DESCRIPTION:BRITE-Constellation: Nano-Satellites for Stellar Astrophysics R
 esearch: Why Centimeter-Class Telescopes in Space need Meter-Class Telesco
 pes on Ground?\nDr. Rainer Kuschnig\n\nBRITE-Constellation (BRight Target 
 Explorer) consists of six nano-satellites aiming to study of variability o
 f the brightest stars in the sky. Austria, Poland, and Canada contribute t
 wo spacecraft each all launched into low earth orbits. The satellites have
  the same structure: they are 20 cm cubes, 7kg mass, with a CCD photometer
  fed by 3 cm aperture telescopes. The main difference between pairs of sat
 ellites is the instrument passband which set to blue (400-450nm) or red (5
 50-700nm). The core scientific objective is to obtain high precision two c
 olor photometry, with a time base of up to 180 days, of stars brighter tha
 n 4.5 mag in order to study stellar pulsations, spots, and granulation, ec
 lipsing binaries, search for planets and more.Since the launch of the firs
 t two BRITE satellites in February 2013 more than 5 and a half years of ex
 periences in space have been gathered to run the mission and a summary of 
 lessons learned will be presented.  By now more than 20 peer-reviewed
  scientific articles have been published based on data collected by BRITE-
 Constellation satellites in space and most results presented therein benef
 itted greatly from supplementary spectroscopy by meter size telescopes obt
 ained on ground.
