Question: What was the ultimate destination of the Jupiter mission? The giant planet is made of gas, it has no solid surface to land on. Theoretically a spacecraft could land on one of Jupiter's moons, but they lie within the lethal radiation belt.
Answer: The ultimate goal was to orbit Jupiter to study the Monolith also in orbit around it.
Answer: The objective of the Discovery (Jupiter) mission was to locate the recipient of the powerful radio signal that was transmitted from the Moon earlier in the movie. Interestingly, the destination of the Discovery mission changed between Jupiter to Saturn and back to Jupiter during the production of the film. The Jupiter visual effects had already been shot ("in the can" as it were) when Stanley Kubrick decided to change to Saturn. It was the protest of the visual effects team, who had already spent much time and money on the Jupiter effects, that convinced Kubrick to stay with Jupiter. In the meantime, author Arthur C. Clarke went ahead and changed the destination to Saturn in his written treatment of the movie.

Question: Mary's attire looks more like 1960s than 1940s. Any info on this?
Chosen answer: This is not unusual in older films. Earlier costume designers were less attentive to historical accuracy and freely incorporated current fashion trends into period movies. It was just an accepted practice and movie audiences back then were often less discerning and/or unaware of inaccuracies. Today's costumers have greater access to historical information, do more research, and strive for authenticity.

Question: Serious spoiler alert, but this has always puzzled me. At the end of Barbarella the Black Queen unleashes "Matmos", an evil energy which destroys nearly everybody and everything in the film. Pygar (the blind angel) escapes, only rescuing two people from the cataclysm: Barbarella and the Black Queen. Barbarella asks Pygar why he saved the Black Queen after all the evil things she did (she even blinded Pygar). Pygar replies "an angel has no memory." I never got the point of that. What did Pygar mean? (In his previous conversation he recalled things that happened before he was blinded, so obviously he did have a memory.) And I could not see the point of or meaning to this ending at all. Did any of this make sense to anybody else?
Answer: You say that Barbarella was beyond lame-it was totally atrociously bad and ludicrous. It was released in autumn 1968, when I was 12, and too young to see it at the cinema. I finally got to see Barbarella when I was 18 and it was shown late one night on television. I wholly concur: I thought it was totally, atrociously bad and ludicrous, and my opinion has not changed since.
Answer: I concede your point. Perhaps I was being a bit too literal. When Pygar says he has no memory, he may not mean that all past events clear from his mind (in the way that, for example, you could delete a computer file from your laptop). Instead, he might mean he does not dwell on the past, or he does not retain bitterness or anger for past wrongs, or he does not return evil on those who were bad to him. I think the film was based on a comic that ended in pretty much the same way. All the same, I always thought the ending was rather lame. It was as if somebody told Roger Vadim (the director) "hey, this film is supposed to be 90 minutes long, but we've done 89 minutes filming, and we still haven't got an ending." So Roger Vadim got the Black Queen to unleash Matmos and destroy everything. (To be pedantic, Barbarella is 98 minutes long, but I hope you understand what I mean.) Personally I thought the ending of "Monty Python And The Holy Grail", where a police force stops the film, was a similar disappointment.
Answer: He's in the same location as Ellis Island. Thousands of years have resulted in significant changes geographically.
