Nebra I (with Nereid 1 submarine)

Nebra I is a rocket designed to carry one (1) submarine, Nereid I, to the innermost moon of Tydos. The rocket will use 3 of its four main stages getting into orbit, then the 4th stage is your best friend for getting to Nebra.

When you attempt to land on Nebra, get inside the atmosphere and keep your speed at 1,100m/s or less. Then, cancel out all of your lateral velocity and use the plasma engines to control your descent speed, keeping your descent angle vertical. Keep your speed below 12m/s when entering the water, then open the cargo bay doors, deploy the submarine, and then switch to the submarine's controls. Slider 1 controls Nereid's propellers, the control sticks do the rest, and AG7 operates the navigation lights.
