NASA Is Determined to Send Innovative Mission to the Sun

"But until you actually go there and touch the sun, you really can't answer these questions", like why the corona - the outer plasma-loaded atmosphere - is hotter than the actual surface of the sun, said mission project scientist Nicola Fox of Johns Hopkins University's Applied Physics Laboratory. "And we're very proud to be able to carry Gene's name with us on this wonderful voyage of discovery".

Nasa Washington Science Mission Directorate associate administrator Thomas Zurbuchen said: "This is the first time Nasa has named a spacecraft for a living individual".

The spacecraft will orbit about four million miles above the sun's surface. By going to the sun, rather than simply pointing a telescope in its direction, scientists hope to solve prevailing mysteries about its fiery atmosphere and its storms that can create huge problems here on Earth.

The spacecraft will be subjected to extreme heat and radiation from the corona, where temperatures are almost 1,377C (2,500F).

NASA spacecraft have traveled inside the orbit of Mercury, the innermost planet.

The mission will provide "priceless information" about how the Sun's corona - its outer atmosphere - is heated to temperatures in excess of a million degrees Celsius, Lunine said.

The Parker Solar Probe is scheduled to launch during a 20-day window that opens July 31, 2018. Dr. Parker may be 89 years old, but he's still kicking-serving as the S. Chandrasekhar Distinguished Service Professor Emeritus of the University of Chicago's Department of Astronomy and Astrophysics.

NASA has sent unmanned probes to the farthest reaches of the solar system, and beyond.

The sun is 93 million miles from Earth. "One would like to have some more detailed measurements of what's going on in the solar wind". Resulting solar winds are powerful and pose huge risks to satellites, space travelers and to telecommunications and the power grid here on Earth. I'm sure that there will be some surprises.

The first paper that Parker submitted to the Astrophysical Journal proposing the solar wind was panned by two eminent reviewers. Also included on the probe are solar panels to power the probe's journey; magnetometers; a radio antenna; a FIELDS Antenna to record "radio emissions coming from the sun" and an SWEAP SPC that will "gather solar wind particles".
