Mars Express 10 years at Mars: Observations by the Mars Express Radio Science Experiment (MaRS)

Planetary and Space Science, 2016
The Mars Express spacecraft is operating in Mars orbit since early 2004. The Mars Express Radio Science Experiment (MaRS) employs the spacecraft and ground station radio systems (i) to conduct radio occultations of the atmosphere and ionosphere to obtain vertical profiles of temperature, pressure, neutral number densities and electron density, (ii) to ...

Mars Express investigations of Phobos and Deimos

Planetary and Space Science, 2014
The Mars Express mission was launched in June 2003 and was inserted into orbit around Mars in December 2003. Its main objective is to study the Mars' subsurface, surface, atmosphere and interaction with the solar wind. A secondary objective is to study the martian moons, in particular the largest one Phobos, thanks to a near polar and elliptical orbit ...

Mars Surface Diversity as Revealed by the OMEGA/Mars Express Observations

Science, 2005
The Observatoire pour la Minéralogie, l'Eau, les Glaces, et l'Activité (OMEGA) investigation, on board the European Space Agency Mars Express mission, is mapping the surface composition of Mars at a 0.3- to 5-kilometer resolution by means of visible–near-infrared hyperspectral reflectance imagery.

Water vapor mapping on Mars using OMEGA/Mars Express

Planetary and Space Science, 2007
Abstract A systematic mapping of water vapor on Mars has been achieved using the imaging spectrometer OMEGA aboard the Mars Express spacecraft, using the depth of the 2.6 μm (ν1, ν3) band of H2O. We report results obtained during two periods: (1) Ls=330–40° (January–June 2004), before and after the equinox, and (2) Ls=90–125°, which correspond to ...

Mars Express and MARSIS

Space Science Reviews, 2004
The Mars Express mission to be launched in 2003 will provide high resolution measurements of the Martian atmosphere and ionosphere. The neutral density, temperature, and composition will be measured, and MARSIS, a low frequency radar experiment, will probe the Martian plasma environment for electron densities in the range from 100 to 3 x 105 electrons ...

Sulfates in the North Polar Region of Mars Detected by OMEGA/Mars Express

Science, 2005
The Observatoire pour la Minéralogie, l'Eau, les Glaces, et l'Activité (OMEGA) imaging spectrometer observed the northern circumpolar regions of Mars at a resolution of a few kilometers. An extended region at 240°E, 85°N, with an area of 60 kilometers by 200 kilometers, exhibits absorptions at wavelengths of 1.45, 1.75, 1.94, 2.22, 2.26, and 2.48 ...

Mars express orbit design

Acta Astronautica, 2003
Abstract This paper gives a survey of the orbit design, mission analysis aspects for Mars Express, the ESA mission to Mars. The emphasis is on those features which are unconventional. These are: the launch window with only 9 flight programs on the Fregat launcher upper stage for 30 launch days, and the re-targeting and Planetary protection strategy ...

Mars Express—ESA's first mission to planet Mars

Acta Astronautica, 2003
Abstract ESA’ Mars Express mission is a fully approved and funded project which has entered its spacecraft development (i.e. hardware) phase early January 2000. It is the first of ESA's new ‘F’ (flexible) missions which are based on a new implementation scenario to maintain overall mission cost below a stringent cost cap.

Mars Express Mission and Astrobiology*

Solar System Research, 2002
A short description of the ESA Mars Express mission planned for 2003 is given. The main goal of the mission is to look for traces of life with direct (in situ) or indirect (from orbit) measurements. The Isidis Planitia area was preliminary selected to be the landing site of Beagle-2, a small lander module for geologic, meteorologic, and exobiologic ...
