What are the highlights of the first half of the "Dream Crew" space business trip? What are the expectations for the second half?
Since successfully entering the space station complex on November 30, 2022, the crew of Shenzhou 15 astronauts have been working and living in orbit for 3 full months.
The "space business trip" is halfway through the schedule, what are the highlights of the first half, and what are the expectations for the second half?
The "Dream Crew" space travel schedule has achieved a number of phased results in orbit for three months
Recently, the crew of Shenzhou 15 carried out the second extravehicular activity.
With the close cooperation of the ground staff and the astronaut Deng Qingming in the cabin, the two out-of-vehicle astronauts Fei Junlong and Zhang Lu successfully completed all the scheduled tasks and returned safely to the Wentian experimental cabin.
First-person experience of astronauts setting up high-temperature material cabinets
The crew of Shenzhou 15 is working in orbit with a full load of tasks, and scientific experiments are their top priority.
Not long ago, China's manned spaceflight released a picture of astronauts setting up scientific experiment cabinets.
We take a look through the astronaut's first-person perspective.
In the picture, the astronauts are setting up the high-temperature material science experiment cabinet, which is a new experimental device that supports material preparation, processing, in-situ detection, real-time observation and diagnosis in the microgravity environment of the space station.
The maximum heating temperature can reach 1600°C, and the temperature stability can reach ±0.25°C. The working temperature, stability, number of samples, and real-time observation and imaging technology of this high-temperature material science experiment cabinet are all at the international leading level.
The experimental cabinet contains control modules, high-temperature furnace modules, X-ray projection imaging modules, etc. Among them, X-ray projection imaging is the most distinctive. It can realize dynamic real-time imaging and observation of the melting and solidification process of materials, and provide support for the material science research of the space station. .
Mengtiancai Combustion Science Cabinet successfully implemented the first ignition experiment
Recently, with the cooperation of ground researchers and astronauts, the experimental system in the Mengtiancai combustion science cabinet successfully performed the first on-orbit ignition test.
In this ignition experiment, methane was used as fuel, and the ignition lasted for about 30 seconds twice. The experimental images transmitted by the high-speed camera clearly showed the appearance of the methane premixed flame surrounded by the diffusion flame.
There is a microgravity environment in space, so what is the difference between combustion and what you see on the ground? Why is this kind of space science combustion experiment conducted?
News Review: Astronauts live a colorful life in space
In a blink of an eye, the "Dream Crew" has been in orbit for three months, and the work content is full and full. After work, what kind of colorful space life do Fei Junlong, Deng Qingming, and Zhang Lu have?
Let's review together.
On-orbit exercise is a continuous project for the three astronauts, and the use of space exercise equipment can keep them in good condition.
In addition to space treadmills, space bicycles, and other "veteran-level" exercise devices, astronauts can also perform basic physical exercises such as rowing, squats, and deadlifts with the help of the resistance exercise device in the Mengtian experimental cabin, effectively coping with long-term exercise. Problems with weightlessness muscle atrophy and bone loss in spaceflight.
On the space station, astronauts can be described as all-round players. Not long ago, astronauts also experienced an "on-orbit haircut".
In the picture, astronaut Fei Junlong and Zhang Lu cooperated to cut Deng Qingming's hair.
To get a haircut on a space station in microgravity, you need to push it with a clipper while using a device like a vacuum cleaner to suck up the hair stubble, and you can't let it float freely, otherwise it will bring safety hazards.
At this moment, the Chinese space station is flying around the earth, and "recording and taking pictures" is an important part of the life of the "dream crew".
This is the picture taken by the astronauts through the porthole from the space home. The blue planet, with a little bit of starlight, is extremely brilliant.
We love the square inch in front of us, and we will always chase the thousands of stars above our heads.
Today, China's manned spaceflight has passed its "Thirty Years". Let us look forward to more exciting things together.
