How is this a crash, because of the angle? So, so close to a landing, but still a crash Score: 1.6 point crash Speed: 2.5mph Angle: 12.2° Time: 20 seconds Flips: 0 Max speed: 34.5mph Max height: 221ft Engine used: 20 times Boosters used: 14 times https://ehmorris.com/lander/ This is my best attempt for now: A good landing, keep trying Score: 84.1 point landing Speed: 4.5mph Angle: 0.0° Time: 23 seconds Flips: 0 Max s…

This feels like an achievement: Unbelievable, the crater is visible from Earth Score: 190.2 point crash Speed: 1612.3mph Angle: 98.6° Time: 220 seconds Flips: 0 Max speed: 1612.3mph Max height: 4534ft Engine used: 15 times Boosters used: 129 times https://ehmorris.com/lander/

This is the fastest I've ever seen!

Fun game! After climbing to 1 million feet, it took over 500,000 more to finally reverse direction with the ship pointed down and the engines firing.

Apparently, it's all about feathering the throttle. Very nice! Near-perfect landing, super smooth Score: 96.5 point landing Speed: 1.1mph Angle: 0.7° Time: 45 seconds Flips: 0 Max speed: 43.7mph Max height: 256ft Engine used: 73 times Boosters used: 37 times https://ehmorris.com/lander/ --- I see it took you about seven months from "Initial Commit" to its current state. How did you stay on track all that time?

Yes but you can also compete on using as little throttle/booster as possible! IMO the perfect landing is one where you engage the engine at the exact right moment to touch down at The older commits were part of a previous idea that I abandoned, then a few weeks ago I deleted almost everything and gave it another try. Thanks for playing!

> IMO the perfect landing is one where you engage the engine at the exact right moment to touch down at Would be interesting to see, if optimal control would do just that or use many short bursts.

The amazing thing is all these lunar lander games are harder than actually landing the lunar lander that landed on the moon. That's right it used a computer stabilized system and featured a fully automatic landing program however every lander was actually landed in the semi automatic mode where the pilot controlled the descent but the attitude was still maintained by computer.

And they used an analog computer to integrate and display the landing trajectory in real-time, just like in this game iirc.
