深空1号是新盛世计划第一次发射的航天器。该计划执行的一系列任务是为试验新技术而设计的,相信可有效地用于21世纪的科学任务。在飞行任务设计的12种技术中有一项技术是论证氙离子推进发动机。这是此种发动机作为主推进系统第一次在深空中应用。1998年4月NASA宣布,该技术论证飞行任务的发射日期将由原定的1998年7月21日推迟到1998年10月15日,发射周期一直延续到10月30日。新的发射日期不能达到原定的飞行目的地,因此必须选择新的目标。目前预定深空1号(DS1)将在1999年7月28日对近地轨道小行星1992KD绕飞。此颗小行星是从100多个可绕飞的小行星中选择出来的。它的椭圆轨道穿越火星轨道的内外。它与太阳的距离是地球离太阳的距离的3倍多,据估计其直径大约为3km。
Deep Space 1 is the first spacecraft to be launched under the new Spirit program. A series of tasks carried out by this program are designed to test new technologies and are believed to be effective for the scientific tasks of the 21st century. One of the 12 technologies designed for mission missions is the demonstration of xenon-ion propulsion engines. This is the first such deep-space application of this engine as the main propulsion system. In April 1998, NASA announced that the launch date of the technical demonstration mission will be postponed from the original July 21, 1998 to October 15, 1998 and the launch cycle will continue until October 30. The new launch date can not reach the original flight destination, so you must choose a new target. It is currently scheduled that Deep Space 1 (DS1) will fly around the near-Earth orbit asteroid 1992KD on July 28, 1999. The asteroid is selected from more than 100 orbiting asteroids. Its elliptical orbit crosses the orbit of Mars. Its distance from the sun is more than three times the distance of the earth from the sun, which is estimated to be about 3 km in diameter.
