SpaceX's Starship rocket generated impressive "mach diamonds" or "shock diamonds" as its 33 engines fired in unison during its recent test flight. The rocket booster successfully separated from the spacecraft before exploding over the Gulf of Mexico, while contact with the spacecraft was lost and the self-destruct feature had to be triggered. The Starship system aims to carry crew and cargo to Earth orbit, the Moon, Mars, and beyond, with its 33 engines producing a mind-boggling 16.7 million pounds of thrust.
