Without the Raptor V3, Starship would be massively overweight and would be much less important. Raptor V3 needs no heavy heat shields and no heavy fire suppression systems. With Starship soon having 42 Raptor engines, all these engines plus engine support systems add up to a lot of weight. We are talking about over 70 metric tons with the "light" Raptor V3 or over 150 metric tons with the original heavy Raptor V1. Most of the increase in lift capability between Starship V3 and V1 is due to lighter engines and engine support systems! (Starship V1 could lift about 15 tons while Starship V3 can lift 100 tons.) More info: The Raptor V3 is 3D-printed with channels that the cold fuel flows through to solve the problem of heat. By cold, we mean around -250F! (The special alloys that the engine is made of can handle about 2,200F so a little cooling goes a long way in helping out the engine.) Heat shields create enclosed spaces where dangerous gases can accumulate. Remove the heat shields, and then you don't need fire suppression. P.S. SpaceX has even more tricks up their sleeves. For example, they recently increased the amount of Starlink satellites per Falcon 9 launch by 30% simply by making the satellites much lighter.

BREAKING🚨: Astronaut Captures Rare Luminous Phenomenon from Earth Orbit. From hundreds of kilometers above Earth, an astronaut has photographed one of the planet’s most elusive atmospheric displays—an ethereal burst of light that flickers above thunderstorms. 😮 These phenomena, known as sprites or blue jets, briefly illuminate the upper reaches of the atmosphere, puzzling scientists and thrilling skywatchers. Recorded in stunning detail from orbit, the image reveals the extraordinary interplay between weather, electricity, and space

Godspeed Artemis II! Our crew on the @Space_Station stayed up to watch the launch of our friends on their historic mission to the Moon. We were over the Northern Pacific Ocean at the time of launch, so we couldn’t see it directly (we watched it on NASA TV). However, about a half hour later, as we orbited a few hundred kilometers from Florida, I was able to catch a glimpse of the remnants of the trail the rocket made as it passed through the atmosphere! You can see the effect of the wind at different altitudes.
