Criegee intermediates (CIs)—highly reactive species formed when ozone reacts with alkenes in the atmosphere—play a crucial role in generating hydroxyl radicals (the atmosphere's "cleansing agents") and aerosols that impact ...
A technique to cool the planet, in which particles are added to the atmosphere to reflect sunlight, would not require developing special aircraft but could be achieved using existing large planes, according to a new modeling ...
Through its "Moon to Mars" program, NASA plans to send the first crewed missions to Mars by the end of the next decade. To fulfill this bold vision, the agency is investigating advanced technologies through numerous programs. ...
As NASA prepares to return to the moon, studying astronaut health and safety is a top priority. Scientists monitor and analyze every part of the International Space Station crew's daily life—down to the air they breathe. ...
The accumulation of toxic elements poses a significant threat to terrestrial ecosystems, with the patterns and influencing factors of this accumulation being complex. However, elevational patterns of toxic elements in montane ...
In February, NASA's ER-2 science aircraft flew instruments designed to improve satellite data products and Earth science observations. From data collection to processing, satellite systems continue to advance, and NASA is ...

A research team led by Prof. Shi Chong from the Aerospace Information Research Institute (AIR) of the Chinese Academy of Sciences, in collaboration with Japanese scientists, has made a significant advancement in satellite-based ...
Prescribed burns literally fight fire with more fire. Often referred to as "beneficial fires," they target areas at risk for wildfires and burn away material that could otherwise fuel a future blaze.
The sun may rise every morning, but the amount of sunlight reaching Earth's surface can substantially vary over decades, according to a perspective article led by an international research team.
