The value of EOT in degrees is usually converted to solar-minutes to give the correction to mean solar time to obtain true solar time. The value of EOT for Mars over the Mars Observer mapping phase is plotted.
The Mars Global Surveyor spacecraft was launched on November 6, 1996 and was captured into a highly elliptical, 45 hour orbit around Mars with a 973 m/s propulsive maneuver on September 12, 1997.
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.
