Following on from my earlier message, two objects are being tracked in
orbit: 2008-037A/33272 is the satellite, which I assume will be named Cosmos
2441, and 2008-037B/33273 the Soyuz-2 third stage (does this still retain
the old Blok I designaor since it uses the RD-0124 engine rather than the
The initial orbital data for the satellite were 98.33 deg, 93.82 minutes,
196-727 km, but by early this morning Space-Track data were giving the orbit
as 94.06 minutes, 200-746 km. Not sure if this is a real manoeuvre or just
that a preliminary and somewhat inaccurate initial orbit was issued.
Ignoring the two Araks missions, the apogee is the highest that we have seen
in the Soviet/photoreconnaissance satellite programe. I assume that we
will see perigee sigificantly raised soon so that the seven years lifetime
can be attained with relatively few manoeuvres.
And following on from my original posting, I have had a quick look at the
orbital data for the first Resurs-DK. That was launched to a 69.84 deg,
89.88 minutes, 192-347 km orbit on June 15, 2006 and on June 18 manoeuvred
to 94.01 minutes, 356-585 km. Since then there have been no further
manoeuvres - then again,the high orbit might mean that none are called for!
The last orbital data for this morning show the orbit as 93.82 minutes,
