在這張來自地球上澳大利亞新南威爾士州的圖片中,澳大利亞聯邦科學與工業研究組織(CSIRO)的帕克斯射電望遠鏡(Parkes radio telescope)指向一輪近乎滿月的月亮。 2 月 22 日,機器人著陸器在月球南極以北約 300 公里處著陸, 64 米長的天線沐浴在月光下,接收到來自奧德修斯的微弱無線電訊號。奧德修斯號的著陸是自 1972 年阿波羅 17 號任務以來美國首次登陸月球。奧德修斯號在月球表面的傾斜方向使其高增益天線無法指向地球。但是,帕克斯大型可轉向碟形天線的靈敏度大大提高了機器人登月器對月球表面實驗資料的接收能力。當然,帕克斯射電望遠鏡碟形天線因其在 1969 年阿波羅 11 號任務中出色的月球電視接收能力而聞名於世,地球上的居民因此得以觀看到第一次月球漫步。
原文: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.
