The “space business trip” has been in orbit for three months. What are the expectations for the second half?

Original title: The “space business trip” schedule is halfway through. What are the highlights in the first half and what are the expectations for the second half?

Since successfully entering the space station complex on November 30, 2022, the Shenzhou 15 astronaut crew has been working and living in orbit for three months. The "space business trip" schedule is more than halfway through. What are the highlights of the first half and what are the expectations for the second half?

The "Dream Crew" has passed the halfway point of its space mission and has achieved a number of phased results in three months in orbit

Recently, the Shenzhou 15 astronaut crew conducted its second extravehicular activity. With the close cooperation of the ground staff and the astronaut Deng Qingming in the cabin, the two extravehicular astronauts Fei Junlong and Zhang Lu successfully completed all the established tasks and returned safely to the Wentian laboratory cabin.

First-person perspective of astronauts setting up a high-temperature material cabinet

The Shenzhou 15 crew is working in orbit with a full schedule, and scientific experiments are their top priority. Not long ago, China's manned space program released footage of astronauts setting up a scientific experiment cabinet. Let's take a look from the astronauts' first-person perspective.

In the picture, astronauts are setting up a high-temperature material science experiment cabinet, which is a new type of experimental device that supports material preparation, processing, in-situ testing, real-time observation and diagnosis in the microgravity environment of the space station. The maximum heating temperature can reach 1600℃, and the temperature stability can reach ±0.25℃. The working temperature, stability, sample quantity and real-time observation imaging technology of this high-temperature material science experiment cabinet are at the international leading level.

The experimental cabinet contains a control module, a high-temperature furnace module, an X-ray projection imaging module, etc. Among them, X-ray projection imaging is the most distinctive. It can realize dynamic real-time imaging and observation of the material melting and solidification process, providing support for material science research in the space station.

The first ignition experiment of the Mengtian cabin combustion science cabinet was successfully carried out

Recently, with the cooperation of ground researchers and astronauts, the experimental system in the combustion science cabinet of the Mengtian capsule successfully carried out its first on-orbit ignition test. This ignition experiment used methane as fuel, and the two ignitions lasted for about 30 seconds. The experimental images transmitted by the high-speed camera clearly showed the morphology of the methane premixed flame surrounded by the diffusion flame. Space is a microgravity environment. How is combustion different from what we see on the ground? Why do we need to conduct this kind of space science combustion experiment?

News Review: Astronauts' colorful life in space

In a blink of an eye, the "Dream Crew" has been in orbit for three months. The work content is substantial and full. What kind of colorful life do Fei Junlong, Deng Qingming and Zhang Lu have in their spare time? Let's review it together.

In-orbit exercise is a project that the three astronauts have been carrying out continuously. Using space exercise equipment can keep them in good shape. In addition to the space treadmill and space bicycle, which are "veteran" exercise devices, the astronauts can also use the resistance exercise equipment in the Mengtian laboratory cabin to perform basic physical exercise movements such as rowing, squats, and deadlifts, effectively coping with the problems of weightless muscle atrophy and bone loss during long-term space flight.

In the space station, astronauts are all-round players. Not long ago, astronauts also experienced "on-orbit haircuts". In the picture, astronauts Fei Junlong and Zhang Lu worked together to cut Deng Qingming's hair. When cutting hair in the microgravity of the space station, you have to use a clipper to push the hair while using a vacuum cleaner-like device to suck away the hair stubble. You can't let it float around, otherwise it will bring safety hazards.

At this moment, the Chinese space station is flying around the earth. "Recording and taking photos" is an important part of the life of the "Dream Crew". This is the picture taken by the astronauts through the porthole from their home in space. The blue planet and the stars are so brilliant. We love the small space in front of us, and we will always chase the thousands of stars above our heads. Now that China's manned space flight has passed its "30th anniversary", we are chasing our dreams and looking to the sky. Let us look forward to more wonderful things together.
