Welcome to the Mount Diablo Astronomical Society
M.D.A.S. was formed in 1957 as part of the National "Moonwatch" program established to time the first man-made satellites so accurate orbits could be calculated.
Within months of the club's formation, astronomy and space science made a giant leap into the households and classrooms of Americans with the launching of Sputnik, and soon afterwards Explorer I. The space race was on, kindling a desire in many to understand more about space and astronomy, and what the newly formed NASA was planning. We hold monthly meetings in Concord, CA, as well as Public and Society Astronomy Programs on Mt. Diablo.
