- Major Update #2 Preview - 24 July 2026
Greetings Space Explorers!It's been a while since our last update, so we would like to tell you about the current and future plans for Solar Expanse development. Let's have a look at what's coming in Major Update #2 in just a few weeks!Space StationsWhy space stations? They answer some of the game's current issues and make the gameplay smoother by keeping crews alive in orbits, making productions way more efficient (especially electronics!), and reducing the fuel costs of orbital launch! Stations will be modular - each one will consist of a base operational module, which can be extended by 10 more of your choice. Models will be visible in orbits!This was also the most requested feature from our roadmap, so we made sure that it will add more flow and impact to the gameplay.Drag and drop missions for free orbital transfersTired of clicking through the entire mission planning for some orbi…
