To celebrate the winter solstice on Earth and the start of winter in the northern hemisphere, NASA has released some photos captured on Mars by its Mars Reconnaissance Orbiter space probe’s HiRISE camera showing what some Martian areas look like when it’s winter on the red planet. Seeing snowfall is still beyond the possibilities of the available instruments but frozen or at least frost-covered landscapes show some of the marvels of Mars.
