Discover the immense energy of water as ESA’s Mars Categorical takes us on a flight over curving channels, streamlined islands and muddled ‘chaotic terrain’ on Mars, absorbing rover touchdown websites alongside the best way.
This lovely flight across the Oxia Palus area of Mars covers a complete space of roughly 890 000 km², greater than twice the dimensions of Germany. Central to the tour is one in every of Mars’s largest outflow channels, Ares Vallis. It stretches for greater than 1700 km and cascades down from the planet’s southern highlands to enter the lower-lying plains of Chryse Planitia.
Billions of years in the past, water surged by Ares Vallis, neighbouring Tiu Vallis, and quite a few different smaller channels, creating most of the options noticed on this area in the present day.
Benefit from the flight!
After having fun with a spectacular international view of Mars we focus in on the realm marked by the white rectangle. Our flight begins over the touchdown web site of NASA’s Pathfinder mission, whose Sojourner rover explored the floodplains of Ares Vallis for 12 weeks in 1997.
Persevering with to the south, we move over two massive craters named Masursky and Sagan. The partially eroded crater rim of Masursky particularly means that water as soon as flowed by it, from close by Tiu Vallis.
The Masurky Crater is stuffed with jumbled blocks, and you may see many extra as we flip north to Hydaspis Chaos. This ‘chaotic terrain’ is typical of areas influenced by large outflow channels. Its distinctive muddled look is assumed to come up when subsurface water is out of the blue launched from underground to the floor. The ensuing lack of assist from under causes the floor to hunch and break into blocks of assorted dimensions and shapes.
Simply past this chaotic array of blocks is Galilaei crater, which has a extremely eroded rim and a gorge carved between the crater and neighbouring channel. It’s seemingly that the crater as soon as contained a lake, which flooded out into the environment. Persevering with on, we see streamlined islands and terraced river banks, the teardrop-shaped island ‘tails’ pointing within the downstream route of the water circulation on the time.
Crossing over Ares Vallis once more, the flight brings us to the smoother terrain of Oxia Planum and the deliberate touchdown web site for ESA’s ExoMars Rosalind Franklin rover. The first aim of the mission is to seek for indicators of previous or current life on Mars, and as such, this as soon as water-flooded area is a perfect location.
Zooming out, the flight ends with a surprising chicken’s-eye view of Ares Vallis and its fascinating water-enriched neighbourhood.

How the film was made
This movie was created utilizing the Mars Categorical Excessive Decision Stereo Digital camera Mars Chart (HMC30) information, a picture mosaic comprised of single orbit observations of the High Resolution Stereo Camera (HRSC). The mosaic, centred at 12°N/330°E, is mixed with topography data from the digital terrain mannequin to generate a three-dimensional panorama.
For each second of the film, 50 separate frames are rendered following a predefined digicam path within the scene. A 3-fold vertical exaggeration has been utilized. Atmospheric results akin to clouds and haze have been added to hide the bounds of the terrain mannequin. The haze begins build up at a distance of 300 km.
The HRSC digicam on Mars Categorical is operated by the German Aerospace Middle (DLR). The systematic processing of the digicam information befell on the DLR Institute for Planetary Analysis in Berlin-Adlershof. The working group of Planetary Science and Distant Sensing at Freie Universität Berlin used the information to create the movie.
