A NASA official said that “within a few years” scientists will unveil a prototype for a starship that can take humans between worlds. The new project, called the 100-Year Starship, is currently joint funded by NASA and DARPA. So far, NASA has contributed $100,000 and DARPA has given $1 million to the project.
Yeah, funding the research of new types of propulsion with only about $ 1.1 mil. Just consider that the cost of an F-35 Lightning is about $ 100 mil. (or in other words 100 times as much), then you understand that they are not serious about this
