Scientists have achieved a breakthrough that could revolutionise space exploration with a "smart" metal alloy that remembers its shape even in the bone chilling cold of outer space. This remarkable copper based material can be twisted and deformed when cold, then automatically snap back to its original form when heated, maintaining this mechanical "memory" at temperatures as extreme as -200°C. The discovery solves a critical challenge that has limited spacecraft design for decades, opening the door to more reliable satellites, space telescopes, and future missions to the frozen reaches of our Solar System and beyond.
