Superb 3D panorama image of a Lunar Module interior here:

https://airandspace.si.edu/explore-and-learn/multimedia/vr?passthrough=/files_special/Panos/A19711598000_1

This is a Lunar Module (designated LM-2) that was built for a rerun of Apollo 5 that never happened, hence there still exists one example of the real thing. The others were either crashed onto the Moon or burned up in Earth's atmosphere once they'd fulfilled their purpose.

The door to the surface of the Moon is at the front,under the main instrument panel. Imagine opening that and peering down onto the grey, dusty, pitted surface of another world.

My first thought about this was that it seems like a lucky near miss - what would happen if it collided with Earth instead of just being captured by the planetary gravity for a bit?

But apparently it's only roughly the size of a bus, and would likely break up and explode in the atmosphere.

In 2013 a meteor exploded 30km above Russia with a 500 kiloton blast, but it was much bigger (14,000 tonnes) and even that wasn't close to an "extinction event".

I read something recently about the real danger being the asteroids in this belt sometimes collide with each other and if that nudge deflects the orbit of something of a troublesome size, it could spell danger for the Earth. I suppose given sufficient time it's inevitable there will be some calamity.

The Chinese brought some Moon stuff back to Earth in 2020, and a bit of it will be studied in the UK.

It's the first lunar sample we've had since the '70s. One interesting thing is that it comes from a relatively "young" region. Most of the Moon's surface is shaped by ancient volcanic activity and meteorite impacts. But the region where these Chinese samples have been taken is less than 2 billion years old, ie flooded by lava much later than the Apollo sites.

Apparently this was worked out by counting the craters and applying a bit of statistics. Fascinating. But the returned samples have confirmed it.

https://www.bbc.co.uk/news/articles/c4g3krykxypo

In the BBC article the contents of the little vial are described as "more precious than gold dust" which when you consider the expense of getting hold of it and its value to science, seems a ridiculous understatement.

The Chinese mission collected 1.7kg of the stuff. We now have 60mg of it in a safe in Milton Keynes. A bif of googling tells me that 60mg of gold dust would cost about 10p.

The return of the Moon samples was the primary goal of China's Chang'e 5 mission. It probably cost about $1.2 billion. They got 1.73kg so on that basis, 60mg of the stuff was acquired at a cost of $41,618.

Love the story of the US astronauts preparing for the moon landings in the 1960s.  As part of the training they had to head out to some inhospitable terrain and practice manoeuvres in space suits. (A bit odd I know as there's nowhere on land with the low gravity of the Moon but I'm sure some value was obtained)

Anyway their operation piqued the interest of the local native American tribe. The Chief approached them and asked what they were doing. They explained about the Apollo mission and their plan to land on the Moon.

The Chief said "The Moon? Our Spirit brethren live on the Moon. Would you be able to deliver a message to them".

"A message? Certainly! What would you like to say"

The Chief said a phrase in his local tongue and got the astronaut to repeat it until it was word perfect.

"What am I saying?" asked the astronaut

"I cannot say" replied the Chief. "They are sacred words that only the tribe and our spirits can understand"

As soon as the training was complete the astronaut rushed to find a translator who knew the tribe's language.

"What am I being asked to relay to their spirits" he asked.

The translator did his best to suppress his laughter as he delivered the translation.

" Do not trust these people. They will steal your land"

Another very clear night so with the Moon in a bit of shadow at the edge, I thought I'd get another pic.

I used exactly the same camera / 200mm fixed focal length lens combination. But the Moon is noticeably smaller tonight - all the Moon images I've posted in this thread are cropped, but not resized.

Title: Re: The Moon
Post by: Slim on January 05, 2026, 10:54:42 PM
I was intrigued by this, so I used this site: https://dqydj.com/lunar-distance-calculator/ - to check the distances from my location on Earth to the Moon at the times the photos were taken.

3/1/26 9pm : 370022 km
5/1/26 9pm : 377975 km

(https://i.ibb.co/7dWrZZqC/twomoons.avif)

So the first distance is 0.979 x the second (to within 3 decimal places).

This being the case, the pixel diameter of the Moon in the second image should be close to 0.979 x the pixel diameter of the first. I measured them in the GIMP.

436 pixels in the first, 427 in the second.

427 / 436 = 0.979.

Science!

Just bought this bad boy from a 35mm film camera specialist. It's a 500mm mirror lens, probably made in the late '70s, early '80s. Excellent nick. Should arrive tomorrow.

Not as good as a standard, modern "non-mirror" lens but much less expensive (I paid £100). Will provide Moon images about 2.5x the size of the 200mm lens (also an ancient film camera lens) but more importantly a bit more detail. Just have to wait for another clear night!

Finally a clear evening with the Moon up, so I had a chance to have a go with the 500mm lens. Used a proper tripod this time. Not sure it improves on the 200mm to be honest! Although the image is larger (downsized here) I think the 200mm is a bit sharper.

I've concluded now that the 500mm does provide better detail, just, than the 200mm. The 200mm is better glass and not compromised by being a mirror lens. But the brute force magnification of the 500 just about overcomes that.

The critical thing is to get the focus just right. For a manual focus lens on an SLR intended to take autofocus lenses, that's not particularly easy, especially when the camera is pointing upward and you have to get under it to squint through the eyepiece or examine the preview screen.

Apparently my K-S1 has HDMI out so I could, at a pinch, take a monitor out onto the patio. Will test that I think. Just ordered a micro-HDMI cable from Amazon.
