Red-hot voyage to sun will bring us closer to our star

A red-hot voyage to the sun is going to bring us closer to our star than ever before.

NASA's Parker Solar Probe will get nearly seven times closer to the sun than previous spacecraft. It will hurtle through the sizzling solar atmosphere and come within nearly 4 million miles of the surface.

It's designed to take solar punishment like never before, thanks to its revolutionary heat shield that's capable of withstanding 2,500 degrees Fahrenheit. To snuggle up to the sun, it will fly past Venus seven times over seven years.

This July 6, 2018 photo made available by NASA shows the Parker Solar Probe in a clean room at Astrotech Space Operations in Titusville, Fla., after the installation of its heat shield. NASA's Parker Solar Probe will be the first spacecraft to "touch" the sun, hurtling through the sizzling solar atmosphere and coming within just 3.8 million miles (6 million kilometers) of the surface.

Liftoff is set for the pre-dawn hours of Saturday.
