ESA MARS EXPRESS (2003-2020?)
Nereidum Mons (no elevation data)
MARS (Argyre quadrangle)
The Mountains
The Nereidum Montes is a mountain range on planet Mars. It stretches 3,677 km, northeast of Argyre Planitia. It is in the Argyre quadrangle. The mountains are named after a Classical albedo feature.
There is a crater at 45.1°S, 55.0°W on the Nereidum Montes that is similar to Galle in that it also has a smiley face pattern on the crater. However, it is much smaller than Galle itself.
A hummocky relief resembling Veiki moraines has been found in Nereidum Montes. The relief is hypothesized to result very much like Veiki moraines from the melting of a martian glacier.
The mission
Mars Express is a space probe of the European Space Agency (ESA) launched on June 2, 2003 to study the planet Mars. This is the first exploration mission of another planet in the solar system launched by the European Agency. Mars Express is developed in a relatively short period of time by partially taking over the architecture of the Rosetta probe while five of the seven instruments were developed for the Soviet Mars 96 probe.
It was launched on June 2, 2003 by a Soyuz rocket and is in orbit around Mars on December 25 of the same year. Mars Express has obtained many scientific results: determination of the nature of polar ice caps and estimation of the volume of stored water, composition of the Martian atmosphere and its interactions with the solar wind, observation of the seasonal cycle of water , three-dimensional mapping of the reliefs, detection of hydrated minerals proving the presence of water in the past over long periods on the surface and mapping of the regions concerned, detection of the presence of water in the liquid state under the ice cap of the South Pole . The mission of an initial duration of 23 months has been extended several times and must now be completed by the end of 2020.
