NASA shares amazing Blue Dunes image on Mars

Nasa has released a stunning image from Mars showing an area covered by a sea of “blue” sand dunes.

The picture shows the sand dunes covering the planet’s northern polar cap, where temperatures can reach as low as -150C (-238F).

Nasa says the sand dunes actually cover an area the size of Texas, the second largest US state, which has an area of about 695,662 km².

The image, released for the first time on Thursday, covers an area roughly 19 miles wide, according to the Independent.

The picture was composed of several images taken from December 2002 to November 2004 by Nasa’s Mars Odyssey orbiter, which was responsible for the stunning photo.
