LONDON: NASA has been beaming photos from space since Curiosity landed there in August 2012.
Mr White, a space video journalist from Bristol, said: ‘It is what looks like a very large rodent in Gale Crater sitting on a ridge, plain as day.
‘It may be an optical illusion but it has big ears, nose and eyes visible.
‘It resembles a very large mouse or gerbil, and would be about two or three feet long.’
Mr White runs the YouTube channel ArtAlienTV and trawls through Nasa’s images to find unusual shapes.
The ‘mouse’ image was taken using the 6ft-high (1.8 metre) right-hand side mast cam on the Curiosity rover on 27 October.
It follows the release of an image last week of a rock on Mars that is said to resemble Nabu – the god of wisdom to the Neo-Assyrians – at least according to some UFO enthusiasts.
The image was taken at a site called, Concepción Crater, an area that had been a mystery to scientists due to strange coatings on rocks near the crater.
