The successful launch mission unfolded in the nightfall, and the huge rocket spewed flames and quickly rushed into space. It sent the long-awaited remote sensing satellite No. 41 into space, and the satellite smoothly entered the predetermined orbit, adding new brilliance to China's space industry.
This year's first "Fat Five" rocket launches!It was the sixth launch since its birth, and its last launch was on November 24, 2020, more than three years after it sent the Chang'e-5 probe to the moon.
If you take a closer look at the "Fat Five" rocket launched this time, you will find that its shape seems to have become elongated. Actually, instead of getting thinner, it's getting taller, so it looks more slender.
This time the Long March 5 rocket is different from the past, this time it uses a newly developed thickened and lengthened fairing, with a diameter of 52 meters, the length increased to 185 meters, the height of the entire rocket has also increased to about 63 meters, surpassing the previous China's tallest Long March 7 rocket (different versions of the height is 53 607 meters), becoming the highest launch vehicle in service in Asia and even in the world.
With this launch, our space industry has once again made remarkable achievements. I believe that in the near future, we will see more wonderful space launch missions, bringing us more surprises and achievements!This time, our "Fat Five" rocket turned into a "tall man"!
The fairing has become longer and thicker, and the thickened and lengthened fairing must have hidden an oversized spacecraft. We suspect that the remote sensing satellite No. 41 on board must be very large. And in order to launch this satellite, we need to use the Long March 5, the largest rocket in our country at present. This means that the satellite is not only huge, but also quite heavy.
However, officials did not disclose the specific size and weight of the remote sensing 41 satellite. But according to the 18 it uses5 meters long, 5With a fairing with a diameter of 2 meters, we can speculate that the length of this satellite may be about 15 meters, and the diameter is also close to 5 meters.
The LM-5 has a near-Earth capacity of more than 25 tons, so if the satellite is in low-Earth orbit, it should also weigh around 25 tons. However, CCTV reported that the artificial satellite belongs to a high-orbit optical remote sensing satellite. Therefore, since it operates on a higher orbit, it should not weigh so much.
The large rocket pushing a behemoth indicates that this is a heavyweight launch event. CCTV News also revealed that the main functions of the remote sensing No. 41 satellite are used for land census, crop yield estimation, environmental management, meteorological early warning, and comprehensive disaster prevention and mitigation, and can provide important information services for national economic construction.
