You should know that it took more than 10 years to launch the first section of the International Space Station from the launch of the first section to the completion of the on-orbit construction work, and as many as 16 countries participated. It can be said that the International Space Station has been built and operated so far, and it is inseparable from 16 participating countries. Of course, the United States and Russia have played a very important role in it. The other 14 countries have relatively less money and efforts. We completed the construction of the space station on track with our own strength within more than a year, which shows that our country's scientific and technological strength is very strong.
Mengtian Experimental Cabin launches
I believe everyone is waiting for the good news from Mengtian Experimental Cabin during this period, and now the good news is coming again! On October 25, 2022, the Mengtian Experimental Cabin and the
combination of the Long March 5 B Yao-4 carrier rocket have been transported to the launch area. A series of functional inspections and joint testing will be carried out before the launch, and will be launched at an appropriate time. Judging from the situation of the Tianhe core module, the Wentian experimental module and other spacecraft we launched before, transfer to the launch area actually means that the preparations before launch have been completed and are ready, and you only need to wait for the arrival of the launch window.
If you are launching a separate spacecraft, the requirements for the launch window may not be that high, but when launching the spacecraft to the space station assembly, the requirements for the launch window are very high, and it does not mean that it can be launched at any time. Because the space station assembly is flying at a high speed of 27.9 kilometers in low-Earth orbit, the Dream Sky Experimental Cabin will arrive at a faster speed near the space station assembly after launching and rendezvousing and docking. If the launch time is too early, the space station assembly will be missed. If the launch time is too late, the space station assembly will not be able to keep up with the space station assembly. If the space station assembly is missed, if you want to continue to complete the rendezvous and docking, you need to consume a lot of fuel to adjust the flight orbit, which is not worth the effort. The Wentian Experimental Cabin before
was also launched using a "zero window", which means that the time of the rocket launch and the time of the predetermined ignition cannot exceed 1 second. If you miss this launch window due to weather or other reasons, you will wait for the next window to arrive before re-launching. This is enough to show how difficult it is to launch a spacecraft to the space station. Not all countries have the ability to supply spacecraft to launch spacecraft.
Now Mengtian Experimental Cabin is ready to go, and the launch time is getting closer and closer. After this experimental cabin is launched, we will have two more launch missions by the end of this year, one of which is to launch the Tianzhou 5 cargo spacecraft, and the other is to launch the Shenzhou 15 manned spacecraft. Both missions will be launched before the Shenzhou 14 spacecraft returns to Earth. In other words, by the end of this year, we will have two manned spacecraft, Shenzhou 14 and Shenzhou 15, docking with the space station, and then six astronauts will live and work in the space station at the same time. In fact, at this stage, our space station has already met the living of 6 astronauts in orbit, because the Tianhe core module has 3 sleeping areas, the Wentian Experimental Column also has 3 sleeping areas, and the entire space station has 2 health areas, which can meet the short-term 6 people's residence.
European female astronaut said Chinese
Since the launch time of the Mengtian experimental cabin has been announced before, everyone is paying attention to the progress of the Mengtian experimental cabin during this period.I believe that in addition to following the Mengtian Experimental Cabin, many friends are also following . The European Space Agency's female astronaut Samantha Christo Forreti. Because on October 12, 2022, when the International Space Station flew over Beijing, the female astronaut posted a verse from "Preface to the Lanting Collection" on Twitter, with the English and Italian translation. She quoted verses from "Preface to the Lanting Collection" to express her mood when she looked down at the world.
This makes people feel a little incredible, because many friends may not remember the poem in "Preface to the Lanting Collection", but this female astronaut showed off her Chinese at the International Space Station, so many friends said that she had shown it, and even claimed that her level of ancient Chinese may not be as good as this foreign female astronaut, and they all praised her Chinese level.
Seeing this foreign female astronaut speaking Chinese, many friends also began to think of the Chinese space station because our space station welcomes foreign astronauts to participate. A very important condition for foreign astronauts to enter the Chinese space station is to have a relatively high Chinese level, because the control interfaces of the Chinese space station are all in Chinese. If the Chinese level is not good, they will not be able to understand the interfaces of the Chinese space station. Christoforetti showed off her Chinese, which made many people start to wonder whether she will really become the first foreign astronaut to enter our Chinese space station next.
has such a speculation, which is actually reasonable, because she has come to our China before to participate in joint aerospace training. In 2017, Christoforetti and our astronauts conducted a maritime survival exercise in the Yellow Sea of China. In a previous interview with CCTV, Christoforetti also showed excellent Chinese skills. However, whether it will enter the Chinese space station will also take into account many factors, such as whether the time is running. After all, Christoforetti is also participating in the mission of the International Space Station.
