The planet appears much dimmer in the sky. Great deal to its brightness, and in fact, from the vantage point of the Earth, they are not always fully on view.Ībout every 13 to 16 years, the rings are edgewise-on to the Earth's line-of-sight, when they are only seen as a thin line in telescopes - or sometimes Orbit and the Changing Aspect of the Rings Is the 'zero point' from which the longitudes of the planetsĪre measured (diagram based on a graphic by space artist David In which Saturn appears, as seen from the Earth, is shown in green.

FACE OF MARS FROM DIFFERENT ANGLE ARCHIVE
The Mars Express-HRSC DTMs are available to the science community at large through the archives at the Planetary Science Archive () at ESA and the Planetary Data System () at NASA. DTMs had been processed in the past for exclusively scientific and outreach purposes, but with additional resources now available, it is possible to release the DTM data in higher quality. The additional funding required for the special processing of the individual image swaths and for the creation of the mosaics was provided by the German space agency (DLR), to the DLR Institute for Planetary Research and the Institute for Geological Sciences of the FU Berlin.
FACE OF MARS FROM DIFFERENT ANGLE SOFTWARE
Mosaics of certain features on Mars, such as the Olympus Mons volcano, are processed at FU Berlin using DTM data of individual strips and specialised software developed within the HRSC Co-Investigator Team. The systematic orbit-by-orbit processing of the DTMs is done entirely at DLR’s Institute of Planetary Research, Berlin, which also runs the HRSC experiment for ESA‘s Mars Express on behalf of, and in cooperation with, the PI and his team at the Institute of Geological Sciences, FU Berlin. The work of deriving new high-resolution archivable DTMs is split between DLR and FU Berlin. It is the first time that high-resolution images have been accompanied by high-resolution topography. HRSC provides altitude data for every data point the camera sees. NASA’s Mars Global Surveyor carried a laser altimeter instrument (MOLA) that provided spot heights across the surface of Mars, but these were often separated by many kilometres. It therefore sees a feature coming, sees it directly underneath and watches it recede into the distance, providing all the different angles needed. To achieve its complementary views, HRSC has nine individual scan lines that point fore, aft and straight down. The High Resolution Stereo Camera (HRSC) on Mars Express is the only experiment that can do it in one pass. Most attempts to do this in the past have required the spacecraft to target the same feature from two different orbital passes. The team plans to add more data to the DTMs to extend the surface coverage as Mars Express continues its mission until at least 2009 and HRSC continues its unique scrutiny of the planet.Ĭonstructing a Digital Terrain Model requires a spacecraft to look at the same surface feature twice, each time from a different angle. “As the mission continues, we are gradually filling in the gaps and collecting high-resolution data whenever possible,” says Neukum. When it is closest to the surface, it can take the most detailed pictures. The orbit of Mars Express determines the resolution of its pictures.

The DTM elevation data derived from these images is provided in pixels of up to 50 m, with a height accuracy of 10 m. The high-resolution images used have a resolution of 10 m/pixel. The individual swaths are then put together into mosaics that cover large regions. Its release has been made possible by processing individual image swaths taken by the HRSC as Mars Express sweeps through its orbit. The Mars Express DTM is the most detailed topographic data set ever released for Mars. “Once we know where the surface is, we can correctly interpret the radar echoes we get from below it,” says former ESA scientist Angelo Rossi, a member of the HRSC team. It also helps planetary scientists to better interpret other data sets, for example the results of the Mars Advanced Radar for Subsurface and Ionosphere Sounding (MARSIS).
