ultra fast spacecraft that could carry humans to Mars in weeks instead of months, and to the nearest star system outside our own (Proxima Centurai) in just about 30 years

= = =
Proxima Centurai = 4.24 light-years away = 24.9 trillion miles
4.24 / 30 = 0.141 times the speed of light.

24.9 trillion miles / 30 years = 0.83 trillion miles / year
= 2274 million miles / day

Curiosity travelled 350 million miles to get to Mars
= = = =

350 million miles / couple of weeks to get to Mars
vs
2274 million miles / day to get to the nearest star

Must be accelerating or decelerating the entire trip to Mars

I think that’s the idea, a small thrust continually applied, would eventually allow very fast speeds in the vacuum of space.
