Update for April 17, 12 a.m. EDT: SpaceX is now targeting 9 a.m. EDT (1300 GMT/8 a.m. CDT) for the launch of its first Starship and Super Heavy booster. The launch webcast is expected to begin at 8:15 a.m. EDT (1215 GMT).

When SpaceX attempts to launch its Starship, the world's biggest rocket, for the first time today (April 17), the world will be watching and you can, too, with a free webcast from the private spaceflight company.

SpaceX's first Starship test flight is currently set to launch from the company's Starbase facility near Boca Chica Village in South Texas, with liftoff targeted for 9 a.m. EDT (8 a.m. CDT/1300 GMT) at the start of a launch window that runs for 150 minutes (through 10:30 a.m. EDT/1430 GMT). SpaceX's webcast is scheduled to begin 45 minutes before liftoff, making its start at 8:15 a.m. EDT (1215 GMT). You can watch it live above and on the Space.com homepage at start time, or watch it directly from SpaceX's webcast (opens in new tab) and its YouTube channel (opens in new tab).

"Success maybe, excitement guaranteed!" SpaceX founder Elon Musk wrote on Twitter after the company secured its Starship launch license from the Federal Aviation Administration late Friday (April 14).

SpaceX's first nearly orbital Starship launch will launch the company's Starship SN24 prototype on a Super Heavy booster (called Booster 7) to prove the viability of the company's next-generation launch system, which is designed to eventually be fully reusable. It stands a whopping 395 feet tall (120 meters), making it the world's tallest and most powerful rocket. Its Super Heavy first stage alone is powered by 33 methane-fueled Raptor engines.

SpaceX will use Starship to land NASA's Artemis 3 astronauts on the moon in 2025, and plans to use the spacecraft for at least three private spaceflights, two of them to carry passengers around the moon. Starship is also SpaceX's planned go-to vehicle to fly astronauts to Mars as part of the company's long-term goal of settling the Red Planet.

"Starship is a fully reusable transportation system designed to carry both crew and cargo to Earth orbit, help humanity return to the Moon, and travel to Mars and beyond," SpaceX wrote in a mission description (opens in new tab). "With a test such as this, success is measured by how much we can learn, which will inform and improve the probability of success in the future as SpaceX rapidly advances development of Starship."
