Chengli Group's medical monitoring truck bulk order ceremony. The three orange special vehicles in the image are astronaut medical monitoring trucks specifically built for China's space missions, serving as "life support capsules" when Shenzhou-series astronauts return. The interior space is approximately 12m2, accommodating one astronaut and a full set of medical support equipment, with single-vehicle crew support ensuring privacy and dedicated service. Equipped with a small operating table, vital signs monitor, CT scanning system, and life support module, it can provide basic medical care inside the cabin. It also adjusts temperature, humidity, and air pressure to simulate microgravity conditions, helping astronauts adapt to ground gravity. Features sensor-activated doors that open in 0.3 seconds, rapidly establishing a safe passage for astronauts in extreme environments like sandstorms and low temperatures.
