Mars in 3-D !


Now two views. Thank you Damian Peach. The top one with half hour separation.

You CAN free view this in 3-D !!!

Ace Astrophotographer Damian Peach was kind enough to send me a different pair of images of Mars to mount as a stereo pair (the top pair – 5th June).

This time the time elapsed between exposures was – as you can see from the small grey time logs underneath – almost exactly half an hour. Now Mars spins on its axis once every 24 and a half hours – almost exactly the same as the Earth’s day. So in half an hour it’s rotated about 8 degrees. This gives us a stereo baseline twice as big as for the the bottom pair of images – and to my eyes the effect is much better – the planet really does look like a ball. You think ?! The top image shows – high up on the left limb – the biggest volcano in the Solar System – Olympus Mons – nearly three times as high as Mount Everest – and 100 times bigger across than any volcano on Earth.
