After Perseverance captured Ingenuity's third flight, Justin Maki, an imaging scientist at Jet Propulsion Laboratory, led the team that stitched the images into a video. The video frames were then reprojected to maximize viewing in an anaglyph, which is a 3D image seen through color-filtered glasses.
Justin Maki has been making 3D images of the Red Planet since 1997 when he was processing images from NASA's Sojourner, the first Mars rover. However, this is the first time he has produced 3D footage of a rotorcraft flying on Mars. The helicopter videos are the most detailed 3D videos produced by the Mastcam-Z team to date.
If you don't have any 3D glasses around, rest assured, NASA's also teaching you how to DIY your own. You can simply cut the shape of the glasses from a cardstock or poster board, including the holes for the eyes, then take one cyan-color cellophane and one red-color cellophane and cover the eyeholes. Now you can enjoy the little helicopter's historic moment!
