Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Name the NASA’s instrument on its Earth Observing-1 (EO-1) that helped them to measure methane emissions from a single, specific leaking facility on Earth’s surface
A
Mongoose-V microprocessor
B
Hyperion spectrometer
C
Lockheed L-1011
D
Beacon Monitor
Explanation: 

Detailed explanation-1: -The three primary instruments on the EO-1 spacecraft are the Advanced Land Imager (ALI), the Hyperion, and the Linear Etalon Imaging Spectrometer Array (LEISA) Atmospheric Corrector (LAC).

Detailed explanation-2: -Methane Source Finder (MSF) is a data system developed by NASA’s Jet Propulsion Laboratory which streamlines the visualization of airborne methane remote sensing data products. The MSF portal allows public access to the data collected during these airborne surveys, and view the surrounding source.

Detailed explanation-3: -Methane absorbs infrared light in a unique pattern – called a spectral fingerprint – that EMIT’s imaging spectrometer can discern with high accuracy and precision. The instrument can also measure carbon dioxide.

Detailed explanation-4: -SuperCam Measures the Air Scientists can learn about how atmospheric molecules, water ice, and dust absorb or reflect solar radiation.
