NASA has launched a spacecraft to the sun that will fly closer to our star than anything ever sent before. The Parker Solar Probe rocketed away from Cape Canaveral, Florida, early Sunday.
The spacecraft is on an unprecedented quest that will take it straight through the wispy edges of the corona, or outer solar atmosphere, just 3.8 million (6 million kilometers) from the sun’s surface.
Protected by a revolutionary new heat shield, the spacecraft will fly past Venus in October. That will set up the first solar encounter in November. Altogether, it will make 24 close approaches over the next seven years.
Thousands of spectators jammed the launch site, including 91-year-old astrophysicist Eugene Parker for whom the spacecraft is named. He proposed the existence of the solar wind 60 years ago.
