I hope they remember to make sure there aren't any aliens hidden inside the asteroids.

Humor aside  they actually found two more "Lucys"* i.e. skeletons of Australopithecus afarensis. One is an adult male and the other is a young child.  Even better are the two Australopithecus sediba skeletons found next to each other.

*"Lucies"?

What about the Linus mission? The Pigpen mission?

The Charlie Brown mission will bring back samples.  And every time it grabs a sample it will send back the signal.

This one is one of the more adventurous satellites NASA has launched, electronically speaking. Comms, flight computers, optics processing, etc. that has never been used before.

And considering its mission parameters, if it succeeds it'll be good news for more adventurous missions in the future.

See? You start out not identifying which group of Trojans you are going to investigate, and eventually people start posting about this being a "satellite" and not a probe.

I am probably wasting my time, but this is most interesting for me for the navigation which will be necessary. I assume they are going after the leading group of trojans, after which they might gravity assist around Jupiter and return to Earth? Is that the mission?

And it is interesting because, as most people are prone to forget, these "asteroids" are not in the asteroid belt, but beyond it. That point is also interesting in terms of navigation.

I find the whole thing beautiful and far beyond our intuitive ideas of stellar space as some disk, or basically flat rubber sheet. It is more like a skate park. There will be opportunities for low-energy, low-speed, low-cost probes all over the place as our sensing and computational resources increase. Once we figure this out, and it will not take long, we can start working with larger masses and we can work more with non-Earth resources.
