CAPE CANAVERAL, Fla. (AP) — A lucky break has given an Everett man a seat on a billionaire’s private SpaceX flight this fall.

41-year-old data engineer Chris Sembroski will join flight sponsor Jared Isaacman and two other passengers for three days in orbit during the Inspiration 4 mission.

Sembroski donated and entered the lottery but wasn’t selected in the random drawing earlier this month.

A friend was selected and offered the spot to Sembroski, who worked as a Space Camp counselor in college and volunteered for space advocacy groups.

The SpaceX Dragon capsule, which is currently parked at the International Space Station, will aim for an altitude of 335 miles, which is 75 miles higher than the space station and on the level of the Hubble Telescope.

Isaacman insists they won’t cut any corners as they prepare for launch.

The mission will launch no earlier than mid-September.
