I called the Inflatable Satellite the "IAP" yesterday after I picked up the acronym from another posting. Having since checked the Shuttle WWW pages, I now realise that I should have used "IAE" instead. Bill Bard's latest Seesat-L posting says: >The STS-77 CapCom just informed the STS-77 crew that the tethered >satellite re-entered at about 5:30 AM EDT (0930 UTC) over the Atlantic. If we take this to be a reference to the IAE, then the decay was at May 22.396 - 0.016 day later than my (fortuitous!) prediction yesterday. In fact, it was running 65s late against my final predicted element; the corresponding OIG element is: IAE 1 23872U 96032C 96143.35927604 .33369273 58942-5 57057-2 0 166 2 23872 39.0322 253.9177 0008701 300.5494 59.9587 16.31848780 399 Alan -- Alan Pickup | COSPAR site 2707: 55d53m48.7s N 3d11m51.2s W 156m asl Edinburgh | Home: alan@wingar.demon.co.uk +44 (0)131 477 9144 Scotland | Royal Observatory: A.Pickup@roe.ac.uk +44 (0)131 668 8224
