space.com: One of the three antennas that make up NASA’s Deep Space Network is out of commission for an extra three months due to the failure of two bearings that allow the antenna to rotate. The problem was discovered when the antenna, based in Madrid, Spain, was taken out of service for routine maintenance. The DSN network collects data from the Mars Reconnaissance Orbiter (MRO), and the Cassini spacecraft which is orbiting Saturn.
