cube-shaped spacecraft with sides of 20 centimetres (7.9 in) which was first used in current BRITE version for the satellite CanX-3.[1] One satellite is called BRITE-Toronto while the other is called BRITE-Montreal.[2]

BRITE Constellation was included in the #7 entry in the Top Ten Science Stories of 2013, as chosen by Bob McDonald, host of the Canadian Broadcasting Corporation (CBC) radio show Quirks & Quarks, and the main science journalist for CBC radio and television.[3]

Mission

The satellite is intended for astro-photometry of the brightest stars in single wavelength band. UniBRITE-1, BRITE-Toronto and Heweliusz BRITE-PL photometers are sensitive to the red light, while BRITE-Montreal, Lem BRITE-PL and BRITE-AUSTRIA are sensitive to the blue light.[2]
