NASA solar probe launches overnight

(WAFF) - On Friday, the Parker Solar Probe mission and launch teams concluded a successful Launch Readiness Review. There are no technical issues being worked at this time.

Teams are proceeding for a launch at 2:33 a.m. Saturday on a Decatur-built United Launch Alliance Delta IV Heavy rocket with NASA's Parker Solar Probe. Click here to watch the launch.

The Parker Solar Probe, with a key instrument designed and developed at the University of Alabama in Huntsville and the Marshall Space Flight Center, will provide unprecedented information about our sun.

The sun's ever-changing conditions, its wind and storms can spread out into the solar system, affect Earth, our cellphones, our power grids, airline communication and much more.

This is a seven-year mission where the spacecraft will fly directly into the sun's atmosphere from a distance of, at the closest approach, approximately 4 million miles from its surface.

The spacecraft will trace how energy and heat move through the sun's atmosphere and explore what accelerates the solar wind and solar energetic particles.
