How to watch SpaceX Crew-4 astronauts launch to ISS

NASA Live: Official Stream of NASA TV

NASA and SpaceX are making final preparations for the launch of four astronauts to the International Space Station (ISS) from Kennedy Space Center’s Launch Complex 39A. The Crew-4 astronauts were originally supposed to launch on Saturday, April 23, but due to the late departure from the ISS of the Ax-1 mission, the mission won’t get underway until Wednesday, April 27, at the earliest.

NASA astronauts Kjell Lindgren, Bob Hines, and Jessica Watkins, together with Samantha Cristoforetti of the European Space Agency, will launch aboard a SpaceX Crew Dragon spacecraft atop a Falcon 9 rocket.

The flight will be SpaceX’s fourth operational crew transport mission, and the fifth crewed mission overall after the Dragon completed its first astronaut flight in 2020 in a demonstration mission.

What to expect

NASA’s livestream will show the astronauts making their way to the Falcon 9 rocket and being strapped into their seats inside the Crew Dragon capsule. Multiple cameras will also cover the rocket launch, stage separation, and the landing of the rocket’s first stage back on Earth. Later coverage will show the astronauts inside the spacecraft as they travel toward the ISS.

How to watch

A Falcon 9 rocket and Crew Dragon spacecraft carrying the Crew-4 astronauts is scheduled to lift off from Kennedy’s Launch Complex 39A at 3:52 a.m. ET (12:52 a.m. PT) on Wednesday, April 27.

The livestream will begin several hours earlier. You can watch it via the video player embedded at the top of this page or via NASA’s YouTube channel, which will carry the same feed. Clearly, the launch time isn’t great for folks in the U.S., but the stream will still be available first thing when you wake up on Wednesday.

The Crew Dragon spacecraft is scheduled to reach the ISS about 24 hours after launch, followed by the autonomous docking, hatch opening, and welcoming ceremony, where the crew will get to meet their counterparts on the ISS for the first time.

There’s a chance that a technical issue or poor weather conditions could delay the launch, so be sure to check this page or NASA’s Twitter feed for the latest updates.

In the meantime, check out NASA’s recently posted video showing the Crew-4 astronauts preparing for their mission.

SpaceX Dragon to give the International Space Station an altitude boost today
A SpaceX Crew Dragon spacecraft docked at the space station.

Friday will see a new event for the International Space Station (ISS) as a SpaceX Dragon spacecraft is used to boost its altitude for the first time. As drag works on the space station, its altitude gradually degrades over time, and so it needs to be given an occasional push to keep it at its correct altitude, around 250 miles from the Earth's surface.

The reboost is scheduled for today, November 8, as one of the Dragons that is currently docked to the space station will fire its thrusters for around 12.5 minutes. There are currently two Dragons docked -- one of which carried crew and one of which carried cargo to the station. The cargo vehicle will perform the boost maneuver. As this is the first time this has been attempted, NASA and SpaceX personnel will observe the event carefully.

What to expect from SpaceX’s sixth megarocket test flight
SpaceX's Super Heavy launch during the fifth test flight of the Starship.

As it unleashes a record 17 million pounds of thrust at launch, the sight of SpaceX’s 120-meter-tall Starship rocket roaring skyward is something to behold.

The Elon Musk-led spaceflight company has already performed five Starship flights since the first one in April 2023, with each one more successful than the last. Comprising the upper-stage Starship spacecraft and the first-stage Super Heavy booster (collectively known as the Starship), the giant vehicle willo be used by NASA for crew and cargo missions to the moon, Mars, and possibly beyond.

SpaceX has revealed that it is targeting Monday, November 18, for the sixth test of the Starship, the world’s most powerful rocket comprising the first-stage Super Heavy booster and the upper-stage Starship spacecraft.

The massive vehicle, which creates around 17 million pounds of thrust at launch, is set to be used by NASA for crew and cargo missions to the moon, and possibly even Mars, though there’s still much testing to be done.
