For example, in June this year, the Long March-2D rocket successfully launched 41 satellites, setting a new record for China's "one arrow with multiple satellites". The Long March 5 rocket, which has a more powerful carrying capacity, was mainly used to launch the three modules of the space station, the Tianwen-1 probe and the Chang'e-5 probe. 
Due to the frequent launch of satellites, when satellites are launched now, everyone's attention is actually very low. In fact, not only is the attention paid to launching satellites not high, but the attention to manned spaceflight seems to be declining, after all, our Long March series rockets have been launched more than 500 times. 
Taking manned spaceflight as an example, in October this year, we launched the Shenzhou-17 manned spacecraft, and the Shenzhou-16 spacecraft also returned to Earth at the end of October. Compared with the previous manned spacecraft such as the Shenzhou 12 spacecraft and the Shenzhou 13 spacecraft, the Shenzhou 17 spacecraft does not seem to be so hot. This shows that our manned spaceflight has entered a normalized affair and has become a commonplace launch mission, and the attention has naturally declined. 
However, there are exceptions, at about 9 p.m. on December 15, a Long March 5 Yao-6 carrier rocket took off from the 101 launch pad at the Wenchang Cosmodrome, successfully sending a satellite to the predetermined orbit, and the launch mission was a complete success. 
Although we have dozens of launch missions this year, this launch mission has attracted much attention and aroused heated discussions among major netizens. Because the launch of the satellite this time is the famous Long March 5 rocket, and the Long March 5 rocket is the most powerful carrying capacity in China's current service. What kind of satellite does it need to use the Fat 5 rocket with the strongest carrying capacity?
The reason for everyone's attention is not only the use of the Long March 5 rocket, but also because this rocket is an extended version. In previous missions, the Long March 5 rocket had a fairing diameter of 52 meters, height 12267 meters, and the fairing for this launch mission was larger, and for the first time a newly developed diameter of 5 was used2 meters, 18 meters high5 meters fairing. 
Previously, the fairing with a height of more than 12 meters could fit the three modules of the space station, and the length of the fairing of this Long March 5 Yao-6 launch vehicle is actually more than 6 meters longer than the previous fairing. The fairing is larger in size and can accommodate larger payloads. 
Due to the increase in the length of the fairing of the Long March 5 Yao-6 launch vehicle by several meters, the height of this rocket exceeds that of all Long March series launch vehicles in service, making it the highest launch vehicle in service in China. 
It is no wonder that when the Long March 5 Yao-6 carrier rocket was ready to launch, everyone had begun to pay attention to this launch mission, and they all wanted to know what kind of satellite it launched this time, why it used the Fat Five, and it was the Fat Five with a fairing that was lengthened by more than 6 meters. 
The need to dispatch the Long March 5 rocket to carry out the launch mission shows that the size and tonnage of this satellite must be not small, and if it is a very small satellite, other rockets can complete the launch mission. So what kind of satellite is this?
According to reports, the Long March 5 Yao-6 launch vehicle launched the remote sensing 41 satellite. This is a high-orbit optical remote sensing satellite developed by the Fifth Academy of China Aerospace Science and Technology Corporation, which is mainly used to carry out land census, crop yield estimation, environmental management, meteorological early warning and forecasting, and comprehensive disaster prevention and mitigation, and provide services for economic development.
For everyone, the words remote sensing satellite are not unfamiliar. According to the data released in the "China Geographic Information Industry Development Report (2023)", as of the end of 2022, there are 294 civil remote sensing satellites in orbit in China, including 189 commercial remote sensing satellites.
In the past, when we launched remote sensing satellites, everyone's attention was not very high, but now everyone is paying attention to the remote sensing 41 satellite, mainly because this satellite uses an extended version of the Long March 5 rocket. In fact, this also shows that the remote sensing No. 41 satellite should be more advanced than the past in terms of functions and other aspects.
