I'm not sure I understand that statement - or your link. The biological limits on deep-space exploration come from cosmic rays, not X-rays. Completely different types of radiation. And what does this have to do with left vs. right?
Taking your questions in reverse order:
1. Plenty
2. Aerogels are cool. And very versatile. Ask yourself what problem radiation shielding represents to a space vehicle. One must balance protection effectiveness with weight (because every gram matters when launching things).
3. And finally, we can definitely tell who’s a problem solver vs. somebody who points them out, then jumps up and down.
“Hey - Bob?”
What’s up, Jim?
“You know, up in space the astronauts’ tools and gear are going to floating around in zero G. How are they going to handle jobs with multiple tools if they’ll just float away?”
Lemme think…what if we made a re-usable adhesive?
“Might outgas in space or lose effectiveness. Static electricity won’t work either.”
What if we made a ‘zipper’ of sorts, except instead of metal we hook a bunch of stiff fibers together? This Swiss dude was trying to replicate seeds sticking to his pants and has a cool idea.
And thus…Velcro was popularized.
