The mission, formerly known as the Solar Probe Plus, was approved in 2017. On Wednesday, the spacecraft was renamed to honor University of Chicago physicist Eugene Parker, who in 1958 correctly predicted the existence of the solar wind, a continuous stream of charged particles that come off the sun and permeate the solar system.

这一探测任务在2017年得以批准，之前名为“太阳探测+”。本周三，为纪念芝加哥大学物理学家尤金-帕克，探测器被更名。尤金-帕克在1958年正确预测了太阳风的存在。太阳风是从太阳射出并渗透进太阳系的连续的带电粒子流。

“It was a fundamental insight that forever changed the way in which we understood the sun, the heliosphere and in general interplanetary space,” said Eric Isaacs, executive vice president for research, innovation and national laboratories at the University of Chicago.

芝加哥大学研究创新国家实验室副主任艾瑞克•伊萨克斯说：“这个发现从根本上改变了我们理解太阳、太阳风层和总体星际空间的方式。”

The spacecraft, designed and built by the Johns Hopkins University laboratory, is scheduled to launch in July 2018 and fly around Venus seven times to get itself into orbit around the sun in December 2024. NASA is paying about $1.5 billion to build and launch the spacecraft.

太阳探测器由约翰霍普金斯大学实验室设计并建造，计划于2018年7月发射，探测器将围绕金星飞行7圈并在2024年12月进入太阳轨道。美国宇航局为建造和发射太阳探测器支付15亿美元。
