Subject: What will happen to Voyager 1 when it encounters the Bow Shock? Thank

The reason for my question is that I have always been fascinated with space.

The region of the sun's influence know as the "Bow Shock" is typically 
depicted as a fiery area appearing hostile to vehicle traveling though it. 
When do scientists think Voyager 1 will make contact with the Bow Shock and 
what do scientists speculate will happen to the vehicle when contact occurs?  
Thank you
