Mars survey

In 1997, the Mars Global Surveyor, launched in Nov 1996, went into an elliptical orbit around Mars. To drop into a lower orbit the original mission plan was to use a braking effect by dipping into the upper Martian atmosphere. The lower orbit was a better position for mapping purposes. However, the aerobraking method originally planned was suspended for several weeks to give engineers time to develop more gentle manoeuvers to protect the craft when a solar array failed to deploy correctly, and was flexing excessively. It was to spend two years mapping the surface of Mars.
