This image shows what appears to be a large patch of fresh, untrodden snow – a dream for any lover of the holiday season. However, it’s a little too distant for a last-minute winter getaway: this feature, known as Korolev crater, is found on Mars, and is shown here in beautiful detail as seen by Mars Express.

Launched 15 years ago by the European Space Agency (ESA), Mars Express often focuses on glaciers and ice in the Martian polar regions.
