In the process of human exploration of space, a large amount of space junk will be generated.
According to British media reported on Wednesday, the Falcon 9 rocket launched by the US Space Exploration Technology Company (SpaceX) in February 2015, after completing the mission, its rocket debris is expected to crash into the moon in March this year, or become the first case, but it is believed that it will not constitute serious damage.
According to the report, the 4-metric-ton rocket wreckage will hit the moon at a speed of 2.58 kilometers per second. Meteorologist Eric Berger said the rocket did not have enough fuel to return to Earth's atmosphere and lacked the energy to escape the moon's gravity. Bill Gray, a data analyst who tracks near-Earth stars, said it could be the first case of a space junk accidentally hitting the moon, which could happen on March 4, but the time and location do need to be further observed.
However, the impact may provide valuable data, such as observing the subsurface material ejected from the moon when it is hit. Jonathan McDowell, a scholar at Harvard's Center for Astrophysics, agreed that the impact would occur on March 4, but said he wouldn't worry too much.
