Core Viewpoint - The article discusses the emergency response initiated by China's manned space program following an anomaly with the Shenzhou-20 spacecraft, leading to the crew's transfer to Shenzhou-21 for their return to Earth and the launch of Shenzhou-22 for an emergency mission. Group 1: Emergency Response - On November 10, 2025, the Chinese manned space program officially activated an emergency plan due to an anomaly with Shenzhou-20, deciding to transfer the three astronauts to Shenzhou-21 for their return to Earth [1] - The Shenzhou-21 spacecraft will utilize a "3-circle autonomous rapid return" method, which was originally planned for the 2026 mission, but is now being implemented early due to the emergency situation [3] Group 2: Training and Preparation - The crew had to relearn procedures due to the change from a 5-circle return to a 3-circle return, which shortens the return time by three hours [5] - The astronauts engaged in multiple training sessions and discussions to familiarize themselves with the new manual and procedures for the return [8] Group 3: Emotional Aspects - The astronauts expressed feelings of reluctance and attachment to the space station after spending 204 days there, describing it as a home and a companion [10] - The farewell moment was filled with emotions, as the astronauts felt a deep connection to the space station [10] Group 4: Successful Return - On November 14, 2025, the Shenzhou-21 spacecraft successfully separated its orbital module from the return module, marking the beginning of the return journey for the astronauts [12] - The return process was noted to be well-prepared and executed, with the crew closely monitoring instrument parameters during the descent [14] - The new return method allowed for a smoother and quicker return, reducing the time from leaving the space station to landing on Earth by over three hours [16] Group 5: Record Achievement - The mission set a new record for the longest single crew stay in orbit for Chinese astronauts, with a total of 204 days [23] - Following the crew's return, Shenzhou-22 was launched on November 25, 2025, marking China's first emergency launch in manned spaceflight history [23]
