  "account": "Chinese scientists at Dalian University of Technology have devised a novel spacecraft armor design inspired by the shape of an egg to safeguard against space debris. This idea originates from the natural energy absorption capabilities of biological structures, as noted by lead researcher Yuxin Wang. In Earth's orbit, objects can travel at speeds ranging from 7 to 8 kilometers per second, with collisions potentially reaching velocities of up to 15 kilometers per second. To illustrate the dangers, a 1 cm aluminum sphere moving at 10 km/s carries the same kinetic energy as a hand grenade. As the number of satellites in orbit increases, the risk of collisions and subsequent debris buildup grows, with scenarios like Kessler syndrome becoming more likely. Wang's team created a model of their egg-shaped armor by sandwiching 3D-printed aluminum shells between two aluminum plates, filling the shells with water. They tested several configurations, finding that the design with pointy ends of the shells facing the impact surface reduced projectile velocity by 64.9 percent, compared to 51 percent for a single aluminum plate. The eggshells used in their tests were only 12 mm high, weighing less than half an inch while still effectively protecting the spacecraft. The researchers are currently optimizing their design and conducting further tests, advocating for the use of bio-inspired protective structures to combat the rising collision risks in Earth's orbit.",
