SpaceX's Starship Super Heavy rocket just launched seven engines first time (video)

The company is currently testing some engines from Booster 7's engines prior to the planned launch of its first launch of an orbital Starship.

SpaceX launched seven engines from the Starship Super Heavy prototype "Booster 7" on Monday (Sept. 19) which is the largest number of SpaceX's brand new Raptor engines tested to date simultaneously at exactly the same time.

The company is conducting tests on some the Booster 7's engines prior to the first planned mission to orbit of Starship, a 165-foot high (50 meters) spacecraft that is reusable and can be lifted into orbit using the 33 new generation Raptor engines in the Super Heavy booster, which is at 230 feet (70 meters) tall.

In preparation for Starship's first orbital flight SpaceX is conducting "static fire" tests in which one or more of the engines are lit while the vehicle is still on the ground.

In a follow-up tweet, Musk stated (opens in new tab) that "Booster 7 now returns to high bay for robustness upgrades & booster 8 moves to pad for testing," saying that the next major Starship testing will consist of the "full stack wet dress rehearsal, then 33 engine firing in a few weeks."

"The "full stack" consists of a Starship on top of an Super Heavy booster rocket, which together comprise the tallest rocket in the world at 395 feet high (120 meters).

The most recent SpaceX static fire increased by two the amount of machines that were used during its previous Super Heavy test conducted in August. 31. During that test, SpaceX ran a static fire using three Raptor engines.
