Discover the immense energy of water as ESA’s Mars Specific 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 stunning 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 considered one 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 way of Ares Vallis, neighbouring Tiu Vallis, and quite a few different smaller channels, creating lots of the options noticed on this area immediately.
Benefit from the flight!
After having fun with a spectacular world view of Mars we focus in on the world marked by the white rectangle. Our flight begins over the touchdown website 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 cross over two giant craters named Masursky and Sagan. The partially eroded crater rim of Masursky specifically means that water as soon as flowed by way of it, from close by Tiu Vallis.
The Masurky Crater is full of jumbled blocks, and you’ll 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 abruptly launched from underground to the floor. The ensuing lack of assist from beneath causes the floor to hunch and break into blocks of assorted styles and sizes.
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 probably 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 path of the water move on the time.
Crossing over Ares Vallis once more, the flight brings us to the smoother terrain of Oxia Planum and the deliberate touchdown website 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 hen’s-eye view of Ares Vallis and its fascinating water-enriched neighbourhood.

How the film was made
This movie was created utilizing the Mars Specific Excessive Decision Stereo Digital camera Mars Chart (HMC30) information, a picture mosaic produced from single orbit observations of the Excessive Decision Stereo Digital 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 digital camera 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 digital camera on Mars Specific is operated by the German Aerospace Middle (DLR). The systematic processing of the digital camera information passed off 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 info to create the movie.
