I see we have a full lunar eclipse coming on Feb 20/21 (depending where you live).
I know that even during a full eclipse the Moon is still visible with a coppery hue, due to the refraction of light around the Earth. Now that we have a bunch of probes in orbit of the Moon, is there any plan / is it possible to take an image of the Earth from the Moon during totality? (or has this already been done?) I would think that a picture of the Earth surrounded by a red ring would be amazing! |

Surveyor III was able to get some variously filtered images of an eclipse in 1966. One color-composite version is shown here. Of course, HDTV would be Really Cool if it can be done... |

"Surveyor III was able to get some variously filtered images of an eclipse in 1966. One color-composite version is shown" A couple years <or decades, it feels like now> I posted here a considerably improved pair of the Surveyor 3 images, reassembled from good quality black and white color separations published in JPL TR series reports on Surveyor. The image linked to had massive overexposure saturating part of the bright limb and "blooming" of the overexposed image on the vidicon detector. The original NASA Press Release image was horrible, even given that data's blooming problem. The other image was actually the much better image but was never press released in color. In my reconstruction, you can see parts of the faint blue ring of upper atmospheric scattering of sunlight with orange-red blobs where gaps in clouds on the limb let direct sunlight get refracted around the limb to reach the camera. I've tried poking around the archives here and I don't find the post. It's not on my internetting computer at the moment, so I'll have to dig for it. |
