NASA’s Deep Space Network Achieves Milestone: All Antennas Combined for Voyager 1 Data

In a groundbreaking achievement, NASA’s Deep Space Network (DSN) successfully synchronized all six radio frequency antennas at the Madrid Deep Space Communication Complex on April 20, 2024, to receive data from the agency’s Voyager 1 spacecraft simultaneously.

The collaboration of all six antennas, a process known as arraying, significantly enhances the DSN’s capability to capture extremely faint signals from distant spacecraft. Voyager 1, currently positioned over 15 billion miles (24 billion kilometers) away from Earth, transmits signals that are exceptionally weak. To overcome this challenge, a large antenna or an array of multiple smaller antennas is employed. Presently, a five-antenna array is necessary to downlink scientific data from Voyager 1’s Plasma Wave System (PWS) instrument. However, as Voyager 1 continues to venture deeper into space, six antennas will be required to maintain communication. The distance Voyager 1’s signal covers to reach Earth currently stands at over 22 ½ hours, underscoring the significance of these technological advancements in maintaining communication with distant spacecraft.
