The SpaceX rocket and spacecraft technology company scrubbed its launch of 27 satellites Tuesday from California.

Fram2 will send four people from four different nations to low Earth orbit for three to five days. Those crewmembers — all of them spaceflight rookies — are mission commander Chun Wang of Malta, vehicle commander Jannicke Mikkelsen of Norway, pilot Rabea Rogge of Germany, and Australian Eric Phillips, Fram2's medical officer and mission specialist.

The international all-civilian Fram2 crew is the first in space history to fly to orbit with no licensed pilot or trained astronaut on board.

The crew will observe Earth's polar regions 430 kilometers above the surface, allowing the Crew Dragon Resilience to travel from the North to South Pole under an hour.

SpaceX is gearing up to launch Fram2, the first crewed mission to orbit Earth's poles, on Monday night from the Kennedy Space Center in Florida. The historic mission will carry four civilians from four countries.

During the first quarter of the year, 27 orbital rockets took flight from Florida's Space Coast. That equates to a cadence of 108 launches by year's end — a record-breaking pace that would erase last year's record of 93 annual liftoffs.

SpaceX's Starship megarocket, the world's most powerful rocket, is officially on NASA's list for future launches.

The U.S. Federal Aviation Administration on Monday said it closed out a review into SpaceX's explosive Starship test flight in January, while another investigation into the rocket's subsequent testing explosion in March remains open.
