5 ways to watch SpaceX's historic first rocket launch of NASA astronauts live online
  • SpaceX is about to launch its highest-stakes mission since Elon Musk founded the company in 2002: Its first launch of people.
  • NASA is working with the company to launch the mission, called Demo-2, which will fly the astronauts Bob Behnken and Doug Hurley inside a Crew Dragon spaceship.
  • Liftoff is scheduled for 3:22 p.m. ET on Saturday, though poor weather and other factors could delay the mission to Sunday at 3 p.m. ET.
  • SpaceX, NASA, Neil deGrasse Tyson, National Geographic and ABC News, and others will be broadcasting live video coverage of the mission, most of which you can watch online here.

CAPE CANAVERAL — On Saturday at 3:22 p.m. ET, SpaceX plans to rocket its first people into orbit since Elon Musk founded the company 18 years ago.

If successful, the historic mission would also resurrect NASA's ability to launch its astronauts to the International Space Station. The US space agency flew its last space shuttle in July 2011 and has relied on Russia ever since to get to and from the orbiting laboratory.

NASA picked the astronauts Bob Behnken and Doug Hurley, each of whom has two space-shuttle missions under his belt, to pilot SpaceX's experimental test flight, which is called Demo-2.

"We have this moment in time where we can unite people again," Jim Bridenstine, NASA's administrator, said during a press briefing before launch. "The whole world is going to be watching this."

Demo-2 is launching from Launch Complex 39A at Kennedy Space Center in Cape Canaveral, Florida.

The company pushed for a launch on Wednesday, May 27, going so far as to fuel the Falcon 9 rocket with two astronauts inside the Crew Dragon spaceship on top. However, problematic clouds and the threat of lightning forced SpaceX and NASA to scrub the attempt and delay the launch.

The rocket and spaceship carrying Behnken and Hurley has just a second or so to lift off and get on the right path to meet the ISS and stay there for up to 110 days before returning home. So if there's another delay in the launch on Saturday, SpaceX and NASA can try again at 3:22 p.m. ET on Sunday. The US Air Force 45th Space Wing's weather officers on Wednesday said there's a 50% chance of liftoff for Saturday or Sunday's launch windows.

Though astronauts and other experts take such estimates with a grain of salt, NASA has calculated there's a 1-in-276 chance the crew may not survive the mission. An advanced emergency escape system will keep the danger to astronauts low during launch, though it can't help them once they reach space or during reentry through Earth's atmosphere.

Below are six live video broadcasts of the historic launch that you can watch, some online and some via TV channels. We've also provided a NASA timeline of launch-day events at the end of this post so that you can follow along.


NASA TV, the agency's livestreaming channel, plans to broadcast coverage of Saturday's launch attempt starting at at 11 a.m. ET. If the mission lifts off and Crew Dragon reaches orbit, NASA TV will show it docking to the space station, its hatch opening, and Behnken and Hurley joining the ISS crew. The agency's official TV channel also maintains a full and constantly updated schedule of its programming.


SpaceX started its first launch webcast around 12:15 p.m. ET via its YouTube channel. The production was jointly hosted with NASA, but John Insprucker — a top engineer at SpaceX — led the bulk of commentary for the rocket company. SpaceX has not yet said when its next launch broadcast will begin on Saturday.

National Geographic and ABC News Live

Journalists and meteorologists at National Geographic and ABC News covered SpaceX and NASA's first launch attempt with a two-hour special report that featured interviews with NASA astronauts and officials. Their broadcast on Saturday is set to begin at 3 p.m. ET — considerably shorter because weather has a 50% chance of foiling the launch, according to SpaceX.

Discovery and Science Channel

Both Discovery and Science Channel aired live coverage of SpaceX's first launch attempt Wednesday on TV and the Discovery Go app. The "Space Launch Live" special featured interviews with both Crew Dragon astronauts' spouses: the astronaut K. Megan McArthur, who is Behnken's wife, and the former astronaut Karen Nyberg, Hurley's wife. The singer Katy Perry also made an appearance. The channels will rebroadcast again on Saturday, according to Discovery's schedule.

The Museum of Flight

The Museum of Flight will re-broadcast its own live watch party at 2:30 p.m. ET on Saturday. Its Wednesday broadcast featured commentary from the retired astronaut Wendy Lawrence, the space-history curator Geoff Nunn, and the propulsion engineer Dieter M. Zube.

The times below are relative to liftoff at 3:22 p.m. ET on Saturday.

Once the crew lifts off, it will take SpaceX's new Crew Dragon spaceship about 12 minutes to reach orbit. Along the way, the Falcon 9 rocket will drop off its first-stage rocket booster (which SpaceX will try to land on a boat and recover), followed by its upper or second-stage rocket.

The capsule's automated systems or the crew's manual override could abort the mission at any time on the way to orbit. If there's any problem, the system should pull the Crew Dragon to safety and splash Behnken and Hurley down in the Atlantic Ocean, where recovery crews will try to meet them within an hour.
