"Ask the sky" flies into the sky, and the space home exhibition is looking forward to it... On July 24, before the launch of the ask the sky experimental module, the Tianhe core module assembly passed over Hainan Island. The astronauts of Shenzhou 14, who watched the launch from space, took pictures of the beautiful Hainan Island. On the Wenchang space launch site under the camera of the astronauts, the sky inquiry experimental module is ready to set off and is about to embark on a flying journey. "Warmly welcome the space module to come to us from our motherland that we think about day and night. This is the first time in history that Chinese astronauts watch the launch mission in space and welcome the arrival of another module of the space station in the vast universe!" Astronaut Chen Dong said excitedly. 495 seconds after the successful launch, the mission of the long march 5B carrier rocket, which was responsible for transporting the sky inquiry experimental module into space, was successfully completed. "The space station's space capsule has accurately entered the scheduled orbit... The launch mission is a complete success!" The scientific researchers of Beijing aerospace flight control center quickly took over the "baton", and the exciting next segment of the journey has begun. "Ask the sky" connects "Tianhe", and China Aerospace is about to stage a "heavyweight" kiss of space "! Strings of data on the computer screen kept rolling, and instructions came and went... In the brightly lit flight control hall, all the researchers present focused on the space more than 300 kilometers away. Two 20 ton spacecraft, the Wentian experimental module and the Tianhe core module, are moving at a speed of about 7.9 kilometers per second. Enter the sunny area, implement the manned environment state setting, and manually inject the rendezvous and docking flight procedures... Key links were successfully completed. Tick, tick... The beat of the second hand is so clear; Plop, plop... The heart beats faster and faster. In the eyes of countless people, at 0:05 on the 25th, the Wentian experimental module reached a place about 5 kilometers away from the Tianhe core module. The distance between the two spacecraft is getting closer and closer, and the relative speed is getting smaller and smaller. In the final stage, although the two are still moving at a high speed, the relative speed gradually drops to 0.1 meters per second. "400 meters close... 400 meters keep... 200 meters close... 200 meters keep..." in nearly an hour, the two spacecraft slowly approached. Close, keep, close, keep, "ask the sky" and "Tianhe" are getting closer and closer. Everyone's eyes move with the cross target on the docking mechanism. Align and then align until they are firmly connected. At 3:13 on the 25th, amid warm applause, came the powerful password voice of the Beijing chief dispatcher: "the docking mechanism between the test module and the Tianhe core module is locked, the assembly is started and controlled, the rendezvous and docking are completed normally, and the follow-up work is implemented according to the normal flight control plan!" The "new home" arrived smoothly, and the Shenzhou 14 astronaut crew then entered in the spotlight. From the perspective of Tianhe panoramic camera, the nearly 56 meter solar wing has been fully expanded, dazzling in space. Astronauts Chen Dong, wearing headlights and goggles, holding an air measuring instrument, opened the balance valve to ensure pressure balance and then opened the hatch. "Open! Open!" Someone whispered and cheered. On the large screen of the Beijing aerospace flight control center, the hatch was opened, and people were excited. Chen Dong continued to open the second door, the docking door of the Wentian experimental module. The reporter saw from the large screen real-time picture of the Beijing aerospace flight control center that Chen Dong took out a special "key" - a metal handle 30 to 40 cm long. He turned the handle, which was equivalent to putting a "nut" on the "nut" of the door opening mechanism, and slowly twisted... Chen Dong was the first to float into the space capsule, and saw rows of cargo bags neatly placed on the white ground in the spacious and bright cabin... Then, astronauts Liu Yang and CAI xuzhe entered in turn. This is the first time that China's two 20 ton spacecraft have achieved rendezvous and docking in orbit, and it is also the first time that China's space station has astronauts during their stay in orbit. At 10:03 on the 25th, all the astronauts of Shenzhou 14 arrived at the "new home". Three astronauts stood in a row to salute the motherland and the people. The working cabin of Wentian experimental cabin is the largest single sealed cabin in China so far. There are 3 sleeping areas and 1 sanitary area in the cabin, loaded with 8 experimental cabinets and 22 extravehicular load adapters, which is equivalent to moving a large scientific laboratory into space. Since then, Chinese people can also carry out large-scale space science experiments in space! The exciting words of the three astronauts echoed between heaven and earth - "this is the second working and living module we have in space. The construction of the Chinese space station has taken another big step forward, and we are extremely proud and happy!" "Looking forward, looking forward, we have welcomed the 'ask the sky' partner. From today on, the space station has entered the era of multi segment operation, and our space home will be more and more beautiful!" "We will continue to work hard to build, maintain and operate our space station, and live up to the expectations of the party and the people!" History will remember this moment! (outlook new era)
