For the record. So much of what you have stated above is so inaccurate that it makes it pointless to try and argue with you.

Example: You suggest that it would be easier to collect the debris than to deflect it into a decaying orbit. Do a little research and you will find that the 8000 or so tracked objects represent a total mass of approximately 3000 tonnes. Where you gonna put it? Some pieces are 20 metres in length.

Example: You suggest that it is "easy to dodge space debris". The 8000 tracked items represent only those pieces > 10cm. They are but the tip of the iceberg. There are estimated to be upward of 100,000 (maybe as high as 500,000) pieces 10cm<debris>1 mm. A "spec of paint" was enough to punch a pretty substantial hole in the "bullet proof" window of the space shuttle. How do you dodge something you have no idea is coming? (Not to mention that "station keeping fuel" is one of the major limitations upon the lifetime of a satallite.

For example. One of the major roles of the 1.3 billion Euro ATV, is to use it's thrusters to regularly push the ISS higher to compensate for its otherwise rapidly decaying orbit (Remember that discussion? So big objects don't decay due to atmospheric drag huh!)

I looked to refuting your blanket dismissal of the feasibility of the ideas I expressed above. It turns out that the math underlying Orbital Mechanics is far less onerous than I had thought--once you find the right source of practically, rather than theoretically expressed information. What eventually stopped me was the requirement to be an "approved registered user"(*) in order to obtain the basic data (TLEs) with which to construct a simulation. Well that, and the distinct impression that it wouldn't sway you one iota.

Al-Qaeda might nip up there and start throwing them at the US?

There are reasons why using a redundant space shuttle wouldn't be a good idea. None that you broached though. It's mostly to do with its mass. Regularly changing the orbit of so massive a structure, most of which would be redundant for the task, it too costly. However, that doesn't mean that it would make sense to use a to-be-retired-shuttle to put such a project into orbit.

And the Molinya orbit wasn't such a red-herring after all. For two reasons.

• Firstly, a highly elliptical orbit is advantageous for this because it is much cheaper (in fuel) to alter the inclination of a satallite when it is further way from the Earth. Further away means slower velocity, mean less fuel to alter the inclination.
• Secondly, the elliptical orbit takes the deflector across many circular orbits (the ones where most satellites tend to be stationed), and as you transition those circular orbits in the elliptical orbit, the angular velocity of both is the same. Ie. As you transition the path of those pieces of debris in the circular orbits, provided that you are moving in roughly the direction and inclination, the relative velocities will be minimal.

Some data

Where do I start?

I've never said that it is easy to dodge all space debris. What I've repeatedly said is that any individual known piece of space debris is easy to dodge. Which is true. I've also said that dodging an individual piece of debris is easier than removing it. Which is true. I've also said that collecting debris is easier than deorbiting it. Which is true for all but a handful of large pieces. And that handful is, of course, easy to dodge.

Of course this leaves the huge problems of debris you don't know about. It also ignores the scaling issue, which results from the fact that n satellites and m pieces of debris results in nm combinations that you have to keep track of. And you also have the problem that debris can hit debris, creating more debris.

And the Molinya orbit is a red herring if your aim is to arrange for low speed collisions with debris. (Which is what you were proposing it for.) Sure, your orbits intersect, but at the point of intersection your relative velocity is large. If you just want to intersect debris, then the Molinya orbit is not a bad idea. However you have the huge problem that a high speed impact between a solid object and debris is an event that is very, very likely to result in more orbiting debris, not less. If the solid object is a retired space shuttle, then I guarantee that you'll increase debris, not decrease it. While plenty of other objections can be leveled, that one alone is a deal breaker.

That looks like it addresses all of your points. Did I add any information I hadn't already provided? Unfortunately not. If you come up with another reply which is completely addressed by points I've already made repeatedly, I won't bother replying again.
