From BBC World News  By Matt McGrath Environment correspondent, Edited by - Amal Udawatta IMAGE SOURCE, GETTY IMAGES A new way of sucking carbon dioxide from the air and storing it in the sea has been outlined by scientists. The authors say that this novel approach captures CO2 from the atmosphere up to three times more efficiently than current methods. The warming gas can be transformed into bicarbonate of soda and stored safely and cheaply in seawater. The new method could speed up the deployment of carbon removal technology, experts say. While the world has struggled to limit and reduce emissions of carbon dioxide in recent decades, several companies have instead focussed on developing technology to remove CO2 from the atmosphere.

  From - Sky & Telescope,  By Lauren Sgro   Edited by -Amal Udawatta This image, taken from 570 miles (920 kilometers) away shows the asteroid Didymos (bottom right) and its moonlet, Dimorphos, about 2.5 minutes before the impact of NASA’s DART spacecraft. NASA / Johns Hopkins APL Last year, NASA intentionally crashed the Double Asteroid Redirection Test (DART) into a nearby asteroid to test our ability to defend the Earth from rocky threats. The results are now in – the DART mission was a smashing success. On September 26, 2022,  DART hit its target asteroid Dimorphos , moon of the nearby asteroid 65803 Didymos, in a historic celestial experiment. Not only was DART the first planetary defense mission of its kind, but it marked the first time humanity was able to change the motion of a natural object in space. Initial estimations showed that  Dimorphos’ orbit shortened by 32 minutes  due to the impact, proving a successful deflection. Now, five papers published March 1st in  Nature

The Oxfordshire-based company wants to send up a sophisticated robot arm to grab hold of the dead hardware. This junk would then be sent downwards to burn up in the atmosphere. The UK government is running a competition to find the best solution to clear up historic debris. The winner will run demonstrate its technology in late 2026 or early 2027. The UK Space Agency is also looking at plans being developed by ClearSpace. This Swiss company, too, has a UK subsidiary that has received R&D funds from the agency. There's an ever-increasing amount of garbage in orbit - everything from old rocket segments to accidentally dropped astronaut tools, and even flecks of paint. And with thousands of satellites due to be launched in the next
