Build Your Spacecraft.
Launch Your Mission.
Command the Frontier.
DeepSpace is MarsColonia's private space agency operating system. Design real spacecraft with realistic components, launch cinematic missions, and grow a crew that charts humanity's next frontier — from Jezero Pad to α Centauri.
Every mission departs from a real place.
Your agency lives inside MarsColonia — a persistent, domed civilization on the Red Planet. Own land, rent plots, register your company, then take the next step: leave the surface.

From commanders in orbit
"First mission to Proxima b felt like piloting a real ship. The 100-day arc is unreal."
"The workshop is addictive. I keep re-tuning my Δv budget between coffees."
"Invited my crew and we split science ops. Best collaborative tool I've used."
