    When your ship is going to the Sun, it has to cancel out nearly all of the orbital motion it inherited from Earth. In order to have the ship drop straight down towards the Sun on a one-way collision course, the ship would have to leave Earth’s sphere of influence at a relative velocity of 30 km/s.

    But remember, Earth’s gravity will try to pull the ship along with it, so in reality you’d have to depart from Earth at a relative velocity of about 31.6 km/s (70,700 mph). That’s nearly twice as fast as the ship would have to go in order to escape from the Sun.

    The parker solar probe cost was about 1.5 billions. A fully manned one way Mars mission would cost about 20 billions going by the cheaper estimate.

    The same one way mission going to the sun would be 10k times more expensive.

    About 2 hundred trillions USD

    By 2022, total earth GDP was about 100 trillions.

    Yeah it’s not happening anytime soon

      Couldn’t you just go for a slow, spiralling course instead of the direct route? Much less correction needed from Earth’s course, just a constant deceleration relative to the orbit path.

        I mean at this point it’s cheaper to focus on building the future instead of whatever the original question proposal was

      Ok, listen tough guy, you make that a two or even three way trip or whatever you need, do the math while the rest of us catch the rich and plunder their physical vaults full of gold coins which we will use to buy the rocket, and then we meet up again to discuss how to shove 'em up there kay

          I’ve read Donald Duck comics back when I was a kid so I would say that my understanding of how the rich operate is pretty much perfect representation of reality, thank you.

              To be completely honest, I wouldn’t be surprised if Musk or Bezos had a pool of coins somewhere in their homes “just to see if it works” or “to have this experience”, it’s the least wasteful thing I would expect of them.
