Fei Junlong, Deng Qingming and Zhang Lu made their official public debut 57 days after returning from space. The recovery period of astronauts returning from normal flight in a group is mainly divided into three stages: isolation recovery, recuperation recovery, and recovery observation. Up to now, the Shenzhou 15 crew has completed the first two stages of work. On November 29, 2022, the Shenzhou 15 manned spacecraft flew into space, and then successfully achieved autonomous and rapid rendezvous and docking with the space station assembly. The Shenzhou 15 crew and the Shenzhou XIV crew "joined forces in space", starting the era of long-term manned presence on the Chinese space station. During a six-month stay in orbit, three astronauts completed four outbound missions, setting a new record for Chinese astronauts' single crew outbound activities. They celebrated the first Spring Festival after the completion of the space station and conducted more than 40 scientific experiments and technical verifications, known as the "Dream Crew". On July 31, astronaut Fei Junlong was answering questions from reporters. Guo Zhongzheng, a reporter from Xinhua News Agency, "It is our honor to participate in and witness the official completion of the Chinese space station in person," said Fei Junlong, the commander of the Shenzhou 15 crew. Fei Junlong realized his dream of flying to the sky for the first time in October 2005. After 17 years, he went to war for his country as commander for the second time. He said: "The mission of the two flights has changed, but the original mission to fight for the country, the non-stop preparation training, and the loyalty to pursue dreams for nine days have not changed." On July 31, astronaut Deng Qingming was answering questions from reporters. Guo Zhongzheng, a reporter from Xinhua News Agency, took a photo of more than 180 days and nights in space. Deng Qingming was most impressed by the first Spring Festival after the completion of the space station. "We received the blessing of the people all over the country in the sky. We were inspired to live up to the great trust of the party and people and resolutely complete the task." The four extravehicular flights were the highlights of the Shenzhou 15 crew, and Zhang Lu's most memorable extravehicular experience was the first time he asked the sky. "I was deeply shocked by the vastness of the universe outside the capsule. I thank all the scientific researchers for their companionship and support, which enabled us to successfully complete four extravehicular missions." Zhang Lu also talked about two "space conferences" with the Shenzhou XIV crew and the Shenzhou 16 crew. "The strong friendship between the three crew members is a mutual trust between life and death, as well as a continuation of the aerospace spirit." On July 31, astronaut Zhang Lu answered questions from reporters. At present, under the careful protection and care of the center's scientific research support team, the three astronauts are in good physical and mental condition, achieving the expected results, and have fully entered the recovery observation stage. After completing the summary of the recovery health assessment, they will switch to normal training work. "The pace of Chinese people's exploration of space will be more stable and further." Fei Junlong said, "We will cherish the honor, continue to work hard, and look forward to making new contributions to China's space industry." (Liu Yi, Zhan Kang) (Lixin News Agency)
