Debris of a launch vehicle with the Indian Space Research Organisation (ISRO) logo and the national emblem have reportedly been found recently in an uninhabited island in Maldives.

The debris of the Payload Fairing which are believed to be that of ISRO’s Launch Vehicle Mark-3 (LVM-3) washed up to an island near L. Kunahandhoo in Maldives, and found on February 12. Local Maldivian media have also reported on parts of the debris washing up to the shore.

The debris are said to have fallen on an uninhabited island and there has been no damage caused to any human life or property due to their impact.

indianspaceflight.in., a website which tracks Indian spaceflight and aerospace developments, in a post on X said the debris were likely from the LVM3-M6 mission.

“A PLF (Payload Fairing) has washed up on an uninhabited island near L. Kunahandhoo, #maldives (found February 12, 2026). The @isro logo’s position below the national emblem suggests it is likely from the LVM3-M6 launch. This follows a similar recovery on December 28, 2025, in Sri Lanka (Trincomalee), which also appeared to be from the same mission.  #ISRO #LVM3M6 #LVM,” @ispaceflight_in posted on X.

On December 19, 2025 ISRO launched the LVM3-M6 / BlueBird Block-2 Mission, a dedicated commercial mission onboard the LVM3 launch vehicle. During the mission, it successfully launched the BlueBird Block-2 communication satellite of AST SpaceMobile, U.S.A. and on November 2 the space agency used the LVM-3 to launch the CMS-03 communication satellite.

LVM3 is the heaviest rocket developed by ISRO and is a three-stage launch vehicle comprising two solid strap-on motors, a liquid core stage and a cryogenic upper stage .

ISRO is yet to confirm whether the debris are from an Indian launch vehicle.

China’s Shenzhou-20 crewed spacecraft has delayed its return mission to Earth after the vessel was possibly hit by tiny bits of space debris, the country’s human spaceflight agency said on Wednesday (November 5, 2025).

An impact analysis and risk assessment are underway, the China Manned Space Agency (CMSA) said in a statement, without providing any new schedule for the return mission, which was originally set to land in northern China on Wednesday (November 5).

The delay highlights the danger to space travel posed by increasing amounts of space debris. The debris, also called space junk, consists of discarded launch vehicles or parts of a spacecraft that float around in space hundreds of miles above the Earth, risking collisions with countries’ active space assets.

The Shenzhou programme takes Chinese astronauts to and from China’s space station, Tiangong, for six-month stays where they perform a variety of tasks, including repairing damage to the station caused by debris impact.

The Shenzhou-19 crew’s return mission in April was delayed by one day due to weather conditions at the landing site. But this is the first time that a return mission has been delayed by space debris.

Space junk a growing headache

The rapid increase in space junk in recent years has led to growing calls for cooperation on managing space traffic.

At a forum last year, Chinese President Xi Jinping called on Chinese and Arab countries to jointly build a “space debris observation centre”.

A United Nations panel on space traffic coordination said last year that urgent action was necessary, calling for a shared database of orbital objects as well as an international framework to track and manage them.

China in 2021 complained to the U.N. that Tiangong had to perform two emergency avoidance manoeuvres to avoid fragments produced by Starlink satellites, owned by Elon Musk’s SpaceX, which predominate in the Earth’s lower orbital paths.

Beijing and Washington have for years traded accusations of debris-creating behaviour.

“A certain superpower, being the first country to conduct anti-satellite weapon tests in outer space, has carried out more such tests and created more space debris than any other country,” China’s permanent mission to the UN wrote in a 2022 document, referring to the United States.

The U.S. called a Chinese anti-satellite missile test in 2007 “irresponsible” after it destroyed a satellite in polar orbit and created a massive debris field.

China has invested in technologies that could be used to reduce the risk of a space collision caused by debris.

This includes laser monitoring technology and deorbiting “sails”, which once unfolded can cause the attached spacecraft to speed up its descent into the Earth’s atmosphere, causing it to burn up without leaving space debris.

China’s Long March 6A rocket broke apart on August 6, creating nearly 300 debris pieces.

After accomplishing a noteworthy milestone of launching 18 Qianfan satellites, China’s Long March 6A rocket broke apart on August 6, producing almost 300 pieces of trackable debris in low Earth orbit.

The first wave of these satellites was supposed to form China’s “own version of Elon Musk’s Starlink,” the Qianfan (“Thousand Sails”) broadband network. The rocket was launched from the Taiyuan Satellite Launch Centre, located in the Shanxi Province of North China.

A report by The Wall Street Journal states that the breakup of the rocket generated a new concern over Beijing’s attitude towards space junk.

The report quoted LeoLabs, a US space-tracking firm, as saying the event might create at least 700 fragments floating some 500 miles above earth, making it one of the largest rocket breakups in history. Starlink said the debris didn’t pose significant immediate risks to its fleet, but the fragments are “likely to remain in space for decades due to the incident occurring at a high altitude.”

China and other countries are pressing ahead with plans to increase rocket launches, raising risks for humans and satellites in orbit. Yet there is little global policing of unsustainable practices.

“Who can enforce anything in space? It’s a bit like the Wild West at times,” Quentin Parker, director of the Laboratory for Space Research at the University of Hong Kong, told WSJ.

Darren McKnight, senior technical fellow at LeoLabs, said China’s recent record on generating debris related to Long March 6 launches was worrisome. “I hope it’s a wake-up call for them, and they’ll be part of the international dialogue,” he said.

A Chinese Foreign Ministry spokesman, Lin Jian, said last week that China “attaches great importance to space debris mitigation” and “has taken active efforts to fulfill relevant international obligations.” Without giving details, he said China took necessary measures after the recent rocket breakup.

It also said in the report that the Chinese activities in space are pointing toward a worrisome tendency in the direction of space junk. In 2022, a rocket stage from China had an uncontrolled re-entry into the Sulu Sea, wherein NASA criticised it for less-than-adequate data provision. Major pieces of junk have been created by Chinese rocket launches, including Long March 6A missions, which are notorious for their bad history. While other countries did better, Chinese behavior was largely responsible for space debris that affects low-Earth orbit environments.

China’s rocket broke apart creating 300 pieces of trackable debris in low Earth orbit (Representational)

New Delhi:

China’s Long March 6A rocket broke apart creating over 300 pieces of trackable debris in low Earth orbit, after achieving a significant milestone of launching 18 Qianfan satellites, the US Space Command (USSPACECOM) said today.

The 18 satellites were part of the first batch aimed to establish China’s “own version of Elon Musk’s Starlink”, called the Qianfan (“Thousand Sails”) broadband network.

The satellites were launched on Tuesday on the Long March 6A rocket from the Taiyuan Satellite Launch Center in North China’s Shanxi Province.

The satellites were designed and built by the Chinese Academy of Sciences’ Innovation Academy for Microsatellites in Shanghai.

While the rocket successfully delivered the satellites at an altitude of about 800 kilometres, soon after its upper stage broke apart. The breakup generated a cloud of debris that is trackable around Earth, the USSPACECOM said.

“USSPACECOM can confirm the breakup of a Long March 6A rocket launched on Aug. 6, 2024, resulting in over 300 pieces of trackable debris in low Earth orbit,” the organisation said in a statement, posted on social media platform X.com on Friday.

“USSPACECOM has observed no immediate threats and continues to conduct routine conjunction assessments to support the safety and sustainability of the space domain,” it added.

China launched the Qianfan mega constellation project in 2023 to provide more extensive and high-quality communication services for domestic users.

Developed by the Shanghai-based company SpaceSail, the Qianfan network is reported to establish a network of over 15,000 low earth orbit (LEO) wide-screen multimedia satellites in the long run, of which 108 satellites will be launched this year and 648 satellites by 2025 end.

By 2027, the constellation aims to provide global network coverage, and ultimately by 2030, encompass 15,000 satellites providing integrated services such as direct mobile connections, Global Times reported.

On the other hand, SpaceX’s Starlink currently has more than 6,000 satellites in space and has more than 3 million customers in 100 countries.

NASA has 6 months to respond to Mr Otero’s claims.

A US family whose home was hit by space debris earlier this year is seeking compensation from the American space agency NASA for property damage and mental anguish. The metallic cylinder slab punched a hole in the roof through two layers of ceiling in Alejandro Otero’s home in Naples in March. Back then, NASA said that the object was part of a 2.9-ton pallet of used batteries jettisoned from the International Space Station in March 2021. Mr Otero said his son was nearly injured by the impact. 

Now, law firm Cranfill Summer said in a press release that it filed a claim on behalf of Mr Otero and his family. It listed damages including non-insured property damage loss, business interruption, emotional/mental anguish and the costs for assistance from third parties. 

According to the BBC, Attorney Mica Nguyen Worthy said space debris “is a real serious issue because of the increase in space traffic in recent years”. “My clients are seeking adequate compensation to account for the stress and impact that this event had on their lives,” she added. 

Separately, speaking to CBS affiliate Wink-TV Mr Otero said that the space junk created a tremendous sound” as it blasted into his home. “I was shaking. I was completely in disbelief. What are the chances of something landing on my house with such force to cause so much damage,” Mr Otero said.

The US space agency confirmed that the debris was from its flight support equipment. It was a metal support used to hold old batteries on a disposal pallet jettisoned from the station in 2021. While most of the pallet was expected to burn up in the atmosphere, this particular piece survived the fiery re-entry.

 “The hardware was expected to fully burn up during entry through Earth’s atmosphere on March 8, 2024. However, a piece of hardware survived and impacted a home in Naples, Florida,” the agency said. The ISS will “perform a detailed investigation” on how the debris survived burn-up, according to Nasa. 

The BBC reported that the agency now has 6 months to respond to Mr Otero’s claims.

NASA confirmed it was part of a cargo pallet of used batteries that was released from space station.

Washington:

An American family is claiming more than $80,000 from NASA after a small piece of debris fell from space and smashed through the roof of their Florida home, a law firm said Friday.

The problem of space trash has risen in tandem with increased spatial traffic, and NASA’s response could set a precedent for how future claims are handled, law firm Cranfill Sumner said in a statement.

On March 8, the object weighing just 700 grams hit Alejandro Otero’s home in Naples, Florida, making a hole in the roof.

NASA later confirmed it was part of a cargo pallet of used batteries that was released from the International Space Station as waste in 2021.

Instead of fully disintegrating before falling to Earth, a section remained intact when it reentered the atmosphere, the US space agency said.

Otero’s son was at the house at the moment of impact, according to the law firm, which said that NASA has six months to respond to its claim.

“My clients are seeking adequate compensation to account for the stress and impact that this event had on their lives,” said lawyer Mica Nguyen Worthy.

“They are grateful that no one sustained physical injuries from this incident, but a ‘near miss’ situation such as this could have been catastrophic.

“There could have been serious injury or a fatality.”

NASA did not immediately respond to AFP’s request for a comment.

No injuries were reported in connection with the suspected piece of space junk.

A man in North Carolina was left astonished after he found a massive, mysterious object on a remote hiking trail. According to the New York Post, Justin Clontz, who is a groundskeeper at a luxury campsite, said he was “shocked” to find the massive object covered in dense metal sheets held together by unearthly-looking bolts.

The debris, which appeared to be covered in burnt carbon fibre, is at least 3 feet wide, about an inch thick, and stands at nearly 4 feet tall, according to the outlet. Though the object was burned, the surrounding area showed no signs of damage.

“It’s once in a lifetime you know, it doesn’t happen every day. We don’t know what it is. We just know that it’s not from up here,” Mr Clontz told a local TV station.

He explained, ”I just tied a rope to it and drugged it out with a lawn mower. It’s a one in a million chance that it lands especially if it landed somewhere off the trail in the woods you’d have never found it, but it just happened to land on the trail.”

Experts speculate the object could have fallen to earth from SpaceX’s Crew Dragon spacecraft, according to Space.com. Astronomer Jonathon McDowell added on X that the debris ”definitely looks consistent with being a bit of the Crew-7 Dragon’s trunk which reentered on a path right over this location on Tuesday.”

Notably, The Dragon spacecraft consists of two main parts: the capsule and the trunk. The trunk supports the spacecraft during ascent and carries unpressurized cargo. Typically, the trunk burns up in the atmosphere during reentry, but occasionally, parts can survive and fall back to Earth.

The owner of the campsite Glamping Collective said that they plan on reaching out to aerospace experts to figure out what exactly it is and where it came from.

”Space debris was not on our list of things we expected to be having conversations about. The only thing we’ve been able to come up with is that it’s some type of space debris that fell. It doesn’t look like anything off of an aeroplane,” said Matt Bare, owner of The Glamping Collective.

No injuries were reported in connection with the suspected piece of space junk.

ISRO’s ‘zero orbital debris’ milestone & the space debris crisis | Explained https://artifex.news/article68019524-ece/ Mon, 08 Apr 2024 06:50:09 +0000 https://artifex.news/article68019524-ece/ Read More “ISRO’s ‘zero orbital debris’ milestone & the space debris crisis | Explained” »

]]>

The story so far: The Indian Space Research Organisation (ISRO) has said its PSLV-C58/XPoSat mission has practically left zero debris in earth’s orbit. The space agency explained that the last stage of the Polar Satellite Launch vehicle (PSLV) used in the mission was transformed into a kind of orbital station — called the PSLV Orbital Experimental Module-3 (POEM-3) — before it was left to re-enter the earth’s atmosphere instead of floating in orbit once its mission was completed.

ISRO said that after it completed the primary mission of injecting all satellites into their target orbits, the fourth stage of the PSLV was transformed into the POEM-3. It was subsequently de-orbited from 650 kilometres to 350 kilometres, rendering it more susceptible to being pulled towards the earth and burning up in the atmosphere. ISRO also said it “passivated the stage,” meaning dumped its fuel, to avoid an explosion that could have flung small pieces of debris into orbit.

What is POEM?

Developed by the Vikram Sarabhai Space Centre (VSSC) as an inexpensive space platform, POEM uses the spent fourth stage of a PSLV rocket as an orbital platform. Used for the first time in the PSLV-C53 mission in June 2022, ISRO had POEM orbit the earth as a stabilised platform to perform in-orbit scientific experiments with various payloads.

POEM is powered by solar panels mounted on the fuel tank of the rocket’s fourth stage and a lithium-ion (Li-ion) battery. It has a dedicated navigation, guidance, and control (NGC) system to stabilise its altitude along with helium control thrusters. The NGC system has four Sun sensors, a magnetometer, and gyroscopes, and talks to ISRO’s NavIC satellite constellation for navigation. POEM also has a telecommand system to communicate with the ground station.

ISRO first demonstrated the reuse of the spent fourth stage of its rocket in its PSLV C-44 mission in 2019. After satellites were injected in the target orbits, the fourth stage, carrying a student payload called Kalamsat-V2, was moved to a higher circular orbit of 443 km and stayed there, allowing the payload to make observations.

What has POEM-3 achieved?

ISRO launched the PSLV C-58 mission from the Satish Dhawan Space Centre in Sriharikota on January 1, 2024. After deploying the XpoSat satellite in its desired orbit of 650 km, the fourth stage, now called POEM-3, was lowered to a 350-km high circular orbit. The lower a satellite is in orbit around the earth, the more drag it experiences and the more energy it needs to expend to stay in orbit.

POEM-3 featured nine payloads: two each from VSSC and Bellatrix Aerospace Pvt Ltd, one each from the start-ups TakeMe2Space, Inspecity Space Labs Pvt Ltd., Dhruva Space, and from LBS Institute of Technology, KJ Somaiya Institute of Technology, and ISRO’s Physics Research Laboratory, Ahmedabad.

POEM-3 completed 400 orbits around the earth by its 25th day. The payloads were operationalised to perform their experiments during this time. ARKA200, RUDRA, and LEAP-TD completed their respective experiments while the data from WeSAT, RSEM, and DEX were collected after every orbit for further analysis on the ground. Two fuel cells from VSSC demonstrated their ability to generate power. By January 27, 2024, all of POEM-3’s payload objectives were completed.

For two months, POEM-3 prepared for its re-entry while ISRO tracked it with its Telemetry, Tracking and Command Network (ISTRAC) stations in Bengaluru, Lucknow, Mauritius, Sriharikota, Port Blair, Thiruvananthapuram, Brunei, and Biak (Indonesia) and the Multi-Object Tracking Radar (MOTR) at Sriharikota. On March 21, POEM-3 reentered the earth’s atmosphere, meeting its fiery end.

Why is this significant?

With the rise in the number of satellites in orbit around the earth, space debris has become a pressing issue. Space debris in the low earth orbit (LEO) mainly comprises pieces of spacecraft, rockets, and defunct satellites, and the fragments of objects that have deteriorated explosively as a result of anti-satellite missile tests. This debris often flies around at high speeds of up to 27,000 kilometres per hour. Due to their sheer volume and momentum, they pose a risk to several space assets.

Millions of man-made debris and naturally occurring micrometeoroids orbit in and around Earth’s space environment at hypervelocity speeds averaging 10 km/s (22,000 mph)

Millions of man-made debris and naturally occurring micrometeoroids orbit in and around Earth’s space environment at hypervelocity speeds averaging 10 km/s (22,000 mph)

The LEO extends from 100 km above the earth’s surface up to 2000 km above. It includes satellites tracking intelligence data, encrypted communication, and navigation. According to ISRO’s Space Situational Assessment report 2022, the world placed 2,533 objects in space in 179 launches in 2022, up from 1860 objects in 135 launches in 2021.

Debris also exists, but in smaller volumes, in the geosynchronous orbit (GEO), which is 36,000 km above the earth’s surface. Currently, there are 7,000 operational satellites orbiting the earth at different altitudes along with millions of pieces of space debris. The U.S. Space Command tracks and catalogues space debris larger than 10 centimetres in LEO and larger than 0.3-1 metres in GEO.

In 2022, four on-orbit break-up events occurred, contributing to most of the debris created that year:

  1. March 2022: Intentional destruction of Russia’s Cosmos 1048 in an anti-satellite test adding 1408 fragments of debris
  2. July 2022: Break-up of the upper stage of Japanese H-2A while deploying GOSAT-2 satellite adding 52 fragments of debris
  3. November 2022: Accidental explosion of the upper stage of China’s Yunhai-3 adding 533 pieces of debris
  4. November 2022: Break up of the Japanese H-2A upper stage for the deployment of GCOM satellite adding 30 pieces of debris

The latest incident of space debris causing havoc was recorded on March 8 when a chunk of metal believed to be a discarded battery pallet from the International Space Station ripped through the roof and two stories of a house in Florida. The cylindrical piece, weighing almost 1 kilogram, was recorded by the US Space Command while re-entering the Earth’s atmosphere over the Gulf of Mexico, on a path towards south-west Florida at 2.29 PM that day. Five minutes later, the security camera of the house caught the sound of the metal crashing into it. NASA is still investigating the incident.

A major contributor to the rising number of satellites is American launch-services provider company Space X, which is currently also building a large constellation of 12,000 satellites to provide internet services worldwide. The project, named Starlink, has deployed satellites in 550 km, 540-570 km, and 335-345 km orbits and is expected to be completed by 2027. SpaceX has also applied for a second generation of Starlink satellites comprising 30,000 LEO satellites.

As more communication satellites/constellations are launched and more anti-satellite tests are conducted, more on-orbit breakup and collisions occur, producing smaller and smaller fragments in orbit. The number of space objects (debris or functional equipment) greater than 10 cm in size in LEO is expected to be about 60,000 by 2030, per ISRO estimates. Space debris also leads to two major risks – it creates unusable regions of the orbit due to excessive debris, and leads to the ‘Kessler syndrome’ – creation of more debris due to cascading collisions resulting from one collision.

How are space agencies dealing with debris?

Currently, there are no international space laws pertaining to LEO debris. However, most space-exploring nations abide by the Space Debris Mitigation Guidelines 2002 specified by the Inter-Agency Space Debris Coordination Committee (IADC), which the U.N. endorsed in 2007.

The guidelines outline methods to limit accidental collisions in orbit, break-ups during operations, intentional destruction, and post-mission break-ups. They also advise against the long-term presence of spacecraft and launch vehicle orbital stages in LEO and limit their interference in the GEO region.

NASA had instituted its Orbital Debris Program in 1979 to find ways to create less orbital debris and design equipment to track and remove existing debris. Currently, the sixth U.S. Armed forces wing, called the Space Force, tracks space debris and collisions in LEO. However, the agency has not implemented any technology to clean such debris yet; most such ideas are in the conceptual stage.

Similarly, the European Space Agency (ESA) has adopted a ‘Zero Debris charter,’ which includes multiple ways to mitigate space debris. It has also called for zero space debris by 2030 and seeks that other agencies adopt it as well.

On November 5, 2022, China was widely criticised when its rocket Long March 5B plunged into the Pacific Ocean after it broke up upon re-entry. Ranking among one of history’s most damaging break-ups, one of the more than 500 pieces left of the core stage was about 30 metres long and weighed between 17 and 23 tonnes.

Days later, China deployed a large spacecraft designed to de-orbit its defunct spacecraft. The device had a very slim ‘solar sail’ attached to the payload adapter, which when unfolded expanded to a 269 square foot sheet that would push defunct rocket parts towards the earth for faster re-entry

Japan also has a project, called the Commercial Removal of Debris Demonstration (CRD2), to tackle space junk. The Japan Aerospace Exploration Agency (JAXA) has partnered with private space company Astroscale to assess debris in phase I of the programme. In the second phase, JAXA will launch a satellite to approach the debris and rendezvous with it before capturing and removing it from orbit. Currently, JAXA is conducting tests of this craft.

Private companies in both Japan and China are also competing for debris clean-up contracts. Japan’s Astroscale is developing a method to refuel and repair satellites in space, allowing each de-orbiting mission to operate for longer. China’s Origin Space has launched a prototype robot capable of capturing debris with a large net.

India is working to mitigate space debris. Apart from the POEM missions, ISRO has set up a Space Situational Awareness Control Centre to protect its high-value assets from close approaches and collisions with inactive satellites, pieces of orbiting objects, and even near-earth asteroids. An Indian start-up named Manastu Space is working on technologies like in-space refuelling, de-orbiting of old satellites, and satellite life extension.

  • ISRO said that after it completed the primary mission of injecting all satellites into their target orbits, the fourth stage of the PSLV was transformed into the POEM-3.
  • POEM is powered by by solar panels mounted on the fuel tank of the rocket’s fourth stage and a lithium-ion (Li-ion) battery.
  • With the rise in the number of satellites in orbit around the earth, space debris has become a pressing issue.

Washington:

US authorities said they have issued a “breakthrough” first-ever fine over space debris, slapping a $150,000 penalty on a TV company that failed to properly dispose off a satellite.

On Monday the Federal Communications Commission (FCC) came down on Dish for “failure to properly deorbit” a satellite called EchoStar-7, in orbit since 2002.

“This marks a first in space debris enforcement by the Commission, which has stepped up its satellite policy efforts,” the FCC, which authorizes space-based telecom services, said in a statement.

As the geostationary satellite came to the end of its operational life, Dish had moved it to an altitude lower than the two parties had agreed on, where it “could pose orbital debris concerns,” the FCC said.

The commission said Dish, a US satellite television provider, pledged in 2012 to elevate the satellite to 300 kilometers (190 miles) above its operational arc.

But with fuel running low, it retired the satellite at an altitude just over 120 kilometers above the original arc.

“As satellite operations become more prevalent and the space economy accelerates, we must be certain that operators comply with their commitments,” said FCC enforcement bureau chief Loyaan Egal.

“This is a breakthrough settlement, making very clear the FCC has strong enforcement authority and capability to enforce its vitally important space debris rules.”

The FCC said the settlement “includes an admission of liability from the company and an agreement to adhere to a compliance plan and pay a penalty of $150,000.”

In a statement Tuesday, Dish appeared to counter the FCC over disposal requirements, and argued that the commission’s enforcement arm made “no specific findings that EchoStar-7 poses any orbital debris safety concerns.”

“As the Enforcement Bureau recognizes in the settlement, the EchoStar-7 satellite was an older spacecraft that had been explicitly exempted from the FCC’s rule requiring a minimum disposal orbit,” a Dish spokesperson said in a statement.

“DISH has a long track record of safely flying a large satellite fleet and takes seriously its responsibilities as an FCC licensee.”

Collision Risks

The US aviation regulator, FAA, recently announced its intention to reduce space debris by requiring private companies to dispose of the upper stages of rocket launch vehicles by, for example, returning them to the Earth’s atmosphere or moving them to a less congested “graveyard orbit.”

The new regulation, which has yet to be definitively adopted, already exists for government space missions.

“If left unchecked, the accumulation of orbital debris will increase the risk of collisions and clutter orbits used for human spaceflight and for satellites,” the Federal Aviation Administration said.

The European Space Agency estimates that around one million pieces of debris larger than a centimeter — big enough to “disable a spacecraft” — are in Earth’s orbit.

They are already causing problems, from a near-miss in January last year involving a Chinese satellite, to a five-millimetre hole knocked into a robotic arm on the International Space Station in 2021.

With satellites now crucial for GPS, broadband and banking data, collisions pose significant risks on Earth.
