There is difference between an orbiter and helicopter drone.
Orbiter is much less likely to crash and scatter across the landscape.

Pride of lions can actually bring down young elephants - not full sized adults of course, but... adolescent probably would be a right word. Packs of wolves were recorded hunting down moose. Baby mammoth separated from the mother probably would be in their range. Same for bears and tigers, though they do not hunt collectively, which limits their capabilities.
All in all, i would be more worried about poachers. And dumb politicians thinking they are entitled to such trophy on the wall.

Now for three days of floating. And return to Earth.

Stream start! Music start! Go Inspiration 4!

Your hypothetical EM-climbers would be Big Eaters, so i hope they are very, very good at agriculture too.
Someone better at math than me can hopefully calculate how much energy you need to run through electromagnet, to keep circa 100 kg stuck to a wall for any appreciable length of time - but i can assure you that normal human body can produce only a fraction of required power. Your EM-aliens will need to eat a lot to cover nutritional needs. Which will require very robust digestive system. And equally robust nervous system\conductive structures to transfer produced energy to hand and feet. Robust = big. Unless you want to stuck micro fusion reactors from "Back to the Future II" in their bellies.
Aside from basic body plan, i don't think your creations would be very human-looking in the end.

True that. IMO only Hubble launch was close in the level of tension. ISS was even more important, but it was launched piece by piece.
-
One step closer.

I will listen to an Earth-shattering KA-BOOOMMM!!!
Alternatively, I will be hearing only myself, yelling "THEY DID IT!!!" again and again.
-
Eh, I'd pay no attention to any long-time plans. Things change every time someone has a new, better idea. Or it turns out previous "good idea" won't work. Which isn't a bad thing - it keeps wheels of technological and scientific progress turning

"You are late!"
"Yes boss, I know and I'm sorry - but there was this huge space station blocking the road...""Are you drunk too?!?"
"I have proof."
...
"OK, i gotta say - It's not something you see every day."

Looks like SpaceX stole all of ferociter from BO - leaving them only with gradatim.
-
Well, BO certainly does not have anything that can be considered immensely complex and high risk.

Why do i have horrible feeling you are imagining a Cenobite, when you're talking about this suit?
-
Paper. Or rather plates of plant fibers glued together with adhesive, then pressed into required shapes.
Lightweight, surprisingly strong, cheap (if you have enough hydroponic farms). Also, because it's organic, it provides a bit of extra radiation protection.
-
Yes.
But there is difference between "Destroyed in operation" and "Refuses to even start, for reasons unknown".
One is a car that breaks on the road under the mechanical stress. Which is unfortunate but normal, even expected thing.
Other is a brand new car that can't leave the dealership, because its engine won't start. And the cause is a factory fresh component worth 20$ inside the engine, that refuses to work. Which is embarrassing and a proof of shoddy craftsmanship.

Exploding Raptors are nothing, compared to Boeing valves.
Seriously? You are comparing whole rocket engine at full thrust to a freaking valve? A sub component that has only two modes: open or closed.
Only Boeing valves apparently have three modes: open, closed and maybe, but mostly not.
-
TL;DR
"There's nothing wrong with the valves. They just refuse to work, and we don't know why."
-
Finally. Another day, another misguided fan of ORION regained his senses.
If you still have any lingering doubts, remember those two words: Fuel. Cost.
Rocket fuel tends to be dirt cheap compared to the hardware it propels. As it should be, considering how much of it is needed.
If you have sufficiently powerful nuclear engine, any gas or liquid can be fuel.
Hydrogen bombs? They ain't cheap, boyo. Or easy to make. Or store in necessary amounts... without letting the Sun out of the can prematurely
Refueling might be a problem too, if your destination point doesn't have a stockpile of H-bombs ready.
Project ORION: awesome on paper. Impractical anywhere else.

(don’t know how to add a quote in from my phone—we’re in CO on vacation)
“The launch was scrubbed after engineers received what Boeing said “unexpected valve position indications in the propulsion system” of the spacecraft. The signals came from more than half of the 24 propulsion valves in Starliner’s service module, according to the source, who insisted upon anonymity due to not being authorized to speak to media.”
More than HALF of the valves? Even if that was a false signal from sensors... dang.
This thing is a deathtrap.
-
Good job, Boeing! Another attempt, another failure.
I bet astronauts assigned to the crew feel better and better.
-
Soooo... give Starship a lifting body profile and stretch the airbraking\gliding phase? Something like a wingless Space Shuttle that still lands vertically.
-
Wheeeeewwww!!!
Driving to work early morning, I've heard in the radio that Starliner launch will be delayed, because of problems caused by "Nauka" docking to ISS!!!
Remembering some of my own, less than stellar attempts at docking in KSP, my first thought was "Did "Nauka" ram into the ISS!?!"
It's good to learn everything is more or less OK spaceside.
-
I know. It wasn't a pleasant moment. I admit my mind definitely started wandering into dark places. But everything ended well

We know Blue Shepard has tested in-flight LES. Surely they could use that system if the normal stage sep process failed. But I don't know why it would fail.
During the broadcast it got a little awkward around the time of stage sep, when the announcer lady told us that we would see the capsule separate from the booster. Instead, that was not visually obvious (probably because we were looking at something through a telescope that was 100 km away, and was kind of just a fuzzy blob at that point). Is that what has suddenly got people talking about "what if the capsule separation fails"?
I experienced the same anxiety, when there was no visual follow-up to "Separation" announcement. But this might be a KSP player paranoia
After all, "Check your staging!" is popular in our circle for a good reason!

Thems the fightin' words!
At least his dad has a buddy with whom he can wax poetically about space. When I'm geeking over something awesome and space related, my family usually tells me to keep it down and not yell too loud. Hmph.
