Missile fragment: Experts say China ‘neglected, irresponsible’

Experts questioned how China implemented its space program when the missile debris crash did not first occur.
Up to now, the possibility of the Truong Chinh 5B missile fragment falling into the dangerous residential area is assessed to be very low, but it is still possible.

The largest missile center in China is falling out of control in orbit, after it carried part of the new space station into space last week. The object is expected to fall to Earth during an “uncontrolled re-entry” on May 8 or 9. Whether it falls harmlessly into the ocean or affects the land where humans live, the reason the Chinese space program allows this to happen is – again – unclear. And given China’s planned launch schedule, it is entirely possible that such uncontrolled re-imports continue to occur. Missile Truong Chinh 5B in a launch in 2020.

However, the programs seem to continue to pose a small, though small danger to people across the planet without control of the path of the launched missile. Jonathan McDowell, an astrophysicist at the Center for Astrophysics in Cambridge, Massachusetts, who tracks objects in space, says: “I think it was their negligence. I think it is irresponsible. The uncontrolled drop is the reinforced core of Truong Chinh 5B, designed to lift large, heavy sections of the space station. For most rockets, the lower layers typically fall back to Earth shortly after launch. The upper layers, when they reach orbit, often reactivate the engine (after releasing the load), directing them to re-enter deserted areas such as the oceans. For the past three decades, only China has lifted layers of such large rockets into orbit and let them crash somewhere, said Dr. McDowell. “It is a technical decision based on possibilities.” He said that Chinese engineers were able to design the trajectory of the rocket so that it would remain in orbit, fall back to Earth shortly after launch, or they might have planned to activate the booster. fig to get it out of orbit in a non-dangerous way. Ted J. Muelhaupt, director of the Center for Orbital Research and Aerospace Debris re-entry, says: “The reintegration design cannot be taken lightly, it’s something the world as a whole has done because we need it.” As for Truong Chinh 5B reinforcement, it could be anywhere between 41.5 North latitude and 41.5 South latitude. That means Chicago, located further north, is safe, but big cities like New York could suffer. On May 6, Aerospace Corporation, a federally funded nonprofit that conducts research and analysis largely, predicts the re-entry will take place on May 8 at 11:43 p.m. Eastern time (10:43 p.m. 9/5 Vietnam time). If that is correct, the debris could fall to Northeast Africa, in Sudan. The timing uncertainty – a 16-hour fluctuation – and location are still large. A day ago, Aerospace predicted the re-entry site an hour in advance in the Eastern Indian Ocean. The calculations are complicated by many factors, for example, the sun. The increase in the intensity of the solar wind – charged particles sprayed by the sun – will inflate the Earth’s atmosphere, increasing its force on the object and increasing its rate of fall. The movement of the object also affects. The US Space Command and the Russian space agency are both monitoring the missile division. The Russian statement noted that the re-import will not “affect the territory of the Russian Federation” . The US agency meanwhile promised to update it regularly before the event was likely to take place. Currently the object is moving at a speed of about 29,868 km / h, so prediction of position also changes with each minute. China plans to launch several more launches in the coming months as the construction of its third space station is completed, known as the Heavenly Palace, or “palace in the sky”. That would require additional flights of giant rockets and the possibility of more uncontrolled re-imports leaving people on the ground anxious to follow, even when mishaps from single parts. very small. Jen Psaki, White House press secretary, said on May 5: “For the mutual benefit of all nations, it is necessary to act responsibly in space to ensure the safety, stability, security and long-term sustainability of space activities”. America hopes to push “Responsible spatial behavior”.
