<Anchor> Let's
summarize a little more with reporter Seo Dong-gyun, who watched the Nuri launch process
today (25th).

Q. Did the Minister of Transitional Affairs make an official announcement a little while ago?

[Reporter Seo Dong-gyun: First of all, it was announced that the launch of the Nuri was successful. It was news that seven satellites, including the 2nd small satellite, had successfully communicated. The first Toyosat has not yet been confirmed. In this case, it is not that the injection has not been carried out, but that it is in the blind spot of the so-called camera, so it needs to be checked a little more. In the initial communication, the satellite rotates when it is launched from the launch vehicle using a signal called a big con, so see if this rotation speed is well controlled. Make sure that equipment such as solar panels are working well. In the future, the satellite will go through the optimization process of the equipment for 7 months before carrying out a full-fledged mission, but in the case of the image radar, which is the main payload, the difficulty of the technology is high, and since it is the first localized equipment, it will go through the optimization process for about 1 year. Q

. The third launch of the Nuri was pleasantly successful, but what is the next task?

[Reporter Seo Dong-gyun: That's right. Apart from the Nuri upgrade project, we are looking further into space. We are trying to develop a next-generation launch vehicle not just a strong rocket, but a next-generation launch vehicle with a focus on economic feasibility such as reuse in line with the global trend. The fuel for rockets is called kerosene and carosine. We use the same kerosene fuel, but with a higher grade of kerosene that has been desulfurized, so that the fuel can be used efficiently. The combustion method will also be changed to be more efficient, increasing the possibility of reuse. We are also developing an engine that uses methane fuel, which is a fuel that is advantageous for reuse in the first place. ]

Seo Dong-gyun said, there is still a lot of work to be done. The universe is big, and there still seems to be plenty of open space for us.

First of all, let's hope that all the satellites that flew today will do their job.
