Mars's "hairy blue spider" is one of the coolest new scenes shot by the European Orbite



False-colored image of the traces of the dust of the devil gives a clear appearance of the tarantula on the Martian surface. a new image of what looks like a giant blue tarantula on the surface of Mars. In fact, the fake color picture shows a series of paths produced by Martian dust devils. The photo is one of many, shot by the ExoMars Trace Gas orchestra in Europe, some of which were released today for viewing pleasure.

The Orbiter of ExoMars Trace Gas (TGO) arrived on Mars in October 2016, its low orbit on a planet-skipping until February 2018, with scientific operations beginning a few months later. This project is run by the European Space Agency (ESA) and Roscosmos and its main mission is to hunt down trace gases like methane to help scientists better understand the capacity of the Red Planet – or former capacity – to promote life .

But TGO arrived on Mars with a pretty good camera, known as the Surface Imaging System (CaSSIS), which he used to explore the Martian surface from orbit. CaSSIS is unique in that it can use its camera to produce high-quality, crystal clear 3D images in addition to conventional 2D images. A new set of photos published today is a good example of what TGO can do.

A fake-colored photo of the Terra Sabaea area on Mars shows many superficial features on the surface. In fact, these are the traces left by the dust devils, a common phenomenon on Mars. This model is seen on the crest of the ridge, and this is "essentially the convergence of hundreds or perhaps even thousands of smaller Martian tornadoes," according to ESA. The image is shown in a color composite view to derive the surface characteristics. Its true color, say from the ESA, will be dark red, as the powders expose fresh material below the surface.

TGO also noticed the landing of NASA's InSight, which was previously shot by NASA. This is the first shot taken by InSight from ExoMars and marks the first time a European probe that noticed a landing on Mars, according to an ESA report. This gray scale image was made on March 2, 2019, just at the same time that the probe was knocking, though shamelessly, on the Martian surface (the digger dug into an obvious rock and NASA is currently trying to figure out what to do … and no, the download method is not an option

The image shows an area slightly larger than 2 square kilometers InSight is a small spot in the dark spot, the last of which is produced by touch probe revolutions. the parachute of the spacecraft can be seen nearby TGO and InSight are teammates

"TGO is used to transmit data from InSight to Earth," said Nicholas Thomas, chief research officer of CaSSIS, in the Bern University Press release. "Because of this feature, we have not been able to direct the camera to the landing site – we had to wait until the landing site passes directly under the spacecraft to get that image. "

The activity taken from InSight's seismometer, may be a sign that the meteorite has crashed nearby. If this happens, CGO will follow the connected crater.

Other images include the edge of a masonry burrow in the crater of Burroughs near the Martian South Pole. Dust and ice form layers in the crater for hundreds of millions of years, although the origin of the ice in the crater is somewhat a mystery.

The image above shows a 1 kilometer crater within the 100-kilometer crater Columbus, located in the southern hemisphere of Mars. The light strip at the bottom of the image is composed of various hydrated minerals, including sulphate salts.

Other photos published today show new surface features, polar layers, dunes and landscapes with dynamic topologies that scientists will use to decipher the geological history of Mars. Some of them are also in a stereoscopic view, so the 3D glasses explode.
