Quite a bit more, I’d say a few degrees.

It doesn’t.. but even if it did, what’s more important, astronomy or global communications and internet access?

But is the page exactly 33’ of rotation?

Sandy Cheeks is going to need to have a word with you.

You mean we should be spending money to make asteroids hit Texas, right?

To be clearer, the phrase that does that is "DART Mission".

Those are all real problems, I'm Bored, Tired, stressed, and the ground the ugly unmaintained lawn makes my depression so much worse I don't know if I can hang on much longer.
Those things affect me daily, immediately. This stupid potential once in a hundred million years chance we get hit by a rock from space isn't a now problem so stop using Now money on it.

Reply to comment by spaetzelspiff in Moon Time Zone - European Space Agency wants to establish a time zone for the moon with the expectation of more moon activity/coordination by Tinkerer221
But only in some lunar time zones, not all of them. And then we can arbitrarily change which zones do which from year to year to make it more fun.

Just make sure to include daylight savings time to benefit the lunar farmers.

It's the idea that we're sending piles of money into space or something. That money is being paid to the people that work on the program, who then put that money back into the economy.

Fun fact: If you Google NASA DART, the spacecraft will fly into the page, which gets hit and stays crooked.

They also reflect light from Earth and natural sky glow from the atmosphere, back down. This is why LEO satellites are still readily visible through telescopes or long exposure imaging despite being in the Earth's shadow.
This sub crawls with people who literally have never looked through a telescope in their life saying "ThEy ArE iNvIsIbLe BeCaUsE sHaDoW!". It's simply not true. They are most definitely visible. Not necessarily always naked-eye visible, but they don't have to be for swarms of them to be contributing to light pollution levels.

> People here
People here are paid by Elon Musk to astroturf and simp for the commercialization of space.
Billionaires get to exploit a natural resource, and it's spun as if it's some great humanitarian effort for the third world.
I promise the people here using 3rd world internet access as an excuse to justify this don't give a single shit about 3rd world people or their internet access. They are paid to be here to propagandize the commercialization and exploitation of space for the benefit of billionaires.

It's already affected.
Current satellite levels have raised natural background brightness by 10% in dark areas that are normally free of artificial light pollution:
Just wait until all this over-commercialization of space results in 100x the number of satellites, as well as orbiting billboards.

There are always several "large" asteroids passing a few million km from the Earth...

Imagine a cinder block covered in 6 inches of compacted sand. You shoot it, and the bullet dissipates most of its energy hitting the sand. Now imagine a cinder block covered in 6 inches of loose sand just floating around it and barely touching it. You shoot it, and the bullet goes through most of the sand and hits the core of the cinder block, visibly moving it with all the energy.

I still don't understand why those two are different.

The moon should have two clocks.
The first clock fixed to GMT, facilitating coordination with Earth.
The second clock has 354 hours, with AM and PM, so the people on the moon know when to expect sunrise and sunset.
The two clocks should be called Earth time and Lunar time.

You obviously have never been outside an urban area. Nobody will be running fiberoptic cable into the Canadian hinterland. Or back country Africa. That is pure nonsense. It costs thousands for farmers to hook up the last mile. How much to hook up the last 500 miles? All of Canada outside the cities is extremely remote. I have driven much of it.
