You can’t get anywhere near the Sun because our star is too hot for a human being. The Ancient Greeks warned about that with the myth of Daedalus and Icarus.
It’s been thousands of years since then and technology has made giant leaps forward. Now man can attempt to get to know the sun better from close up, to get unprecedented information on its behaviour.
There are two new projects on the go that are separate but sure whose results will be coordinated. One is the Parker Solar Probe, which NASA launched in August 2018. The other is the European Space Agency’s Solar Orbiter, which set off on 10 February and is Italian in much of its design and content.
