Orion to an NEO
« on: 05/09/2007 04:46 PM »
I've heard from some it would be impossible to use orion to visit an NEO,  from others I've heard it would be great. So could Orion go to an NEO? and which one, you got any suggestions?

And will asteroid mining ever be profitable?

There is a thread on other uses for the CEV

The CEV is only a taxi to LEO. The ARES I barely gets it there.   It needs other stages and modules (EDS and LSAM) to go and do something else.   So for a NEO, the CEV would need an upperstage and a mission module

It really depends on which NEO you're talking about, but an Orion with a standard Earth Departure Stage and a LSAM modified to be more of a hab/arrival braking stage could probably go to certain asteroids. Really, it's a matter of finding a NEO with similar delta-V requirements as a trip to the moon.

Is the Ares IV option still on the table? We will not get there with Ares I and Ares V is an overkill.

If it is still on the table, it will be many years before anything like that would be possible. Ares-IV needs the Ares-V 10m core - which is a good decade away - at least. Plus, if NASA continues on the Ares track, even the lunar effort is going to be strapped for cash. There will be no money for anything but the moon, and we'll be lucky to get even a bare-bones lunar plan.

I am against a generic LEO  one.  A NEO mission will need some kind of a module, whether is is a modified LSAM or what

For any NEO mission, you need much the same hardware as you do for a Lunar mission.

You must launch the crew (CEV), have some sort of propellant to get you to the NEO (EDS) and some way to land people on the surface safely, preferably with a couple of tons of equipment for them to use while they're there (some version of LSAM).

The only real difference is going to be the quantities of propellant you're going to need to get to the NEO and then back again.

The automated cargo landings being planned for the moon will also be usable for NEO's too - allowing heavier equipment to be landed - such as mining and processing units.

Jim, I know its off-topic here, but can I ask you to expand on that.   I would like to understand precisely what your detailed definition of a "generic LEO mission module" is and then, in context, understand why you don't see a point to one.

I can see potential advantages myself, but I suspect our definitions aren't exactly the same.

Two papers on Orion NEO missions

Enjoy...
