Latest Hellas Planitia Stories
The surface of Mars is pocked and scarred with giant impact craters and rocky ridges, as shown in this new image from ESA’s Mars Express that borders the giant Hellas basin in the planet’s southern hemisphere.
A newly released image from the ESA offered a groundbreaking peek under the surface of Mars courtesy of the Mars Express orbiter.
The European Space Agency's Mars Express has offered up a high-resolution photo of a river-like structure on Mars. The spacecraft used its high-resolution stereo camera last year to snap an image of Reull Vallis on the Red Planet.
Scientists have found further evidence that massive seas once existed on Mars.
The Mars Express High Resolution Stereo Camera imaged a region close to Maâ€™adim Vallis, one of the largest canyons on Mars, finding craters, lava flows and tectonic features.
NASA's Mars Reconnaissance Orbiter has revealed vast Martian glaciers of water ice under protective blankets of rocky debris at much lower latitudes than any ice previously identified on the Red Planet.
Scientists are now able to better explain why Marsâ€™s residual southern ice cap is misplaced, thanks to data from ESAâ€™s Mars Express spacecraft - the martian weather system is to blame. And so is the largest impact crater on Mars â€“ even though it is nowhere near the south pole.
New analysis of Mars' terrain using NASA spacecraft observations reveals what appears to be by far the largest impact crater ever found in the solar system.
