在週日早上從澳大利亞愛麗絲泉的發射場進行期待已久的起飛後僅幾個小時,NASA 的南瓜形超長持續時間氣球 (ULDB) 就回到了地面。這個巨大的氣球(右圖)本應在兩週內環繞地球飛行,在地球表面上方約 22 英里的高度,大致沿著摩羯座熱帶線收集宇宙輻射資料。但在大約 85,000 英尺的高度,它發生洩漏,迫使科學家引導氣球及其 4,500 磅重的有效載荷返回地面。

洩漏原因仍在調查中,但據 NASA 官員稱,有效載荷垂直著陸,似乎狀況良好。“一個團隊正在審查飛行資料並檢查回收的氣球。預計在本週末之前會就 NASA 在愛麗絲泉可用的備用氣球的可能飛行提出建議,”NASA 氣球專案辦公室主任史蒂夫·史密斯 (Steve Smith) 說。“我們對 ULDB 概念以及為科學家提供研究地球和太空的新手段充滿信心。”

Kate Wong is an award-winning science writer and senior editor at 大眾科學 focused on evolution, ecology, anthropology, archaeology, paleontology and animal behavior. She is fascinated by human origins, which she has covered for more than 25 years. Recently she has become obsessed with birds. Her reporting has taken her to caves in France and Croatia that Neandertals once called home, to the shores of Kenya's Lake Turkana in search of the oldest stone tools in the world, to Madagascar on an expedition to unearth ancient mammals and dinosaurs, to the icy waters of Antarctica, where humpback whales feast on krill, and on a "Big Day" race around the state of Connecticut to find as many bird species as possible in 24 hours. Kate is co-author, with Donald Johanson, of Lucy's Legacy: The Quest for Human Origins. She holds a bachelor of science degree in biological anthropology and zoology from the University of Michigan.
