Imagine an asteroid so rich in metals it could make everyone on Earth a billionaire. 💰☄️ This newly spotlighted space rock valued at $700 quintillion is packed with gold, platinum, and rare elements we barely find on Earth. If we could mine it, it would completely transform the global economy. Of course, reaching and extracting material from it is a huge challenge. But with space agencies and private companies exploring asteroid mining tech, what once seemed like science fiction is slowly movin

What does metal made in space look like up close? 🤘 Thanks to our first metal 3D printer aboard the @iss, we’re finding out. This pioneering device melted stainless steel in microgravity to build a complete test sample - layer by layer - before sending it back to Earth for analysis. Now, our engineers are examining every ridge, pore and flaws to understand how printing behaves beyond our planet. Why does this matter? Because future astronauts will need to make tools, replacement parts and maybe
