We would never send humans before sending probes to investigate. Photons are efficient, but they're very very small Remember, that's the force from 1 TW actually hitting the sail, so the laser generating that would probably need to be orders of magnitude bigger.ДЇrom F = ma and a 3g acceleration, that comes out to a total weight of 100 kg.ДЎ00 kg for an entire terawatt of power to the sail and basically the entire solar system to accelerate. For 0.1 c and 100 AU, that comes out to 3g of acceleration, which sounds reasonable but actually requires a fuckload of power.ДЄssuming the entire beam hits the sail exactly and the sail is 100% reflective and perpendicular to the beam, the force from the laser is F = P/c, which for a 1 terawatt laser comes out to about 3.3 kN.

With a constant force from the laser and a constant mass spacecraft, the final velocity is v 2 = 2 a s where s is the distance traveled while accelerating. The issue is bigger lasers accelerate you faster, so you leave the range of the laser faster for less total acceleration. Even if you have the last laser stations over twice as far out as Pluto (say, 100 AU), the numbers are still absurd. They could also grab some fresh fruits and vegetables, and whatever artisanal products the floating city locals produced in those years of floating in space (maybe space whiskey? :-)) And if they are advanced enough, they could theoretically stop by, pick up a bunch of your scientists, and take them to Proxima Centauri. Knowing the goal of the mission, would keep the community united toward that goal which would make for a pretty fun ambience!Д®ven if someone else got there before you, it's not a big deal. Because then who cares how long it takes? You're living your life as your city's slowly hurtling through space toward your destination.

It would have gardens, playgrounds, movie theater, and enough humans to keep things interesting. The rock would act as a natural shield, and so on.Д«ut now I think the right way to do this is to build a space dome that's 100% self sustaining. When I was young I imagined humans could get to Jupiter, locate the right size rock (with the right composition), and then basically convert that rock into a 'spaceship'.

You could use gravity assist with our sun, but that requires the ship be able to withstand the intense heat and radiation the sun produces ( ).

With the kind of mass we're talking about (humans, exploration hardware, food, water, etc), ion propulsion and light sails are out of the question.

A powerful shield, because space is vast and full of floating crap that can blow up your vessel (the bigger the vessel, the bigger the attack surface).

Technology to put humans into hibernation safely and reliably.
