Welcome to the Museum Astronomical Resource Society, also known as the M.A.R.S. astronomy club. M.A.R.S. is sponsored by the Museum of Science and Industry (MOSI), in Tampa, Florida. This site provides club news and astronomical information to our membership and to the public.

There's only one thing the people of M.A.R.S. enjoy more than observing the heavens... that's sharing it with others! Whether you are new to astronomy and curious about how to experience it, or a seasoned veteran looking for an active club to spend observation time. We invite you to attend one of our monthly meetings as our honored guest.

Monthly meetings are currently being held on the 3rd floor of MOSI in the Science Theater, and take place on the 2nd Friday of each month from 7:00PM to 9:00PM. Meetings are free and open to the public.
