A large Chinese rocket is ready to launch into Earth at an uncontrolled re-entry after being launched from a space station.
The 21-tonne Long March 5B rocket launched a set of low-Earth orbits from China’s new space station last week.
But the 30-meter-long rocket also reached orbit, now making it one of the largest in history to make an uncontrolled comeback, according to Spacenews.com.
Experts say high-cost rockets will not reach speeds that will keep them in orbit, usually re-entering the atmosphere and landing in a known area.
Any debris that does not burn at the re-entry will land at sea or in an uninhabited area, but according to SpaceNews, “danger will cause damage to people or property”.
Last May, the first launch of Long March 5B also reached first phase orbit and had an unrestricted re-entry six days later.
The U.S. military said it had re-entered the Atlantic Ocean, but if it had happened 15 to 30 minutes earlier, the unburned debris would have reached U.S. soil.
According to space travel observer Jonathan McDowell, the size of the rocket is likely to return unprecedented.
“The focal point of Long March 5B is seven times larger than the second phase of Falcon 9, which caused a lot of press attention when it re-entered a few weeks ago. In Seattle And poured two pressure tanks into the state WashingtonHe said .SpaceNews.
“By current standards, I think it is unacceptable to be allowed to re-enter without restraint.
“Since 1990, more than 10 tons of unregulated re-entry have not been deliberately left in orbit.”
Materials that can be resold include components made from heat-resistant materials, such as steel or titanium tanks.
China aims to complete its Tiangang space station by 2022 following the introduction of the remaining blocks.
