Establish observatories, deploy telescopes, and grow your infrastructure to reveal new targets and opportunities and then aim upwards and put your flying skills to the test. 9.8 is a 2D space-agency simulator where a fully physics-driven universe (N-body orbits, atmospheres, heat management, hydrodynamics) makes every small step earned. Build your program from first hops to interplanetary operations through a uniquely designed local star-system cluster. In 9.8 you will: Design and fly rockets under simulation-grade constraints: mass, fuel, TWR, heat, staging, aerodynamics.

Run your space program : plan missions, manage resources, and unlock new technologies. Explore the Solara system by building infrastructure and discovering all of the secrets that the cosmos hides.
