Consider the following statement about NISAR:

1. It is a microwave remote sensing satellite for Earth observation

2. It is a joint mission of India and the USA.

3. Its full form is NASA-ISRO Synthetic Aperture Radar

4. It is targeted for launch onboard India’s GSLV

Which of the statements given above is/are correct?

Correct option is D

The correct answer is (d) All are correct

Explanation:

1.  NISAR (NASA-ISRO Synthetic Aperture Radar) is designed to observe Earth's surface using dual-frequency synthetic aperture radar (SAR) operating in L-band and S-band, which are part of the microwave spectrum. This allows for detailed Earth observation regardless of weather conditions.

2.  NISAR is a collaborative mission between NASA (USA) and ISRO (India), combining expertise and resources from both space agencies.

3.  The acronym NISAR stands for NASA-ISRO Synthetic Aperture Radar.

4.  NISAR is scheduled to be launched aboard India's Geosynchronous Satellite Launch Vehicle (GSLV) Mk II from the Satish Dhawan Space Centre.
