We have some huge hurdles to solve before we get there. Earth is on the fast track to developing permanent Kessler syndrome. As for just reaching Mars, whoever arrives, the astronauts might be too weak physically to even stand up. There was alot of talk about asteroid mining, but it turns out these asteroids are literally the junkyards of space. Not to imply all asteroids are useless star system leftovers. Its far too soon to be discussing interstellar travel.
Maybe terraforming Venus or a Jovian moon is a better path.
I actually dont know about that moon. Do you know if getting to Venus would take less time?
Jovian = "from Jupiter".
About Venus, IIRC it's ~~cost~~ closer than Mars... But that doesn't mean the travel is shorter 🤷♂️
My earlier comment regards the effects of space on the body. Going from zero gravity to 1G causes muscle degeneration. The people landing are likely to be overwhelmed after a single space traversal.
If you are talking about the zero G in the travel to Jupiter, it can be partially avoided by sending a wheel spaceship. At least until the spaceships can accelerate half of the travel at 1 G and decelerate at 1 G the other half.
