When the first humans venture beyond the Solar System, our present-day experiences with the Voyager and Pioneer craft will be remembered as watershed moments. Our space craft presently experience a space environment that would harm human tissue and would dampen the spirits of the hardiest souls. The specific case is how Coronal Mass Ejections of the Sun are experienced by the these craft. In spite of the fact that the Voyager craft are entering Interstellar Space–the craft are experiencing the effects of the CMEs.
So raise a champagne glass, a beer mug, or your cup-of-joe to these space craft–for Auld Lang Syne.
