On 1 April 2026, ESA brought its fourth deep space antenna into full operations at New Norcia in Western Australia. DSA 4<\/a> gives Europe a significantly stronger grip on spacecraft venturing to the furthest reaches of the Solar System.<\/p>\n

The 35-metre dish is ESA\u2019s third deep space antenna in the southern hemisphere. It joins existing dishes at the same Australian site and in Malarg\u00fce, Argentina, along with a counterpart in Cebreros, Spain \u2014 all part of ESA\u2019s Estrack ground station network.<\/p>\n

From First Signal to Full Operations<\/p>\n

Engineers inaugurated the antenna on 4th October 2025, then spent months calibrating dish mechanics, radio frequency stages, power systems and timing equipment. On 1st April, the team tracked Euclid<\/a>, ESA\u2019s dark matter telescope, as the antenna\u2019s first operational contact.<\/p>\n

\u201cAfter so much testing, experiencing the moments when the antenna finally goes online is very rewarding,\u201d said Harald Ernst, a New Norcia station engineer who worked with DSA 4 teams from before commissioning began.<\/p>\n

Cooling to Near Absolute Zero to Catch Whispers From Space<\/p>\n

DSA 4\u2019s engineers built the system around one central problem: the further a spacecraft travels, the fainter its signal becomes. To tackle this, the antenna chills its receivers to minus 263 degrees Celsius using cryogenic technology. At that temperature, background electrical noise drops sharply, so the system detects transmissions that would otherwise vanish entirely.<\/p>\n

A 20-kilowatt radio transmitter handles the outbound side. That output roughly matches the power a small car draws while accelerating onto a motorway. Because radio signals weaken with distance, much like ripples spreading across water, that level of power ensures commands reach spacecraft clearly, even across billions of kilometres. DSA 4 also supports downlink in X-, K- and Ka-band, with K-band uplink capability to follow.<\/p>\n

Two Dishes, One Virtual Giant<\/p>\n

Two 35-metre antennas at New Norcia now unlock a significant bonus. Together, they can function as a single, larger virtual dish, boosting sensitivity to faint signals beyond what either achieves alone. Additionally, if one antenna needs maintenance, the other keeps coverage intact. ESA\u2019s Network Operations Centre in Darmstadt runs all Estrack stations remotely, around the clock.<\/p>\n

DSA 5 Already in Planning<\/p>\n

ESA member states approved funding for a fifth 35-metre antenna at the November 2025 Ministerial Council. So while DSA 4 opens a new chapter, Europe\u2019s ground infrastructure is already looking beyond it.<\/p>\n
