00:00To put it simply, Raptor 2 is much more streamlined, built more simply and optimized for mass production.
00:07Specifically, this usually means a simplification of the engine's architecture.
00:11At 1.6 tons, Raptor 2 also weighs 400 kilograms less than Raptor 1.
00:17As if all that weren't already massive improvements, at 230 tons,
00:22Raptor 2 delivers almost 25 more thrust than its predecessor and doesn't operate at 250.
00:30But there's a combustion chamber pressure of 300 bar.
00:33That's as much pressure as at a depth of 3,000 meters.
00:37We've seen what deep water can do.
00:39Until 2019, the Soviet RD-180 engine held the record with a chamber pressure of 257 bar.
00:46That's when SpaceX broke the record, when Raptor 1 fired at 270 bar
00:53and lifted Starhopper into the air for a short hop before Starhopper landed again.
