	Thermal Vacuum Testing Thermal vacuum testing is the last major phase of the rigorous environmental testing that a spacecraft undergoes. During this phase, the spacecraft is exposed to alternate cycles of extreme heat and cold simulating the harsh environment of space. + More
	An Inside Look: The EOC Spacecraft subsystems and science instruments must be scheduled, controlled, and monitored daily. These operations are performed primarily at the EOS Operations Center (EOC), located at NASA's Goddard Spaceflight Center in Greenbelt, Maryland. + More
	Tropospheric Ozone Aura will make the first space-based comprehensive and near global ozone measurements in the lower atmosphere, mapping the sources and transport of aerosols and chemical pollution on regional and super-regional scales. + More
	Stratospheric Ozone Is the ozone layer changing as expected? Aura will measure the ozone and ozone-destroying radicals from nitrogen, hydrogen, and chlorine compounds to determine if the stratospheric ozone layer is recovering, as predicted by scientific model. + More
	Aura and Climate Change Aura will quantify and map the variability of ozone and water vapor, important "greenhouse gases" in the upper troposphere, and how aerosols either absorb or reflect radiation, in order to help us understand climate change. + More
	OMI Measures Volcanic Gas Cloud On May 20, 2006 a major lava dome collapse at the Soufriere Hills volcano triggered an explosive emission of volcanic gases. Sulfur dioxide in the resulting gas cloud was tracked by OMI for 3 weeks as it moved westwards across the Pacific. + More
	Asian Dust Storms Asia is suffering through the worst dust storm season in at least five years. The eighth major storm this year clogged the air over China, Korea, and Japan with sand from the Taklamkan and Gobi deserts. The sand picks up a toxic mix of heavy metals and carcinogens as the clouds pass over China's industrial areas, exacerbating health problems due to these storms. + More

The Microwave Limb Sounder Observes the Lower Stratosphere and Upper Troposphere
MLS observes the details of ozone chemistry by measuring many radicals, reservoirs, and source gases in chemical cycles which destroy ozone.

NO2 concentration over the United States from September 24, 2004 till November 7, 2004
This animation shows the daily presence of NO2 over the United States. Clouds obscure the Aura-OMI instrument from taking meaningful measurements so here the clouds are displayed in white. High levels of NO2 are shown in red.

Nitrogen Dioxide concentration over China from September 24, 2004 till November 7, 2004
This image is of Nitrogen Dioxide,NO2, on October 16, 2004. Nitrogen Dioxide concentration is clearly evident around Hong Kong, Shanghai, Bejing, Soul, and Osaka. Tokyo is covered in clouds so the Aura-OMI instrument can not measure the Nitrogen Dioxide concentration.

Aura/OMI Ozone Hole from September 12, 2004 to November 15,2004 with Polar Vortex Demarced
This animation shows layer blocking harmful UV radiation from the Earth's surface over Antarctica between September 12, 2004 and November 15, 2004.

Biomass Burning over South America
Biomass burning is the burning of living and dead vegetation. It includes the human-initiated burning of vegetation for land clearing and land-use change as well as natural, lightning-induced fires.
