SpaceX is just a day away from its first Starship test flight of the summer, and if you're hoping to watch the world's largest rocket lift off, you'll need to know where and when to tune in. But don't worry — we've got you covered.The next Starship test flight, called Flight 13 (SpaceX doesn't appear to be superstitious), is scheduled to launch from the company's test site in Starbase, Texas near Boca Chica Beach on Thursday, July 16. Liftoff is set for 6:45 p.m. EDT (2245 GMT).As its name suggests, the upcoming flight will be the 13th test launch overall of SpaceX's Starship megarocket. It will be the second such flight this year, after the May 22 launch of Starship Flight 12. SpaceX is designing Starship, which stands more than 400 feet (121 meters) tall, to be a fully reusable rocket capable of launching missions to the moon, Mars or beyond.NASA picked Starship to land its Artemis IV astronauts on the moon by 2028, and SpaceX has sold at least one Starship passenger flight to Mars as well. But before SpaceX can carry astronauts to other worlds with Starship, it has to complete a series of suborbital flights and, eventually, reach Earth orbit for in-flight fueling tests, docking demonstrations and more.SpaceX's Starship Flight 13 is a suborbital test that will be the second flight of SpaceX's new V3 Starship. Below you'll find details on what time Flight 13 will launch, what the mission will do and a full timeline for the mission.What time is SpaceX's Starship Flight 13 launch?
