On Tuesday, SpaceX launched a historic mission to the International Space Station, sending four astronauts from three countries into orbit.

The Crew-6 mission was launched at 5:49 a.m. EDT from NASA’s Kennedy Space Center in Florida, carrying NASA astronauts Shane Kimbrough and Megan McArthur, Roscosmos cosmonaut Oleg Novitskiy, and United Arab Emirates astronaut Hazza Al Mansouri.

The mission was the first time astronauts from the United States, Russia, and the United Arab Emirates have flown together in space.

The launch was attended by hundreds of spectators at Space View Park in Titusville, Florida, who cheered the liftoff and watched the Falcon 9 rocket soar into space.

The mission was SpaceX’s 101st successful rocket landing, and the second attempt for the Crew-6 mission. The first attempt was aborted due to unfavorable weather conditions.

The Crew-6 mission is part of NASA’s Commercial Crew Program, which is designed to make space travel more accessible to the public.

NASA is providing coverage of the mission on its website, with updates on the astronauts’ progress and mission highlights.

The Crew-6 mission is expected to arrive at the International Space Station on Thursday, where the astronauts will stay for six months.
