|Important EOS Satellites|
In 1967 NASA started its Earth Resource Technology Satellite program which resulted in the first Landsat satellite being launched in 1972, by far the biggest event in the history of Earth observing satellites. Since 1972, many other Earth observing satellites have been successfully launched. Some of these satellites are no longer operational, others are constantly acquiring data, while yet others are in planning to be launched in later years. This table summarizes the details of some of the most popular Earth observing satellites that are being used to study the land surface.

Scientists and interested observers can visually track the location of many satellites in near- real time with information from NASA's J-Track site. See also Heavens Above and Real Time Satellite Tracking.
