Earth I (Blue Marble)

This true-color image shows North and South America as they would appear from space 35,000 km (22,000 miles) above the Earth. The image is a combination of data from two satellites. The Moderate Resolution Imaging Spectroradiometer (MODIS) instrument aboard NASA's terra.nasa.gov/ Terra satellite collected the land surface data over 16 days, while NOAA's Geostationary Operational Environmental Satellite (GOES) produced a snapshot of the Earth's clouds.
