Chinese Long March rocket collapses due to re-entry into Maldives

China’s Long March rocket stage has re-entered the Earth’s atmosphere over the Maldives in the Indian Ocean, China’s National Space Agency confirmed.

According to the China National Space Administration, the re-entry occurred at 0224 Coordinated Universal Time on Sunday or 10:24 pm EST on Saturday.

The US Space Force has not yet confirmed the re-entry of the 18-ton rocket stage.

Long March 5 (consisting of one core stage and four boosters) took off from Hainan Island, China, on April 29 in an unmanned Tengu module. This module contains what will be the residence of a permanent space station in China.

The rocket is set to continue 10 more missions to complete the station.

The Long March 5 rocket was essential to China’s short-term space ambitions, from the planned delivery of space station modules and crew to the launch of spacecraft on the Moon and Mars.

The Long March, launched last week, was the second 5B variant deployment since its first flight in May last year.

McDowell previously told Reuters that rocket debris could probably fall to land in densely populated areas, such as May 2020, when the first Long March 5B debris fell into Côte d’Ivoire, damaging several buildings. Said there was. No injuries have been reported.

Debris from Chinese rocket launches is not uncommon in China. In late April, officials in Shiyan City, Hubei Province, informed the people of the surrounding counties to prepare for evacuation, as some were expected to land in the area.

“Long March 5B re-entry is rare because during the launch, the first stage of the rocket reached orbital speed, rather than going down in range as is commonly practiced,” Aerospace Corporation said in a blog post. It was.

“The body of the empty rocket is now in an elliptical orbit around the Earth and is being dragged towards an uncontrolled re-entry.”

Long March 5

The Long March 5 rocket, also known as the Long March 5, is a heavyweight rocket made in China.

Named after the long march of the Red Army during the Chinese Civil War.

It is the third most powerful rocket in operation after the SpaceX Falcon Heavy and Delta IV Heavy.

height: 186.9 feet

stage: 2

Payload to LEO: £ 55,000

Total launch: 7

Launch site: Wenchang

The empty core stage has lost altitude since last week, but the rate of its orbital decay remains uncertain due to unpredictable atmospheric variables.

This is one of the largest space debris returning to Earth, and experts estimate its dry mass to be about 18-22 tonnes.

In 2020, debris from another Long March rocket fell into the village of Côte d’Ivoire, causing structural damage, but no injuries or deaths.

The core stage of the first Long March 5B, which returned to Earth last year, weighs nearly 20 tons, surpassing only fragments from the 2003 Columbia Space Shuttle, the 1991 Soviet Union Salyut 7 Space Station, and the 1979 NASA Skylab. There was.

The first image of the rocket in orbit was released by astronomers on Thursday, and the Italian-based virtual telescope project captured the technology.

According to researchers, the rocket was moving “very fast” when it flew 435 miles above the telescope of the Virtual Telescope Project on Wednesday evening.

Genre Kamashi, an astronomer of the virtual telescope project that took the image, said: In catching this huge piece. “

“This is another bright success and shows the amazing ability of robotic facilities to track these objects.”

Abandoned rocket stages usually re-enter the atmosphere, usually on the water, and never go into orbit shortly after takeoff.

Volodymyr Levykin of Skyrora, CEO of British rocket startup, said events like the collapse of Long March 5 “shouldn’t happen” and “before a disaster” to deal with this situation. Called for action.

“Currently, there are about 26,000 objects orbiting the planet and new constellations of satellites launched in fragments from 60 years of space missions,” he said.

Orbital vehicles such as Skyrolla’s space tags help you safely unorbit space debris or transport it to abandoned orbit.

“The ability to refire the engine multiple times allows the tugboat to complete several missions after deploying the initial payload.”

“By integrating them as part of the third stage of the rocket, the” Space Tag “orbital fleet was prepared to effectively deploy the vehicle as part of every launch and call it whenever needed. Can be created. “

He includes some form of space tag in all future launches, regardless of who is doing it, to make sure that “uncontrolled re-entry is a thing of the past.” Said it should be.

How many items are in orbit?

  • Rockets have been on the market since 1957: 5450
  • Number of satellites in orbit: 8950
  • Number still in space: 5000

“It not only helps the planet and eliminates the turmoil that orbits it, but it also protects critical infrastructure that cost decades to trillions of dollars to build. It’s instant. It can be effectively wiped out. ”

Last May, another Chinese rocket fell out of control in the Atlantic Ocean off West Africa.

The Communist newspaper, Global Times, said the “thin-skinned” aluminum alloy exterior of the stage could easily burn out in the atmosphere, pose a very distant risk to people.

The Long March 5B rocket put the main module of Tenna into orbit on April 29th. China plans 10 more launches to put additional parts of the space station into orbit over the next few years.

The stage, approximately 30 meters (100 feet) long, is one of the largest space debris to fall to Earth.

The 18-ton rocket that fell last May was the heaviest debris that fell out of control since the former Soviet Space Station Salyut 7 in 1991.

China’s first space station, Tiangong-1, crashed into the Pacific Ocean in 2016 after confirming that Beijing had lost control. In 2019, the space agency managed the dismantling of Tiangong-2, the second station in the atmosphere.

In March, fragments of the Falcon 9 rocket launched by US airline SpaceX fell to Earth on the Washington and Oregon coasts.

China strengthens plans to become a space superpower on Mars and Moon missions

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

They have already sent the first lander to explore the other side of the moon-sharing photos from the part of our closest 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, collecting and returning samples of lunar soil for the first time in 45 years.

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

Chang’e 6 is the first mission to explore Antarctica on the Moon and will be launched in 2023 or 2024.

According to Chinese space authorities, Chang’e 7 will study the surface, composition and space environment throughout the mission, and Chang’e 8 will focus on technical surface analysis.

China is also reportedly working to build a lunar base using 3D printing technology and send future crew missions to the surface.

Mission number 8 may lay the foundation for this as it strives to validate the technology assigned to the project.

CNSA, like the ISS crew, is also building an orbiting space station where Chinese astronauts will conduct scientific experiments.

The agency also launched a mission to Mars in the summer of 2020. Mars plans to 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. This generator sends energy back to Earth, making it the largest man-made object in orbit.

There are also many ambitious space science projects, such as satellites looking for signs of gravitational waves and earth observation spacecraft to monitor climate change.
