NASA: Humanity's first flight to Sun scheduled for July
Humanity's first mission to the Sun is undergoing final preparations ahead of its scheduled launch on July 31. NASA's Parker Solar Probe has been flown to Florida where it will continue testing and eventually undergo final assembly. The Parker Solar Probe will orbit directly through the corona (solar atmosphere), closer to the solar surface than any man-made object has ever been before. Here's more.

Extreme engineering required for the PSP to survive
For the duration of its mission, the Parker Solar Probe will be facing temperatures of up to 1,400 degrees Celsius in the Sun's corona, and will go as close as 6.2 million kilometres to the Sun's surface. To survive such a mission, the Parker Solar Probe will be protected by a 4.5-inch thick carbon-composite heatshield, which will be tested prior to launch.
What the Parker Solar Probe's seven-year-long mission entails
The Parker Solar Probe, after its launch, will embark on a seven-year-long mission in which it will explore the Sun's outer atmosphere and make critical observations to help scientists answer decades-old baffling questions about the physics of stars. Data collected will also help in forecasting major solar eruptions and subsequent space weather events which might have disruptive potential for technology on Earth.

Understanding the Earth-Sun connection
With the Parker Solar Probe facing brutal heat and radiation, the mission is expected to provide insights into what drives the solar wind - the constant outpouring of charged particles from the Sun that shapes planetary atmospheres and affects space weather near Earth. The mission, in NASA's own words "will provide a critical link in the Earth-Sun connection".
