APOD: Apollo 11 Landing Panorama (2022 Jul 23)

Post by APOD Robot » Sat Jul 23, 2022 4:05 am

Image Apollo 11 Landing Panorama

Explanation: Have you seen a panorama from another world lately? Assembled from high-resolution scans of the original film frames, this one sweeps across the magnificent desolation of the Apollo 11 landing site on the Moon's Sea of Tranquility. The images were taken by Neil Armstrong looking out his window of the Eagle Lunar Module shortly after the July 20, 1969 landing. The frame at the far left (AS11-37-5449) is the first picture taken by a person on another world. Toward the south, thruster nozzles can be seen in the foreground on the left, while at the right, the shadow of the Eagle is visible to the west. For scale, the large, shallow crater on the right has a diameter of about 12 meters. Frames taken from the Lunar Module windows about an hour and a half after landing, before walking on the lunar surface, were intended to initially document the landing site in case an early departure was necessary.

Was any special filtering required on the camera lens - the UV (and x-rays ?) would be ferocious ?
And for the humans ...

The "Assembled from high-resolution scans" link leads to an Apollo 11 Multimedia Library. Quite a photo documentation of the Apollo 11 event.

It would be an awesome feeling seeing Earth fade away; watching
as your spaceship took out to the vast emptiness of space! 8-)

As the primary intent here is aesthetic, it would make sense to remove the fiducials (which could certainly be helpful in producing the panorama, but serve no purpose in the final image, are distracting, and are trivially removed).

Lenses don't allow much UV to pass, and the films weren't particularly sensitive to it. So not an issue. X-rays would be more likely to hit the film through the camera structure as opposed to the lens. But most of the radiation is soft enough that it won't penetrate that deeply into a camera.

thought exercise. This scene and location will no doubt will be a museum site in the distant future. Probably the MOST FAMOUS space museum in the Solar System. Whether it is 150 years in the future or 500 years. Tourist will flock there just like they flock to the Pyramids of Giza or to Mecca today. I wonder what they will do to keep the future tourists footprints off the ground from contaminating Armstrong and Aldrins footprints? Perhaps build floating antigravity walkways with glass bottoms so the tourist can look at Armstrongs footprint close up.. Who knows but anyways a photograph of the site 500 years from now will make the view really unimaginably different then what we see today!

The most common scifi scenario has the area walled off or domed over, with views through windows.

"X-rays would be more likely to hit the film through the camera structure as opposed to the lens." - and why is that? Because the moon would be blocking them from the direction of the lens?

PixInsight? Even more noticeable fiducials are visible in that other linked-to APOD as well.

For that I just used Photoshop. Selected one of the fiducials, saved the selection, and repeatedly placed the selection over the remaining ones and used the context-aware fill tool. Didn't take five minutes.

More likely they will do that after space influencers and DimbDumb*-kids ruined the place for cheap shots. Then the place will have to be elaborately restored after protests of the public and then put under the protective cover.

I guess Photoshop is smart enough to do a "select by contiguous color" or some such thing? I've never used PS - all I have is GIMP. and I find that to be as unintuitive as it gets.

I manually drew the selection area, then used that selection repeatedly. Photoshop's context-aware fill is semi-miraculous. It constructs new pixels based on the structure that is outside the selection area. Most of the time it does it extremely well. And in an image like this, where so few pixels are being modified, artifacts are well below our normal perceptual ability.

Except maybe for universes. From https://bigthink.com/videos/a-universe-is-a-free-lunch/. It’s Michio Kaku’s popularization attempt, but his source is probably Alan Guth (one of the fathers of The Inflationary Theory of the Universe - https://en.wikipedia.org/wiki/Inflation_(cosmology):
How can you create a universe from nothing? Well if you calculate the total matter of the universe it is positive. If you calculate the total energy of the universe it is negative because of gravity. Gravity has negative energy. When you add the two together what do you get? Zero, so it takes no energy to create a universe. Universes are for free. A universe is a free lunch. And then you may say to yourself well that can't be right because positive and negative charges don't cancel out, therefore, how can the universe be made out of nothing. Well if you calculate the total amount of positive charge in the universe and calculate the total amount of negative charge in the universe and you add it up what do you get? Zero, the universe has zero charge. Well what about spin? Galaxies spin, right? But they spin in all directions. If you add up all the spins of the galaxies what do you get? Zero, so in other words, the universe has zero spin, zero charge and zero matter energy content. In other words, the universe is for free.
