Question

Dave Naughton asked:

Hi Redi/Chris

 

Pre-GPS seafaring navigators used magnetic compasses and before that they

used the stars to find their way.

 

My question is:

 

How do space-travellers navigate in our solar system and how is Voyager 1

navigating in interstellar space and beyond?

 

Loved Chris' visit to Primedia.

 

Regards
