ESA’s Third Deep Space Ground Station To Be Built In Argentina

On 22 June, ESA informed Argentinean authorities that an area 30 km south of the town of Malarge in Mendoza province, about 1000 km west of Buenos Aires, has been chosen as the best option to build a new 35-meter antenna in support of its programs.

It is the first infrastructure to be built in Argentina by ESA.

"The site offers all the features that are required for a long-term ground segment investment. We are very pleased that we could pave the way for promising space missions with the support of the Argentinean authorities," said Gaele Winters, ESA Director of Operations and Infrastructure.

The decision, which is subject to successful completion of negotiations, is the result of several months of evaluation among 35 sites in both Chile and Argentina to establish ESA's third deep space ground station as part of the ESA Tracking (ESTRACK) network.

The Malarge site is situated in a desert area, free from radio interference and with frequency usage guaranteed in the longer term by Argentina's National Communications Commission.

ESA's deep space network currently has two 35-meter tracking stations, one in Cebreros, Spain, and the other in New Norcia, Australia. The third station in Argentina will join these and the seven other 15m stations forming the core ESTRACK network.

The 600-tonne dish will complete the 360-degree deep space coverage needed to ensure full telecommunications during mission-critical events and enhance the return of scientific data.

The antenna will become operational from mid-2012 in support of scientific and exploration missions. The finalization of the legal framework with Argentina is anticipated end-August 2009, so as to allow for approval by the ESA Council in October 2009.
