Do you want some porkchop?
Navigating throught space
You need to solve Lambert’s problem to find the orbit between two points in space.
Input:
- Gravity parameter
- Position at origin
- Position at arrival
- Time of flight
Solution:
- Velocity at origin
- Velocity at arrival

Lamberthub is a library containing a set of algorithms for solving Lambert’s problem.
from lamberthub import authorYYYY
v1, v2 = authorYYYY(
mu, r1, r2, tof, M=0, prograde=True, low_path=True, # Type of solution
maxiter=35, atol=1e-5, rtol=1e-7, full_output=False # Iteration config
)The launch and arrival velocities are used to compute the impulses of the maneuver.

Quick way of visualizing the solution space:
The more energy, the more fuel you need
The more fuel, the less payload you can carry
Low energy trajectories are desired
Fast arrival times may be desired too
