InSight: what NASA’s mission to Mars could find inside the Red Planet
Follow Ken on Facebook and Twitter. THAT is just so way double extre groovy cool and way beyond simple synchronicity! I like! So what's up with that? Early on I read reports that said the Mars Orbiters would all be placed in 'standby' mode, with whatever mass available pointed in the direction of travel to shield against cometary micro meteor bits and dust.
Is that still the case?
One of the clearest signs of global warming, unless you live next to a glacier, are rising oceans. Now a….

This color-coded topographic view shows a dried-up river valley on Mars named Nirgal Vallis. Lower parts of the surface are shown in blues and purples, while higher altitude regions show up in whites, yellows, and reds, as indicated on the scale to the top right.
Despite the arid, hostile world we see today, Mars is thought to have once been a far warmer and wetter planet — and we see signs of this in the diverse mix of features and minerals found across its surface. As there appear to be no branching, tree-like tributaries feeding into the main valley of Nirgal Vallis, it is likely that water was replenished on ancient Mars by a mix of precipitation and overland flow from the surrounding terrain.
We see this kind of mechanism on Earth in environments where surface material is very fine and loose and thus difficult for water to penetrate — largely silty, sandy, unconsolidated, and fine-grained environments, where lower layers of the surface are permeable and friendlier to water than those above.
Its aim — of characterizing and understanding the Red Planet in its entirety — will be supported and continued by the ESA-Roscosmos ExoMars Trace Gas Orbiter, which arrived at Mars in , and the ExoMars Rosalind Franklin rover and its accompanying surface science platform, which will arrive next year. Together, this ground-breaking fleet will help unlock the mysteries of Mars.

The spacecraft has sent back myriad breathtaking images of our planetary neighbor in the past decade and a half, captured by the probe's on-board HRSC High Resolution Stereo Camera — and this image is no different.
It comprises data gathered on 17 June during orbit This image was created using data from the nadir and color channels of the HRSC. Visible at the top of the frame is Mars' ethereal north pole: this is permanently covered by a cap of frozen water and carbon dioxide, which thickens in the northern martian winter and thins in the summer. As this image shows, this patch of Mars is a mix of different tones and colors — a reflection of the different chemical and physical characteristics of the material that makes up the surface.
Mars' two hemispheres are very different in a number of ways.

The northern hemisphere is also characterized by low-lying plains that are largely unmarked by impact craters and thus thought to be relatively young, while the southern hemisphere is ancient, showing signs of intense cratering. Figure Topographic context. This color-coded topographic image shows a slice of the Red Planet from the northern polar cap downwards, and highlights cratered, pockmarked swathes of the Terra Sabaea and Arabia Terra regions.
The area outlined in the center of the image indicates the area imaged by the Mars Express High Resolution Stereo Camera on 17 June during orbit Below this, in tones ranging from rusty orange to pale butterscotch, are the southern highlands, featuring more craters than it is possible to count. Did the planet's crust once comprise various moving tectonic plates, as we see on Earth, that pushed against one another to form the dichotomy?
Could it have been created by one or more colossal past impacts — or by another process entirely? Mars is thought to have seen various bursts of glacial activity over the years, where deposits of ice — sometimes hidden beneath layers of soil or dust — form viscous flows that slowly move across the surface, altering it as they go. Mars Express and the TGO will soon welcome the ExoMars Rosalind Franklin rover and its accompanying surface science platform, which are scheduled for launch in July of This image shows a slice of the Red Planet from the northern polar cap downwards, and highlights cratered, pockmarked swathes of the Terra Sabaea and Arabia Terra regions.
Up close, however, the planet is actually covered in all manner of colors — from bright whites and dark blacks to yellows, reds, greens, and the cappuccino tones seen here. It comprises data gathered on 11 December during Mars Express orbit They are undeniably visually striking, but also reveal a significant amount about the composition and properties of the surface material itself.
The lighter patches to the left south are instead largely covered in fine silicate dust.
Figure Perspective view of Terra Cimmeria. This oblique perspective view was generated using a digital terrain model and Mars Express data gathered on 11 December during Mars Express Orbit The planet hosts some of the largest volcanoes in the Solar System, including the very biggest, Olympus Mons, and has several notable volcanic provinces two of which are Tharsis and Elysium. The volcanoes within these regions once released ash and dust that covered and coated the surface of Mars, forming dark basaltic sands that were swept around and covered up by other material over time.
These valleys spread across Terra Cimmeria, once moving water and material throughout the area.
Dust devils form as eddies of wind that displace the top layer of dust from the martian surface, sending it swirling up into the air. This in turn reveals a deeper layer of material that is different in color, creating a sharp visible contrast. These form in a similar way to dust devil tracks, except that they are caused not by eddies, but by local winds being forced over topographic features such as craters or cliffs. Wind streaks are useful indicators in atmospheric studies; for instance, the wind that formed the streaks in this image was blowing in a roughly south-easterly direction given that north is to the right.

The illumination angle of the Sun changes between image frames, highlighting the structures in the dust clouds. ESA's Mars Express observed at least eight different storms at the edge of the ice cap between 22 May and 10 June, which formed and dissipated very quickly, between one and three days. Figure 29 : Dust storm season on Mars. Between late May and early June, several different irregular- and spiral-shaped dust storms were seen to be building up at the north polar ice cap of Mars.
The long image strips cover an area of about two thousand by five thousand kilometers, extending from the north pole equatorward to the large volcanoes Olympus Mons and Elysium Mons. In the latter case, the cameras watched the storm evolve until 10 June, as it moved southward towards the volcanoes. Wispy patches of light-colored clouds can be seen at the outer margin of the polar cap and also several thousand kilometers away, close to the Elysium volcanoes. At the same time, wispy clouds can be seen along the edge of the ice cap, and also further south left around the large volcanoes.

This particular storm started on 28 May and continued to around 1 June, moving towards the equator during that time. In the latter case, the cameras watched the storm evolve for several days as it moved in an equatorward direction. Some traces of dust and clouds remained in the volcanic province into mid-June.
