“太空烧烤”食材如何锁鲜？探秘·轻舟货运飞船用最前沿科技为太空带去人间烟火

Core Viewpoint - The "Light Boat" cargo spacecraft developed by the Chinese Academy of Sciences has completed key technology validations and has entered the overall testing phase, aiming to undertake low-cost cargo transportation tasks for the Chinese space station [1][3]. Group 1: Technical Specifications - The Light Boat cargo spacecraft consists of a sealed main cabin and an unsealed tail section, resembling a large sealed box with a pickup truck's cargo bed, allowing it to carry precision instruments and necessary supplies [6]. - The spacecraft can carry 1.8 tons of cargo to the space station and is also responsible for collecting waste and old equipment from the station, ensuring no debris is left behind upon re-entry [11]. Group 2: Features and Innovations - The cargo hold of the Light Boat includes a modular cold chain system, functioning like a "space refrigerator," with each module having a capacity of 60 liters, allowing for flexible configurations up to 300 liters total [13]. - The spacecraft is equipped with AI management for cargo, enabling astronauts to quickly locate items through voice interaction, enhancing efficiency and convenience in space living [15]. Group 3: Economic Aspects - The current transportation cost for this "interstellar delivery" service is approximately 100,000 yuan per kilogram, with expectations that costs will decrease with mass production and the involvement of commercial space ventures [17].
