Nasa�on Sunday blasted off a $1.5 billion spacecraft toward the Sun on a historic mission to protect the Earth by unveiling the mysteries of dangerous solar storms.

3-2-1. and we have liftoff of Parker #SolarProbe atop @ULAlaunch's #DeltaIV Heavy rocket. Tune in as we broadcast our mission to "touch" the Sun: https://t.co/T3F4bqeATB pic.twitter.com/Ah4023Vfvn

"Three, two, one and liftoff!" said a�Nasa commentator as the Parker Solar Probe soared skyward aboard a Delta IV-Heavy rocket from Cape Canaveral, Florida at 3:31 am (0731 GMT).

At closest approach, our Parker #SolarProbe spacecraft will be hurtling around @NASASun at approximately 430,000 miles per hour! That's fast enough to get from Philadelphia to Washington, D.C. in one second. Watch: https://t.co/T3F4bqeATB pic.twitter.com/RPzeX2bW65

The unmanned spacecraft aims to get closer than any human-made object in history to the center of our solar system.

The probe is designed to plunge into the Sun's atmosphere, known as the corona, during a seven-year mission.

It is protected by an ultra-powerful heat shield that can endure unprecedented levels of heat, and radiation 500 times that experienced on Earth.

NASA has billed the mission as the first spacecraft to "touch the Sun."

In reality, it should come within 3.83 million miles (6.16 million kilometers) of the Sun's surface, close enough to study the curious phenomenon of the solar wind and the Sun's atmosphere, known as the corona, which is 300 times hotter than its surface.

? Fascinating. Just watch, even if you have seen it before.

It changes your perspective ??pic.twitter.com/AYu0OGzVd2
