Parker Solar Probe
Humanity’s First Visit to a Star
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°F (1,377°C)!
