Oumuamua: object from another star


So guys, Oumuamua is one of the most interesting discoveries in astronomy in the last years.
An interstellar object that offers many possibilities and questions.

Let us speculate.
1) it is viable to use it as "a ride" to other system? Can we do it? Will we do it?
2) what about the "organic cover" found in it?
3) do you believe it can be other thing besides an asteroid?

While Oumuamua was fascinating I don't see it as the most
interesting discovery, since recently astronomers have discovered so much.
About 1): Why not take a ride? Then we would arrive at some nearby star in a very short time. Only a few million years at best.

Even if a mission could catch Oumuamua, which would be a huge challenge given it's a fast mover and already outward bound, there'd be other problems. Its tumble would have to be radically altered to provide a 1 g environment for long-term human habitation - long-term probably meaning millions of years, as noted above.

Then there's the cosmic ray menace. Carving a habitat inside Oumuamua might solve that problem, but excavating would be much easier said than done, especially since it's apparently mostly metal.

Even if it could be prepped and occupied for the long term, what would be the point? Unlike Dark Star's crew, people living on Oumuamua couldn't zip around from one star system to another in a matter of days. Also like Dark Star, extreme boredom would have to be dealt with, especially after the first ten or twenty thousand years.

Last but not least, Oumuamua's crew would have to be alert for road hazards, although avoiding things like rogue black holes would certainly solve the boredom issue.

I'm not talking about humans offcourse. Probes.
Object velocity is far superior than our probes going/in outside solar system.

Regarding being a great discovery: I don't see anything bigger since LIGO gravitational waves and New Horizons Pluto flyby.

Yes, it'll be hard to top that Pluto flyby, although the oceans of Europa and/or Enceladus may have bigger surprises in store.

Back to Oumuamua, it's already outbound at 27 mph/sec, but heading nowhere special. Once the requisite technology is available, I don't see any reason to target it with a probe that can move fast enough to catch it, instead of sending one to Proxima Centauri, which reportedly has a planet in the Goldilocks zone.

Then it may be just me fthinking discoveries of multiple planets systems, far away large structures, galaxy clusters and many other just as fascinating (sometimes more).

They should have tried to land something on it and slow it down. This type of asteroid is very useful for a primitive civilization with limited space capability. This is a proven "naturally" occurring interstellar platform that can be re-used for space exploration or base withing a system by fitting it with engines and living quarters. What an idiotic missed opportunity and vision. A gift wasted.
More may be come though. I have a feeling something bigger is trailing it.

A pragmatic remotely possible usage of that object would be to use it as a taxi [cab] for a squadron of probes with the purpose of analyzing the space out of the "heliosphere". Voyager 1 has left the heliosphere in September 2013 [when the devices on board recorded a clear change of environment: from solar wind to interstellar plasma].

But Voyager probes [like the Pioneer ones] weren't projected and built to study the interstellar space, so Voyager 1 is sending us just some information.

On a so wide object we could put an entire automatic station to study the interstellar space. But the costs would be exorbitant! [Astronomical, I would say in this context].

Exactly my point my friends!
What a wasted opportunity, a mission that should had happen with international colaboration.

Fast ride my friends...
