ROSAT Reentry

Tracking the orbital decay of ROSAT.
Providing & collating information on getting a visual of its atmospheric re-entry.

Hypothetical : what would happen if an accidental collision (eg UAV etc) destroyed cockpit - no transponders - engines remain powered #MH370

Heads up Adelaide Canberra Brisbane, TACSAT-3 re-entry in next 2 hours, tracking over you in 1 hour (~20:00-20:15 UTC) visible pass too

[Phobos Grunt @PhG_Reentry]

Timed observation invaluable at this stage to confirm orbit: Any available #PhobosGrunt observers within 400km of Greece?

Phobos Grunt re-entry track and visual guide http://t.co/0NWTQFSt Anyone under these #PhobosGrunt tracks (particularly the yellow lines)?

[Phobos Grunt @PhG_Reentry]

Phobos Grunt re-entry will be on one of these tracks http://t.co/pHdwlV87 (showing 2012-01-16 +/- 24hrs) #PhobosGrunt

Phobos Grunt prediction with ±20% drag [flux variations] http://t.co/4wEkARUU Re-entry #PhobosGrunt 17th January 4h UTC ±3½ days ♥

[Phobos Grunt @PhG_Reentry]

Phobos-Grunt predicted re-entry within days of 5th January 2012 http://t.co/DC2ntL0g (if remains consistent) earlier if solar flux increases

[Phobos Grunt @PhG_Reentry]

Phobos-Grunt: around one month to re-entry, within several days of 6th Jan 2012, if configuration & rotation remain consistent #PhobosGrunt
