Why are the photos and videos from the Moon mostly black and white?12 13. 09. 2022
In 1994, NASA sent a spacecraft to the Moon with the nickname "Clementine". The mission was to photograph the Moon digitally in natural colors with very high resolution. (You can verify this at Wiki.) The resulting effect is that you will find low-resolution photos on the Internet (1 inch on the screen corresponds to 5 km). You can check it out on the official website with photos of the Moon from NASA. Interestingly, it's in the * .mil domain, which means that the photographs fall under the US Army and, as we already know, NASA is a military institution.
Version browser, which can be viewed by Moon photos at this time, is 2.0b. When you search for google Clementine Mission Borwser you will find it relatively recent upgrade.
The 1.5 map version had a 1 pixel resolution per kilometer. In addition, it turns out that NASA specialists again played with a graphic editor. The buildings and structures that are on the Moon are clearly outlined in different places. In the 2.0 version, the work of destruction was completed. Place blur they obviously used it Types a tool that is hidden beneath the icon stamp. Its function is to copy a specific pixel area to the specified location. This can virtually delete anything from a photo. If the photo is even shrinking and gently blurring, the resulting effect is absolutely perfect.
And that greengrocers did not spare with blur is evident on the official website. :)
You may think, "... but when I look at the moon in the sky, it looks gray!"
You're right, but you have to realize that the moon is lit by a very powerful lightbulb on behalf of the Sun and the fact that we look at the Moon through the atmosphere that works as a filter. The moon is overwhelmed against the black background. The human eye is not capable of such differentiation.
Na Wikipedia this link contains external links Astricie Month. In the gallery of this website you can find a remarkable thing - a photo of the Moon in color. From the commentary we learn that it is not about natural colors, but about the composition of two photographs with ultra and infra spectra. The author of the article states that the colors of the Moon can also be observed in a telescope and photographed with a better digital camera.
It is also worth mentioning Alan Bean. Alan Bean is an American astronaut who participated in the mission Apollo 12 for a month. His next profession is painting. On video presented by Richard Hoalgland (a former NASA consultant during the Apollo program) shows a few paintings that the astronaut presented with the words: "this is how I imagine the Moon'. The paintings are of course colorful.
I have even managed to find a page that contains saved map data from Clementine in the 1.5 version, the version where you can see the graphics editor's work. While the page itself is in English, but the most important are photos: Clementine Lunar Image Browser 1.5. A few examples in the gallery:
