I have to say that Fat Wu is also quite desperate in order not to become "Mrs. Niu"!
A few days ago, the mainland successfully launched the remote sensing 41 satellite from the Wenchang Cosmodrome using the Long March 5 Yao-6 carrier rocket, and the satellite successfully entered the predetermined orbit, and the launch mission was a complete success.
This is the first time in three years, Fat Five is currently the highest rocket in the mainland, and it will fly again!
Back then, Fat Five was the little sweetie that the whole network paid attention to, and every launch was eye-catching.
And this time it is even more so, some people may ask, China's launch of rockets, isn't it just commonplace?
Long March 5 launch
Fat Five, as the strongest member of the mainland's active Long March carrier rocket, can be said to be full of credit.
Its core stage has a diameter of 5 meters, bundles four 3.35-meter boosters, a take-off thrust of more than 1,000 tons, and has a carrying capacity of 25 tons in low-earth orbit and 14 tons in geosynchronous transfer orbit.
Its last launch was on November 24, 2020, when it sent the Chang'e-5 probe to the moon.
And this time the Chang-5 rocket is different from the past, first of all, it has become taller.
Due to the use of the newly developed 5.2 meters in diameter, 18.5 meters long version of the fairing, the height of the whole arrow has been increased to about 63 meters.
You must know that the fairing of the Chang-5 rocket was 12.267 meters high, but this time it has been increased by more than 6 meters, which can be called a major change.
The increase in altitude has made the Chang-5 long-range 6 rocket surpass all the Long March series carrier rockets in service, and become the highest carrier rocket in service in mainland China and even Asia.
At the same time, the use of "extended" fairings also means that larger payloads can be accommodated. For example, this time, it was carrying the domestically developed remote sensing No. 41 satellite.
What is this satellite for? Anyway, the official press release is still the same as before.
This satellite is a high-orbit optical remote sensing satellite, which is mainly used in the fields of land census, crop yield estimation, environmental governance, meteorological early warning and forecasting, and comprehensive disaster prevention and mitigation, and can provide information services for national economic construction.
Although the official did not give the remote sensing No. 41 satellite, how big and heavy it is, but it can be loaded with such a long and thick fairing, I believe that the size and weight of the satellite must be not small.
The big rocket sending the big satellite also shows that this is a heavyweight launch activity!
There is no doubt that Party A's father is the Ministry of Agriculture and Rural Affairs.
Why do we launch agricultural satellites into the sky at every turn? Actually, there is a reason.
No way, everyone knows that we are a big agricultural country, and for 1.4 billion people, the sky is big and the food is the biggest.
Whoever doesn't let us eat well will be in a hurry, so agricultural satellites are our favorite, and they must be the biggest and the best.
The agricultural census satellite launched this time is mainly used to observe the hatching and growth of bud worms, and to make timely predictions of diseases and pests.
At the same time, cooperate with the plant protection department to take effective measures to reduce and reduce the possible harm and impact of insect pests on crops.
The Chinese love peace and will not launch any reconnaissance satellites, but just want to see how the crops are growing, and by the way, see if the White House lawn should be mowed.
Since the elongated configuration is adopted, it shows that the optical lens of the satellite has a very long focal length and high resolution.
In particular, new pests such as 21, 16, 35, and 37 should be observed more accurately and clearly.
Coupled with the Beidou navigation satellite, a specific positioning is directly sent to the head above, which should be eliminated soon.
All kinds of practice tells us that pests and diseases are everywhere, so we must strengthen monitoring and not relax in the slightest.
Oh, by the way, don't defecate outdoors in the future, or you'll even be photographed wearing most sizes of your pants.
In general, our satellite focuses on flying in the sky, swimming in the sea, and crawling on the ground.
Of course, there is a need, and it is okay to help see whose vegetables and fruits are there.
After all, we are a country with a large population, and only by consolidating agriculture can we ensure food security.
In fact, if you think about it, there is a certain reason for China's agriculture to increase its output every year, and sending more such satellites will be of great help to the people's crops.
As the saying goes, when you have food in your hands, you don't panic!
As for the launch, why launch such a large satellite?
The main reason is that due to the influence of domestic chip technology, the volume cannot be effectively reduced. Chips the size of American fingernails, chips with the same function, we need the size of a round table.
Besides, our rockets are actually fat, and their strength is not as great as everyone thinks.
Because we are using a deeply improved version of the folk two kicks, it is not the same grade as American fireworks at all.
Can't compare, really can't compare, you look at other people's fireworks, every time they bloom, it's amazing.
Netizens speculated
It is worth mentioning that the day before the launch of the Fat 5, we successfully launched a reusable horizontally landed spacecraft in Jiuquan with a Long March-2F carrier rocket, that is, the Shenlong unmanned space aircraft.
Aerospace aircraft, as the name suggests, is a new type of aircraft that can fly in space and in the atmosphere, and has both aerospace and aviation functions.
You may not know that this is the third launch of the dragon.
The first was launched in September 2020 and flew in space for more than a day. The second was launched on August 5, 2022, and flew in space for 276 days.
On the other hand, the United States urgently called off the launch of its X-37B aerospace plane, which is the most secretive of its own secrecy.
Based on the above information, some netizens who don't think it's a big deal to see the excitement speculate that the remote sensing satellite launched by Fat Five is estimated to be not simple.
Some people even say that the mirror surface of the remote sensing satellite is larger than the diameter of the American keyhole 12.
At present, the world's largest military spy satellite is the American Keyhole 12 (KH12), which has a mirror diameter of 3 meters.
Speaking of this keyhole, Trump previously uploaded a picture on the Internet, which is a keyhole reconnaissance of Iranian rocket launches.
After clicking through the keyhole, not only can you see the four lightning towers around the circular launch pad, but even the length and angle of the tower's shadow are very obvious.
Even the hollowed-out structure of the launch pad itself can be seen, and the facilities on the edge of the circular launch pad, written in Persian, are "the product of national empowerment".
One can imagine how terrible the clarity of this satellite is.
But ha, these are all speculations from netizens.
end
Finally, I have to reiterate that what we launched this time is an agricultural satellite, which is just an unprecedented super-large optical satellite.
After all, there are many pests that are very small, and of course they need to be larger!
In any case, the more agricultural satellites are launched into the sky, it means that next year is estimated to be another bumper harvest year, which is gratifying!
