Humanity needs to simplify the technology and products for our civilization but make them fully scalable and self-replicating. The technologies that we pick to scale need to be ones that we can increase to a thousand times our current levels with manageable pollution and side-effects at those scales. We will soon have billions or trillions ... Read more
Earth orbiting satellites have the speed to counter the Earth’s gravity. The mean orbital velocity needed to maintain a stable low Earth orbit is about 7.8 km/s (4.8 mi/s), which translates to 28,000 km/h (17,000 mph). However, this depends on the exact altitude of the orbit. A statite, or static satellite, would use a solar ... Read more
The super heavy booster can be used more frequently than the ship, as it returns in about ~6 minutes and can theoretically be ready for reflght in an hour. The ship needs to complete at least one orbit, but often several to have the ground track line back up with the launch site, so reuse ... Read more
