Jonathan’s Space Report No.432 14 August 2000
Shuttle and Stations
——————–
The Progress M1-3 robot cargo ship automatically docked with the
Unity/Zarya/Zvezda International Space Station complex on Aug 8 at 2013
UTC. Docking was to the rear Zvezda port.
Meanwhile, Atlantis has been connected to the STS-106 stack in the
Vehicle Assembly Building. The stack was then moved from high bay 3 to
high bay 2 to test out use of this newly refurbished bay; it will be
rolled out to the launch pad next month in preparation for launch to the
Space Station.
Current Launches
—————-
Contrary to some rumours, the MITA satellite is operating well in orbit
after launch on Jul 15. CHAMP has also begun operations after some
minor problems with star sensors, possibly due to damage during fairing
separation. The MITA satellite is controlled by Telespazio’s Corcolle center
near Roma.
Rumba and Tango, the second pair of Cluster II magnetospheric research
satellites for the European Space Agency, were launched on Aug 9. Here’s
a rundown on the Cluster II maneuvers so far. Apogee raising burn times
are from the ESA web site; there are slight differences in the times
given on different pages of the site. Note that in the highly elliptical
post-burn-4 orbit, the velocity at apogee is very low, which is why it’s
feasible to change the inclination there by 35 degrees. Such large
inclination changes are very rare, except for launches to geostationary
orbit from Baykonur.
2000 Jul 16 1239 Salsa and Samba launched from Baykonur
1251 In 217 x 217 km x 64.8 deg parking orbit

from Fregat stage and from each other.
1630? Fregat at apogee, lowers perigee for deorbit

1243 R and T separate from Fregat in 250? x 18050? km x 64.8 deg
1510 Fregat deorbit burn at apogee, in -157 x 17075 km orbit.
1731 Fregat reenters
2000 Aug 10 0853 Tango burn 1 240 x 23063 km x 64.9
2000 Aug 10 1329 Rumba burn 1, 237 x 23522 km x 64.9
2000 Aug 11 0340 Rumba burn 2, 240 x 33997 km x 64.9
0458 Tango burn 2, 240 x 33997 km x 64.9
2335 Rumba burn 3,
2000 Aug 12 0019 Tango burn 3,
2000 Aug 12 1630? Rumba burn 4
1636? Tango burn 4
2000 Aug 13 1655 Rumba burn 5, 17200 x 120600 km x 90 deg
1658 Tange burn 5. 17200 x 120600 km x 90 deg
By Aug 13 Rumba and Tango were in similar orbits to Salsa and Samba. On
Aug 26 they will begin stationkeeping, maintaining separations from a
few hundred to some thousands of kilometers in a tetrahedral constellation.
