A spaceship is flying to the sun in summer 2018! It will be the first-ever to a star and will be one of the biggest achievements space exploration (探险) in human history. The purpose is to study the sun’s outer atmosphere and better understand how stars work.

The spaceship, with no man inside, will fly within 4 million miles of the sun’s surface - right into the solar atmosphere, where the temperature is over 4,500°C. To protect the spaceship, it is covered with a 12cm-thick coating.

The spaceship is called Parker Solar Probe and it is named after Eugene Parker, a professor from the University of Chicago. It’s the first NASA spaceship to be named after a researcher who is still alive. In 1958, Eugene Parker first created the term “solar wind”-the sun sending out a flow of particles (颗粒) and energy.

“The spaceship is going where it has never been before. It’s very exciting that we’ll finally get to know more about the solar wind. I’m sure there will be some surprises. There always are,” said Professor Parker.

Parker calls it a heroic scientific space adventure, and he means that the spaceship will have to experience high temperatures and sun radiation (辐射). “The spaceship is going to do the hottest and fastest work. I love to call it the coolest hottest work under the sun,” said Scientist Fox Nasa.
