Could it be 3d printed?

There were just as many clones of cars back then, they just aren't remembered/around today like the real thing is because people have made very little, if any, effort to preserve the "knock offs"

How can you tell? I don't see any bananas in the video

Hey! I've got an uncle that works there!/s

They're built to last and with high quality.

The 2 years of mission time just means a 99% chance to be fully functional for the full 2 years. After that it's just a matter of individual parts failing until full contact loss. So after 2 years it can still do everything it could at launch but at year 4 it's still doing some stuff just maybe not everything.

The whole 2 year but really 5 year thing is also very helpful for funding. It looks good if they can say "yeah the last mission you paid for was a 2 year mission that lasted 5"

PS: this is just my understanding of it, please correct me if I'm wrong

It also makes it easier to get the next telescope paid for when you can show everything it's done and how the country thinks about it.

I do agree though that more credit should be given to the scientists themselves
