Perhaps the biggest project being undertaken by SpaceX at the moment is their Starship. Yes, it is exactly what you think it is. They have already built most of it and are currently developing launch sites for it. This ship, unlike any of the Falcon Rockets, is going to be used for human travel into space. It is the very first launch vehicle ever made for human travel to be completely reusable. It is the tallest, most powerful launch vehicle ever made. The Starship works in two stages, which consist of the Super Heavy booster stage then the Starship’s second stage comes into play…also referred to as the spacecraft itself. This spacecraft is going to have four things inside: the cargo, crew, propellant tanker, and lunar lander.
The Starship launch will be able to deliver 220,000 pounds of force as it enters into Low Earth Orbit. The cool part is that once in orbit, Starship tankers can refuel the spacecraft to transport into higher orbits or other destinations beyond LOE. This spacecraft will also be able to enter the atmosphere of most planets. It can then use its engines to land properly or it can be left in space. They’ve been working on it since 2005, so it is very likely Tom Mueller had been behind a lot of it. He was especially part of the Raptor Engines development. Several engineers are also involved in making it work along with NASA and the FAA. Yet there are still questions surrounding the Starship, particularly for exploration. Elon Musk might have been planning to do this, but he never was involved in the development process itself.
