A NASA spacecraft zoomed toward the sun Sunday on an unprecedented quest to get closer to our star than anything ever sent before.

As soon as this fall, the Parker Solar Probe will fly straight through the wispy edges of the sun's corona, or outer atmosphere, that was visible during last August's total solar eclipse. It eventually will get within 3.8 million (6 million kilometers) of the surface in the years ahead, staying comfortably cool despite the extreme heat and radiation, and allowing scientists to vicariously explore the sun in a way never before possible.

No wonder scientists consider it the coolest, hottest mission under the sun, and what better day to launch to the sun than Sunday as NASA noted.

"All I can say is, 'Wow, here we go.' We're in for some learning over the next several years," said Eugene Parker, the 91-year-old astrophysicist for whom the spacecraft is named.

Protected by a revolutionary new carbon heat shield and other high-tech wonders, the spacecraft will zip past Venus in October. That will set up the first solar encounter in November.

Altogether, the Parker probe will make 24 close approaches to the sun on the seven-year, $1.5 billion undertaking.
