The NISAR satellite mission is primarily related to which type of imaging?
Show answer & explanation
Correct answer: C
Explanation
Answer: Radar Imaging.
Explanation:
The NISAR (NASA-ISRO Synthetic Aperture Radar) satellite mission is primarily focused on radar imaging. It is a joint project between the American space agency (NASA) and the Indian Space Research Organisation (ISRO). This satellite utilizes 'Synthetic Aperture Radar' (SAR) technology, which is capable of capturing high-resolution images of the Earth's surface, even through clouds and in darkness. Its primary objective is to monitor subtle changes occurring on the Earth's surface (such as the melting of ice sheets, earthquakes, tsunamis, and landslides). This mission will provide unprecedented data for managing climate change and natural disasters on a global scale. It is the world's first satellite mission of its kind to utilize two distinct radar frequencies (L-band and S-band).
Additional Points:
Launch: It is scheduled to be launched using ISRO's GSLV Mk-II rocket.
Technical Feature: This satellite will be capable of mapping the entire Earth every 12 days.
