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

What actually happens when the Sun sends a powerful storm our way? ☀️ When the Sun erupts, it can release an intense solar flare followed by a fast-moving cloud of energised gas called a coronal mass ejection. Travelling at thousands of kilometres per second, these eruptions can disturb Earth’s magnetic field, accelerate energetic particles and trigger geomagnetic storms. On the ground, that can mean temporary radio interference, navigation issues and dazzling auroras. Thanks to our atmosphere a
