Re: No advanced propulsion?
No warp reactor either, Well, jokes aside, the article mentions "solar electric propulsion for capturing and redirecting an asteroid." Perhaps NASA can adapt that to the Orion.

Re: Visiting asteroids
@SaneIT I've heard of those planets, but they are even further than Mars, so it'll be quite a while until we can actually draw on their raw materails. As for mining, well, even on earth is not without controversy.  The space supply chain piece is not up here.

Re: Visiting asteroids
1. they would have to first analyze what's out there are be sure it is safe and usabel.

That seems to be something that is already being done.  I've seen several reports about planets of diamonds and we know planets in our solar system are either solid or gaseous. Using them as a sort of rest stop makes sense even if we just stay in our own solar system exploring things.



2. mining space bodies in that way may be seen as a kind of cosmic vanadalism, depending on one's perspective. 

 

I never thought of it that way.  I guess I see it as using the resources at hand.  We have flags and a car on the moon and have crashed ships into Mars, if the space industry has been OK with doing that I have to wonder why mining would be seen as vandalism.

Re: Visiting asteroids
@SaneIT that is not part of the plan for the immediate future. It would be problematic for a few reasons. 1. they would have to first analyze what's out there are be sure it is safe and usabel.

2. mining space bodies in that way may be seen as a kind of cosmic vanadalism, depending on one's perspective. 

I believe the supplies would all be coming from earth, though it would be simpler and easier for a space station to stock the materials and then make what it needs on demand without having to wait for a delivery from earth. Also for the plan of having some midway sites, again, just having to have materials available rather than finished products -- which entails predicting exactly what is needed in all cirumstances -- would make the supply chain more viable.

Re: Visiting asteroids
In the name of supply chains for space did you address using planets/moons for collecting raw materials?  Watching the rover on Mars that just keeps on going one day, I stopped and wondered to myself what if it could have assembled a little mining camp before it went out to collect rocks.  Could future space travel be supported by autonomous mining operations where ships could stock up on materials needed to run their replicators or 3D printers?

Re: Visiting asteroids
SaneIT, 

My thought was because according to recent research AI and robotics have made great advancements engineering ethics and emotions into autonomous robots. It would make sense to have at least a combined crew rather to rely on only humans.

Re: Visiting asteroids
@SaneIT exactly!  The piece I wrote on supply chains for extended space voyages both opens and closes with references to the replicator. I think we'll have to make do withoutr the perfect cup of Early Grey (which makes me think of the failure of the machine to make tea in the Hitchhiker series). But we should be able to produce some necessary supplies and equipment on demand in space as the technology advances.

Re: Visiting asteroids
I guess I'll have to keep an eye out for that blog post.  

 

One of the things about 3D printing in space that I've wondered about is when there will be a printer that can collect printing media from space to build parts or even a new probe via plans sent from Earth.  The benefits of launching a spool of plastic media for printing small parts is obvious when you consider that the option is sending dozens if not hundreds of spare parts.  I can also see the usefulness when things go a bit wrong and a specialized tool would save hours of frustration.  Of course the end goal is Star Trek replicators but I think we've got a bit of a wait for those.

Ticket to mars? Check return flight date
When they issue you your ticket to Mars, carefully check the return flight date. It will take 6-8 months to get there, depending on where in the Hohmann Transfer Orbit that you launched. More calculations needed to determine length of the return flight.

NASA's Orion Spacecraft 9 Facts
I think tha it is in fact important to develope a asteriod deflection system. Better be careful that they do not accidently mis-calculate.

To use it to put humans into outer space is great (and then onto Mars). However I think it could be better used to establish a moon colony and to setup training for outer space there.
