    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
