To support the Apollo manned lunar-landing program NASA's Manned Space Flight Network (MSFN) installed extra 26 m antennas at Goldstone; Honeysuckle Creek, Australia; and Fresnedillas , Spain. However, during lunar operations spacecraft in two different locations needed to be tracked. Rather than duplicate the MSFN facilities for these few days of use, in this case the DSN tracked one while the MSFN tracked the other.
