OK, so how do you know the parameters for suicide burn?
"just"You just need to use Newton's equations for linear motion, and solve for distance, using your known parameter's. In Space Engineer's, it's fairly easy, since you know your maximum velocity (110 m/s), your ship's mass (on the HUD), your ship's thrust (480kN), planetary gravity (Earth = 9.81 m/s2). That’ll tell you your minimum braking distance.
Kerbal Space Program is even easier in the base game, no MechJeb mod (an autopilot mod) required. Just create a maneuver node right before your impact point, one where the eccentricity is as close to one as possible, and the apoapsis touches the maneuver node, and you’re good.
Close to one, not equal to one. An orbit with an eccentricity of 0.999 is about as close to vertical as an orbit can get."just"
I'm not a rocket scientist. The KSP nodes I did. To have an indication when to initiate break. Eccentricity of one is a parabola - how does it all make a suicide burn?
Do you know a good sattellite mod? It's years now but I had one that mapped the surface and features. It taught me why a polar orbit is useful. It kinda got discontinued and the idea was so good it got basic feature in KSP but it is crude and janky imo. I want higher resolution - especially now that you taught me the secret to the perfect landing burn.Practical Rockets

Now with More Kerbals!
Sometimes, life gives you just enough play time to build and launch a single rocket...
At any rate, having had time to reflect on what I wanted to do, I elected for the general construction node. I would be running those two nearby high altitude observation missions, so I should get enough science to unlock the other node as well. Those launch clamps in particular are too dang useful to ignore for long. An unsteady rocket on the launch pad could cost hundreds of meters of delta-V when you're aiming for an equatorial orbit!
Next, I accepted the mission which would send Jeb over the water.
Over the years, I’ve developed several templates for “low tech” launches. Adding a utility bay and heat shield to the single-seat capsule allows me to recover their contents while keeping the reentry vehicle stable during descent. Frequently, it’s the capsule and the bay's contents that’s the most expensive part of a rocket, frequently accounting for at least half the cost, and recovering it helps keep costs down.
In this case, the only payload is the science container. But you can cram a lot of stuff into that tiny space, like solar panels, antenna, and other science instruments.
The rocket itself is a two stage one: the lower a solid fuel rocket to get it above the densest air, and the upper to push the entire thing over the observation site. Two material science bays will get the lower and upper atmospheric science that's available. Sadly, there's no way to recover them at this time, so I'll just have to absorb the cost.
After everything was set up to my liking, all that remained was to launch the rocket.
Just raw footage of the mission, no time add text commentary...

Once I'd unlocked the Flight Control tech node, it was time to see what new mission was available...
This mission should be possible to do using a plane, but I might be able fulfil it during the second observational mission.
Next up... completing the observation missions, and hopefully getting a rocket into orbit. After that, it's time to start rebuilding my jump ship in Space Engineers!
The only one I can think of is SCANsat, which hadn’t been updated in years, near as I can tell…Do you know a good sattellite mod? It's years now but I had one that mapped the surface and features.
