English: DSA 3 is the last of three 35-meter ESA's antennas designed for transmitting and receiving radio waves to and from the deep space (about two million kilometers from the Earth). DSA 1 is located in Australia, DSA 2 in Spain, while DSA 3 was constructed in an area 30 km south of the town of Malargüe in Mendoza province, Argentina. The three antennas are separated by about 120 degrees in longitude to ensure a continuous coverage of ESA's satellites and to compensate for the Earth's rotation.

Its technical facilities comprise Ka-band reception (31.8-32.3 GHz) and X-band transmission and reception.It is prepared to host Ka-band transmission (34.3-34.7 GHz) and K-band reception (25.5-27 GHz). The dish is 35 m in diameter and the entire structure is 40 m high; its moving antenna weighs 610 tonnes.
