What is the full form of HysIS - an earth observation satellite developed by ISRO?
A
Hyper Solar Imaging Satellite
B
Hyper Sensitive Imaging Satellite
C
Hyper Spectrum Image sensing Satellite
D
Hyper Spectral Imaging Satellite
Explanation: 

Detailed explanation-1: -PSLV-C43 lifted off at 0957 hrs (IST) on November 29, 2018 from the First Launch Pad (FLP) of Satish Dhawan Space Centre SHAR, Sriharikota and successfully launched India’s Hyper spectral Imaging Satellite (HysIS) and 30 international co-passenger satellites.

Detailed explanation-2: -HysIS, the primary satellite of PSLV-C43 mission, weighing about 380 kg, is an earth observation satellite configured around ISRO’s Mini Satellite-2 (IMS-2) bus. The primary goal of HysIS is to study the earth’s surface in the visible, near infrared and shortwave infrared regions of the electromagnetic spectrum.

Detailed explanation-3: -The Anand Nano satellite will demonstrate the capabilities and commercial applications of miniaturized earth-observation cameras for earth observation using a microsatellite in Low Earth Orbit. Astrocast, a 3U spacecraft, is a technology demonstrator satellite for the Internet of Things (IoT) as the payload.

Detailed explanation-4: -EO-1 (NASA) In 2000, NASA launched the EO-1 satellite which carried the hyperspectral sensor “Hyperion”. Hyperion produced 30-meter resolution images in 242 spectral bands. Hyperion really kicked off the start of hyperspectral imaging from space.
