Engineers have long assumed that heating metals always softens them, but how metals behave at extreme deformation rates remained unclear. This counterintuitive finding reframes purity as a design ...

When a spacecraft re-enters Earth’s atmosphere, it must withstand temperatures of up to 3870°C. Here, inside NASA’s Arc Jet Complex at the Ames Research Centre in California, a heat-shield design is ...

LONDON - The word on the Chinese street is that metals are the next hot thing. All you need to join the bull party is an online trading account, a bit of cash for the initial margin and access to the ...

SpaceX fitted metal tiles on Starship’s exterior only to see them oxidize rapidly during reentry, turning streaks of stainless steel into rusty orange: a sign the tiles couldn’t handle the ...

Getting to space is hard. In many ways, getting back is even harder. NASA soon aims to pull off the kind of re-entry it last conducted more than 50 years ago: safely returning astronauts to Earth ...

SpaceX removed about 72 tiles in 18 key locations for Starship Flight 11 and there was no catastrophic failure. This could allow SpaceX to optimize the heat shield and remove 10-20% of tiles over ...

SpaceX has a new heatshield solution that is called the crunchwrap. ChromeKiwi has some graphics that explain it. SpaceX has decided they need to seal the tiles. Metal heat shield tiles had heavy ...

SpaceX’s more than 400-foot-tall Starship rocket returned to form Tuesday, deploying its first payload and completing critical heat shield tests following a string of in-flight and preflight failures.

Gold and silver are on an incredible run amid rising trade and macro unknowns. A number of big banks see higher highs for both precious metals in the second half of 2025. Are you ahead, or behind on ...
