In the wee early morning hours of Tuesday (Nov. 16), the seven-person team of the International Space Station (ISS) woke up in alarm. A Russian missile test had simply blasted a decommissioned Cosmos spy satellite into more than 1,500 pieces of space debris– a few of which were close adequate to the ISS to necessitate emergency crash preparations.The four Americans, one German and 2 Russian cosmonauts aboard the station were informed to shelter in the transportation pills that brought them to the ISS, while the station gone by the particles cloud several times over the following hours, according to NASA.Ultimately, Tuesday ended with no noted damage or injury aboard the ISS, however the crews safety measures– and the NASA administrators stern reaction to Russia– were far from an overreaction. Area debris like the kind developed in the Kosmos break-up can take a trip at more than 17,500 miles per hour (28,000 km/h), NASA states– and even a scrap of metal the size of a pea can end up being a potentially lethal rocket in low-Earth orbit. (For contrast, a normal bullet released from an AR-15 rifle takes a trip at simply over 2,200 mph, or 3,500 km/h).

(Image credit: Numerica Corporation)”It doesnt take a huge hole to basically take off the space station,” John Crassidis, a SUNY Distinguished Professor at the University at Buffalo in New York who works with NASA to keep an eye on space debris, informed Live Science. Certainly, a hole measuring simply 0.5 inches (1.3 centimeters) wide could trigger irreparable structural damage that could completely “erase the area station,” Crassidis said.This is a substantial issue as the quantity of orbital particles– or “area junk”– around Earth has actually grown at a rapid rate over the past 60 years, Crassidis stated. NASA presently tracks more than 27,000 pieces of orbital debris that measure bigger than a softball, and uses computer models to estimate the positions of countless smaller sized pieces of scrap that are too small to be seen.If a piece of area particles has anything greater than a 1 in 10,000 chance of hitting a passing satellite or spacecraft, NASA employs avoidance maneuvers to physically move the jeopardized craft out of harms way, Crassidis said. This is a difficult balancing act, he added, as moving a satellite out of the course of one piece of particles might inadvertently send it into the path of a various piece of particles– such is the scale of the mess up there.Since 1999, the ISS has changed course 25 times to prevent known particles. To protect the station from smaller sized, unidentified pieces of clutter, the craft is covered in more than 100 impact guards called Whipple Shields, which work as “sacrificial bumpers” to take inbound hits instead of the ISS wall, according to NASA.Multiple damages and dings on the ISS exterior show that the station has actually been hit with particles before; in June 2021, a piece of particles even plowed a hole into one of the stations robotic arms– a metal device with a diameter of simply 14 inches (35 cm). Thankfully, it inflicted extremely little damage and the arm resumed operations immediately.However, where the ISS itself is well secured from inbound projectiles, the astronauts who crew and keep it are not– and that is where the greatest threat lies. According to Crassidis, even an encounter with the smallest piece of orbital debris could quickly eliminate an astronaut dealing with the outside of the ISS during a space-walk.”Space fits are not safeguarded at all,” Crassidis said. “Imagine a marble going 17,000 miles per hour [27,000 km/h] at you– it would go right through you, like a bullet.”Unfortunately, Crassidis added, there are no international laws preventing nations from carrying out low-orbit rocket tests like the one Russia just did. He fears that it might take an astronaut getting seriously hurt or perhaps killed prior to the world takes the space scrap issue seriously.While the immediate risk to the ISS from Russias missile test has passed for now, the particles from the blast could stay a risk for years and even years to come, Tim Flohrer, head of the European Space Agencys (ESA) Space Debris Office, told Live Sciences sister website Space.com. Satellites will likely have to take avoidance actions to guide clear of the junk cloud, and the ISS continues to pass near it every 90 minutes.NASA will monitor the debris cloud as closely as possible. For the ISS to be seriously affected by a tiny, un-trackable piece of the satellite would be like winning an “unlucky lotto,” Crassidis stated– unlikely, but not impossible.Originally released on Live Science.
