This timeline of artificial satellites and space probes includes uncrewed spacecraft including technology demonstrators, observatories, lunar probes, and interplanetary probes. First satellites from each country are included. Not included are most Earth science satellites, commercial satellites or crewed missions.
First dedicated and first published Earth observation images from outer space, first published on March 25, 1947. [9][10][11][12] July 26, 1948. First prepared wide-angle panorama of Earth from outer space (the 1946 flight did already record a panorama swing). [citation needed] October 5, 1954. Aerobee AJ10-24.
The first images from space were taken on the sub-orbital V-2 rocket flight launched by the US on October 24, 1946. Satellite image of Fortaleza.. Satellite images (also Earth observation imagery, spaceborne photography, or simply satellite photo) are images of Earth collected by imaging satellites operated by governments and businesses around the world.

List of USA satellites. This is a list of satellites and spacecraft which have been given USA designations by the United States Air Force. These designations have been applied to most United States military satellites since 1984, and replaced the earlier OPS designation. As of June 2022, USA designations have been assigned to 331 space satellites.
Vanguard 1 (Harvard designation: 1958-Beta 2, [3] COSPAR ID: 1948-002B[1]) is an American satellite that was the fourth artificial Earth-orbiting satellite to be successfully launched, following Sputnik 1, Sputnik 2, and Explorer 1. It was launched 17 March 1958. Vanguard 1 was the first satellite to have solar electric power. [4]
Vanguard 1. United States. 17 March 1958. U.S. Naval Research Laboratory. Oldest artificial satellite in orbit, along with its upper stage. Explorer 3. United States. 26 March 1958.
The concept of using orbital satellites to relay communications predated space travel, first being advanced by Arthur C. Clarke in 1945. Experiments using the moon as a passive reflecting way station for messages began as early as 1946. [ 3 ] With the launching of Sputnik 1, Earth's first artificial satellite, in 1957, interest quickly ...
