MOST

NSSDCA/COSPAR ID: 2003-031D

Description

MOST is a Canadian (CSA) astronomy satellite that was launched by a Rokot rocket from Plesetsk at 14:15 UT on 30 June 2003. The 65 x 65 x 30 cm, 51 kg satellite carries a 15 cm aperture reflecting telescope to monitor the brightness variations in a star caused by soundwaves on its surface, or from reflections from an orbiting planet. Because of its light weight and low cost, it has been dubbed as Humble Telescope.

The science goals of MOST are to: (1) study the astroseismology of acoustic and gravity-mode oscillations in a variety of stars and to probe their internal structures and evolutionary states; (2) analyze the transits and eclipses of exoplanets around Sun-like stars and red dwarf stars; (3) measure the turbulent variations in massive evolved (Wolf-Rayet) stars; and, (4) measure the structure and variability of gas and dust disks around pre-main-sequence stars.

Data generated by MOST is available from the MOST Public Data Archive at: http://most.astro.ubc.ca/data/data.html
