Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which institute set to launch Ice, Cloud Land Elevation satellite to track earth’s melting ice?
A
National Aeronautics and Space Administration (NASA)
B
Indian Institute of Technology (IIT)
C
Vikram Sarabhai Research Centre
D
Liquid Propulsion Systems Centre (LPSC)
Explanation: 

Detailed explanation-1: -The ICES at satellite (Ice, Cloud and land Elevation Satellite) was launched by the National Aeronautics and Space Administration of the United States (NASA) in 2003, and is currently the most important operational mission of a spatial LiDAR sensor.

Detailed explanation-2: -NASA to launch space laser to measure Earth’s polar ice: Here’s how.

Detailed explanation-3: -Later renamed, Landsat 1 became the first earth-observing satellite explicitly designed to study planet Earth. It contributed invaluable data and launched a revolution in remote sensing technology. Sources/Usage: Public Domain. The Landsat 1 (ERTS-1) Satellite.

Detailed explanation-4: -Launched September 15, 2018, ICESat-2 carries a photon-counting laser altimeter that allows scientists to measure the elevation of ice sheets, glaciers, sea ice and more - all in unprecedented detail. Our planet’s frozen and icy areas, called the cryosphere, are a key focus of NASA’s Earth science research.

Detailed explanation-5: -ICESat (Ice, Cloud,and land Elevation Satellite) is the benchmark Earth Observing System mission for measuring ice sheet mass balance, cloud and aerosol heights, as well as land topography and vegetation characteristics.
