Looks like Mars Horizon is going to try to compete with Kerbal Space Program. Looks like Mars Horizon focuses a lot more on the management of the space program. Will be interesting to see how this game progresses. See it on steam here: https://store.steampowered.com/app/765810/Mars_Horizon/

In Mars Horizon, you take control of a major space agency, leading it from the dawn of the space age through to landing astronauts on Mars. Guide your agency through the space race and write your alternate history of space travel - any of the agencies can be the first to land on The Moon if you make the right choices. Manage the numerous challenges faced then and now:

• Create your base with launch pads, research labs, astronaut training facilities, and much more
• Construct your own custom vehicles from hundreds of combinations
• Launch satellites and crewed spacecraft to explore the Solar System
• Run mission control as you solve the various challenges of turn-based missions to earn scientific advancement and public support
• Explore an extensive tech tree and compete or collaborate with other agencies to plot your roadmap to Mars
• Choose from five unique space agencies, each with their own traits, base, vehicles, and spacecraft
• Create your own custom space agency
