Watch Goddard TV for the latest in NASA's research into Astrophysics, Earth Observing, and Solar Science. You may be surprised what you might find out!
One of the primary instruments on NASA's Aqua spacecraft is the Atmospheric Infrared Sounder (AIRS), which is providing a detailed three-dimensional view of the atmosphere. This new view is helping scientists to better understand the climate system and is proving of great value also in several practical applications, including weather forecasting.This video is public domain and can be downloaded at: http://svs.gsfc.nasa.gov/goto?10893Like our videos?

GPM Deputy Project Scientist Gail Skofronick-Jackson tells us about the science of falling snow and what the GPM mission will do to study this critical component of the Earth's water cycle.For the full story, go here http://www.nasa.gov/topics/earth/features/know-snow.html
A look at how the historic DaisyWorld model illustrates earth science concepts, such as albedo and feedback loops. This webshort was produced as an educational tie-in with the Science on a Sphere feature LOOP.

The Comet Nucleus Sample Return mission will collect subsurface samples from a comet and return them to Earth. Comets and asteroids are leftover remnants from the early solar system and by studying samples from these objects, we can learn more about the formation of our solar system and may find clues to the origin of life on Earth.This video is public domain and can be downloaded at: http://svs.gsfc.nasa.gov/goto?10813 Like our videos?

Tour the Cygnus X star factory. This video opens with wide optical and infrared images of the constellation Cygnus, then zooms into the Cygnus X region using radio, infrared and gamma-ray images. Fermi LAT shows that gamma rays fill cavities in the star-forming clouds. The emission occurs when fast-moving cosmic rays strike hot gas and starlight.This video is public domain and can be downloaded at: http://svs.gsfc.nasa.gov/goto?10878 Like our videos?

In three years, NASA's Fermi has detected more than 100 gamma-ray pulsars, but something new has appeared. Among a type of pulsar with ages typically numbering a billion years or more, Fermi has found one that appears to have been born only millions of years ago.A pulsar is a type of neutron star that emits electromagnetic energy at periodic intervals. A neutron star is the closest thing to a black hole that astronomers can observe directly, crushing half a million times more mass than Earth i...
Tractor beams -- the ability to trap and move objects using laser light -- are the stuff of science fiction, but a team of NASA scientists has won funding to study the concept for remotely capturing planetary or atmospheric particles and delivering them to a robotic rover or orbiting spacecraft for analysis. This animation shows how a hypothetical future mission might eventually employ tractor beam technology.This video is public domain and can be downloaded at: http://svs.gsfc.nasa.gov/goto?...
In October, 2011, NASA's Operation IceBridge discovered a major rift in the Pine Island Glacier in western Antarctica. This crack, which extends at least 18 miles and is 50 meters deep, could produce an iceberg more than 800 square kilometers in size. IceBridge scientists returned soon after to make the first-ever detailed airborne measurements of a major iceberg calving in progress.This video is public domain and can be downloaded at: http://svs.gsfc.nasa.gov/goto?10860 Like our videos?

The Thermal InfraRed Sensor (TIRS) is part of the Landsat Data Continuity Mission (LDCM) to continue thermal imaging and to support emerging applications such as evapotranspiration rate measurements for water management. TIRS is being built by NASA's Goddard Space Flight Center and has a three-year design life.TIRS completed its first round of thermal vacuum testing on Tuesday, October 4, marking the first time engineers evaluated the fully-assembled instrument at its normal operating temperat...
