The Antarctic ozone hole reached its annual peak size on Sept. 11, according to scientists from NASA and the National Oceanic and Atmospheric Administration (NOAA). The size of this year’s hole was 24.1 million square kilometers (9.3 million square miles) — an area roughly the size of North America.
A new satellite instrument suite is now sending back detailed information about the health of the Earth's ozone layer, the shield that protects the world’s population from harmful levels of the sun's ultraviolet radiation.
NASA said on Friday that its Upper Atmosphere Research Satellite (UARS) will most likely miss North America.
NASA said there is a 1-in-3,200 risk that a person who is minding their own business might find themselves being chased down by a defunct satellite the size of a tour bus traveling at 17,500-miles-per-hour.
A new NASA study of Earth's polar ozone layer reinforces scientists' understanding of how human-produced chlorine chemicals involved in the destruction of ozone interact with each other.
A NASA and university study of ozone and carbon monoxide pollution in Earth's atmosphere is providing unique insights into the sources of these pollutants and how they are transported around the world.
Despite near-record levels of chemical ozone destruction in the Arctic this winter, observations from NASA's Aura spacecraft showed that other atmospheric processes restored ozone amounts to near average and stopped high levels of harmful ultraviolet radiation from reaching Earth's surface.
Take a deep breath. On Earth the air is easy to take for granted. It's everywhere. But unlike just about every other career in the world, astronauts must bring their own atmosphere to work. It is this essential nature about the atmosphere that generated such high expectations for NASA's Aura satellite.
