SpaceX will try to launch its Starship SN15 rocket in Texas today (updated)

Update: SpaceX has successfully launched and landed its Starship SN15 rocket. You can see a replay of the launch above. You can read our wrap story here.

SpaceX will attempt to launch its latest Starship prototype from the company's Starbase test site in South Texas Wednesday (May 5) with a liftoff targeted for 6:20 p.m. EDT (2220 GMT). 

Starship SN15 ("Serial No. 15"), SpaceX's newest vehicle, could fly on a high-altitude test from the company's facility near Boca Chica Village sometime between 1 p.m. and 9 p.m. EDT (1700-0100 GMT) on Wednesday, according to a road closure alert by officials with Cameron County, which includes the test site. Wednesday is a backup day for SpaceX, which originally had road closures from the country for May 4. 

The Federal Aviation Administration had issued all-day flight restriction notices for pilots in the area that through Friday (May 7) to give SpaceX clear skies for any launch attempt. By midday, the May 4 flight restriction had been lifted.

You can watch it live here and on the homepage, courtesy of a SpaceX webcast. SpaceX typically begins the webcasts 5 or 10 minutes before liftoff.

Last week, the Federal Aviation Administration (FAA) announced that it has authorized SpaceX's plans to launch SN15, as well as two more vehicles — SN16 and SN17 — in the weeks ahead. 

"The FAA has authorized the next three launches of the SpaceX Starship prototype," FAA officials wrote in a statement. "The agency approved multiple launches because SpaceX is making few changes to the launch vehicle and relied on the FAA's approved methodology to calculate the risk to the public. "

SN15 is SpaceX's fifth version of Starship to fly in less than five months. SpaceX conducted engine tests of the rocket earlier this week to set the stage for the upcoming launch.

The first Starship to fly, SN8, launched Dec. 9 and flew well, but crashed during landing. Each of the three other Starship flights (of SN9, SN10 and SN11), had similar fates. The SN10 launch did manage to land but exploded a few minutes after touchdown. None of those flights aimed for space, instead targeting an altitude of 6.2 miles (10 kilometers).

SpaceX is developing the Starship vehicle as part of a fully reusable heavy-lift launch system that will also include a massive booster called Super Heavy. SpaceX founder and CEO Elon Musk has said Starship will be the core of the company's deep-space rocket fleet for trips to the moon and Mars. 

NASA has tapped the Starship vehicle to land its Artemis astronauts on the moon. SpaceX has also sold a private flight around the moon using Starship to Japanese billionaire Yusaku Maezawa, who is searching for eight crewmembers to fly with him.
