3D-Printed Eggshell Arrays Filled With Water Boost Spacecraft Impact Resistance

·1 views

Researchers have developed a novel shielding material inspired by eggshell structures to better protect next-generation spacecraft. The design involves 3D-printed aluminum arrays modeled after eggshells, which are then filled with water. Testing showed this approach outperformed conventional shielding methods in resisting high-velocity impacts. The innovation could play a significant role in safeguarding future spacecraft from debris and micrometeorite collisions.

Sony clarifies disc production will drop only 10%, not 90%, by 2028

Sony has corrected a widely circulated misreport about the pace of its disc manufacturing wind-down. The company's disc division clarified that its Thalgau plant will produce only 10 percent fewer discs in 2028, not 90 percent fewer as was previously reported. The correction was shared by an unnamed Sony DADC spokesperson with games journalist Brian Crecente, two months after initial reports suggested the facility was already being repurposed. Sony's broader plan to phase out physical video game discs by January 2028 remains unchanged. The clarification suggests the transition away from disc production will be more gradual than earlier coverage implied.
