- TL;DR Summary
- What am I doing wrong?

My simulator is trying to mimick the actual conditions of the Apollo landing. I have entered in numbers for my runge kutta simulator for LEM mass, dry mass, fuel, thrust of the rockets, fuel burn rate per second etc etc. But I am not able to land, only very close to landing. I copied the conditions from this source:

https://blog.adacore.com/make-with-ada-the-eagle-has-landed

So the LEM starts off at 15 km altitude (50,000 ft) at 1.6km/s speed. But I only seem to barely have enough delta V from the onboard DPS fuel. What am I doing wrong?

2nd failed attempt

1st failed attempt assuming 100km orbit

Does anyone know the ground distance to Tranquility Base before the Eagle started de-orbiting from it's 15km altitude?

Important note: This simulator has time acceleration so don't get confused why it sometimes fast forwards while deorbiting.
