First movement in apogee in about a month bumping up about 190 km to point just above geostationary altitude. Perigree still moving slowly up, eccentricity increased a little due to the significant increase in apogee.

Epoch (UTC): 4:32:21 AM, Sunday, June 15, 2008
Eccentricity: 0.2819813
Inclination: 019.3037°
Perigee Height: 17,248 km
Apogee Height: 35,806 km
Right Ascension of Ascending Node: 143.1873°
Argument of Perigee: 019.1372°
Revolutions per Day: 01.45443859
Mean Anomaly at Epoch: 052.6207°
Orbit Number at Epoch: 185

Seen a link to posted info about Pentagon ownership of the satellite now.

Apogee steadily increased 27km/day during last 30 days. This would work out to about 2 more years to reach geostationary if it has enough fuel.

Looks like this is credible evidence of the sale.

James; You might want to remove this thread from the stick list. looks like AMC 14 is a dead issue as far as Echostar/Dish are concerned.

If you'll calculate addidional time to change inclination from 19 degree to 0, then perhaps add another 2 years.

Eccentricity and inclination have also been steadily decreasing so everthing comes together.

SES filed a total-loss claim and expects to receive its $151 million share of the settlement by the end of June. EchoStar Corp. of Englewood, Colo., owned a minority stake in AMC-14 and will receive a payment of around $40 million.

I'm sure Echostar would rather have use of the satellite ... but at least it wasn't a total loss.

So what is the government going to do with it?

It would be nice to think they would play with it for a while, get it in a usable orbit, and sell it to someone who needs it. But that's probably too logical. :)

Now that the gov owns it, perhaps a shuttle mission could place it into another orbit??

The physics have not changed. Getting the shuttle and AMC-14 at the same altitude is the first problem. Besides, with the limited number of shuttle launches left I doubt if they would want to spend the time on it.

It wasn't the ownership that was preventing a shuttle rescue. :)

For the cost of a shuttle mission, couldn't one buy several new satellites rather than fixing up orbiting space junk?

Give that person the prize! Even at the cost of a sidebar on a shuttle mission, I bet you'd be able to get a satellite built and launched. And maybe a ground spare to boot. :)

OMG

The odds of getting the shuttle out to AMC-14 are just slightly better than the odds of my Bengals winning a Super Bowl in my life-time.

When the shuttle services the Hubble Telescope it is at the very edge of it's operating envelope... about 400 miles above earth. The Clarke Belt (where the sats live) is about 22,000 miles above earth. Even if AMC 14 was stuck at 10,000 miles the shuttle still couldn't get anywhere near it.

So, any "shuttle rescue" mission is just simply impossible.

Kinetic Force anti-spy satellite ;) The beauty of these things is that the sats own mass is all that's needed.
