Hello,
Soyuz TM-26 was successfully launched from LC1 of Baykonur
at 15:35:53.822 UTC on Aug 5. It had separated from the 3rd stage
of launcher at 15:44:43.7 UTC. Soyuz' orbital mass after insertion was 7000 kg.
Parameters of insertion orbit were:
Time of 1st orbit asc.node 'crossing' - 15:24:40.959 UTC
Nodal period - 88.6251 min
Inclination - 51.6390 deg
Hmin - 192.9 km
Hmax - 248.8 km
Semimaj. axis - 6594.54 km
Eccentr. - 0.00443
Two impulses were successfully made at 19:15:09 (dV=17.85 m/s, tau=42.3 sec)
and at 20:05:47 UTC (dV=11.49 m/s, tau=27.1 sec). Preliminary 4th orbit
parameters and EFG vector (after 2 impulses) are
Time 19:50:42.931 UTC
