Summary
MOST (Microvariability and Oscillations of Stars) is a Canadian astronomy satellite with NORAD catalog ID 27843, launched on June 30, 2003, from Plesetsk Cosmodrome LC133/3 using the Rokot launch vehicle. With dimensions of 0.3 meters in length and 0.7 meters in diameter and span, it has a dry mass of 60 kilograms, identical to its launch mass. Equipped with a 15 cm telescope and photometer, MOST was designed for a one-year mission but achieved an operational lifetime of fifteen years. The satellite is powered by solar cells and batteries and has a box shape with a reflective surface area (RCS) of 0.2867 square meters. Owned by the Canadian Space Agency (CSA), MOST was manufactured by Dynacon Enterprises Ltd., aimed at astronomical observations to study microvariability and oscillations in stars.
