NASA to send solar probe closer to sun than ever before

The Parker Solar Probe will embark on a almost seven-year venture, becoming the first spacecraft to have a direct encounter with a star.

The probe is relying on a 4.5 inch carbon heat shield which has taken 10 years to develop and which is so strong it will survive for billions of years even when the rest of the spacecraft has disintegrated.

Scientists hope to unlock mysteries such as why the sun's corona, the outermost layer of its atmosphere, is hotter than its surface.

The last time a man-made object came close to the star's surface was in 1976 when Helios 2 achieved perihelion, point of the orbit at which it was closest to the sun, at 27 million miles. The probe will use Venus' gravity to slow itself down as it makes its close approaches with the sun.

Additionally, the Sun is the only star we can study up-close, and any insights we glean from the Parker Solar Probe could help us better understand how other stars function.

France also initiated NASCAR's substance-abuse policy, which offers a "Road to Recovery" to any member that fails a random test. It's a great sport and we go forward and we all should be very protective of it and be willing to lend a helping hand".

The probe is expected to take flight atop a Delta IV Heavy rocket at 3:33 a.m. ET on Saturday, ironically launching to the sun in the dead of night from Cape Canaveral Florida.

The spacecraft is named for Eugene Parker, the scientist who first predicted the existence of the solar wind - fast-moving solar particles that stream through the entire solar system.

Nasa aims to collect data about the highly magnetised corona.

As NASA explains, the probe's first challenge will be to cancel out the speed at which the earth is moving in relation to the sun.

Understanding more about solar activity could help scientists forecast the large eruptions from the sun that pose a threat to satellite and communications systems.
