Surveyor Returning New Images


JPL - May 10, 1999 -
Mars Global Surveyor is healthy and all of its science instruments are turned on. A gimbal, or hinge, on the spacecraft's dish-shaped high-gain antenna still has a restriction that limits its range of motion, but this will have no effect on the mission until next February when the Mars-to-Earth geometry will again prevent the antenna from pointing continuously at Earth.

Engineers are looking at options for conducting the mission after February so that there will be a minimal impact on how much science data the mission can collect and send to Earth.

At 7:45 a.m. Pacific time today, Global Surveyor fired its small thrusters for about two minutes in order to fine-tune its orbit around Mars. The mapping orbit was designed so that the spacecraft does not fly over precisely the same swath of Martian landscape, or "ground track," from one week to the next.

The spacecraft must fire its thrusters every few months to keep the necessary ground-track separation. This is especially important now since the science team is in the process of an intensive four-week campaign to acquire stereo images of the planet.

    Satellite Launch To Boost DTH In India
     Calcutta, India (SPX) Dec 28, 2005
     The successful launch Thursday of India's heaviest satellite from spaceport of Kourou in French Guyana may have boosted the country's space research efforts to yet another level, but it has also lifted the spirits of at least three Direct-To-Home televisions broadcasters, one of which has been waiting for years to launch its services in India.
