Expected Impact on Spaceflight:
Cost reduction: By being fully reusable, Starship could dramatically lower the cost of access to space, potentially by orders of magnitude.
Increased access to space: Lower costs could democratize space access, enabling more countries, companies, and even individuals to participate in space activities.
Mars colonization: SpaceX sees Starship as key to establishing a human presence on Mars, with the ability to transport large numbers of people and cargo.
