Beginning late on 25 May, Mars Express will execute a series of pre-programmed commands specially designed to support NASA's Phoenix lander. The ESA spacecraft will conduct a high-speed slew, enabling it to track Phoenix as it enters the Martian atmosphere.Mars Express will point its Lander Communications Antenna toward Phoenix's planned entry trajectory and record signals transmitted from the lander as it plunges toward the surface during the critical entry, descent and landing (EDL)...

Science What advantages does the Thermal and Evolved Gas Analyzer (TEGA) have over the Viking mission's Gas Chromatograph in detecting organics? The Phoenix mission has two advantages over the Viking mission with respect to organics. The first is that Phoenix is slowly heating the sample to 1000 C, whereas Viking heated very quickly to 500 C. There are many organics thought to be possibly stable on Mars that vaporize in the 700 C to 800 C range. These types of organics are often call...

Peter Smith of the University of Arizona's Lunar and Planetary Laboratory heads the Phoenix Mission, where hundreds of dedicated individuals from around the world are teaming together to explore the arctic plains of Mars. Peter Smith is supported by talented science, project management and payload management teams with a wealth of experience in Mars exploration. Science Team Principal Investigator Peter Smith is supported by a science team with experience in all previous landed Mars missions....

ESA's Mars Express mission control team are ready to monitor Phoenix's critical entry, descent and landing onto the Martian surface on 26 May 2008. The Mars Express mission control team have completed major preparations for supporting the entry, descent and landing (EDL) phase of NASA's Phoenix mission to the Red Planet. On 25 May, Mars Express will point towards Phoenix's planned entry trajectory and record signals broadcast from the lander as it plunges through the Martian...

Artificial intelligence (AI) being used at the European Space Operations Center is giving a powerful boost to ESA's Mars Express as it searches for signs of past or present life on the Red Planet.Since January 2005, Mars Express has been using its sophisticated instruments to study the atmosphere, surface and subsurface of Mars, confirming the presence of water and looking for other signatures of life on and below the Red Planet's rocky terrain.The spacecraft generates huge volumes of...

ESA's Mars Express radar sounder, MARSIS, has looked beneath the Martian surface and opened up the third dimension for planetary exploration. The technique's success is prompting scientists to think of all the other places in the Solar System where they would like to use radar sounders. No matter how accurate a camera is, it can only map a planet's surface. To retrieve information about the underground realm, planetary scientists in the past would have thought it necessary to land on the...

The towering 3-D features of Martian canyons and highlands are about to stand out like never before, thanks to data from a high-resolution camera on the Mars Express orbiter. These data, collected by the camera on the European Space Agency's Mars Express, are allowing scientists to create so-called Digital Terrain Models (DTMs) to look around the Martian surface from different directions and angles, as opposed to the usual bird's-eye view from above provided by previous Mars orbiter...

Mars is about to come into 3D focus as never before, thanks to the data from the Mars Express High Resolution Stereo Camera (HRSC). A new high-resolution Digital Terrain Model data set that is about to be released onto the Internet, will allow researchers to obtain new information about the Red Planet in 3D. Digital Terrain Models (DTMs) allow scientists to "Ëœstand' on planetary surfaces. Although ordinary images can give spectacular bird's-eye views, they can only convey part of...

On December 25, 2003, Europe's first Mars explorer arrived at the Red Planet. Almost four years later, Mars Express continues to rewrite the text books as its instruments send back a stream of images and other data. Today, the spacecraft reached another milestone in its remarkable career by completing 5000 orbits of Mars. During its mission to investigate martian mysteries, the orbiter has revolutionised our knowledge of Mars, probing every facet of the Red Planet in unprecedented detail....

With ESA's Mars Express, scientists continue to gain new insight into the mysterious Martian environment. Some of the most exciting results are being sent back by the MARSIS (Mars Advanced Radar for Subsurface and Ionospheric Sounding) experiment. MARSIS transmits low frequency radio waves towards the planet's surface and records the echoes of the different layers. Although Mars is sometimes described as the most Earth-like of all the planets, there are many differences between the two...
