Trajectories to the Moon

Calculating trajectories for spacecraft to the Moon is not easy. Without the required velocity the Moon is not reached, and the return to Earth is a disaster. Even with the right velocity, making it back to Earth safely is not a given.

The launch point rotates once every 24 hours and the Moon moves around the Earth in 27 days. We need to shoot from a rotating launch point to a rapidly moving target.

Luckily, Nasa does it better than me.

Video | 1 years ago

The Final Experiment: Sun over flat Earth

Video | 2 years ago

There is no way that a sun, relatively close to the 'flat Earth' can create the light patterns that are revealed by looking up day hours/night hours for every city on the Earth. There really is no need to go through the efforts and expense of travelling to ...

How the Gleason map was made.

Video | 3 years ago

L.E.O. and Banjo stupid?

Video | 4 years ago

Both Level Earth Observer as Banjo published a vid claiming that the sun lights up more than half the Earth, so the Earth cannot be a sphere. Here are the two masterpieces: LEO's: https://www.youtube.com/watch?v=PKkntWfacF4 Banjo's: https://www.youtube.com/...

Sun over Spitsbergen : the flat Earth Sun orbit!

Video | 4 years ago

I already made a similar film about the sun above McMurdo staion in Antarctica. Flat Earthers waved this away with their silly nonsense of "there is no 24-hour sun in Antarctica". Well, this is about a place above the Arctic circle, so waving that away is g...
