Scientific Goals (in plainer English)
Can we understand our Sun in the context of other stars? By putting a birth date on the oldest stars in the solar neighbourhood, can we set a limit on the age of the Universe? How do strong magnetic fields affect the physics of other stars and our own Sun? What are mysterious planets around other stars really like? How did the atoms which make up our planet and our very bodies escape from stars in the first place?
What MOST does?
It performs ultra-
An optical telescope with a collecting mirror only 15 cm across, feeding a CCD camera
with a Marconi 47-
The camera is equipped with an array of Fabry microlenses which project a large stable image of the telescope pupil illuminated by target starlight, which is key to the highest photometric precision of MOST. For low cost and high reliability, the instrument has no moving parts. The structure automatically maintains the same focus across a wide range of temperatures, and exposure times are controlled by rapid frame transfer of the CCDs. The CCDs are cooled by a passive radiator system.
The Instrument is housed in a suitcase-
