Well, my middle finger is numb, but I beat 1000 points. I took a straight path upward, and then switched to a horizontal -90° burn, slowly shifting to a -135° burn as I got closer to the ground.

I managed to get my rocket very very slowly rotating ( Unbelievable, the crater is visible from Earth Score: 1712.2 point crash Speed: 15226.2mph Angle: 174.3° Time: 5963 seconds Flips: 0 Max speed: 15226.2mph Max height: 1993862ft Engine used: 21 times Boosters used: 14 times https://ehmorris.com/lander/

Now that's impressive.

1h40m for it though..., that's an extra 1h15m for just 800mph more. With some tweaking of your initial launch angle (get it somewhere between 40-60° rather than 0° which is what I'm assuming yours was, correct me if I'm wrong), plus maybe a second fine-tuning once you reach apolune, I'd guesstimate you could make 25000mph in ~3000 seconds.

The quickest (in terms of time elapsed) crash I've been able to get is 5 seconds. I think 4 may be just about possible, with the right initial conditions.

Nice. I can get 5 reliably, but haven't been able to get 4 at all.

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/

Took it up to 1 million feet, it took another 1.5 million feet to bleed off 4000mph upward acceleration, then turned the pointy end downwards and accelerated.

Tried to get a good landing with as few control actions as possible. For a simple new scoring system, subtract your number of control actions from your landing score: Very nice landing, amazing Score: 90.5 point landing Speed: 2.9mph Angle: 0.2° Time: 18 seconds Flips: 0 Max speed: 53.7mph Max height: 425ft Engine used: 1 times Boosters used: 3 times So, a score of 86.5 in the new system.

I was trying the same and this is super impressive… only 1 main engine fire??? I think this is actually part of the constraints of the real world landing problem.

Yeah, first thing I did was to try to get a feel for when I needed to hit the main engine. Executing a landing with 1 or 2 fires I can do with some regularity. Getting the boosters to 1 or 2 is very hard due to initial conditions, but 3 to 5 is also somewhat doable. All of it coming together for a 90 point landing involved some luck for sure.
