Russian spacecraft for the Christmas


Here in the above topic, I mean as a surprise for Christmas. That is not like that. The Russian spacecraft launched on the 24th of December 2019. That is the day before Christmas. Now we can see most of the countries are involving this space science field. What is the reason for it?? It guesses the reason is curiosity. Do you agree with me?? The scientists were curious about the unknown things in the sky. This is my opinion. They are just trying to find objects in the far away. 

    Until the present, they have found many unknown things. But the scientists don’t think to stop this. And this will be a recurring habit of future generations too as well as that this field will improve in the future. That is with the new observations, new technologies, with powerful and intelligent minds and modern instruments. Now we can move to our topic today. Shall we??? 

 The Russian project 

      You know this is a Russian production. Not only that, actually it is Russia’s space agency Roscosmos production. The main goal of this spacecraft is observing the weather of the earth. 

   It is a satellite. This satellite is named as Electro – L 3. That was released to the orbit from the proton rocket. I think you remembered my previous article about the Russian spacecraft. Definitely, you have to remember. In that, I told you about a spacecraft that launched for the Russian military services. Then you think that the purpose of this is even for the military services. 

   No, that is incorrect. This is assigned to observe the weather changes in the earth. This is a geostationary ground-based satellite. Through this spacecraft, one portion of the earth can be covered. Then you are thinking about what is the specialty of knowing weather conditions. 

    Think for some time. Those reactions in the atmosphere can conclude about the rains, droughts, and floods. Therefore we follow safety precautions with the observations. Through that, the government and we can avoid the losses of human lives and the distraction of the properties. How important is that??? 

   This is the third weather observatory satellite. The first one was launched in 2011, and the second was launched in 2015. Alert that the third one is in 2019. Then we will see more about the proton rocket and the Electro – L 3. Shall we move to??? 

  Electro – L 3

   As in the above, this is the third satellite in the electro L series. The basic details are as follows. You know proton rocket released this satellite into space. That is the fifth launch of the Proton rocket within this year. Normally this is known as the weather rocket. At the time electro L 3 launched, the only functioning satellite is the electro L2. 

   This spacecraft has a mass of about 2094 kg while it has a payload mass of 2283 kg. The scientists have planned to keep this spacecraft about ten years in the orbit. The upper stage of this satellite is Block DM- 03. 

   The Early two satellites launched by the Zenit rocket. Therefore the third rocket even planned to release by the same. But later, that changed from the Zenit to proton rocket. Can you guess what the reason is??? That is because of the wake of Russia’s conflict with Ukraine. That is the reason for that. In the beginning, this satellite was planned to launch at the end of 2016 or at the beginning of 2017. Then it was postponed to the end of 2017. Then for 2018, after that, finally for 2019.

   The reason for such postpone is technical issues. After correcting all of that, it flew into space on the 24th of December 2019. On the 15th of August 2019, the Elektro L no. Three were shipped from the NPO Lavochkin. Before the launching of a spacecraft, there are some procedures that have to be done. There are tests to conduct. Some of them are the testing of the vacuum chamber and the electrical and the vibration tests. There are some other little tests are even for the launching. Some of them are like measurements of the clearness between the spacecraft and the launch vehicle and the launch vehicle fairing. Even the test deployment of the solar panels and antennas of the spacecraft worked grate. And the calculation of the spacecraft ‘s center of mass, mechanical loads measurements, and the tests for the propulsion system pressurization. 

   Before the launch, the spacecraft was rolled out to the pad on the 21st of December 2019. That is at the site 81 in Baikonur. After that, the electro L 3 satellite blasted off from the pad no. 24. That was on the 24th of December 2019 at the site 81 in Baikonur. 

   Then you can see the technical description of the spacecraft through the following. There are six engines. Those are RD 276 engines.  You have to know the procedure of lifting the vehicle. The first stage of the vehicle lifted the rocket off the pad and after a few seconds in vertical ascent. And after that, it started in the east for turning. Then it fired for around 2 minutes.

  After launching to space, it takes some time for the separation of the first stage. The firing of the lattice structure connects in the f two stages. And this is within the first few seconds. Before that, the four-engine cluster of the second stage took overpowered flight. That is about the first stage of this above spacecraft. Then we have to see the next part. 

   That is the second stage. The second stage worked for three and a half minutes. After that, it separated about 5 minutes and 35. 7 seconds. Then the four trusters of the steering engine fired through the special openings in the ring adapter. The steering engine is in the third engine. That is the second stage.

  Then we have another one. It is the third stage. This is firing its engine until 9.5 minutes. But the nozzle steering engine of the third stage operating for about 12 minutes. The satellite separated into a suborbital trajectory. That is with the block DM3 and the Electro L 3.

  As per the details, the payload section had separated from the third stage of the launch vehicle 585 seconds. Not only the payload section but also the upper stage and the satellites. Those above are the main and useful details about the launch of a Russian spacecraft. As I told above, scientists made this satellite to investigate the weather conditions. Therefore we can see the new details of that.
