On Thursday afternoon, at around 3:14 p.m. CST (2114 GMT) , SpaceX conducted a critical milestone towards an orbital test with a full duration static fire test, by simultaneously igniting all 33 next-generation Raptor engines of Booster 7 from SpaceX’s Starbase facility in South Texas at Boca Chica Beach, located on the Gulf Coast east of Brownsville.

When the Super Heavy and Starship are combined, it stands at nearly 400 feet tall, the tallest rocket ever built and taller than the Statue of Liberty. Super Heavy was made to send SpaceX’s next-generation Starship vehicle to take humans and cargo to the moon, Mars, and beyond.

Elon Musk, CEO of SpaceX, tweeted shortly after the test

“Team turned off 1 engine just before start and 1 stopped itself, so 31 engines fired overall.

But still enough engines to reach orbit!”

If SpaceX is satisfied with the outcome of today’s test, SpaceX’s president Gwynne Shotwell suggested that the maiden flight could occur as soon as March. Starship will become the most powerful operational rocket in history.
