If someone already has an existing thread, please move this there.

Launch is scheduled for summer of 2018 unless there have been snags since this news update last July.

Next flight up for the Delta IVH & only the second non-classified civilian flight for the launcher since it has been in regular service after the Orion boilerplate test flight.

I think that Solar Probe was an idea first proposed back in the 1950s, although it could have been 1964. It took a long time for a bunch of things to happen to make it possible. That included technology development, but also time for enough people to declare that it was important to do.

The concepts have evolved a lot. Back around 2006 or so the concept for Solar Probe involved several RTGs (nuclear batteries) because they did not know how to use solar panels that close to the sun. There was some technology development that enabled them to come up with high temperature systems so they could do the mission with solar.

If you want to see some clever design, look into the design for the solar panels on SP+. The panels actually retract as they get close to the sun, but they have small tips that still stick out a little bit to provide some power.

There were allot solar probes proposals in 1960s and 1970s

Most used RTGs (nuclear batteries) because the detour to get to sun via Jupiter !
there it get sling shot by Jupiter gravity toward the sun.
after a 5 year trip the probe would burn up as it approach Sun surface 
I love Strange Technology
