Space Shuttle & Satelites

1. The Shuttle, The Booster-Rockets, the Fuel Tank and the Satelites have to be researched.
Satelites may used for finding new resources, weather forecast, or communication.
2. The Shuttle, The Booster-Rockets, the Fuel Tank and the Satelites have to be built seperately in different Hangars.
3. The seperately built Shuttle, Booster-Rockets, Fuel Tank and the Satelites have to be put together to one Ready for Launch-Shuttle in another Hangar.
4. The now completed Shuttle is taken to the Launch-Site, the Fuel Tank is filled with Fuel. And than finally Lift off.

I think this is a fantastic addition, and it makes sense because the shuttle is Hydrogen/Oxygen powered just like the existing in-game rockets. Also, a Shuttle can potentially carry both crew and cargo, making it a logical upgrade to the existing in-game rockets that can only carry one or the other.
Here are some potential additional steps (to make the shuttle reusable as in real life):
5. Shuttle lands on your island. Dedicated runway facility near the launch site, needs to be hauled back to the rocket assembly building for re-integration.
6. Shuttle boosters land in the water (random position on the map) and need to be recovered by your ship. Haul back to the manufacturing facility for refurbishing and re-integration.
