CSIRO的帕克斯射电望远镜Murriyang在澳大利亚新南威尔士州拍摄的这张照片中指向了一个接近满月的地球。沐浴在月光下,这个64米长的天线正在接收来自奥德修斯的微弱无线电信号。2月22日,这个机器人着陆器在月球南极以北约300公里处着陆。奥德修斯号的登陆是1972年阿波罗17号登月任务以来美国首次登陆月球。奥德修斯在月球表面的倾斜方向阻止了它的高增益天线指向地球。但是,大型可操纵帕克斯天线的灵敏度大大提高了机器人月球着陆器向月球表面传递的实验数据的接收能力。当然,帕克斯射电望远镜在1969年阿波罗11号任务期间因其出色的月球电视接收能力而闻名,使地球上的居民能够观看第一次月球行走。

Murriyang, the CSIRO’s Parkes Radio Telescope, points toward a nearly Full Moon in this image from New South Wales, Australia, planet Earth. Bathed in moonlight, the 64 meter dish is receiving weak radio signals from Odysseus, following the robotic lander's February 22 touch down some 300 kilometers north of the Moon's south pole. The landing of Odysseus represents the first U.S. landing on the Moon since the Apollo 17 mission in 1972. Odysseus' tilted orientation on the lunar surface prevents its high-gain antenna from pointing toward Earth. But the sensitivity of the large, steerable Parkes dish significantly improved the reception of data from the experiments delivered to the lunar surface by the robotic moon lander. Of course the Parkes Radio Telescope dish became famous for its superior lunar television reception during the Apollo 11 mission in 1969, allowing denizens of planet Earth to watch the first moonwalk.
