Any space craft that will ever be sent to get data from the corona will be expendable. They will be hardened in an effort to have them survive as long as possible. An example of this is when we send unmanned vehicles to Jupiter and parachute them down in the atmosphere until that have a catastrophic failure. We receive telemetry data from them until that failure.

I agree with Holden. We are not sending spacecraft in the corona (yet).
However, it must also be noted that there is a dfference between "heat" and "temperature".
Temperature is a measure of the amount of energy in individual particles (e.g., atoms). The higher the temperature, the faster individual atoms are zooming around, banging into each other.
Heat is the total amount of energy available to raise the temperature of a body. If you put your hand inside a very hot oven, all the atoms zooming around will hit atoms of your hand and cause them to increase their own temperature.
In an oven on Earth, there are lots of atoms in an oven.
In the corona, the density of atoms is a lot less. Even though each atom is zooming by at speeds that indicate a temperature of millions of degrees, there are so few of them that the rate at which "heat" is tranfered to the spacecraft may be slow enough to allow it to survive (for some time -- if you wait long enough the temperatures must become equal).

For precisely an analogous reason which you would be able to stick your hand into an oven heated to 450 stages and not get burned. Air does not have a severe degree of density and so it does not maintain an excellent style of warmth potential. on the different hand, in case you touch the steel interior the oven it particularly is additionally at 450 stages, the density of the steel helps it to maintain an excellent style of warmth potential. on the third hand, it particularly is real that spacecrafts are actually not uncovered to the corona of the sunlight. even nevertheless, it particularly is something to be prevented till we actually invent metaphasic shields ala megastar Trek.

what spacecraft do you know of that has gone through the corona [ or even a coronal mass ejection ]....& survived to report back on it,s experiance?

Because they do not go there.
