On January 26, according to the Russian satellite website, Musk launched a 4-ton Falcon 9 rocket in 2015, and its secondary wreckage floated in space for a long time due to fuel shortages and other problems. According to an international space tracking software, it is expected to hit the moon on March 4 this year.
In this regard, Musk feels that this is not a big deal, because even a collision will not have any impact. At the same time, the American astrophysicist Jonathan McDowell also said that the impact will not have a serious impact, and some space enthusiasts may be able to find new clues about the moon in this collision.
American climatologists also said that this impact can also observe the soil material deeper on the moon after the impact, which is not a bad thing. Fortunately, at that time, the mainland's Yutu-2 was still on the far side of the moon and would not be greatly affected.
While the impact on the moon isn't huge, this 4-ton "space junk" will leave an artificial crater on the moon, much to many people's disgust. McDowell said that similar incidents may have happened before, but we haven't found out yet.
However, this news still caused panic among many people. As we all know, Musk's SpaceX "Starlink" satellite project has always been a headache for countries, and he claims to eventually launch more than 30,000 satellites into low-Earth orbit to form a starlink network that covers the world's high-speed Internet. However, space experts have warned that the gradual increase in the number of satellites in low Earth orbit is likely to increase the risk of more out-of-control impacts.
We all know that space junk is really dominating low-Earth orbit now, causing the space station to have to make emergency avoidance five times. On January 26, at a webinar hosted by the Center for Strategic and International Studies, a U.S. think tank, researchers reported that the Mainland Practice 21 satellite "dragged" a failed Beidou satellite out of low Earth orbit, and has now separated from the failed Beidou satellite and returned again.
Simply put, the Continental Practice 21 satellite has achieved a new breakthrough, which can drag abandoned satellites and debris out of low-Earth orbit, equivalent to the "scavenger" of space. However, this matter has also been maliciously slandered by the United States, claiming that countries should be vigilant, and even demanding that the world should establish a transparent and standardized system to regulate the Chinese satellite.
Prior to this, mainland experts said that how to deal with space junk and scrapped satellites is a common problem that human beings need to face, and the mainland has also begun to make some attempts, which is conducive to the space environment and the well-being of mankind, which is not a bad thing.
