An out-of-control 21-ton Chinese rocket is falling to earth and could land on populated areas, experts warn.   

China’s Long March 5b rocket that launched Thursday is predicted to crash back to Earth within the next few days. 

Jonathan McDowell, an astronomer who tracks objects orbiting Earth, told SpaceNews that it’s path takes it ‘a little farther north than New York, Madrid, Beijing and as far south as southern Chile and Wellington, New Zealand‘. 

It could land anywhere in this range, that covers oceans and populated and unpopulated areas, but most of it would burn up in the atmosphere.   

Satellite trackers have detected the 100-foot-long rocket travelling at more than four miles per second.

China launched Long March 5B at 11:23 am local time on Thursday to deliver the first stage of its upcoming space station.

The module, named ‘Tianhe’, or ‘Harmony of the Heavens’, will become living quarters for three crew members once the massive structure is complete.

China aims to complete its Chinese Space Station, known as Tiangong (Heavenly Palace) by the end of 2022, state media reported, after several further modules are launched.

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

Analyzing the rockets orbit in space, experts have generated a predicted trajectory for when the core stage falls back to Earth. Pieces that survive the burn up in the atmosphere could land just north of New York, Madrid, Beijing or as far south as southern Chile and Wellington, New Zealand '.

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

China aims to become a major space power by 2030 to keep up with rivals, including the US, Russia and the European Space Agency, and create the most advanced space station orbiting Earth.  

Chinese Space Station modules 

Tianhe: Core module. Launched on April 29, 2021 

Wentian: Experiment module I.  Launch planned for 2022

– Mengtian: Experiment module II. Launch planned for 2022

– Xuntian: Space telescope module. Planned launch in 2024 to co-orbit with Chinese Space Station

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

The ISS is backed by five participating space agencies – NASA (US), Roscosmos (Russia), JAXA (Japan), ESA (Europe), and CSA (Canada) – but China was originally barred from participating by the US. 

However, the return of the rocket could put an end to China’s celebration if the vehicle lands in an inhabited area.

Space debris trackers observed it moving slowly and unpredictably to Earth over the past few days, and  reentry of the vehicle would be one of the largest uncontrolled descents on record.

Long March 5B is about 100 feet long and 16 feet wide and although more than 10 tons of space debris has been left in orbit for an uncontrolled reentry, McDowell said that ‘by current standards it’s unacceptable to let it reenter uncontrolled.’

China is aware of the potential uncontrolled descent, as Holger Krag, head of the Space Safety Program Office for the European Space Agency, told SpaceNews: ‘It is always difficult to assess the amount of surviving mass and number of fragments without knowing the design of the object, but a reasonable ‘rule-of-thumb’ is about 20-40% of the original dry mass.’

China previously launched Long March 5b in May 2020 (pictured) to test the vehicle in preparation of sending people to the moon, but this mission also ended with an uncontrolled reentry.

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

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

The force said it was notable not just for the size of the rocket but also the extent of the window of its uncontrolled descent.

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

Before it splashed down in the waters off the west coast of Mauritania the rocket core flew over Los Angeles and New York City.

CHINA STEPS UP PLANS TO BECOME SPACE SUPERPOWER WITH MARS AND MOON MISSIONS

Officials from the Chinese space agency are working to become a space superpower alongside the US and Russia.

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

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

This was done in collaboration with the European Space Agency who provided tracking information for the Chinese spaceship. 

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

Chang’e-7 will study the land surface, composition, space environment in an overall mission, according to the Chinese space authority, while Chang’e-8 will focus on technical surface analysis.

China is also reportedly working on building a lunar base using 3D printing technology and sending a future crewed mission to the surface.

Mission number eight will likely lay the groundwork for this as it strives to verify the technology earmarked for the project.

The CNSA is also building an Earth-orbiting space station where Chinese astronauts will conduct scientific experiments, similar to the crew of the ISS.

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

China is also said to be working on a project to build a solar power generator in space, that would beam energy back to Earth and becoming the largest man made object in orbit. 

They also have a number of ambitious space science projects including satellites to hunt for signs of gravitational waves and Earth observation spacecrafts to monitor climate change.
