Earth from Space
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 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.

The European Space Agency ( ESA ) ( French : l' Agence spatiale européenne - ASE ; German : Europäische Weltraumorganisation ) is an intergovernmental organisation dedicated to the exploration of space , currently with 20 member states. Established in 1975 and headquartered in Paris, France , ESA has a staff of more than 2,000 with an annual budget of about €4.02 billion / US$5.38 billion (2012). [ 1 ] ESA's space flight program includes human spaceflight, mainly through the participation in the International Space Station program , the launch and operations of unmanned exploration missions to other planets and the Moon, Earth observation, science, telecommunication as well as maintaining a major spaceport , the Guiana Space Centre at Kourou , French Guiana , and designing launch vehicles. The main European launch vehicle Ariane 5 is operated through Arianespace with ESA sharing in the costs of launching and further developing this launch vehicle.
