In a marathon orbital effort, Shenzhou-21 crew members upgraded the Tiangong Space Station's defenses yesterday (December 9, 2025) during China's first spacewalk of the month. The astronauts spent eight hours installing next-gen debris shielding – critical protection against space junk traveling at bullet-like speeds 🌌💥.
Mission control spokesperson Zhang Wei told reporters: "This upgrade ensures safer operations as we prepare for 2026's expanded scientific missions." The improvements come as China accelerates its lunar exploration roadmap, with Tiangong serving as a key testing ground for deep-space technologies 🔭🇨🇳.
