Another fun fact is that SpaceX just successfully completed its 34th launch of 2023 today. Counting 10 Merlin engines (9 booster and 1 upper stage) for each of the 32 Falcon 9 launches and 28 engines each (9 on each of the core and two side boosters, one on the upper stage) for the two Falcon Heavy launches, that’s a total of 376 SpaceX engines which have launched orbital payloads so far in 2023.
