For nearly 20 years, models have predicted circulation changes in Titan's atmosphere, but thanks to Cassini's Composite Infrared Spectrometer (CIRS), built at Goddard, scientists have now observed this change directly.
In the aftermath of a massive storm on Saturn, data from the CIRS instrument on NASA's Cassini spacecraft reveal record-setting disturbances in the planet's upper atmosphere, including an unprecedented temperature change and a mysterious increase in the amount of ethylene.
Saturn's giant moon Titan hides inside a thick, smoggy atmosphere that cranks out methane and other hydrocarbons like a factory. New NASA-funded research estimates how long this chemical factory has been operating.
The Thermal Infrared Sensor (TIRS) that will fly on the Landsat Data Continuity Mission (LDCM) came out of its first round of thermal vacuum testing Tuesday, October 4. TIRS will be to help scientists and resource managers monitor water evaporation and transpiration on a field-by-field basis for agriculture.
