Mars is so dry because its water constant escapes into space. A new study suggests this process occurs in the ionosphere and faster than thought.

Multilayer plastic materials are ubiquitous in food and medical supply packaging, particularly since layering polymers can give those films specific properties, like heat resistance or oxygen and moisture control. But despite their utility, those ever-present plastics are impossible to recycle using conventional methods.

About 100 million tons of multilayer thermoplastics — each composed of as many as 12 layers of varying polymers — are produced globally every year. Forty percent of that total is waste from the manufacturing process itself, and because there has been no way to separate the polymers, almost all of that plastic ends up in landfills or incinerators.

Now, University of Wisconsin-Madison engineers have pioneered a method for reclaiming the polymers in these materials using solvents, a technique they’ve dubbed Solvent-Targeted Recovery and Precipitation (STRAP) processing. Their proof-of-concept is detailed today (November 20, 2020) in the journal Science Advances.

China plans to launch an unmanned spacecraft to the moon this week to bring back lunar rocks — the first attempt by any nation to retrieve samples from Earth’s natural satellite since the 1970s.

The Chang’e-5 probe, named after the ancient Chinese goddess of the moon, will seek to collect material that can help scientists understand more about the moon’s origins and formation. The mission will test China’s ability to remotely acquire samples from space, ahead of more complex missions.

If successful, the mission will make China only the third country to have retrieved lunar samples, following the United States and the Soviet Union decades ago.
