Watch the Moon in 3D

And how NASA's Moon orbiter pulls it off with a single camera.

Put on your 3D glasses to see our Moon up-close in glorious depth. 😎️

This stereographic 3D image of the Moon was made from images captured by NASA’s Lunar Reconnaissance Orbiter (LRO). NASA has made thousands of stereo images available as part of LRO’s data release. Browsing through a bunch of them, I found some really cool and intriguing Moon features that look surreal in 3D. So I cleaned them up for public consumption and made a video out of it, touring different places on the Moon.

Here’s are two sample images from the video.

How does NASA LRO capture 3D images?

LRO pull off the feat using a single camera. As it passes above a feature of interest, it tilts itself by a certain degree and snaps an image as per pre-sent commands by missions operators on Earth. As the same feature comes into view about two hours later in the next orbit, LRO is made to tilt again, this time in the opposite direction to get another image. These two images are then processed here on Earth to make stereographic images just like we do for 3D movies.

With this method, LRO mission designers took advantage of the fact that the Moon rotates slowly about itself––once every 27 days. A spacecraft in a similar orbit around Earth or Mars, both of which rotate much faster, would have to wait quite a while for a feature of interest to be in view again.
