I came into the Army Signal Corps in MOS 31F - Mobile Subscriber Equipment Switching Systems Operator. It's the equivalent of a telecomunications engineering position. Learned all about digital encryption, multiplexer technology, methods of transmitting multichannel links, how to run the software that made it all work (it was some kind of *nix by the way), and actually build the network from the ground up.
Then, a Master Sergent at Fort Sill noticed my technical ability w/ computers when I came back from Korea and he put me in 75th Field Artillery Brigade's IT department. I got experience and training that enabled me to get into the workforce and work as a IT guy / programmer without having a degree. Employers see the military experience on the resume, and it counts for something.
However, I didn't re-enlist. The pay sucks.

Officially, the plans for the Saturn were destroyed as part of a deal so that NASA could get funding for the Space Shuttles.
The object's orbital plane is at nearly right-angles to the earth's orbit around the sun, and its period is actually longer than Earth's. In order to intercept, you'd have to:
- Match orbital planes with the object. I remember reading somewhere that the further you are from the object you are orbiting, the less delta-V this requires.
- Boost out to the object's orbit via a transfer orbit. Not too hard once you've changed the orbital plane.
The lauch of a "deflection" mission would have to be well timed. As far as how you would "deflect" the object, I am unclear. The 2 options available are to
1. Change Apogee / Perigee by appying acceleration prograde/retrograde at the appropriate point in the object's orbit.
2. Change the object's orbital plane.
Either way, this is beyond our technology. The thing orbits close in to the sun with a low eccentricity. In other words, its moving at a pretty good clip and it's massive. You'd need a very large impulse to change the orbit signifigantly
I was looking over the JPL's orbital elements and diagrams for this object (here), and I noticed the following:
15 March 2005: The object will be.082 AU from earth.
24 September 2012: The object will pass within 0.098 AU of earth.
I also noticed (if I am reading the orbital diagrams correctly) that the points where the object is closest to the earth coincide with the points where the object passes through the plane of the ecliptic. Since these are the Acending / Decending nodes of a solar orbit, wouldn't this point be ideal for a change of orbital plane? I'm thinking these near-Earth encounters may change the object's orbit somewhat, since surely the earth encounters will impart some delta-v on the object.
Anyone else up on orbital mechanics care to take a better look at the ephermis?

Assuming that the

Delta-V adds up pretty quickly....

Anyone else up on orbital mechanics care to take a better look at the ephermis?I just bought a new package PC and a 17" LCD could be bundled with it for $149 more than the price for a 17" CRT - a no-brainer for me!
