And in other news, the sky is blue …

What is It?

Can you tell what you are looking at in this picture? Hint: In the dead center of the picture, look for something that doesn’t cast a shadow like anything else. Instead of a depression, look for a tiny bright spot that casts a long shadow horizontally across the moon’s surface.

Did you find it? You’re looking at the Apollo 11 Lunar Module! (Actually, it’s just the descent stage, which remained on the moon when Neil Armstrong and Buzz Aldrin took off in the ascent stage.)

The Lunar Reconnaissance Orbiter (LRO) took the picture earlier this month, along with photographs of all the other Apollo landing sites except for Apollo 12. NASA released all the photographs today.

This is a piece of news that SHOULD be about as surprising as, “Scientists today released photographic proof that the sky is blue.” Nevertheless, it is actually huge, because there has been a small but vocal contingent of people claiming in recent years that all of the Apollo moon landings were faked. They even managed to convince the Fox television network to run a special about the “moon hoax” a few years ago. It’s now going to get a lot harder for them to make their case.

The place you should go to read about all of this is Phil Plait’s wonderful blog, Bad Astronomy. Plait has run a website and a blog for years that debunks silly claims like UFOs, faces on Mars, etc. … and one of the battles that he has fought all this time is the one against the moon-hoaxers. So for him, the release of these NASA images must be a huge personal triumph.

What’s so great about it is that here is one case where the conspiracy theorists have gotten themselves trapped — they have occupied a position that can slowly, bit by bit, get chopped out from underneath them, as the LRO missions and other missions get higher- and higher-resolution pictures. This is something that we can only dream of in some of the other contentious non-debates that science has to deal with. Imagine, for example, that we could actually go back into the past and get photographic proof of evolution happening … but we’ll never be able to do that. And so the evolutionism versus creationism non-debate will go on forever. However, for the moon-hoax non-debate, I think the end may be in sight.

Now let’s put that aside, like a bad dream, and also appreciate these pictures for what they show. I love the Apollo 11 picture precisely because the Apollo 11 lander is so different from anything else in the picture. It really says, “We are the aliens here.”

Next, here is part of the photograph of the Apollo 14 landing site.

Apollo 14 Landing Site

Here the lighting was so good that you can actually see the astronauts’ footprints leading from the lander (right) to the Apollo Lunar Surface Experiments Package (left of center). Amazing! Of course, as my wife said, “Are those footprints or footprint-shaped craters?” 

Also the photograph of the Apollo 16 landing site documents another little bit of Apollo history:

In this one you can see the shadow of the lander extending all the way across a nearby crater. Apollo 16 came perilously close to landing in this crater, and the photo shows what a close call it was. Quoting from David M. Harland’s book, Exploring the Moon: The Apollo Expeditions: “They were in the centre of a subdued crater about 100 metres wide. What they did not discover until they ventured outside, was that the rear footpad was a mere 3 metres beyond the rim of the 15 metre crater that Young had lost sight of [while landing the LM]. When he had hovered to select a spot on which to land, he was directly over the crater, and had narrowly missed landing on the rim.”

Fascinating stuff, and a wonderful 40th-anniversary treat from NASA!
