About This Game

M = E - e * sin(E)

Keplerian Space Discovery is a game in which the objective is to explore celestial bodies in the solar system, such as the Moon and Mars, by launching rockets of your own design.
The motion of each celestial body is precisely reproduced by the Keplerian equations.
You will feel both the excitement of touching the unknown of the universe and the relaxation of its beauty.

Build your own rocket

Build your own rocket by combining parts such as an engine, fuel tank, and fairing.
You can also build your own satellite by combining solar panels and reaction wheels.
The better you build it, the better it will fly.

Over the Kármán line

Once the rocket is assembled, it is time to launch it.
The first goal is to get the rocket over the Kerman Line (100 km altitude) and into Earth orbit.
Altitude and horizontal velocity are important, and you also need to pay attention to the remaining fuel.
Sounds difficult? Don't worry. Just specify the target orbital altitude and inclination, and the computer will take care of the rest.

Marvel at the view from orbit

Once you have successfully placed it in orbit around the earth, take a look below. You will marvel at the beauty of the Earth.
You may even find your city.
Don't worry, even if you run out of fuel, you will not fall.

Doing Business in Space

Accept a contract to launch a satellite and put it into the designated orbit.
It is the customer's precious cargo, so be careful not to damage it.
You need to be as delicate as carrying a kitten.

Meet the Anomalies

When traveling in space, we sometimes encounter strange objects or phenomena.
Perhaps they are from outside our solar system.
There are things we still do not know.

Fly Me to the Moon

First, let's go to the moon, the moon.
It is a big step for us.
No rabbits.
