SpaceX sent 27 of its Starlink internet satellites toward low Earth orbit from California this evening (April 3). A Falcon 9 rocket carrying the Starlink craft lifted off from Vandenberg Space Force Base today at 9:02 p.m. EDT (6:02 p.m. local California time; 0102 GMT on April 4).

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.

SpaceX has successfully launched the first-ever human spaceflight to orbit Earth over its poles, marking a historic moment in space exploration.
