Minuscule traces of metal from space junk that's designed to be disposable are invisibly polluting the Earth's atmosphere, a new study has found. In recent times, spacecrafts launched into space have been designed so that they fall out of orbit and fall back down to Earth after their intended use. So instead of the materials crashing on land, they can burn up in the upper atmosphere. Although the debris of rockets and satellites burn up when re-entering the planet's atmosphere, the consequences of metal vapour being left behind currently remain unknown. But given the amount of space exploration taking place, the amount of metal vapour is expected to rise in the years to come. Physicist Daniel Murphy of the National Oceanic and Atmospheric Administration (NOAA) has led a team of researchers to investigate what effects this metal vapour could have as well as its impact over time and this study was published in Proceedings of the National Academy of Sciences, as per Science Alert. He listed "iron, silicon, and magnesium from the natural meteoric source" as the current refractory material in stratospheric particular. Murphy has warned how this composition could be affected by the metal vapour from space junk. "However, the amount of material from the reentry of upper-stage rockets and satellites is projected to increase dramatically in the next 10 to 30 years," he wrote. "As a result, the amount of aluminum in stratospheric sulfuric acid particles is expected to become comparable to or even exceed the amount of meteoric iron, with unknown consequences for inclusions and ice nucleation." To find out if metal vapour remained, Murphy and his team took and analyzed 500,000 stratospheric aerosol droplet samples to see if they had traces of spacecraft metals. Aerosols contain sulfuric acid droplets made from the oxidation of the carbonyl sulfide gas and in the atmosphere, this can appear naturally or as a pollutant. Metal and silicon traces can be found in these droplets too, acquired from meteors which vaporize upon atmospheric entry. Around 20 metals were discovered from this research, and while some metals had similar ratios to the vaporizing meteors, other metals such as lithium, aluminium, copper, and lead exceeded the anticipated amounts. Particles from vaporized spacecraft were found in 10 per cent of stratospheric aerosols over a certain size while other common spacecraft metals such as niobium and hafnium were also present. Consequently, these traces of spacecraft particles could affect how water freezes into ice in the stratosphere, and stratospheric aerosol particles could change in size. Due to more space exploration planned in an "era of rapid growth" for the industry, the researchers predict "the percentage of stratospheric sulfuric acid particles that contain aluminum and other metals from satellite reentry will be comparable to the roughly 50 per cent that now contain meteoric metals."

Manuel Akanji admits Manchester City need to cut our the errors after being exposed in their comeback victory over RB Leipzig at the Etihad Stadium. The holders trailed 2-0 after a lacklustre first-half display in Tuesday’s Champions League encounter before a Phil Foden-inspired recovery saw them fight back to win 3-2. With their place in the last 16 already secure, there was little cause for alarm on the night but, after recent Premier League draws against Chelsea and Liverpool, the champions are not fully firing. Switzerland defender Akanji said: “We didn’t play well in the first half. We did a lot of mistakes, (in) a lot of duels. “We had it change it in the second half. We spoke in half-time that we needed to do better. It still wasn’t great but we improved a lot, we didn’t do many of the mistakes. “It happens sometimes. We didn’t plan to go into the game like this. The first goal was me losing a duel off the long ball, the second one was Ruben (Dias) after the pass and it happens sometimes. “Normally we don’t do these mistakes but the good thing is we’ve got a good team. “Now we have important games before the Club World Cup against Spurs and Villa and we need to really focus on these games. We need points because we drew twice so it’s really important to get winning again.” Akanji was indeed at fault for the first of Lois Openda’s two first-half goals, with Dias caught out for the second. Foden sparked the comeback when he teed up Erling Haaland to become fastest player to reach 40 Champions League goals in just his 35th appearance. The England midfielder then scored a sublime equaliser before showing further nimble footwork to set up the late winner for substitute Julian Alvarez. The victory ensures City, who travel to Red Star Belgrade next month, will finish top of Group G. With John Stones again not fit enough to feature, Akanji played in the defence-midfield hybrid role his colleague has excelled in. “I like it,” Akanji said. “I play wherever the manager puts me but also in the Chelsea game and the weekend against Liverpool I felt more comfortable in there because I got used to the position. “When you come from defence into midfield it’s a big difference because normally you have all the game in front of you and suddenly there are players coming from all angles. “But I got a better orientation with the game set-up so I felt more confident. I can adapt pretty good. I play in different positions. I try to listen and do what the manager wants from me.” Read More Will Zalatoris back in the swing after enduring ‘golfer’s worst nightmare’ John Turner aiming to push T20 World Cup hopes on England’s tour of Caribbean On this day in 2015: Great Britain end long wait for Davis Cup win First half was the worst I’ve seen us – Phil Foden savours thrilling fightback Rodrigo Bentancur set to be out until February after tearing an ankle ligament Jimmy Floyd Hasselbaink wants aspiring black managers to get ‘a fair chance’
