SpaceX postponed the launch of its massive Starship V3 rocket on Thursday (May 21) after the spacecraft had already been fully fueled at the company’s newly built launch facility in Starbase, southern Texas. A 90-minute launch window opened at 6:30 pm ET, but the rocket never lifted off. During the company’s live broadcast, SpaceX hosts confirmed they had ‘got the vehicle totally loaded’ before the launch was officially scrubbed. SpaceX has not announced an exact new launch time, though another attempt is expected on Friday (May 22).<h2>What is Starship V3, and why does the launch matter?</h2>The delayed mission involved Starship Version 3, the newest and most advanced version of SpaceX’s flagship rocket system. When fully stacked, the two-stage rocket stands 408 feet tall and produces 18 million pounds of thrust, making it the most powerful rocket ever developed by the company. According to SpaceX’s IPO prospectus filed Wednesday, the rocket is designed to “deliver 100 metric tons to Earth's orbit in a fully reusable configuration while enabling rapid turnaround times akin to commercial aviation.”&nbsp;Also Read: <a href="https://www.wionews.com/world/trump-announces-deployment-of-5-000-additional-us-troops-to-poland-as-tensions-with-nato-escalate-1779399664140">Trump announces deployment of 5,000 additional US troops to Poland as tensions with NATO escalate</a>&nbsp;Flight 12 was set to become the first test mission using the Version 3 upgrade.

No astronauts or operational payloads were onboard the rocket.

The test would provide valuable data for future deorbiting operations as SpaceX works toward fully orbital Starship missions. Unlike previous missions, Super Heavy Booster 19 was not expected to attempt a tower catch. Instead, the booster was scheduled for a controlled splashdown in the Gulf of Mexico around seven minutes after launch. Ship 39, the upper-stage spacecraft, was expected to complete its own controlled splashdown in the Indian Ocean more than an hour later.
