NASA ends pioneer of the pollution sensor


LOS ANGELES, Feb. 13 (Xinhua) — The UNITED states National Aeronautics and Space Administration (NASA) at the end of the Tropospheric Emission Spectrometer’s (YOUR) nearly 14-year career of discovery on Jan. 31, the U.S. space agency said on Tuesday.

Launched in 2004, NASA’s Aura spacecraft, TES was the first instrument designed to monitor ozone in the lowest layers of the atmosphere directly from space.

The instrument has been scheduled for a five-year mission, but now, have escaped this term. It was originally designed to measure ozone in the troposphere. However, YOUR cast a wide public, capturing signatures of a wide range of other gases in the atmosphere, as well as ozone.

That flexibility has allowed the instrument to contribute to a wide range of studies, not only of the atmospheric chemistry and impacts of climate change, but studies of the cycles of water, nitrogen and carbon.

Its high-resolution observations have led to new measurements of gases in the atmosphere which have changed our understanding of the earth system, said NASA.

“te has been a pioneer, collecting a new set of measurements with the new techniques, which are now used by a new generation of instruments,” Kevin Bowman, the TES principal investigator of NASA’s Jet Propulsion Laboratory (JPL) was quoted as saying in a press release.

A mechanical arm on YOUR has started to stall intermittently in 2010, affecting the instrument’s ability to collect data continuously. The YOUR the team operations adapted by the use of the instrument in order to maximize science operations over time, try to extend the data series for as long as possible, according to NASA.

However, the blocking has increased to the point that YOUR lost operations approximately half of last year. The data gaps hindered the use of YOUR data for research, leading to NASA’s the decision of putting the machine out of service.

He will remain on the Aura satellite, receiving enough power to avoid the so cold that it can break and affect the other two instruments that work.

the New techniques developed for YOUR with wide applications throughout the System of the Earth to ensure that the mission’s legacy will continue long after YOUR’s the last goodbye, says NASA.
