For many years, cardiologist Mario Motta has made outstanding contributions to public education, in schools and other venues. Since his presidency of the Amateur Telescope Makers of Boston in 1994, Motta has guided that organization in producing widespread public-school star parties. As a participant in the ASP's Project ASTRO, Motta gives bimonthly talks to 5th- and 6th-graders, particularly in his hometown of Lynnfield. His efforts led the Lynnfield Parent-Teacher Association to raise funds for the purchase of an inflatable planetarium, and Motta continues to train teachers to take full advantage of its capability.
