The 21-ton Chinese rocket descends to Earth and can hit debris in populated areas



China’s 21-ton Long March 5b rocket orbits the planet in a way that could lead to a huge vehicle returning to Earth in the next few days, experts warn.

The main phase started on Thursday to deliver the country’s first modular module to the country’s new space station, but instead of returning to a pre-determined post in the ocean, an uncontrolled entry is expected – and possibly into a populated area.

Jonathan McDowell, an astronomer who tracks objects orbiting the Earth, told SpaceNews that the March 5 Long Road took him “a little north of New York, Madrid and Beijing and all the way south to southern Chile and Wellington.” New Zealand, and could land anywhere in that range.

When the rocket stage lands on Earth, most of it can burn up in the atmosphere, but large pieces can survive, which can lead to problems if the road takes Long March 5b to a settlement.

Satellite tracking devices also detected the main stage of the 5B long March with a length of 1

00 feet and a width of 16 feet, now referred to as “2021-035B”, moving at more than four miles per second.

China launches Long on March 5 at 11:23 a.m. Local time on Thursday to deliver the first phase of its upcoming space station.

The module, called “Tianhe” or “Harmony of Heaven”, will become a living space for three crew members once the massive structure is completed.

China is aiming to complete its Chinese space station known as Tiangong (Heavenly Palace) by the end of 2022, state media reported after launching several more modules.

When completed, the Tiangong Space Station will orbit the Earth at an altitude of 211 to 280 miles.

It is expected to have a mass between 180,000 and 220,000 pounds – approximately one fifth of the mass of the ISS, which is 925,335 pounds.

China seeks to become a major space power by 2030 to keep pace with competitors, including the United States, Russia and the European Space Agency, and to create the most modern space station orbiting the Earth.

Chinese space station modules

Tianhe: Main module. Launched on April 29, 2021

Ventian: Experimental module I. Launch planned for 2022

Mengtyan: Experimental module II. The launch is planned for 2022.

Xuntian: Space Telescope Module. Planned launch in 2024 for a joint orbit with the Chinese space station

The ISS, currently in orbit, took 10 years and more than 30 missions to assemble since the launch of the first module in 1998.

The ISS is supported by five participating space agencies – NASA (USA), Roscosmos (Russia), JAXA (Japan), ESA (Europe) and CSA (Canada), but China was initially banned from participating by the United States.

However, the return of the rocket could end the celebration of China if the vehicle lands in a populated area.

Tracking space debris has been watching him move slowly and unpredictably toward Earth over the past few days, and re-entering the car will be one of the largest uncontrolled descents in history.

The long March 5B is about 100 feet long and 16 feet wide, and although more than 10 tons of space debris have been left in orbit for uncontrolled re-entry, McDowell said it was “unacceptable by current standards to be allowed to re-enter uncontrolled.”

China is aware of the potential uncontrolled descent, as Holger Kragg, head of the European Space Agency’s Space Security Service, told SpaceNews: “It is always difficult to estimate the amount of surviving mass and the number of fragments without knowing the design of the site. but the reasonable “rule of thumb” is about 20-40% of the initial dry mass. “

Earlier, China launched Long on March 5, 2020 (pictured) to test the car in preparation for sending people to the moon, but this mission also ended with an uncontrolled re-entry.

The main stage of the Long March 5B rocket was sent into space on May 5 and fell to Earth a few days later, right off the coast of West Africa.

Its descent was confirmed by the 18th Space Squadron, a unit of the US Air Force that tracks space debris in Earth orbit.

The forces said they were noticeable not only by the size of the rocket, but also by the size of the window of its uncontrolled descent.

This uncontrolled descent left trackers guessing exactly where it would land – with speculation that it could be in the ocean or on land in Africa, the United States or Australia.

Before exploding in the waters off the west coast of Mauritania, the missile nucleus flew over Los Angeles and New York.

CHINA COUNTRIES PLANS TO BECOME A SPACE SUPERHOLOGIST WITH MARS AND LUNAR MISSIONS

Chinese space agency officials are working to become a space superpower along with the United States and Russia.

They have already sent the first descender to explore the far side of the moon – sharing photos from the part of our nearest neighbor that we rarely see as part of the Chang’e-4 mission.

In November 2020, they sent the Chang’e-5 spacecraft to the moon to collect and return the first samples of lunar soil in 45 years.

This was done in cooperation with the European Space Agency, which provided tracking information for the Chinese spacecraft.

Chang’e-6 will be the first mission to explore the moon’s south pole and is expected to launch in 2023 or 2024.

Chang’e-7 will study the earth’s surface, composition and space environment in a common mission, according to the Chinese space authority, while Chang’e-8 will focus on technical analysis of the surface.

It is also reported that China is working on building a lunar base using 3D printing technology and is sending a future crew mission to the surface.

Mission number eight is likely to lay the groundwork for this, as it seeks to verify the technology provided for the project.

CNSA is also building a near-Earth orbital space station where Chinese astronauts will conduct scientific experiments similar to the ISS crew.

The agency also launched a mission to Mars in the summer of 2020, which will see them land a rover on the surface of the red planet in February 2021.

It is also claimed that China is working on a project to build a solar energy generator in space that will radiate energy back to Earth and become the largest artificial object in orbit.

They also have a number of ambitious space science projects, including gravitational wave hunting satellites and Earth observation spacecraft to monitor climate change.
