美国宇航局下属的喷气推进实验室近日表示,1977年发射的“旅行者”1号飞船经过漫长的旅行,已飞出了太阳系的激波边界,即将成为第一个进入太阳系外空间的人造航天器。经历了近28年的飞行后,“旅行者”1号目前距太阳近140亿公里。它所在的区域里,太阳的影响已急剧减弱,带电荷的太阳风急剧减速后已变成了稀薄的恒星间气体,这里被称为太阳风鞘。 The NASA-affiliated Jet Propulsion Laboratory recently stated that the “Voyager” 1 spacecraft launched in 1977 has travelled a long distance from the solar system’s shock border and is about to become the first manned spacecraft to enter the space outside the solar system. Device. After nearly 28 years of flight, “Traveller” 1 is currently nearly 14 billion kilometers from the Sun. In the area where it is located, the influence of the sun has abruptly weakened, and the charged solar wind has rapidly decelerated into a thin interstellar gas, known as the solar wind sheath.
