The Telecommunications and Mission Operations Directorate (TMOD) of the Jet Propulsion Laboratory is responsible for development, maintenance and operation of flight operations systems for several classes of science missions planned for the next several years.
The Mars Global Surveyor (MGS) mission, scheduled for launch in November 1996, will employ aerobraking as a means of reaching a low altitude, sun-synchronous mapping orbit. This technique is necessary to minimize the cost of the mission. The dry mass of the spacecraft and the launch vehicle capability do not permit an all-propulsive transfer to the desired orbit. Aerobraking concepts are discussed.
Hydrogen evolved by coliform bacteria transferred to separate measurement cell. Electroanalytic cell mounted in insulated temperature-control bath cycled between culturing temperature and sterilizing temperature. Flow of materials into and out of cell controlled by electrically operated valves.
