Mars Global Surveyor Update
News story originally written on January 25, 1997
According to the most recent flight status report printed on January 24, 1997,
the Mars Global Surveyor is in excellent condition and well on its way to the
dusty red planet. The Mars Global Surveyor (MGS) was launched from Earth on
November 7, 1996 by NASA. Its mission is to continue the exploration of Mars
that began with the Mariner mission in 1971 and the Viking mission in the
mid-1970s. With several remote sensing instruments, MGS will gather information
about the Martian topography, magnetism, mineral composition, and atmosphere.
In addition, the entire planet will be photographed.
MGS is expected to reach Mars on September 12, 1997. It is currently 17.52
million kilometers (10 950 000 miles) from Earth and 125.97 million kilometers
(78 731 000 miles) from Mars. It is moving in an orbit about the Sun with a
velocity of 30.35 kilometers per second.
Once MGS reaches Mars, it will allow itself to be captured by Mars' gravity and
then swing into a highly elliptical orbit with the planet. It will make several
passes around the Martian globe, taking photographs and gathering information.
Eventually MGS will enter into a circular orbit and continue to obtain
The MGS flight team makes continuous checks of all systems.
Overall, the Mars Global Surveyor is well on its way to the Red Planet and is
expected to be provide large amounts of important data to the scientists of
