A Russian test of an anti-satellite missile that created a cloud of debris and endangered humans living aboard the International Space Station has reignited concerns over space junk.
Thanks to a sharp rise in the number of private companies capable of putting satellites in orbit at a greatly reduced cost, the number of objects in space has soared in recent years.
Private companies like Elon Musk’s SpaceX and Jeff Bezos’s Blue Origin are opening up a new era in space flight and small satellites, but experts have for years given warning of the perils of ignoring the problem of space junk before taking the next small steps into the cosmos.
What experts are saying about space junk
“Space junk rises to the level of our national consciousness only when something – an inactive satellite, busted-up rocket boosters, fragments of manned spacecraft – threatens us back on Earth,” US futurist Amy Webb wrote in 2018.
“Space junk is a problem that continues to orbit our collective attention, and within days it will once again circle out of view. We’ll ignore the problem to our own detriment.”
Russia’s missile test last week destroyed an old satellite in low Earth orbit and created a cloud of hundreds of thousands of pieces of debris, 1,500 of which are large enough to track from the ground, prompting US officials to accuse the Russians of “dangerous and irresponsible behaviour”.
After several officials at first denied that Russia was behind the test, Defence Minister Sergei Shoigu eventually defended the action and said the debris did “not pose any threat to space activity”.
But this view was not shared by space officials and experts.
Nasa administrator Bill Nelson said he was “outraged by this irresponsible and destabilising action. With its long and storied history in human spaceflight, it is unthinkable that Russia would endanger not only the American and international partner astronauts on the ISS but also their own cosmonauts.
“All nations have a responsibility to prevent the purposeful creation of space debris from Asats (anti-satellite weapons) and to foster a safe, sustainable space environment,” he said.
The crew of astronauts on board the International Space Station – including two Russian cosmonauts – were forced to take shelter in their re-entry capsules while they passed near the debris cloud, Nasa said.
The US space agency was already tracking more than 100 million pieces of space junk orbiting the Earth.
Even the smallest objects can pose a threat to fragile satellites and orbiting laboratories like the ISS because of the incredibly high speeds at which they are travelling – often in excess of 28,000kph.
Though the near-term threat posed by space junk is largely confined to satellites in low Earth orbit, experts want action now before any unforeseen consequences arise.
“As the number of rocket launches increases, the more space junk there will be – and it's unclear what the long-term effects on the atmosphere may be,” wrote Alice Gorman, a pioneering “space archaeologist”, whose research focuses on space debris.
“The quantity of human materials in orbit is only increasing more rapidly with the launch of "mega-constellations" of communication satellites, like Starlink, SpaceX's plan to provide low-cost satellite internet access,” she wrote.
Calls for better regulation
After the Russian Asat test, Pentagon spokesman John Kirby said the event showed the need for international regulation governing activity in space.
"We've been very clear, we would like to see norms for space so that it can be used responsibly by all spacefaring nations," he said.
While there are international agreements that govern the use of weapons in space – in 1963, the UN General Assembly unanimously adopted a resolution prohibiting the introduction of weapons of mass destruction in outer space – Asat tests such as the one carried out by Russia this week are not illegal.
After a similar Russian test destroyed a satellite in July last year, international space agencies and former astronauts signed an open letter from the Outer Space Institute, calling for a halt to Asat testing.
“The development of mega-constellations along with the expected growth of crewed space missions make debris-generating Asat tests significantly more perilous than before,” the letter said.
The institute said Asat tests could create a domino effect, leading to a cascading series of incidents and creating more and more orbital debris, similar to the disaster depicted in the 2013 film Gravity.
Regulation regarding space junk, the institute said, has “lapsed”.
But a host of space companies and organisations this week committed to redoubling their efforts to find ways of reducing the amount of junk in orbit by 2030.
The Net Zero Space charter, launched on November 12 during the Paris Peace Forum in France, was signed by high-profile space companies including Arianespace and Eutelsat.
“There are about 4,700 operational satellites currently in orbit, and this number could rise to more than 25,000 by the end of the decade," Arianespace chief executive Stephan Israel said.
“We must therefore urgently address the question of our responsibility in relation to the increased use of space, so we can safeguard the benefits for humanity over the long haul.”

What is graphene?
Graphene is a single layer of carbon atoms arranged like honeycomb.
It was discovered in 2004, when Russian-born Manchester scientists Andrei Geim and Kostya Novoselov were "playing about" with sticky tape and graphite - the material used as "lead" in pencils.
Placing the tape on the graphite and peeling it, they managed to rip off thin flakes of carbon. In the beginning they got flakes consisting of many layers of graphene. But as they repeated the process many times, the flakes got thinner.
By separating the graphite fragments repeatedly, they managed to create flakes that were just one atom thick. Their experiment had led to graphene being isolated for the very first time.
At the time, many believed it was impossible for such thin crystalline materials to be stable. But examined under a microscope, the material remained stable, and when tested was found to have incredible properties.
It is many times times stronger than steel, yet incredibly lightweight and flexible. It is electrically and thermally conductive but also transparent. The world's first 2D material, it is one million times thinner than the diameter of a single human hair.
But the 'sticky tape' method would not work on an industrial scale. Since then, scientists have been working on manufacturing graphene, to make use of its incredible properties.
In 2010, Geim and Novoselov were awarded the Nobel Prize for Physics. Their discovery meant physicists could study a new class of two-dimensional materials with unique properties.

Recharge as needed, says Mat Dryden: “We try to make it a rule that every two to three months, even if it’s for four days, we get away, get some time together, recharge, refresh.” The couple take an hour a day to check into their businesses and that’s it.
Stick to the schedule, says Mike Addo: “We have an entire wall known as ‘The Lab,’ covered with colour-coded Post-it notes dedicated to our joint weekly planner, content board, marketing strategy, trends, ideas and upcoming meetings.”
Be a team, suggests Addo: “When training together, you have to trust in each other’s abilities. Otherwise working out together very quickly becomes one person training the other.”
Pull your weight, says Thuymi Do: “To do what we do, there definitely can be no lazy member of the team.”

Dubai works towards better air quality by 2021
Dubai is on a mission to record good air quality for 90 per cent of the year – up from 86 per cent annually today – by 2021.
The municipality plans to have seven mobile air-monitoring stations by 2020 to capture more accurate data in hourly and daily trends of pollution.
These will be on the Palm Jumeirah, Al Qusais, Muhaisnah, Rashidiyah, Al Wasl, Al Quoz and Dubai Investment Park.
“It will allow real-time responding for emergency cases,” said Khaldoon Al Daraji, first environment safety officer at the municipality.
“We’re in a good position except for the cases that are out of our hands, such as sandstorms.
“Sandstorms are our main concern because the UAE is just a receiver.
“The hotspots are Iran, Saudi Arabia and southern Iraq, but we’re working hard with the region to reduce the cycle of sandstorm generation.”
Mr Al Daraji said monitoring as it stood covered 47 per cent of Dubai.
There are 12 fixed stations in the emirate, but Dubai also receives information from monitors belonging to other entities.
“There are 25 stations in total,” Mr Al Daraji said.
“We added new technology and equipment used for the first time for the detection of heavy metals.
“A hundred parameters can be detected but we want to expand it to make sure that the data captured can allow a baseline study in some areas to ensure they are well positioned.”

5 of the most-popular Airbnb locations in Dubai
Bobby Grudziecki, chief operating officer of Frank Porter, identifies the five most popular areas in Dubai for those looking to make the most out of their properties and the rates owners can secure:
• Dubai Marina
The Marina and Jumeirah Beach Residence are popular locations, says Mr Grudziecki, due to their closeness to the beach, restaurants and hotels.
Frank Porter’s average Airbnb rent:
One bedroom: Dh482 to Dh739
Two bedroom: Dh627 to Dh960
Three bedroom: Dh721 to Dh1,104
• Downtown
Within walking distance of the Dubai Mall, Burj Khalifa and the famous fountains, this location combines business and leisure. “Sure it’s for tourists,” says Mr Grudziecki. “Though Downtown [still caters to business people] because it’s close to Dubai International Financial Centre."
Frank Porter’s average Airbnb rent:
One bedroom: Dh497 to Dh772
Two bedroom: Dh646 to Dh1,003
Three bedroom: Dh743 to Dh1,154
• City Walk
The rising star of the Dubai property market, this area is lined with pristine sidewalks, boutiques and cafes and close to the new entertainment venue Coca Cola Arena. “Downtown and Marina are pretty much the same prices,” Mr Grudziecki says, “but City Walk is higher.”
Frank Porter’s average Airbnb rent:
One bedroom: Dh524 to Dh809
Two bedroom: Dh682 to Dh1,052
Three bedroom: Dh784 to Dh1,210
• Jumeirah Lake Towers
Dubai Marina’s little brother JLT resides on the other side of Sheikh Zayed road but is still close enough to beachside outlets and attractions. The big selling point for Airbnb renters, however, is that “it’s cheaper than Dubai Marina”, Mr Grudziecki says.
Frank Porter’s average Airbnb rent:
One bedroom: Dh422 to Dh629
Two bedroom: Dh549 to Dh818
Three bedroom: Dh631 to Dh941
• Palm Jumeirah
Palm Jumeirah's proximity to luxury resorts is attractive, especially for big families, says Mr Grudziecki, as Airbnb renters can secure competitive rates on one of the world’s most famous tourist destinations.
Frank Porter’s average Airbnb rent:
One bedroom: Dh503 to Dh770
Two bedroom: Dh654 to Dh1,002
Three bedroom: Dh752 to Dh1,152
