This image of Aram Chaos was taken on April 1, 2018 by the High Resolution Imaging Science Experiment (HiRISE).Within this 280 km diameter crater are large amounts of iron oxide, hematite, and silicates that form only in the presence of water, indicating that Aram Chaos was formerly a lake.According to scientists, 2.5 billion years ago, some “catastrophic” water spills from underground have carved huge river… Read More »Rock outcrops of light-colored material and stratified deposits

According to research just published in the Journal of Geophysical Research, the remains of hundreds of ancient sand dunes partially cemented by water action have been discovered in the Hellas Basin and Noctis Labyrinthus.The floods that invaded these ancient sand dunes occurred about 2 billion years ago, contributing to the partial cementing of the base of the dunes.These remnants of ancient dunes provide us with… Read More »Discovered the “ghost dunes” on Mars

Anthony Wesley has long been known as a great astrophotographer, with a 55.3 cm diameter telescope to boot!Again, the tops of large volcanoes, the south polar cap, the cloudy “collar” surrounding the north pole and another formation at the edge of the south polar cap are barely visible.Click on the image itself for more technical information…..

A beautiful article that describes the entire onset of the sandstorm that still envelops the entire surface of the planet Mars. Here you will find data and information difficult to find elsewhere and that also open several questions about the dynamics of such storms.For the moment Opportunity does not respond, but this does not surprise the technicians even if it obviously worries them; more time… Read More »Mars Exploration Rovers Update: Opportunity sleeps while storm chasers study the blanket of dust covering the entire planet

In this animation, Damian Peach shows us his photo of Mars “fading” with a simulated image of what it would have looked like in the absence of the storm.Notice how only the tops of the large volcanoes make it through the dust-laden atmosphere; also note the south polar cap (below) as well as the blue-white clouds that are instead condensations of water ice crystals!

To the side of the photo is a simulation of what it should have looked like.As you can see from the comparison, the global sandstorm makes it unrecognizable!Also note the large blue-white formation in the lower left edge of the planet just above the south polar cap; it looks like it could be a water ice cloud!
