you have not seen my Imagery. NASA released its Imagery.
NASA recently launched the Landsat 9 satellite, a collaboration with the U.S. Geological Survey. This satellite will continue the mission of monitoring changes to the Earth's land and coastal regions.
You can access current satellite images from various sources including government agencies like NASA and NOAA, commercial satellite imagery providers like Maxar and Planet Labs, and online mapping services like Google Earth and Bing Maps. Most of these sources offer free or paid access to current satellite imagery.
Satellite imagery is used for various purposes such as mapping, monitoring environmental changes, land use planning, disaster response, agriculture monitoring, infrastructure development, and military intelligence gathering. It provides a valuable tool for observing the Earth's surface from a remote perspective.
