ESA's Mars Express Sends Back First Mega Strip

very small extract of the first super strip from ESA's Mars Express orbiter. Full size image here
Paris - Mar 30, 2004
The biggest postcard in the world does not fit into any known terrestrial letterbox. It measures 24 metres by 1.35 metres and shows a 3700-kilometre long, 166-kilometre wide strip of Martian landscape in south-north direction.

This postcard of Mars shows a section of surface covering 380 000 square kilometres, an area bigger than Germany. It contains 2.5 gigabytes of uncompressed data. The picture was taken from an altitude of between 275 and 830 kilometres by the HRSC on board ESA's Mars Express orbiter.

Because of the varying height from which the photograph was, the section of Mars shown has also different dimensions: at the start, the width is 166 kilometres, at the orbiter's closest point to Mars the width is 62 kilometres, and at the end it is 78 kilometres.

The picture starts at 52 degrees South and ends at 12 degrees North, the Gusev crater and the NASA Spirit rover landing site lies at about 14.5 degrees South. The European Mars Express spacecraft flies at a speed of one to four kilometres per second over the surface of Mars, depending on its altitude.

Martian South Pole Not Just Dry Ice
Moffett Field - Mar 22, 2004
Astronomers have known for years that Mars possessed polar ice caps, but early attempts at chemical analysis suggested only that the northern cap could be composed of water ice, and the southern cap was thought to be carbon dioxide ice.
