Core Viewpoint - The successful launch of the Shenzhou 21 manned spacecraft marks the beginning of a six-month mission for astronauts, supported by China's independently developed space kitchen, which has been operational for over 1500 days, ensuring the astronauts' dietary health [1][3]. Group 1: Space Kitchen Development - The space kitchen was developed to address challenges in providing astronauts with quality meals in the unique conditions of space, where heat conduction is poor and food heating is slow [1][3]. - The project began in 2013 when China's manned space program sought external research capabilities, leading to the selection of Joyoung, a small appliance company, in 2014 for its innovative technology [1][3]. Group 2: Technological Innovations - The space kitchen includes a water dispenser, hot air heating device, space soybean milk maker, and a smart app, which have successfully supported the dietary needs of multiple astronaut crews [3][5]. - The hot air heating device utilizes a unique "three-dimensional hot air circulation heating technology," allowing food to be heated in just 30 minutes, significantly improving meal quality for astronauts [3][5]. Group 3: Commercialization of Space Technology - Joyoung aims to leverage the technology developed for the space kitchen to enhance everyday life, introducing products like the ancient method health-preserving soybean milk maker and innovative rice cookers with precise temperature control [5][6]. - The application of space technology in consumer products demonstrates the potential for space innovations to benefit the general public, providing a valuable model for the effective transformation of space technology into civilian use [6].
