China's space station sets record with containerless experiment

00:22

China's space station has set a new world record after its containerless materials experiment heated a tungsten alloy beyond 3,100 degrees Celsius inside the Tianhe core module. Using microgravity "levitation" and a dual-wavelength laser heating system, scientists were able to melt ultra-heat-resistant alloys without container interference. The experiment provides crucial data on how these materials behave under extreme temperatures, paving the way for breakthroughs in spacecraft shielding and rocket engine components.
