Dust covered northern China earlier this week during some of the worst dust storms to hit the region in a decade.
The second annual Sun-Earth Day will "Celebrate the Equinox" on March 20 with programs and activities at NASA Centers and a two-hour televised webcast.
A NASA-facilitated Small Business Innovation Research (SBIR) partnership has resulted in a valuable service that may dramatically improve farming productivity and profitability.
A bloom of decaying algae with major ecological ramifications was recently observed by NASA's Multi-angle Imaging SpectroRadiometer instrument on the Terra satellite.
NASA and the German Center for Air and Space Flight successfully launched the Gravity Recovery and Climate Experiment, or "Grace," mission into Earth orbit at 1:21:27 a.m. Pacific time on March 17, 2002, from Russia's Plesetsk Cosmodrome. The mission, comprised of identical twin satellites, will precisely measure Earth's shifting water masses and map their effects on Earth's gravity field.
Wind data for the Pacific Ocean obtained by NASA's Quick Scatterometer spacecraft -- also know as Quikscat -- are documenting episodes of reversed trade winds that are responsible for unseasonable cyclone conditions in the northwest and southwest Pacific, and which may be a precursor of a future El Niño.
Thanks to recent NASA research, digital pictures taken from a remotely piloted, solar-powered airplane will help growers harvest better coffee and provide support during future natural disasters.
NASA and the German Space Agency are preparing to launch the Gravity Recovery and Climate Experiment (GRACE), a scientific pathfinder mission that will test a novel approach to tracking how water is transported and stored within the Earth's environment.
NASA researchers have found strong relationships between El Niño episodes and changes in climate and sea ice cover around Antarctica.
An 'ozone hole' could form over the North Pole after future major volcanic eruptions, according to the cover story by a NASA scientist in tomorrow's edition of the Proceedings of the National Academy of Sciences.
Data gleaned from studies of the 2001 hurricane season - with its unpredictable series of nontraditional storms - may hold a key to improved hurricane prediction and understanding, say scientists leading NASA's fourth Convection And Moisture Experiment (CAMEX) study.
