If mankind ever finds a way to send a spaceship to explore the surface of the sun, is it possible for it to send a radio signal back to earth? Is it possible for Houston to transmit a command to the craft from Earth?
Edit: I'm aware of the 8 light minutes between the earth and the sun. Delay and interference are expected. My plot speculates that the craft can "fly" in the Sun's atmosphere and sometimes "dive" into the convective zone. I'm trying to figure out the possibility of maintaining communication with earth when the craft is inside photosphere, chromosphere and convective zone. It would be nice if the pilot could say "Houston, we have a problem." from the Sun!
