Artemis 2 Going back to the moon.

C'mon Dave there's no need for that, science is based on opposing theories. Are you saying you are a special one who knows the real truth and anyone who disagrees with you is a clueless fucktard lol.

No, but I am saying those desperate to believe it is not real, faked, we live under a dome etc, (e.g. batshit crazy stuff) should keep to their own little worlds and not pollute decent discussion on actual scientific discussion with mental ideas that have been conclusively disproved.

I have to admit this 55 year old man was choked up watching the launch, and I’m not at all embarrassed at this, memories of a young lad in the 1970s getting his first science book for a Christmas present and looking at photographs of astronauts and huge rockets in wonder, watching the first space shuttle launch from an assembly hall at junior school….

I had this one. Was fascinated by the space stuff. Knowledge was precious when it was hard to access pre Internet.

Heard multiple times today that it's the first time we've left earth orbit since 1972. Given that they're going to the moon and the moon by definition is is earth orbit how can this be a thing?

They may have said Low Earth Orbit? Up to around 1000 miles up where the ISS and most satellites hang out. It’s the first time we’ve been above LEO for decades.

I remember reading once years ago that the bog on the space shuttle was always kaput. Apparently it cost millions to develop. The Russians however had no bother with the one on the Mir space station as it was basic mechanics with a hand cranked vacuum pump. No idea if true but sounds about right. When I went to Disney Paris once they had a space exhibition with a soyuz capsule. The heat shielding was oak planks whereas the shuttle had fancy ceramic tiles which kept dropping off. Another similar tale was that NASA spent money developing a space pen which worked in zero gravity. The russians apparently used pencils. Sometimes the simplest solution is by far the best.

And this is why you shouldn't listen to the "hur hur" idiots that sit in the corner and ridicule what smart people do.

The pencil nibs would break off, and float into the electrics and cause a huge risk of shorting something out. Don't think that's a cracking idea in space..... and exactly why the yanks spent a fortune inventing something to remove that risk.

I had a huge grin on my face when that image first appeared on my socials feed, I couldn’t tell you how much I have spent looking at it, looking little stuff like the Aurora green glow on top right and bottom left.

First time anyone has ever laid eyes on this view of the moon, love stuff like this....truly groundbreaking

Managed to have a search and found the book I was thinking of…

Exploring Space (St Michaels)

I think that one belonged to my brother, he also had one called “Space Wars, worlds and weapons” and I got a science and natural world one and encyclopaedia of dinosaurs all published by St Michaels (publishing arm of Marks and Spencer I think)

Thread with the book chat takes me back. I had two precious books. Dinosaurs and space. Can't for the life of me remember who published them

Isn't the radiation a bigger problem on that far, far longer journey? How big a rocket for the amount of fuel needed?
Click to expand...
I am not suggesting a rocket, i am saying something the size of the international Space Station, maybe even bigger, radiation is a problem your right, but gravity is the bigger issue. for a trip that far, you need to find a way to make gravity, so you need your ship to be faster, than what we currently have, and the other problems mentioned, it's just making the right discovery's with technology at this point.

Getting to Mars is reasonably straightforward (as much as these things can be). It's getting back that is the hard bit.

Absolutely this - unless they find a way to synthesise fuel on Mars or persuade people to make it a one way trip.

This is exactly why SpaceX have built StarShip around burning Methane. It can be synthesised from CO2 and hydrogen using the Sabatier reaction. Both of those are available on Mars. (it has a useful by product called water)

Galileo Galilei was condemned and placed under house arrest for defending heliocentrism (the theory that the Earth revolves around the Sun) and for refuting the Bible as the final authority on scientific matters. Was he a fucktard aswell lol
