According to NASA Watch -- about which I know not much -- there are rumors that deorbiting of GRO is being considered (story marked "new" and dated Jan. 13): http://www2.nasawatch.com/nasa/watch.html I would have sworn that there was a link to that from Space Today, but I can't find one now. I don't read NASA Watch, so I was led to it yesterday from some other site. Anyway, out of curiosity I got recent GRO elements. If I'm reading them right, inclination is decreasing, eccentricity is INcreasing, and mean motion is increasing. Increasing drag is normal, but I wonder if the magnitude of the change is natural. Do these add up to a natural evolution of GRO's orbit? Anything unusual?

I watched a "sucker hole" close up just a few minutes before the best part of the ETS 6 pass. Also didn't get to see a good GRO pass.
