Do you think NASA's Voyager program will ever send back more pictures?
user
Well, I don’t know what’s currently on the schedule for NASA, but Voyager 1 has certainly finished its primary mission, so it’s possible that the Voyagers may have enough power to take pictures in the future.  In fact, that’s likely, based on the way Voyager 1 currently is operating.

Do you think Voyager 1 has been more successful than Voyager 2?
user
I guess I don’t really know how to answer that.  There are certainly different ways to quantify success, and different people could have different opinions on what success means.  For example, in the scheme of things, Voyager 1 has traveled much farther than Voyager 2, since it’s already past the orbit of Neptune.  But then again, Voyager 2 has been traveling for a much longer time, and is therefore likely to have traveled much farther in terms of actual distance.  I think one way to look at this is that Voyager 1 has had some technical difficulties and is at risk of failing, while Voyager 2 has been more fortunate and has therefore had more chance to achieve a few “technical feats” of sorts.

Actually, that was Voyager 1.

I’m not sure I understand the question.  If you’re asking whether the whole family of Voyagers is capable of taking a “portrait”, I’d have to say no.  But maybe you’re asking if Voyager 1 took the “Portrait of the Solar System” image?  In that case the answer is yes, it’s the most famous photo taken by the Voyager 1.
