A multiplicity of missions,ere to be released several hours before the main spacecraft entered orbit, there was no way to revise either the time of landing or the target site. By sheer bad luck, one of the most extensive dust storms ever observed was raging when they attempted to land on 27 November and 2 December. After entr

To a first approximation, there are two morphologically distinctive hemispheres. The transitional ‘line of dichotomy’ has its most northerly point at about 330 degr

Infrared data from Mars Global Surveyor indicated that this dust had warmed the upper atmosphere on a . basis, and it was calculated that the diminished air density would reduce the efficacy of the first phase of the braking process.

As well as casting fascinating new insights into Mars’ past, this discovery is also forcing a complete rethink about the mechanisms of global planetary change and the
