Cryptocurrency billionaire Chun Wang and his Fram2 crew of private astronauts got a two-for-one deal this week when they watched a SpaceX rocket lift off just hours before their own launch into space.

SpaceX launched a crew of four private astronauts led by a crypto entrepreneur on a mission to orbit Earth over both North and South Poles, a new trajectory that no human has travelled before. The mission will last three to five days, during which the crew will conduct experiments on how spaceflight affects the human body.

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.
