Yes, it IS rocket science !

I had to google the above!

Are you mocking me

I've asked you before not to steal my lines.

you don't think Russia and China would have presented photos ridiculing the US?

You don't think the radio, and video transmissions were able to be DF'ed - with the source of the transmissions, confirming the directions of the locations precisely?

Probably, I didn't give it much thought.

wasn't convinced by this though

I didn’t think intelligent people denied moon landings. Far age has an easier ride than I thought

but what about TV detector vans.

DF'ing TV's did work, back in the day, and they really were able, to tell which channel you were watching - by DF'ing the line time base, and comparing, but there were very few vans, and many were dummies. Modern digital, flat screen TV's are much more difficult.

Tracking and DF'ing from satellite and space capsules, is much more precise, have you ever needed to align a satellite TV dish? Transmission and reception, from the capsules, and moon lander, involved large several dishes being used, scattered around the earth, directed at them, so no doubt where they were at the time. Jodrell Bank, played its part in that.

so russia who achieved every first in the space race didnt put a single person on the moon i wonder why that is
The video clips of buzz aldrin speaking to kids questioning him in later life are quite interesting basically denying it happened

something I've never really thought about.

what has Justin passing been saying now ?

slimshady is just upset that nobody believed his Reform can make torture legal, if we leave the ECHR boll@x.

 

[noseall]

I have never known anyone so desperate to convince people how clever and rich he is. So sad!

We call those people c**ts, oop our way.

Hardly a moon landing. A big 70’s con, surprised there hasn’t been a public inquiry into it as it involved the beeb. The difference was that scientists knew that detector vans were fake, and the moon landings real.

something I've never really thought about.

The moon was an order of magnitude harder than all the orbital stuff. The Russian rocket, the N1, was a bad design and kept exploding.

You need really, really big rockets to lift 45 tons into lunar orbit. So big they're pointless for nearly everything else.

When it became obvious the US missions were only doing photos and science there was no real need to repeat it or develop their own super heavy rocket.

They couldn't feed the people, let alone continue a race to the moon; and no such thing happened with Aldrin.

Watched the news a couple of days ago, with great interest in the SpaceX rocket launch/programme.......
So how does the biggest, heaviest rocket ever made, after being launched and flying halfway around the world, manage to ' gently land', arse end first into the ocean ? I mean, this thing is 400 ft long, falling to earth at god knows how many hundred miles an hour, presumably head first, but somehow can stop and do a 180, then ever so gently and controlled ' land' in reverse ?I
I don't get it, but it's pretty awesome

Practice.

SpaceX started doing 'propulsive' landings with part of their rockets after they'd finished boosting their payloads.

They failed, a lot, for a long time. But each time they got a bit closer. Then they finally managed to get the formulas right and they've now landed almost 500 of times.*

The Superheavy and SpaceShip are much bigger, and SpaceShip is moving much faster, but their practice with the falcon 9 has given them the basics and shown it is possible.

Is there any reason, in theor,y why a rocket coming down shouldn't be as stable as a rocket going up. Instinctively, it feels like it won't be. But I can't think what the scientific explanation would be.
