“A one-centimetre fragment can destroy your spacecraft and it’s traveling so fast you don’t know it’s there from the ground. “The big problem in space is not big debris, but when big debris breaks up and becomes small debris,” Auburn said. The company’s managing director, John Auburn, said the real problem might not be the big pieces of debris that create the headlines and cause people back on ground to cast a nervous eye in the skies. The test is using a satellite to capture a test drone using a magnet in time, larger objects will require a robotic arm.
It’s a fiendishly difficult task, especially if the target satellite is spinning and tumbling. The discrepancy is accounted for by more than 560 “break-ups, explosions, collisions, or anomalous events resulting in fragmentation”.Īstroscale is currently demonstrating a vehicle called “ELSA-d” in lower Earth orbit to show that space debris clean-up is indeed possible. But the number of debris objects regularly tracked by Space Surveillance Networks stands at 28,160. The fate of Long March 5B could refocus governments and international bodies on the issue of space sustainability, and that could provide more opportunity to firms like UK-based Astroscale that are preparing to tackle the debris problem with commercial junk-collecting services.Īccording to the European Space Agency, about 6,900 of 11,370 satellites placed into Earth orbit are still circulating, with about 4,000 functioning. It fell on the Ivory Coast,” he said.Īn Ivorian gendarme takes notes next to debris that fell from space in the village of N’Guessankro near Bouake in central region in Ivory Coast on. The last one would probably fall in the ocean, except it didn’t. But probably is doing a lot of work here. China says it will probably fall in the ocean. “It’s my judgment that the Chinese are negligent. “There’s a lot of stuff being put into low Earth orbit, and some of it could possibly hit one another,” said Gabrynowicz.Īccording to Jonathan McDowell, an astrophysicist at the Harvard-Smithsonian Center for Astrophysics, China had every reason to know Long March 5B was unpredictable and would become uncontrollable. The European Space Agency hosted a major conference on the subject last month. When you have more actors and more stuff, it gets more complicated,” said Joanne Gabrynowicz a professor at the National Center for Remote Sensing, Air, and Space Law at the Mississippi Law Center.Įxperts have repeatedly voiced their worry about the risk of collisions since 2009, when two satellites – Iridium 33 and the derelict Russian military Kosmos-2251 –accidentally collided at 26,000mph over Siberia, shattering both in thousands of pieces. You don’t just have two space-faring nations – the Chinese are very significant, as is the European Space Agency, among others.
“Space debris has been known for a while, but now you have more competition in space. Previously, a piece of paint the size of a fingernail struck the windscreen of a space shuttle, piercing two of three layers of glass. Last month, mission controllers at SpaceX headquarters in California warned orbiting astronauts to put on their spacesuits and get back in their seats because a piece of space debris could strike the capsule. Under international treaty, private space actors, who are expected to put 45,000 satellites in low Earth orbit over the next several years, are under the legal responsibility of their host nations.Īdd to that, an estimated 9,300 tons of space junk that’s already orbiting the planet and the issue of space collisions and debris pollution is an issue of concern. Heavenly Harmony: China launches first module of new space station – videoīut the fiery fate of the booster, wherever it comes down, speaks to the larger issue of space debris and space sustainability, especially as space becomes a target not just for national space programs but also increasingly the private sector.
