01 / The experience
A ship worth learning.
A journey worth planning.
Departure 2150 is being built for people who find satisfaction in the flight itself. The instruments. The decisions. The moment a distant destination becomes the view outside your cockpit.
Build.
The planned freight loop gives every crossing a purpose: take a contract, earn your next upgrade, and work toward a ship that opens up new possibilities.
Explore.
Fly above landscapes shaped by real planetary data. Find a new perspective on familiar worlds, from the lunar surface to the reaches of the outer system.
Imagine the next one.
Every vessel gives a different shape to the journey. The C-58 is part of the project's current ship designs; freight progression and upgrades are being built for the first release.
02 / The long haul
Set a course.
Settle in.
Space is vast. A crossing is an operation: departure, acceleration, cruise, braking, and the final approach to a moving destination.
Autonav is central to the vision. Manage the flight, monitor the ship, and develop the confidence to let its systems do their work.
How long is a journey to Jupiter?
Current design targets range from roughly 4–10 hours in a starter ship to around an hour in an advanced vessel. Planetary geometry and final propulsion balancing affect these times.
Can I leave the ship under autonav?
Extended automated flight is part of the intended experience. The extent of unattended operation, arrival assistance, and intervention requirements is still being developed.
Do I need to be an experienced simulator pilot?
Spacecraft mastery is an important part of the game. Flight assistance will support learning; the opening tutorial and assistance defaults are still being designed.
03 / The worlds between
Civilization thins.
The possibilities expand.
Humanity has become an interplanetary industrial civilization. Follow its reach from Earth and Luna to the Jovian system, and look beyond the edge of settlement.

Where the journey begins
Earth & Luna
Orbital infrastructure, lunar facilities, and departures from Port Imbrium.
02
The working Solar System
Mars & the Belt
Long crossings, industrial destinations, and a livelihood built between worlds.
03
The edge of settlement
The Jovian system
A distant commercial anchor, with mining and research destinations planned.
04
The open frontier
Beyond Jupiter
An unsettled outer system. Distance becomes an expedition in its own right.
World direction for the initial release. Facilities and destinations are still in development.
Take the scenic route.
At a different kind of speed.
Planetary landscapes built from NASA and other scientific datasets give exploration a physical foundation. The view is part of the reason to fly.
04 / Inside the simulation
There is a reason
it flies like that.
Follow the questions behind the experience. The mechanics of a moving Solar System. The data beneath a landscape. The engineering assumptions behind the spacecraft.
The laws behind the flight
Extraordinary spacecraft.
Familiar physical laws.
The technology belongs to 2150. The mathematics begins with the universe we know.
01 / Newton
Gravity shapes the flight.
A spacecraft in orbit is continuously falling around a world. Its sideways motion carries it onward as gravity bends its path.
What does this mean for my flight?
Motion and gravity work together. Reaching an orbital altitude is only part of the task; your velocity determines the path that follows.
F is gravitational force; G is the gravitational constant; M and m are the masses; r is their separation. This expression describes point masses or non-overlapping spherical bodies.
02 / Kepler
Every orbit has its rhythm.
In an ideal two-body system, larger orbits take longer to complete. The destination continues its journey while you make yours.
What does this mean for my flight?
An arrival is a meeting with a moving destination. Where it will be when you arrive matters, along with the velocity you bring to the encounter.
T is orbital period; a is the semi-major axis of the relative orbit. This is Kepler's third law in its Newtonian form, for a bound two-body orbit. Additional bodies make real trajectories more complex.
03 / Einstein
Speed changes the calculation.
At significant fractions of light speed, special relativity becomes essential to describing momentum and energy.
What does this mean for my flight?
High-speed travel changes the relationship between speed, momentum, and energy. Accelerating and braking become increasingly demanding as speed approaches the speed of light.
γ is the Lorentz factor; v is speed in the chosen inertial frame; c is the speed of light. At everyday speeds, this factor is very close to one.
