I have always know there are satellites going around the earth, but more often that not now when I casually inspect the night sky I see at least one moving satellite. It’s obvious and no need for any telescope. It feels so different than when I was younger: instead of a sense of wonder at the scale of the universe and nature, it’s a constant reminder of the pervasiveness of humanity’s technology and scope for surveillance.
I don’t really have a specific point from this post other than to express a sorrow for the loss of a night sky from my youth.

Where can I learn about the actual science behind Artemis II?
I haven't really seen any videos or articles that explain how it works, what each component does, or like... what kind of fuel it uses, or what an SRB is or you know like the actual numbers and...
I haven't really seen any videos or articles that explain how it works, what each component does, or like... what kind of fuel it uses, or what an SRB is or you know like the actual numbers and the math and such. I don't know much about rockets but I would like to learn. the official nasa website and youtube channel seem to be... dumbed down and also doesn't actually explain much about Artemis II except for showing images and videos taken from it/of it
