先驱者-10号是第一颗到达木星附近的探测器。这个空间飞行器自1972年发射以来,飞掠了小行星带,从危险的木星辐射带中逃生,几乎无故障地运行着。到1982年3月2日,它已运行了10年,行程达66亿多公里,接收到地球发给的4万多条指令,并向地球发回了125万亿比特以上的科学数据。先驱者-10号目前仍在正常运转,并从事一项新的探测计划:确定太阳大气层的范围及其作用,以及容纳太阳和行星的磁泡。在恒星际介质中,这种磁泡被称为日光层。先驱者-10号目前正在天王星和海王星的轨道之间运行,已飞过了一半多的距离。它离太阳已达46亿公里。从现在起,大约
Pioneer -10 is the first detector to reach near Jupiter. This spacecraft has been flying its asteroid belt since its launch in 1972, has escaped from the dangerous Jupiter radiation belt and has been operating almost without any problems. As of March 2, 1982, it has been operating for 10 years and has traveled more than 6.6 billion kilometers. It has received over 40,000 instructions from Earth and sent back more than 125 trillion bits of scientific data to the Earth. Pioneer-10 is still in full operation and is engaged in a new exploration program: Determine the scope and role of the solar atmosphere, as well as the bubble to accommodate the sun and planets. In the interstellar medium, this bubble is called the solar layer. Pioneer-10 is currently operating between the orbits of Uranus and Neptune, having flown over more than half the distance. It has reached 4.6 billion kilometers from the sun. From now on, about
