With reference to the NISAR (NASA-ISRO Synthetic Aperture Radar) satellite, consider the following statements: I. NISAR carries both L-band and S-band radar payloads to enable imaging of Earth's surface through dense vegetation and soil layers. II. One of its objectives is to assist in early warning systems for floods, crop loss, and coastal erosion by collecting nearly 80 terabytes of data each day. III. NISAR’s polar orbit enables it to complete a global scan cycle in 12 days, covering a swath of 240 km per pass. How many of the above statements are correct?
