Any idea of the scale of that image? What is the diameter of the crater?
- Isinlor 6y ago2000 km, so I guess somewhere around the size of India. https://en.wikipedia.org/wiki/Vastitas_Borealis https://en.wikipedia.org/wiki/Vastitas_Borealis @edit - 2000km is the size of the whole region, crater is 35 km wide. See below.
- ckarmann 6y ago2000km is the size of the whole Vastitas Borealis region. The photo depicts only a single unnamed crater inside it.
- Isinlor 6y agoIndeed, my bad. Seems to be easy to confuse since the crater seems to have the same name "Vastitas Borealis Crater" [0]. Do you know if it's actually called "Vastitas Borealis Crater" or is it just simply a crater in the region Vastitas Borealis? > The 35-kilometre-wide crater sits 70° north of the martian equator, in a low-lying region known as Vastitas Borealis. Previous orbiters have spotted ice deposits in craters, but the High Resolution Stereo Camera on board the European probe is the first to return a three-dimensional colour image of an icy spot. The ice may be up to 200 metres thick, and lies over a dune field that has formed in the sediment on the crater's floor. The data were collected on 2 February, and this image was created for Nature last week.

- ckarmann 6y agoI don't think this one has a specific name. There are a lot of unnamed craters on Mars, even much bigger than this one. [0] [0] https://en.wikipedia.org/wiki/List_of_craters_on_Mars https://en.wikipedia.org/wiki/List_of_craters_on_Mars
