Yes. The earliest elset that is clearly for Shenzhou 4 is/was the first one posted under the guise of the C object as: Shenzhou 4 337 x 331 km 1 27630U 02061C 02364.32978705 .00101531 00000-0 55473-3 0 19 2 27630 42.4080 336.0847 0004797 163.8920 321.6647 15.78791273 19 There is no evidence that this has manoeuvred since. >- All the A elsets up to 02364.70568348 and all the B elsets since then >denote a separate object. But what is it? The rocket body? Yes, the rocket body. The first elset for this (as object A) is/was: Shenzhou 4 r 8.0 3.0 0.0 4.5 d 20 332 x 198 km 1 27630U 02061A 02363.99130504 -.00002620 82868-5 00000-0 0 14 2 27630 42.4085 338.1747 0100490 131.4080 229.5479 16.03477566 55 > >If this is what you mean, then it is true what I wrote - that we do not >have any element sets for the real Shenzhou-4 spacecraft in its initial >orbit (before the manoeuvre)! Am I right? > The only other elsets were those orphan ones I reported in my previous post, the first of which... 1 27631U 02061B 02363.99063452 -.00002648 83756-5 00000-0 0 19 2 27631 42.4166 338.1817 0096007 122.0244 238.9998 16.07463202 45 ...has an epoch only 58 seconds earlier than the first elset for the rocket (above). If I interpret Ted Molczan's latest SeeSat-L posting correctly, he suggests that this is the earliest elset for Shenzhou 4 itself and that the other three orphans represent tracking or analyses mishaps. There were no prior elsets for anything from this launch.
