I read people disappointed there was not more science done on the flight around the Moon.
There was a plan to combine asteroid science, asteroid deflection, and space resources work with Orion spacecraft tests in lunar orbit.
Donald Trump & Republicans then in Congress canceled that plan in 2017.
I here refer to the Asteroid Redirect Mission plan.
It would have cost an additional few billion dollars.
But I still like the idea of demonstrating gravity-tractor asteroid deflection.
I forgot about how cool the journey to Mars plans were during Obama's term IIRC. Building the hugest-ass rocket, lassoing an asteroid to the moon.
Then I stopped thinking about it when Trump happened and I expected it's never gonna happen.
For accuracy:
The Asteroid Redirect Mission proposed to enclose the rock it would have picked up inside a large bag - otherwise, it would have fragmented and drifted away.
There were jokes about getting endorsements from trash bag manufacturers, but the reference design was a coated Vectran weave similar to Mars lander airbags. Known material, good radiation tolerance, heat stable, etc.
Something like ARM could come back. But not with the current management.
