Watch the NASA and SpaceX livestream of the Crew-3 launch scheduled for 9:03 p.m. ET.
The second stage of the rocket separated and continues to push the Dragon spacecraft into space. Crew-3 is officially on their way to the space station.
More than 5 minutes into launch everything is going as planned.
A Falcon 9 rocket launched at 9:03 p.m. from Kennedy Space Center's historic launchpad 39A sending a brand-new Crew Dragon Endurance spacecraft on it's way to the space station with NASA astronauts Raja Chari, Tom Marshburn, Kayla Barron and ESA astronaut Matthias Maurer.
The rocket booster will land on a droneship in the Atlantic Ocean in about 8 minutes.
Falcon 9 fueling is about 80% finished. The launch is an instantaneous window at 9:03 p.m. At this point, any delay will mean a scrub for the day.
There are no issues in the final minutes to launch.
With the help of SpaceX teams all four astronauts are in their spacecraft.
They will be strapped in for launch before the hatch closes. Their custom seats will be rotated for launch position, and final suit leak checks will also be happening at this time. SpaceX will close the spacecraft hatch and then check it is secured and no "foreign object debris" prevents a tight seal.
FOX Weather's Max Gorden is live from Jetty Park where launch viewers are beginning to gather.
SpaceX engineer John Insprucker said the Falcon 9 rocket is powered on and the hatch to Crew Dragon is open awaiting its astronaut crew.
The astronauts are working about 15 minutes ahead of schedule putting the suits on.
Despite the rain and hazy sky down range, Insprucker said it's still expected to move out in time for launch.
SpaceX suit techs are helping the four astronauts into their black-and-white spacesuits. This is happening in the Kennedy Space Center Operations and Checkout Building.
After suit leak checks, the crew will next walk out and say goodbye to their family and friends.
The launch director just provided an update and said there are no issues they are tracking for launch.
SpaceX engineer John Insprucker says the astronauts are about to begin donning their black-and-white spacesuits.
He said while teams are watching the rain and clouds around the Cape they expect the weather to stay west of the launch pad for liftoff.
After a launch readiness review Tuesday, mission managers at NASA and SpaceX felt confident in moving ahead with the Crew-3 launch Wednesday at 9:03 p.m. The launch date has been delayed several times due to weather and a minor medical issue with one of the astronauts.
SpaceX is scheduled to launch four astronauts as part of the Crew-3 mission to the International Space Station on Wednesday at 9:03 p.m. ET.
Take a look at what needs to happen before lift off.
