The Navy was competed with the Army to put the first American satellite into orbit. Their first two Vanguard missions failed, with the second being a highly publicized failure, as it exploded on the launchpad. They went on to put 3 satellites into orbit but did not beat the Army to be the first. Their work in space continues today largely on military satellites.
Der ISS Tracker ermöglicht das Verfolgen der Trajektorie der Internationalen Raumstation (ISS) und anderer Satelliten.
Der Dienst nutzt Daten, die von Raumfahrtbehörden (TLE) bereitgestellt werden.
