Fixing Pollution from Space Needs Global Coordination
Remote sensing is a tool of choice for monitoring regions for air pollution, but the scale of the problem requires extending geostationary soundings globally.

Certaines plantes laissent une empreinte digitale chimique sur un gaz qui appauvrit la couche d’ozone
Une nouvelle étude, la première dans son genre, suggère qu’il serait possible de recourir à une analyse isotopique pour localiser les sources et les puits de chlorométhane dans l’atmosphère.
Tiny Martian Moon May Be a Chip Off the Old Block
A close approach to Deimos reveals that its surface does not look like that of an asteroid, hinting at a Martian origin.
Plants Leave Chemical Fingerprints on an Ozone-Depleting Gas
A first-of-its-kind study suggests that isotope analysis could be used to pinpoint sources and sinks of atmospheric methyl chloride.
¿Podría la Vida Estar Flotando en las Nubes de Venus?
Si están presentes, los microbios podrían explicar patrones de evolución en la atmósfera planetaria de Venus, al observarse con luz ultravioleta.
Did Ozone Loss Cause the End Devonian Mass Extinction?
Ozone loss, perhaps as a consequence of a warming climate, may have been responsible for a catastrophic loss of biodiversity.
Solar Properties Rival for Control of Mars’s Bow Shock
While most planetary bow shocks are controlled by the solar wind, at Mars the solar EUV flux is equally important.
