Stellarium && rocketry simulator.

This is a reduced version of our Stellarium and Orbital Simulator software.

It includes the solar system simulator and the Stellarium, as well as a rocketry simulator that covers everything from large classic rockets to next-generation launch vehicles.
What cannot be simulated here are travel trajectories, orbital periods, durations, and similar orbital parameters.

But if you're a night sky enthusiast, especially one who enjoys the experience of nighttime hiking, or if you need a solar system simulator/engine with validity through the year 2100, this is the package for you.
Happy space exploration — and see you out there!
