BREAKING: NASA astronauts blast off into space on a SpaceX rocket, heralding a new era in human spaceflight. For updates, go here.

Earlier story:

It’s launch day.

Following a postponement, Saturday will now mark the first time in nearly 10 years that American astronauts will launch into space from U.S. soil after Wednesday’s launch was postponed due to concerns over weather conditions. The mission is scheduled to send NASA astronauts Bob Behnken and Doug Hurley to space aboard the Crew Dragon capsule, designed by Tesla founder Elon Musk’s SpaceX company. The rescheduled launch is taking place at the Kennedy Space Center in Florida at 12:22 p.m. PT (3:22 p.m. ET) on Saturday, May 30.

If weather or other factors prevent the launch from happening again on Saturday as it is currently planned, SpaceX and NASA can try again on Sunday with a 60 percent chance of being able to begin the mission on those days.

The spacecraft is intended to dock with the International Space Station. As CNET reports, the Demo-2 mission is “part of NASA’s Commercial Crew Program, which involves two commercial spaceflight companies, SpaceX and Boeing, building and launching crew capsules designed to ferry astronauts to and from the ISS.”

If all goes to plan, the May 30 event will mark the first time SpaceX has launched humans into space. In honor of the historic occasion, TV, streaming services and other outlets are offering several ways to watch the space launch. Here are key details:
