Deep Space Station M-33 was a Starfleet space station located in the Veletus system. It was established in part to study the Ifukube Veil, a phenomenon in orbit of gas giant Veletus V.
Construction began in 2265, and continued through 2267, even as the facility became partially operational. As of that year, its commanding officer was Commodore Julius Merrill. (TOS short story: "Fracture")
