NASA Eyes Effects of a Giant 'Brown Cloud' Worldwide
Date: 15 December 2004NASA scientists recently announced that a giant, smoggy atmospheric "brown cloud" that forms over South Asia and Indian Ocean has intercontinental reach, and has effects around the world.
Scientists studied the intercontinental smog or ozone processes associated with the "brown cloud" using a new NASA technique to combine data acquired by satellites with ozone data measured by instruments on special weather balloons. The brown cloud is a persistent, but moving, air mass characterized by a mixed-particle haze, typically brown in color. It also contains other pollution, such as ozone. Read more ...
NASA's Aura Satellite Sheds New Light on Air Quality and Ozone Hole
Date: 14 December 2004Launched in July of 2004, the EOS-Aura satellite research platform is already providing the first-ever daily, direct global measurements of low altitude or tropospheric ozone and many other pollutants that affect our air quality. Moreover, Aura delivers its results with unprecedented clarity over a region. The instruments onboard will help scientists monitor pollution production and transport around the world.
Measurements taken from the satellite also offer the potential for new insights into how climate changes influence the recovery of the stratospheric or upper ozone layer, the protective region that shields the Earth from ultra-violet radiation. Read more ...
Protecting our planet's ozone layer
Date: 3 October 2004Monitoring our planet's atmosphere has become an international priority. As successive world summits have stressed, our future on Earth could depend on safeguarding our environment. EuroNews 'Space' magazine reports today from the Royal Netherlands Meteorological Institute (KNMI) which is using instruments on several satellites to follow the evolution of ozone around the planet.

NASA Puts Safety First During Aura Launch
Date: 15 July 2004NASA engineers and mission officials decided during multiple launch attempts this week to postpone the launch of the Aura satellite to put safety first for mission success. Aura, a mission dedicated to the health of the Earth's atmosphere, launched successfully this morning at 6:01:59 EDT (3:01:59 PDT). Read more ...
Aura Launched, To Better Understand The Air We Breathe
Date: 15 July 2004Aura, a mission dedicated to the health of the Earth's atmosphere, was successfully launched today. This moment marks a tremendous achievement for the NASA family and our international partners. We look forward to the Aura satellite offering us historic insight into the tough issues of global air quality, ozone recovery and climate change, said NASA Associate Administrator for Earth Science Dr. Ghassem Asrar.

NASA Launch Advisory: Aura Launch Postponed
Date: 14 July 2004The launch of NASA's Aura spacecraft atop a Boeing Delta II rocket was scrubbed this morning due to an issue with one of the two batteries on the second stage of the Delta II launch vehicle. At approximately three minutes before the scheduled liftoff time, as the batteries were being transferred to internal power, the battery current level dropped below prescribed limits, triggering a launch hold.

NASA Plans to Put an Aura Around the Earth
Date: 3 June 2004Earth's atmosphere sustains life in all these ways, and by the thinnest margins. If a person could cruise at a speed of 60 miles an hour straight up, it would take just 6 minutes to exit the air we need to survive. Considering the relatively delicacy of this thin protective film, understanding our atmosphere goes hand in hand with protecting life as we know it.
On June 19, NASA will launch Aura, a next generation Earth-observing satellite that will make global observations of the ocean of air that surrounds our planet. Aura will supply the best information yet about the health of Earth's atmosphere. Read more ...
