Pictured: Blue boulders seen on surface of Mars
Blue boulders have been seen on the surface of Mars in a vast crater believed to have been created by an asteroid.
You're viewing a single thread.
according to NASA:
Figure A: In this enhanced-color version of the mosaic, the color bands of the image have been processed to improve visual contrast and accentuate color differences.
I believe the top image on that page is natural color.
If you look at nasa's pages about this site (mount Washburn), the word "blue" never comes up. In fact they were more interested in a single white boulder that stood out to them. Another page for example.
I imagine that they're just normal grey rocks that look blue because of all of the red
that was my first thought as well, but it's actually just an altered image. I believe the top image in the first link is natural color. they just look dark gray/black even next to the orange regolith.
Not as neat as I thought. Thank you for actually looking into the details.
