NASA welcomes newest Deep Space Network comms dish

NASA Space Communications and Navigation’s Deep Space Network (DSN) has formally welcomed the latest node in an international network, with Deep Space Station 56 in Spain formally commencing operations.

Called Deep Space Station 56, or DSS-56, the dish is now online and ready to communicate with a variety of missions, including NASA’s Perseverance rover when it lands on the Red Planet next month.

The new 34-metre-wide dish has been under construction at the Madrid Deep Space Communications Complex in Spain since 2017. Existing antennas are limited in the frequency bands they can receive and transmit, often restricting them to communicating only with specific spacecraft.

DSS-56 is the first to use the Deep Space Network’s full range of communication frequencies as soon as it went online. This means DSS-56 is an “all-in-one” antenna that can communicate with all the missions that the DSN supports and can be used as a backup for any of the Madrid complex’s other antennas.


Badri Younes, deputy associate administrator and program manager of NASA's Space Communications and Navigation (SCaN), said, "DSS-56 offers the Deep Space Network additional real-time flexibility and reliability. This new asset symbolises and underscores our ongoing support for more than 30 deep space missions who count on our services to enable their success."

With the addition of DSS-56 and other 34-metre antennas to all three DSN complexes around the world, the network is preparing to play a critical role in ensuring communication and navigation support for upcoming moon and Mars missions and the crewed Artemis missions.

Thomas Zurbuchen, associate administrator of the Science Mission Directorate at NASA’s headquarters in Washington added, "The Deep Space Network is vital to so much of what we do – and to what we plan to do – throughout the solar system. It’s what connects us here on Earth to our distant robotic explorers, and, with the improvements that we’re making to the network, it connects us to the future as well, expanding our capabilities as we prepare human missions for the moon and beyond.

"This latest antenna was built as an international partnership and will ultimately benefit all of humanity as we continue to explore deep space."


With DSS-56’s increased flexibility came a more complex start-up phase, which included testing and calibration of a larger suite of systems, before the antenna could go online.

On Friday, 22 January, the international partners who oversaw the antenna’s construction attended a virtual ribbon-cutting event to officially mark the occasion – an event that had been delayed due to historic snowfall blanketing much of Spain.

Bradford Arnold, DSN project manager at NASA’s Jet Propulsion Laboratory in southern California, said, "After the lengthy process of commissioning, the DSN’s most capable 34-metre antenna is now talking with our spacecraft. Even though pandemic restrictions and the recent weather conditions in Spain have been significant challenges, the staff in Madrid persevered, and I am proud to welcome DSS-56 to the global DSN family."

In addition to Spain, the Deep Space Network has ground stations in California (Goldstone) and Australia (Canberra). This configuration allows mission controllers to communicate with spacecraft throughout the solar system at all times during Earth’s rotation.

The forerunner to the DSN was established in January 1958 when JPL was contracted by the US Army to deploy portable radio tracking stations in California, Nigeria, and Singapore to receive telemetry of the first successful US satellite, Explorer 1. Shortly after JPL was transferred to NASA on 3 December 1958, the newly-formed US civilian space program established the Deep Space Network to communicate with all deep space missions.

It has been in continuous operation since 1963 and remains the backbone of deep space communications for NASA and international missions, supporting historic events such as the Apollo moon landings and checking in on our interstellar explorers, Voyager 1 and 2.

The Deep Space Network is managed by JPL for SCaN, which is located at NASA’s headquarters within the Human Exploration and Operations Mission Directorate. The Madrid station is managed on NASA’s behalf by Spain’s national research organisation, Instituto Nacional de Técnica Aeroespacial (National Institute of Aerospace Technology).
