Planetary defense plans in progress.

It must be remembered that astronomers are very attentive to potentially dangerous asteroids, especially a new asteroid with an impact potential called 2013 DW, the impact probabilities are constantly recalculated, with each new data that arrives, with each new image, with each new analysis that is done and the normal thing is that the more data you have, the more the possibility of risk is reduced, is what usually happens normally. With the new data, there are fewer and fewer chances of impact, in fact, on March 8, the European Space Agency's Near-Earth Object Coordination Center has predicted an impact probability of 1 in 650, and it is possible that , in a few weeks with the new data and the new calculations, that possibility of impact will be further removed. The biggest space agencies like NASA, the European space agency, the Italian observatory, are looking up, as you can see, not only NASA is observing and monitoring potentially dangerous asteroids, there are many institutions, many astronomers, many countries, so no Only NASA has the monopoly on knowing what is happening in space, there are many voices involved that can provide a lot of data and alert us in the event of a real risk.

The question that many people ask is, if it would be worth reducing that risk margin to zero, completely eliminating the risk, not 1 in 625 or 1 in 6000 but 0, we could send a planetary defense mission, so here to the year 2046 there is a quite respectable time margin, the asteroid is also not far away, it is circling the sun close to the orbit of the earth, now it is about 18 million kilometers from us, which means that a mission could be sent quite Easy up to it and deflect it by crashing a ship into this asteroid. It can be done, as demonstrated by the NASA mission, on October 11, 2022, they managed to deflect the Dimorphos asteroid of about 160 meters in diameter, that is, it was much larger than this one, which is now potentially dangerous and not only NASA would be in willingness to be able to deflect the asteroid, china announced that it also has plans to deflect an asteroid, it would be the space rock or asteroid 2020 PN1, this is smaller, it is 40 meters in diameter, similar in size to the potentially dangerous asteroid that is now in the news .

The Chinese mission would be carried out from the year 2026 and would consist of launching a long March 3B rocket with a ship that would end up hitting the asteroid, so by February 14, 2046, the critical date, we could have at least two defense systems. planetary if the margin of risk increased. What do you think, it would be worth reducing the risk margin to zero or we trust the calculations and the possibilities, even if they are reduced from possible Impact.
