J.B. Carr Tennis Bubble

Located on the MIT campus along Vassar Street, the J.B. Carr Tennis Bubble serves as the central indoor venue for university athletics and recreational tennis in Cambridge. Housing four regulation hard courts beneath an air-supported membrane, the facility delivers consistent, climate-controlled playing conditions regardless of New England weather. The cushioned acrylic courts offer a reliable medium-pace bounce that suits both collegiate competition and spirited campus recreational matches. Primarily catering to MIT students, varsity athletes, faculty, staff, and DAPER facility members, the bubble buzzes with action from early morning practice to late evening intramural play. Court reservations are managed directly through the MIT Recreation digital portal, allowing registered account holders to secure specific hitting blocks in advance. The space emphasizes athletic focus and clean court performance, providing an essential covered training base that keeps the local tennis community active throughout the coldest months of the academic year.
