A six-minute E-2 test fire has been completed successfully as the team develops systems for E-2 Vacuum. This test demonstrated the propulsion system's ability to sustain a representative burn duration needed to raise spacecraft to higher energy orbits. The engine operated at nominal conditions, including the first 200 seconds at 102 bar chamber pressure while gimbaling.

The International Space Station stands as one of the greatest examples of international cooperation of our time.
As Europe looks ahead to the next chapter of human spaceflight, we are exploring a range of options to maintain and strengthen our presence in Low Earth Orbit.
Our cooperation with @vast marks an important step in this work, helping us assess future opportunities for European astronauts, research and technology in orbit.

The statue of Prometheus is finally finished.
It was cast in Paris, crossed the Atlantic, and was assembled at Starbase. It took us 100 days to go from nothing to this.
People of the West, we have lived through an era devoid of dreams, devoid of destiny.
But the time has come to reclaim our dream of antiquity.
In a few months, we will start building a new city. It will be the most magnificent city in all of history.
After all, the great dream of the West has always been to rebuild Rome.
Come walk beside us in this endeavor. The world is waiting.
