China's Shenzhou-21 astronauts are still crushing their cosmic to-do list after three months aboard the Tiangong space station! 🛰️ Commander Zhang Lu and crewmates Wu Fei and Zhang Hongzhang just wrapped another productive week of zero-gravity science and station upkeep – proving space exploration is equal parts lab coats and toolkits.
🧪 Science That’s Out of This World
The team collected blood samples to study how space alters bones and brain function – crucial data for future Mars missions! They also ran vision experiments to see how microgravity messes with our perception (spoiler: floating might make your eyes play tricks).
🔧 Maintenance Mode: Space Edition
Between experiments, the crew became orbital handymen: cleaning experiment chambers, fixing equipment with space-grade tools, and even doing window washing with a stellar view of Earth. Pro tip: You haven’t cleaned until you’ve wiped a space station observation portal!
💪 Keeping Fit Among the Stars
How do you stay swole in zero-G? The astronauts used special muscle stimulators during workouts and ran detailed health checks – including eye scans that look straight out of a sci-fi flick. Because nobody wants space-induced health issues when you’re 400 km above your nearest clinic.
With their samples set to return to Earth soon, these space pioneers are writing the playbook for humanity’s future among the stars. 🌌
