美国国家航空航天局(NASA)与加利福尼亚大学的科学家联合研制了一个发往火星的麦克风,它已于今年1月出发,预计今年秋天到达,届时,地球人就可以听到来自火星的声音了。这个麦克大小如同一个火柴盒,其底面积约5cm~2,厚1cm,重56g。整个研制过程共花费了10万美元。预计,这个麦克风将在火星上连续工作1个月的时间,每3d发回10min的声音信号。通过“探路者”飞船发回的图片,人们都已经知道火星是一个堆满了碎石的橙色星球,然而,火星上的风声、沙暴声等一系列的
NASA and scientists at the University of California have co-developed a microphone to Mars, which departed in January this year and is expected to arrive this autumn when Earthworms will hear the sound from Mars. This Mike is the size of a matchbox with a base area of about 5cm 2, a 1cm thick, and a weight of 56g. The entire development process spent a total of 100,000 US dollars. It is expected that this microphone will work continuously on Mars for 1 month, send back a 10-minute sound signal every 3d. Through the “Pathfinder” spacecraft sent back the picture, people already know that Mars is a orange planet filled with gravel, however, the wind on Mars, a sound of sandstorms and a series of
