Q. With reference to Landsat-9, consider the following statements:
1. It is a joint mission by NASA and ISRO.
2. It will help identify water bodies affected by potentially harmful algal blooms.
Which of the statements given above is/are incorrect?
- Statement 1 is incorrect: The earth monitoring satellite, Landsat 9, is a joint mission of NASA and the US Geological Survey (USGS).
- Statement 2 is correct: If a forest is affected by drought, it will be seen in Landsat images and can help the researchers decode the areas at risk. Similarly during a wildfire, the Landsat images will capture the plumes of smoke and help study the extent of a burning. The satellite images can also help recovery experts plan sites for replanting. Landsat images can also help identify water bodies affected by potentially harmful algal blooms. According to NASA, scientists are now developing computer programs that would use Landsat and other satellite data to automatically warn lake recreation managers when blooms pop up.
