According to media reports, during Russia’s Angara-A5 heavy rocket launch test on December 27 last year, the upper booster Persei failed to enter orbit (geostationary orbit). The booster was blocked by gravity or gravity. Pull back to the atmosphere again.
The U.S. Space Department reported that the relevant rocket debris fell into the South Pacific Ocean at 13:00 local time this Wednesday. Astronomer Jonathan McDowell, who works at the Center for Astrophysics at Harvard University, said on social platforms that everyone should not panic. He does not think it will. Brings great risks.
According to the report, although the take-off mass is about 20 tons, about 75% of the fuel will be consumed during the lift-off process. It is estimated that this uncontrolled “free-fall” booster is about 3.2 to 4 tons. It is not ruled out that some debris will fall to the ground. Experts still said that there is no need to worry too much.
The reason why Jonathan McDowell came forward to clarify is also related to the recently released satirical film “Don’t Look Up”, which tells the story of two astronomers who observed a comet about to hit the earth.
According to data, the Angara-A5 heavy rocket has undergone a total of three tests since 2014, and the first two successfully transported the virtual payload into orbit.
