It strikes me as a solution in need of a problem. The cost to orbit is almost 30x per kg of that offered by Spacex. The supposed selling point is that the relatively small throw weight offers mid-size customers the orbital parameters of their choosing (taxi vs bus) but it's hard to imagine who would find that worth the added cost.

Intelligent/advanced life is entirely different than intelligent design. We have proof of the former in ourselves, and it’s a testable theory even if we haven’t found any signs yet in the vastness of space. The latter — intelligent design — is faith and not a field of scientific study.

>But scaling it down and using a tennis ball or a marble to represent either earth or the solar system could it be possible?

​

it is not possible to print a picture of the solar system to scale.

either the distances are too big, or the planets are too small.

On a dry lakebed in Nevada, a group of friends build the first scale model of the solar system with complete planetary orbits: a true illustration of our place in the universe.

The Sweden Solar System is the world's largest permanent scale model of the Solar System.

The York Solar System model is a scale model of the Solar System, spread out along 6.4 miles (10km) of the old East Coast mainline railway. Along it you can find scale models of all the planets in our solar system as well as models of the Cassini and Voyager spacecraft.

No, I’m not suggesting you need to keep accelerating. The speed aspect is only one reason you might want to save on the fuel you take, how do you plan on slowing down? If you could somehow mine the asteroid for fuel, this may be a possible solution.

You could also send smaller payloads that all reach the ship more easily and coalesce to fully establish sensory instruments and research stations. Rather than trying to get one heavy ship to a high speed and then somehow slowing it down.

I mean, it's not my theory, I'm most certainly not an astrophysicist either, so it could well be a primordial one, sure. I think the documentary in which I saw it mentioned, and I couldn't tell you the name, they're my background noise, the idea that it was captured as opposed to native to our solar system.

>For some in industry, though, spending as much as $1 billion to bring down the station sends the wrong message and is also a missed opportunity to instead repurpose elements of the station, recycling material that could be used for other commercial applications.

exposed to temperature extremes, radiation and pressure for decades.

how do you assess fatigue?
