Keplerian Space Discovery

Disappointed by the failure of KSP2, I've been looking for an alternative and have been following this since last year, and it's finally been released. Since it's still in early access, there are noticeable inconveniences and bugs, but the developer are diligently addressing them, so I believe it will stabilize eventually, catch up to KSP, and ultimately surpass it. Note: For now, I think it might be a bit difficult without some prior knowledge of KSP and similar games. ---(additional information at 20th Mar 2026) For Kerbal Space Program users The gameplay feels like vanilla KSP + mechjeb2. Of course, manual control is possible if you turn off AutoPilot. ---(additional information at 21st Mar 2026) Frankly speaking, the Maneuver Planner is currently difficult to use and has some issues.

The game is really good. I’ve enjoyed playing it, and now that it’s in early access, I’m sure it’s only going to get better. I played the demo for a few weeks and had a lot of fun with it. I haven’t put too many hours into the full release yet, but I’m definitely going to keep playing more and more. Good luck with the development!

So far, I am finding myself playing this more and more ... scratches the space rocket-itch ...

Great game, chill and realistic at the same time.

A great start, the closest to a KSP successor as i've seen yet, look forward to things added over.

Ich bin begeistert! Nach dem Desaster von Kerbal Space Program 2 nun endlich die Weiterentwicklung! Ich hatte auf der Gamescom 2026 die Möglichlkeit mich mit den Entwicklern auszutauschen. - das war perfekt. - es ist zwar EarlyEarlyEarly Zugang, sozusagend gibt es keine Kerbals, aber im Grundegenommen ist es wie Kerbal Space Programm und durch das Gespräch mit den Entwicklern, der mir die Roadmap erklärte, bin ich vollendsüberzeugt! Danke für die Möglichkeit die Bedenken im direkten Austausch zu klären. :-)
