Tampa Astronomy Club

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. We are also members of both the Astronomical League and Night Sky Network. 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 with. We invite you to attend one of our monthly meetings as our honored guest.

Monthly meetings are normally held on the 3rd floor of MOSI in the Science Works 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.


If you are interested in joining MARS, you will need to complete and return this Membership Application to the Membership Chairman. The current cost to join is $27.50 for an individual membership, and $37.50 dollars for family membership. Click here to find out the benefits of membership

Plate Tectonics & Planetary Evolution

Our very own member, HCC Astronomy Instructor and fellow stargazer Dave Feller presents the exciting and unique topic of Plate Tectonics & Planetary Evolution. Surface features on terrestrial planets evolve over time. Some of these processes are catastrophic and act very quickly, while others are evolutionary and develop much more slowly. Plate tectonics theory explains how heat generated inside a planet causes (usually) slow, evolutionary changes on a planetary surface. Join us and learn how events such as volcanic eruptions, earthquakes, and the formation of new ocean basins are driven by plate tectonics here on Earth, and how these concepts apply to other terrestrial planets.
