No, Elon Musk is not going
Four people are set to launch to space Wednesday night aboard a SpaceX capsule, and none of them are professional astronauts. Jared Isaacman, a billionaire entrepreneur and philanthropist, booked the Crew Dragon capsule last year and picked three normal folks to ride with him. It will be the first completely private mission to orbit.
They're actually going to space, and not just barely:
This mission’s destination is about 80 miles higher than the ISS. In orbit, they’ll view Earth through two windows and a new glass dome that was added to the top of the capsule, where Crew Dragon’s ISS docking door was. The crew will reenter the atmosphere after three days, depending on the weather around Florida, and splash down in the Atlantic ocean. SpaceX recovery teams will likely meet up with the capsule, hoist it onto a ship, extract the crew, and bring them ashore.
