Parker Solar Probe needs to do 7 flybys of Venus before reaching Sun

NASA's Parker Solar Probe Misson, launched on August 12, is touted to revolutionize the human understanding of the closest star to earth - The Sun.

An article in the Dayton Daily News reads: While you were hopefully out enjoying some sunshine with family or friends over the weekend, you may not have known that NASA launched a probe atop a ULA Delta IV Heavy rocket from Cape Canaveral Air Force Station in Florida toward the sun. It is set to fly into the Sun's corona within 3.8 million miles or 6.1 million km from the solar surface, seven times closer than any other spacecraft. Once it reaches space, the craft needs to drop 53000 miles per hour of sideways motion to skim the sun's atmosphere. But the wind is processed by the time it reaches Earth. In addition, the low density of the plasma in the solar corona means a relatively small amount of heat will transfer to the probe. During its scheduled seven-year long mission, the probe will go for total seven flybys of Venus. The probe was launched in a second attempt today, and it is the fastest human-made object ever. According to the National Aeronautics and Space Administration (NASA), the mission is named for Dr. Eugene N. Parker, whose profound contributions pioneered the modern understanding of the Sun.

Being the first-ever mission of NASA to "touch" the Sun, the Parker Solar mission is about the size of a small vehicle that will travel directly into the Sun's atmosphere. He theorized an explanation for the superheated solar atmosphere, the corona, which is-contrary to what was expected by physics laws - hotter than the surface of the Sun itself.

New storm forms over Atlantic; no threat to Jamaica
Continuity prevents a higher forecast, but Lane seems destined to eventually become a category-4 hurricane like Hector. Tropical-storm-force winds extend outward up to 35 miles from the center.

The corona gives rise to the solar wind, a continuous flow of charged particles that permeates the solar system.

The Team: The mission is part of NASA's "Living With a Star" program to explore aspects of the Sun-Earth system that directly affect life and society.

This mission to the sun became more urgent when, less than one year ago, a massive solar storm interfered with communication about Hurricane Irma as the massive system bared down on the Virgin Islands.
