**SpaceX has tested the simultaneous operation of 31 engines** on the first stage of the Super Heavy and set a **record for the number of simultaneous rocket engines in operation.** SpaceX conducted a hot-fire test of the first stage of the Super Heavy B7 on February 9, 2023 as part of the preparation for the upcoming first orbital launch of the Starship spacecraft. The simultaneous operation of 31 of the 33 Raptor rocket engines installed on the B7 booster was tested. Starship is a fully reusable, heavy-lift two-stage rocket system being developed by SpaceX. It consists of the starship spacecraft and the Super Heavy booster. The rocket has a diameter of 9 meters and a height of 120 meters, with 69 meters belonging to the first stage. The company is also developing methane-oxygen engines called Raptor 2, six of which are installed on the starship, with three optimized for operation in vacuum. The first stage has a record 33 engines, which is a record number for all rockets ever built (for example, the Soviet N-1 super heavy carrier rocket had 30 engines). Both components of the rocket are planned to be reusable. The company already has extensive experience with returning and reusing the first stages of the Falcon 9. It is expected that in its reusable form, the starship will be able to make point-to-point flights on Earth, as well as interplanetary missions to Mars and other destinations in the Solar System. @mr27.near, would you like to move to Mars at some point?
