Eutelsat said in a statement Thursday that it is investing an apparent solar array anomaly on spacecraft.
“An incident occurred on one of the two solar arrays on the Eutelsat 5 West B satellite, as it approached its orbital test location,” said Marie-Sophie Ecuer, a Eutelsat spokesperson. “An inquiry with Northrop Grumman to investigate the causes of the incident and assess the impact on the performance of the satellite is underway.”
Looks like E5WB has hit something a similar incident happened to Eutelsat W5 suffered in 2008 the loss of one of its solar arrays due to the array's failed drive motor, leading to a switch-off of 4 of the 24 transponders.
We may end up with 3 satellites @ 5 west E5 West A + E5 West B + another satellite.
So all is not lost on the Eutelsat 5 West B satellite as it has a Ku payload of 35 equivalent 36 MHz transponders,
Maybe another satellite can provide support @ 5 west there are a lot of spare empty satellites about :-
