As we all know, the United States has landed on the moon six times as early as fifty years ago, although so far, only 12 astronauts have stood on the moon, but the garbage created by humans has long been more than 200 tons!
It is conceivable that even if the astronauts have some non-essential items that they carry with them, or discard the cans containing urine, vomit bags and space boots when they are on them, the moon garbage is mainly upgraded and degraded to the lunar module left behind at the time of landing, as well as the spacecraft garbage of the non-manned lunar mission.
In other words, not all the garbage on the moon is "made in the United States", such as the Chang'e-5 probe we use to explore the moon, and it will also create some garbage on the moon because of this process. It's just that the United States is more special, because they directly declared the site of the moon landing that year as a historical site under their own protection, and no one can take away the objects and flags left by the astronauts from the landing place, of course, as of now, no second country has completed the manned lunar mission.
Soon, on March 4, the moon will see another rocket carcass, the Falcon 9 rocket launched by the United States. Many people may not know that the launch time of this rocket is actually many years ago, originally launched on February 11, 2015, the launch site is in an air force base in Florida, the United States, its main mission is to safely deliver the deep space climate observatory to Lagrange point 1, the mileage is about one million miles!
So, what is the great use of this deep-space climate observatory? You know, whether it's NASA or the National Oceanic and Atmospheric Administration, they all value this thing very much, because the smooth launch of this deep space climate observation can help them better study the Earth and space weather environment.
If there is no accident, after the Falcon 9 rocket was sent to the deep space climate observatory, its superior rocket would logically return to the Earth's atmosphere smoothly and then be directly burned into ashes, but the result was that the superior rocket that was supposed to return to the Earth was cruising in the Earth-Moon system for nearly 7 years, and when it hit the moon, it would have a full 7 years.
Of course, Falcon 9 is a very famous rocket, such an accident, at that time did cause a lot of sensation, as for the mission was not completed as originally planned, the researchers said that it is mainly because the upper layer and too high, so it led to insufficient fuel, and then the rocket superior can not return to the Earth's atmosphere, so it has been floating outside for so many years!
At present, American scientists have given the time when Falcon 9 is expected to hit the moon, that is, at 7:25 a.m. on March 4, 2022, of course, here is Greenwich Mean Time, if there is a time error, it is about one or two minutes, this is because the forecast time is based on simulation data, which may be slightly different from the actual situation.
The site of the impact on the moon is just the far side of the moon that we can't see on Earth, and the specific location is 233.20 degrees east longitude and 4.93 degrees north latitude. To know that the moon we usually see, no matter what time we see, is actually the front of the moon, including the 6 manned landings of the United States that year, although it is 6 different landing positions, but all are located on the front of the moon, so when our probe successfully soft landed on the far side of the moon, not only was there a probe landing on the far side of the moon, but also the first time that all mankind understood the far side of the moon so closely.
The moon is very important to the earth, like the tidal activity on the earth, in fact, is mainly affected by the gravitational pull of the moon, although the mass of the moon is far less than the sun, but its advantage is that it is very close! Therefore, when you see that the American Falcon 9 rocket is about to hit the moon, it will inevitably cause many people to worry, such as whether it will cause any bad impact on us living on the earth?
In fact, at present, American scientists have explained this problem, and directly said that the Falcon 9 impact on the moon is not a big deal, if anyone has the opportunity to see this impending impact process, it is a very interesting thing! In addition, for objects left in orbit such as Falcon 9, its own state cannot remain stable forever, and if it is not disturbed by the sun's orbit, it will hit the earth, or hit the moon.
In contrast, the effects of the impact on the Moon are negligible, as evidenced by the many spacecraft impacts that have occurred in the past. That is to say, the falcon 9 superior is not the first rocket body to hit the moon, and it is unlikely to be the last, including the Previous Apollo program of the United States, when the superior of multiple Saturn V rockets was actually directly led to the moon, so it seems that the garbage created by the United States on the moon is indeed a lot!
