Parker Solar Probe: Nasa’s daring mission to unlock Sun’s mysteries

BBC: The American space agency (Nasa) is all set to launch one of the most daring ventures in its history.
It’s going to send a satellite closer to the Sun than any mission has done before.The Parker Solar Probe will dip directly into our star’s outer atmosphere, or corona.
The spacecraft’s data promises to crack longstanding mysteries about the Sun’s behaviour – assuming it can survive roasting temperatures above 1,000C.
Parker will begin its quest with a ride on a mammoth Delta-IV Heavy rocket.
This powerful vehicle is scheduled to lift off from Cape Canaveral, Florida, at 03:33 local time (08:33 BST) on Saturday. The Delta will hurl the probe into the inner Solar System, enabling the Nasa mission to zip past Venus in six weeks and make a first rendezvous with the Sun a further six weeks after that.
