由月球上看地球,會是什麼景像?繞著月球運行的月神號太空船拍攝了這張新版的照片。它是兩個月前由日本所發射的月球探測任務 (月神號,Selenological and Engineering Explorer, 簡寫為 SELENE)科學計畫,暱稱為 Kaguya,它的主要目的是研究月球的起源與演化。上個月,月神號已抵達月球軌道,並開始傳輸資料和影像回地球。這張照片是由月神號上的 HDTV 所拍攝。由於月球永遠以同一面對著地球,因此月球上的太空人不可能看到地球東昇的景像。這張地球東昇的照片與40年前阿波羅8號所拍攝的地球東昇照片一樣,都只有在繞月的軌道上才辦得到。

What does the Earth look like from the Moon? A new version of this space age perspective was captured by the robotic Kaguya spacecraft currently in orbit around Earth’s Moon. Launched two months ago by Japan, the scientific mission of the Selenological and Engineering Explorer (SELENE), nicknamed Kaguya, is to study the origin and evolution of the Moon. Last month Kaguya reached lunar orbit and starting transmitting data and images. This frame is from Kaguya’s onboard HDTV camera. An astronaut standing on the lunar surface would never actually see the Earth rise, since the Moon always keeps the same side toward the Earth. This Earthrise as well as the famous Earthrise captured 40 years ago by the crew of Apollo 8, only occurs for observers in lunar orbit.
