Science Friction
12 | Artemis Explained: What a ride

The reason is because I managed to find the data for the Apollo astronauts as they did this kind of experiment with the clocks on board.

Science Friction

So in Apollo 12, there was a gain of 560 microseconds, and Apollo 13 gained 326 microseconds.

Science Friction
12 | Artemis Explained: What a ride

I'm going to say I'm going to make an educated guess and say that the Artemis astronauts would be closer to Apollo 12 because that was also a 10-day mission.

Science Friction
12 | Artemis Explained: What a ride

Yes, and the reason for that is because of general and special relativity.

Science Friction
12 | Artemis Explained: What a ride

I really did enjoy that as well.

Watching the moon as it's doing its thing has been very different the last few days.

Science Friction

Earth is in the middle.

Science Friction

Let's say that we've got a picture, the sun, the moon and the earth in your mind.

Science Friction
12 | Artemis Explained: What a ride

We're standing on some portion of the earth and we can see the sun because it is daylight and that is what happens.

Science Friction
12 | Artemis Explained: What a ride

However, we can also see the moon from where we are.

Science Friction
12 | Artemis Explained: What a ride

Now, when you can see the moon during the daytime, the sun is also hitting the moon at the same time as it's hitting the Earth.

Science Friction
12 | Artemis Explained: What a ride

So when those two things line up, which happens quite a bit, you can see the moon during the daytime.

Science Friction
12 | Artemis Explained: What a ride

Yeah, another good question, and something that you don't really think about as well.

Science Friction

So the space station, which is the biggest orbital satellite in space, is about the size of a soccer pitch.

Science Friction
12 | Artemis Explained: What a ride

Now, that's huge, right?

Science Friction
12 | Artemis Explained: What a ride

That's really, really big.

Science Friction
12 | Artemis Explained: What a ride

But it's not big enough to see unless the two spacecraft were quite close together.

Science Friction
12 | Artemis Explained: What a ride

And in this case, we know that the ISS was quite far away from Orion when it went up.

Science Friction
12 | Artemis Explained: What a ride

It's also worth remembering that Earth is really, really big.

Science Friction

So while there's plenty of space objects up there, over 10,000 Starlink satellites alone at this point, the size of Earth is just so big that it's hard to see these things in orbit.
