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.

Mikkelsen, the first Norwegian bound for space, has flown over the poles before, but at a much lower altitude. She was part of the 2019 record-breaking mission that circumnavigated the world via the poles in a Gulfstream jet to celebrate the 50th anniversary of Neil Armstrong and Buzz Aldrin’s moon landing.
