Sunbeams

[Peter]

Hi Charles,

It is early in the morning, here in Germany and I am seeing  the sun with  its belles brilliance.
I do not know why this not happens  in Wales. I guess  there are too many Ufos and the sun is not visible.

Here is  an aternative.

A simple program for training astronauts in the art of putting a spaceship into a close stable orbit.

The only controls available are Acceleration (up arrow key) and deceleration (down arrow key), so timing and duration are critical for setting up a stable orbit.

Hi Charles,

Super program.
I landed three times on the red Planet and was not attacked by the Alien.
This program is really easy to understand, we should have more of it.

Thank you.

There is something not quite right about my orbital / gravitation algorithm. Essentially gravitational force is proportional to 1/distance^2. This force has to be resolved into x and y force, then applied to the x and y speed.

Anyway it could make space travel more interesting, especially through the asteroid belt
