Every mission starts as a blueprint.
Every voyage becomes a star.
Pull real hardware onto your hull, launch across eight worlds, and watch fuel burn down, gravity bend your trajectory and comms windows open and close — live, driven by real orbital mechanics, not a slot machine.
Four steps. Real physics the whole way.
No tutorials to sit through — the numbers answer while your finger is still moving.
Blueprint a mission
Name it, pick one of eight worlds, and start from a bare hull with every system drifting around it.
Pull the pieces in
Launch vehicle, fuel, instruments, crew, comms, landing gear, power — drag each toward the hull. Mass, delta-v and risk answer live.
Fly the launch
Fuel burns down in real time, gravity wells bend your trajectory as it passes, and comms windows open and close in front of you.
Watch it become a star
Every flight joins a galaxy you drag through and pinch to zoom. Your stats turn into objects you can turn in your hands.
Everything orbits a single ring
No tab bar, no menus. Swipe the hub to bring a section into view, tap to dive in.
Design Chamber
Real rocket science, not sliders that pretend. The Tsiolkovsky equation runs live under your hands.
System Sphere
Eight worlds orbit one living sphere. Zoom into any of them and read what you'd be getting into before you commit.
Observatory
A launch you watch, not a table you read. Gravity assists bend the stream and comms windows blink in and out.
Timeline Galaxy
No list of past flights. Every voyage becomes a star, and your history is a galaxy you fly through.
Analysis Nexus
Duration, fuel efficiency, comms quality and risk — each a living object floating in space, not a chart.
One ring, no tabs
Five sections hang in orbit around a single hub. Swipe to spin it with real inertia, tap to dive in.
Eight worlds to reach
Earth is where every voyage starts climbing out of. Everywhere else, you have to earn.
Earth
Where every voyage in this app begins by climbing out of the gravity well.
Mercury
Closest to the Sun and hardest to stop at — arriving costs more than leaving did.
Venus
A furnace under permanent cloud. Cheap to reach, brutal to stay.
Moon
Three days out — the only stop here you could reach and return from in a fortnight.
Mars
A thin atmosphere that's just thick enough to make landing interesting.
Asteroid Belt
Far emptier than it looks. Millions of rocks, and almost never one in sight.
Europa
Ice over a saltwater ocean, wrapped in the radiation Jupiter throws at everything nearby.
Titan
Thicker air than Earth and lakes of methane. You could fly there by flapping your arms.
Real orbital mechanics, dressed up as a game you can't put down.
