A lovely picture from the Canberra DSN this morning, showing two of the workhorse 34-meter antennas communicating with the nearby GRAIL spacecraft. In the distance, the huge DSS-43 talks to the solar observatory STEREO-B.
Antennas of the Canberra DSN at work
Radio antennas in Australia track the twin GRAIL spacecraft on the way to the Moon. In the center is the 34-meter DSS-34 tracking GRAIL-A and at right is DSS-45 on GRAIL-B. In the left background, 70-meter DSS-43 is tracking STEREO-B.
