An image shared by Elon Musk earlier this month shows all 33 Raptor rocket engines installed on Starship.

As part of its launch campaign for its Mars rocket, Space Exploration Technologies Corporation (SpaceX) lifted the Super Heavy booster prototype of its Starship next generation rocket with a crane in its testing facilities in Boca Chica, Texas on Friday.

SpaceX's current rocket - the Falcon 9 - uses nine Merlin engines to lift payloads as heavy as 23 tons to low Earth orbit (LEO).

While the Falcon 9's Merlin 1D+ engine is capable of generating 221,000 pounds-force (lbf) of thrust, the Raptor 2 engines installed on Starship can push out  510,000 lbf of thrust, more than doubling the amount generated with the Merlin.

Additionally, not only is the Raptor 2 significantly more powerful, but as opposed to the nine engines present on the Falcon 9, the Starship Super Heavy booster has 33 Raptor 2 engines.
