Missions
Humans have been observing the Sun basically since the beginning but it was not until the early 1960s that spacecraft were used to observe the Sun. There have been many missions since that time that have furthered our understanding of the Sun as well as providing many new questions to answer.

Parker Solar Probe is a historic mission, flying into the Sun’s atmosphere (or corona) for the first time! It will have 24 orbits around the sun, traveling at a top speed of 430,000 mph—the fastest man-made object ever! It can also withstand temperatures outside the spacecraft that reach nearly 2,500 degrees Fahrenheit (1,377 degrees Celsius)!
