Elon Musk reveals why the SN10 Starship exploded

For a short while after SpaceX's SN10 Starship touched down on March 3rd, it seemed like the prototype made it out of its test flight unscathed. The vehicle exploded on its landing pad around a minute later, though, creating a massive inferno like its predecessorsdid. Now, Elon Musk has revealed what went wrong in responses sent to followers on Twitter. The SpaceX chief said the SN10 engine was low on thrust probably due to "partial helium ingestion from [the] fuel header tank" and that the impact crushed the rocket's legs and part of its skirt. SpaceX is now working on multiple fixes for the issue so that it doesn't affect SN10's successor, the SN11, anymore.

Chris Bergin of NASA Spaceflight tweeted that the issue is a "tricky one," seeing as the helium ingestion was caused by the pressurization system added to the CH4 tank to prevent what caused SN8 Starship's explosion. Musk said that's a "fair point," and he approved the change because it sounded good at the time.

SpaceX's Starship is a heavy-lift launch vehicle that's being developed to carry cargo and human passengers to Earth's orbit and beyond. SN10's explosion won't be slowing down the company's testing efforts — in fact, it recently rolled out the SN11 prototype to its Boca Chica facility to start preparing for its fourth high-altitude test launch.

Russia and China want to build an ‘international’ station on the Moon

Russia and China plan to work together to build a research station on the Moon. In an announcement spotted by Ars Technica, the two countries said they will collaborate on an “International Lunar Science Station.” There aren’t many details on the project yet, but Roscosmos, Russia’s national space agency, suggests it could include facilities both in orbit around the Moon and on its surface. It will also be open to other nations to join.

China and Russia were the two countries that were notably missing from NASA’s Artemis Accords. Announced in October, the agreement seeks to create a template for peaceful, cooperative and transparent exploration of the Moon. Dmitry Rogozin, the head of Roscosmos, said the Lunar Gateway, a space station NASA plans to build in orbit around the Moon as part of Project Artemis, was too “US-centric.” That’s despite the fact NASA and Roscosmos have collaborated productively for decades on the International Space Station and the same agreement that made the ISS possible will govern the Lunar Gateway. Rogozin later left open the possibility for the two space agencies to work together again, but with Roscosmos now partnering with China, the chances of that happening look much less likely.

New 3D printing technique could make lab-grown organs more practical

As much as 3D-printed organs have advanced, creating them is still a slow process that can damage the tissue. There may soon be a quicker and more effective method, however. Researchers from the University at Buffalo and elsewhere have developed a 3D...

A ferret is the first North American endangered animal to be cloned

Animal cloning might just become a valuable tool in preserving species that might otherwise go extinct. BBC News says US Fish and Wildlife Service has successfully cloned a black-footed ferret — the first genetic copy of a North American endangered s...
