On:
In: Climate

The NASA Engineering and Safety Center (NESC) conducted a technical assessment to evaluate alternatives to dichloromethane, traditionally used for bonding transparent polymeric materials. This effort was initiated in response to potential regulatory restrictions under the EPA Toxic Substances Control Act (TSCA), which could impact critical bonding processes used in spaceflightContinue Reading

In: Climate

Melting ice from West Antarctica once delivered huge amounts of iron to the Southern Ocean, but algae growth did not increase as expected. Researchers found the iron was in a form that marine life could not easily use. This means more melting ice does not automatically boost carbon absorption. InContinue Reading
