"Lift off!"
A newly manufactured Falcon 9 rocket carrying the spacecraft codenamed "Dragon-Gravity" soared into the sky from Cape Canaveral. It was an unmanned launch.
Nearly a year ago, Musk proposed the "flexible gravity solution," and after a lengthy development process, Lockheed and SpaceX made it a reality.
Actually, the most fundamental and important cable technology was easy to solve. Once the Dragon spacecraft, weighing less than 20 tons, splits, each end has a mass of less than 10 tons. The centrifugal force generated by the rotation was quite manageable.
It took only three months to solve the FGD section, but the spacecraft's design needed major changes, which took over half a year.
The original interior design of the Dragon spaceship didn't consider gravity issues. To provide astronauts with the proper direction of gravity, a re-docking had to be performed in space.
