Putorana Plateau, Siberia

Sentinel-2A brings us over the snowy landscape of the Putorana Plateau in northern Central Siberia.

The area pictured shows part of the Putoransky State Nature Reserve, which is listed as a UNESCO World Heritage Site. Situated about 100 km north of the Arctic Circle, the site serves as a major reindeer migration route – an increasingly rare natural phenomenon – and is one of the very few centres of plant species richness in the Arctic.

Virtually untouched by human influence, this isolated mountain range includes pristine forests and cold-water lake and river systems. The lakes are characterised by elongated, fjord-like shapes, such as Lake Ayan in the upper-central part of the image.

Zooming in on the lake we can see that it is mostly ice-covered, with small patches of water peeking through around its lower reaches.

Another feature of this area are the flat-topped mountains, formed by a geological process called ‘plume volcanism’: a large body of magma seeped through Earth’s surface and formed a blanket of basalt kilometres thick. Over time, cracks in the rock filled with water and eroded into the rivers and lakes we see today.

This image, also featured on the Earth from Space video programme, was captured on 2 March 2016 by the Copernicus Sentinel-2A satellite.

Zooming in on Schiaparelli components on Mars

Zooming in on Schiaparelli components on Mars

NASA’s Mars Reconnaissance Orbiter High Resolution Imaging Science Experiment (HiRISE) imaged the ExoMars Schiaparelli module’s landing site on 25 October 2016, following the module’s arrival at Mars on 19 October.

The zoomed insets provide close-up views of what are thought to be several different hardware components associated with the module’s descent to the martian surface. These are interpreted as the front heatshield, the parachute and the rear heatshield to which the parachute is still attached, and the impact site of the module itself.

In the image, north is up; west to the left. Schiaparelli was travelling from west to east. The image scale is 29.5 cm/pixel. The brightness of the individual zooms have been adjusted to best reveal the features against the martian surface in each case.

The 100 m scale bar in the main image is only indicative, as the HiRISE image was taken at an oblique angle. The distances given between the various components in the main text have been corrected for this effect.

Three sites relating to Schiaparelli can be identified in this image, as indicated in the annotated version here.
