China successfully launched the third and final piece of its new Tiangong space station on Monday – and the rocket’s 23-ton body is coming back down somewhere on Earth this weekend.
China’s Long March 5B rocket launched the Mengtian module. It carries science experiments. The rocket’s core stage gave the space station module one more push into Earth’s orbit as it was climbing into space. It then detach itself.
Contrary to most modern rocket bodies which push themselves into remote areas of the Pacific Ocean and other body types, the Long March 5B body found its own orbit around Earth.
It’s on track to descend into the atmosphere again – an event called “reentry” – and fall to Earth on Friday or in the morning Saturday in the Eastern time zone.
Nobody knows exactly where the rocket body is going to land and no one can control it. However, it is highly unlikely that any debris from outer space will strike you.
Forecast: It’s going rain rocket parts
Experts are unable to estimate how much of Long March’s rocket body (which is about the same size as a 10-story high building) will impact the Earth. While some of the rocket’s body will burn, it is not large enough to disintegrate completely.
According to experts from the Aerospace Corporation, 20-40% of large objects’ masses will survive the fall through the atmosphere. Insider previously.
It’s still too early to tell exactly where the core stage might fall – most likely in pieces. Aerospace Corporation tracks the rocket stage and predicts the possible routes it may take to Earth.
According to these analysts, approximately 88 per cent of the population is affected by debris. Calculations. However, this population is concentrated in a few areas. The vast majority of debris-prone areas are found in uninhabited or open ocean.
Space industry leaders still have their opinions. China’s uncontrolled reentry policy was condemnedIt poses an unacceptable risk to life and property.
As the rocket body nears reentry, estimates will rise.
China’s rocket waste keeps coming back to Earth
This is the fourth occasion that a fragment from China’s Long March 5B rocket threatened property and lives. Each of the three times the rocket launched – in 2020, 2021, and in July 2022 – chunks of its body fell back to Earth.
According to reports, one of the rockets’ debris was found near two villages in Ivory Coast in May 2020. Property damage. China claimed that remnants from the rocket had landed in the Indian Ocean close to the Maldives in 2021. The New York Times.
In July of this year, parts of the booster were removed from the rocket. Returned to Earth after being crashedWith several likely pieces discoveredOn the Malaysian side and the Indonesian side of Borneo Island, as well the area near the ocean. Philippines.
Most rocket stages can bring themselves down by restarting their engines soon after delivering their cargo into orbit. They do this to avoid populated areas, and steer themselves towards the Pacific Ocean. The Long March 5B rocket booster was not designed by China for controlled reentry.
John Logsdon (founder of George Washington University’s Space Policy Institute) said, “Rockets are launched all the time and very rarely is there concern about the reentry.” InsiderIn May 2021, while the world waited for a falling rocket body. “So yeah, this is happening.
Is it just a willful disregard for international guidelines? Or is it because the vehicle is new, it was not properly designed to allow for controlled reentry? Logsdon stated, “It’s all right.” He added, “It’s unfortunate that this puts a lot people at risk.”
This decade, space junk could be fatal to someone
In a StudyIn a July Nature article, researchers estimated that the chance of debris striking one or more individuals within 10 years was approximately 10%. This is not limited to Chinese rocket bodies. Spacecraft and unknown debris regularly fall from orbit.
Jonathan McDowell, an Harvard astronomer, said that “if you roll the dice too often, someone will get lucky.” He previously stated, “If I roll the dice too many time, someone will get Lucky.” Insider.
Ted Muelhaupt is a consultant for the Aerospace Corporation. Reentry databaseInsider was previously informed that an object of at least 1 Ton falls from orbit, and then reenters it’s atmosphere on a weekly basis.
Although the Long March 5B boosters are some of the most massive objects that have fallen back to Earth, uncontrolled reentry isn’t just a problem for China. NASA’s Skylab spacestation rapidly fell to Earth in 1979, scattering debris all over Australia. Controlled reentry is now a standard practice.
