D10 Immediate Deorbit

[nelson61]

Looks like some "confidential" thruster issue requires immediate deorbit of D10.
Serious enough that fuel will remain on board after deorbit is complete.

DIRECTV 10 was carrying 13 transponders at 103cb. Switching them over to DIRECTV 15 should be relatively seamless.

The hydrazine propellant is toxic (small amounts are present in cigarette smoke).

De-orbit, in this case, seems to refer to sending it to the graveyard orbit.

It will be completely seamless, and as a matter of fact, may already have occurred. We have no way of telling for certain which satellite (D10 or D15) is actually transmitting any of the 13 currently active transponders from 103cb. TID 133 (TPN 10) is currently unused.

{EDIT} It was completely seamless. According to the STA filing, "DIRECTV transferred all traffic from DIRECTV 10 to DIRECTV 15 on December 9, 2025,"

Thank you for that heads up. We're working on software changes for the weekly data collection now.
