From Satellites to Your Screen with EarthNow!
Adapted from USGS website

The EarthNow! image viewer (http://earthnow.usgs.gov) displays near real-time data from the Landsat 5 and Landsat 7 satellites as they pass over the United States. EarthNow! may be used by educators, scientists, or anyone with an interest in satellite imagery and the ways that satellite images show us changes in the Earth's surface.

When a Landsat satellite passes within range of the ground station at the USGS Center for Earth Resources Observation and Science (EROS), image data are down linked and displayed in near-real time. When no satellites are within range, the most recent pass is displayed.

The screen is divided into three sections:

  1. Moving window display: The main window shows image data for the current pass as it is received.
  2. Satellite location display: This section shows the location of the satellite providing the data. Shortly before a new live capture event is to begin, the map will show the location of the approaching satellite.
  3. Information area: This area shows the satellite that provided the data for the current pass, whether the pass is live or being replayed, and the time of acquisition. When a pass is being replayed, the next pass satellite and a countdown to when it will start is shown below the current pass information.

The site also provides help and FAQ pages, as well as links to more information about Landsat satellites.
