All of the human spaceflights that preceded the Fram2 mission have orbited the Earth from east to west. This flight, aboard a SpaceX Crew Dragon spacecraft, is the first to follow a 90-degree inclination.

Elon Musk's SpaceX on Monday launched a crew of four private astronauts led by a crypto entrepreneur on a mission to orbit Earth from pole to pole, a novel trajectory in which no humans have traveled before.

The four-person crew, led by cryptocurrency billionaire Chun Wang, will spend three to five days on a rare flight path around Earth’s poles.
