Flight dynamics / Introductory note
Your destination is moving, too.
An interplanetary flight is a meeting between moving objects. The destination keeps going while you make the crossing.
A course toward an arrival
Pointing at where a planet is now is only the beginning of the problem. During the flight, the planet continues along its orbit. An arrival plan has to account for where it will be when the spacecraft reaches it.
This is one of the principles behind Departure 2150’s moving Solar System. The flight takes place within a physical system that continues to evolve around the pilot.
Getting there includes slowing down
Closing the distance is only one part of a rendezvous. The spacecraft also needs an appropriate velocity relative to its destination. A successful arrival joins position and motion together.
For a pilot, that makes braking and approach part of the journey from the beginning. The view of the destination growing in the window is accompanied by a more important question: what is our motion relative to it?
Automation is part of operating the ship
Navigation assistance belongs within this experience. The intended role of autonav is to help execute a flight through the simulation’s controls and spacecraft capabilities. Understanding what the system is trying to do remains part of learning the ship.
The exact arrival assistance and unattended-flight behavior for the first release are still being developed.
Watch the arrival
In the gameplay trailer, the destination is more than a point of light. The approach becomes a practical problem of position, motion, and timing. Later flight notes can explore reference frames and trajectories in greater depth as those demonstrations are documented.
