SpaceX has improved the Starship Raptor engine for the lunar mission: 20% more thrust while reducing the mass by the same 20%

SpaceX has already shown an improved Raptor 2 engine for the Starship spacecraft – it is noticeably more compact than a conventional Raptor. And now there are a few more details about this.

SpaceX has improved the Starship Raptor engine for the lunar mission: 20% more thrust while reducing the mass by the same 20%

Everyday Astronaut’s Twitter account has posted two 3D models of the Raptor engine and its updated version, the Raptor 2, which is undergoing final testing. The authors suggested that the new engine has a mass of about 1600 kilograms versus 2000 kilograms for the old one. Elon Musk reacted to this message. He confirmed that the mass is indeed less by about 20%, and thrust, on the contrary, is more by 20%. However, the priority in the development of the Raptor 2, according to the head of SpaceX, is to increase reliability, facilitate production and reduce the price. Further improvement of spacecraft engines, according to Elon Musk, is the only way to make life multi-planetary and “expand consciousness.”

Thrust and dead weight are considered one of the most important characteristics of a rocket engine. Both can significantly increase the mass of the output payload or the fuel used.

SpaceX plans to power the Raptor (and Raptor 2) engines on the Starship, a next-generation, super-heavy, reusable rocket. It is with the help of this rocket and the spacecraft integrated into its upper stage that Elon Musk plans to send people to Mars and fulfill the NASA contract to deliver astronauts to the Moon by 2025-2026.

Conceptually, Starship will replace the current SpaceX rockets, that is, Starship will launch satellites into orbit, and deliver the crew to the ISS, and perform long-distance flights – to the Moon and later – to Mars. Accordingly, Raptor engines will be enough to perform simple missions, and Raptor 2 will be used for long-range and much more responsible missions.

Samsung Galaxy S23 smartphones are unlikely to receive a sub screen

Samsung is not considering adding under-screen front cameras to the Galaxy S23 line of smartphones. They were not in the Galaxy S22 either. This is stated on the Korean site Naver. A user under the pseudonym Ianzuk, citing sources in the supply chain, claims that Samsung does not have much confidence in the quality of this technology.

The source believes that the under-screen cameras do not yet match the quality of conventional front cameras. ZTE and Xiaomi also had similar problems. They also experimented with under-screen solutions, but failed to solve all the problems.

Even with the $1,799 Samsung Galaxy Z Fold 3, the quality of selfie shots was lower than with a regular camera. Therefore, according to the source, Samsung will not release a premium line with such cameras.

It was previously reported that the front cameras in the Galaxy S23 will receive more powerful image sensors with a resolution of 12 megapixels. And these smartphones are credited with the main camera with a resolution of 200 megapixels.

The embedded front camera in nova 10 has a familiar look, since it has only one module – with a 60-megapixel sensor.
