Some of them were for getting more detailed information about the Moon prior to sending the Apollo missions there. But most of them were general solar system exploration.
> That's like saying Starliner's Demo flights don't count as human-rated because they were uncrewed.
No, it isn't. The counterpart in the 1960s to these missions would be the uncrewed flights of the Mercury, Gemini, and Apollo spacecraft that were done prior to the first crewed missions. I did not include those in the unmanned missions I listed.
- They sent 4 rovers to Mars, a freaking helicopter, and confirmed water presence.
- They launched 2 telescopes, with Webb forcing us to rethink our model of the universe.
- They made New Horizons do a flyby... of Pluto.
- And they collected samples from the near-Earth asteroid Bennu!
If that's not the demonstration of anything but drastically high competence to you, nothing is.
At this stage, I have to believe you are a troll.
What's the other telescope you have in mind?
And those two free telescopes from NRO are still sitting idle. One of them is supposed to finally launch after 15 years, though apparently it's in such a complex and high budget mission it might not be saving any money to use it there.
