Today, the Rosetta Mission is being tracked by five ground stations: ESA’s 35m dishes at Malargüe, Argentina, and New Norcia, Australia, and by NASA’s deep space network dishes DSS 14 (60 m, Goldstone, USA), 55 (34 m, Madrid, Spain) and 43 – this one is the 70 m antenna at Canberra, Australia, the largest steerable parabolic antenna in the Southern hemisphere!
