SpaceX Starship Flight 4 Launch Time Revealed: Set your alarm for 8:50 a.m. EDT (1250 GMT) to watch the megarocket soar into space

BOCA CHICA, Texas — SpaceX is gearing up for the launch of its next Starship megarocket test flight on Thursday, June 6. The Starship Flight 4 test flight is scheduled to take place at the company’s Starbase facility in South Texas, with a targeted launch time of 8:50 a.m. EDT.

This test flight is crucial for SpaceX as it aims to demonstrate the ability of the Starship and Super Heavy booster to return and reuse. The Starship launch system is designed to be fully reusable and capable of flying to deep-space destinations such as the moon and Mars. NASA has even selected Starship to land its Artemis 3 astronauts on the moon in late 2026.

Following three previous test flights, SpaceX is hoping for a successful mission this time around. The previous attempts saw varying degrees of success, with the first two failing to reach space and the third managing to enter space but experiencing issues during reentry.

The upcoming test flight will see Starship and its Super Heavy booster, the world’s most powerful rocket, taking flight. The mission is expected to last just over one hour, with the Super Heavy booster flying for nearly 7 minutes before a planned controlled “landing” and soft splashdown in the Gulf of Mexico.

For those eager to watch the launch live, SpaceX will be offering a free live webcast of the event starting at 8:20 a.m. EDT. Viewers can tune in to SpaceX’s X account or’s VideoFromSpace YouTube channel for coverage of the launch.

In case the launch on June 6 is delayed, backup dates of June 7 and June 8 have been identified by officials in Cameron County, Texas, where SpaceX’s Starbase facility is located. These backup days will provide SpaceX with additional opportunities to conduct the test flight if needed.

Overall, the Starship Flight 4 test flight holds significant importance for SpaceX as it continues its quest to develop a fully reusable and robust spacecraft for future missions to the moon, Mars, and beyond.
