The Manned Space Flight Network (abbreviated MSFN , pronounced " misfin ") was a set of tracking stations built to support the American Mercury , Gemini , Apollo , and Skylab space programs.
71-661: There were two other NASA space communication networks at the time, the Spacecraft Tracking and Data Acquisition Network (STADAN) for tracking satellites in low Earth orbit, and the Deep Space Network (DSN) for tracking more distant uncrewed missions. After the end of Skylab, the MSFN and STADAN were merged to form the Spaceflight Tracking and Data Network (STDN). STDN was in turn replaced by
142-419: A backup role. Calculations showed, though, that a 26-m antenna pattern centered on the landed Lunar Module would suffer a 9-to-12 db loss at the lunar horizon, making tracking and data acquisition of the orbiting Command Service Module difficult, perhaps impossible. It made sense to use both the MSFN and DSN antennas simultaneously during the all-important lunar operations. JPL was naturally reluctant to compromise
213-409: A close flyby of Saturn 's moon Titan . The spacecraft sent back detailed images and data from both gas giants, revolutionizing our understanding of these distant worlds. The Voyager 2 spacecraft followed a more extensive trajectory, conducting flybys of not just Jupiter and Saturn, but also Uranus and Neptune. These encounters provided firsthand data from all four gas giants, offering insights into

In 1961, JPL hired Dana Ulery as the first female engineer to work alongside male engineers as part of
1775-596: The Moon , although primary responsibility remained with the Manned Space Flight Network (MSFN). The DSN designed the MSFN stations for lunar communication and provided a second antenna at each MSFN site (the MSFN sites were near the DSN sites for just this reason). Two antennas at each site were needed since the beam widths which the large antennas required were too small to encompass both the lunar orbiter and

Low Earth orbit missions, on the other hand, are only visible from a small fraction of the Earth's surface at a time, and the satellites move overhead quickly, which requires a large number of tracking stations, spread all over the world. The antennas required for LEO tracking and communication are not required to be as large as those used for deep space, but they must be able to track quickly. These differing requirements led NASA to build
