ISS Service Module Thruster Test Fails

I totally concur. Thanks for corroboration.

If it is truly an external cover, this sounds like something that might
be repairable with an EVA (earlier reports implied the failure was a
propellant valve, which seems like it would be a lot nastier to work
on). Or for that matter, it might be a sensor failure, or an issue that
could be worked around with different procedures (random speculation:
opening the cover in a different thermal environment or giving the
actuator more current or more time to open.)

They also note that a reboost using only one of the SM main engine is
still possible.

According to Solovyev the cover did not open fully because it was stuck
against the inter-ship comms antenna which was recently installed there
to support ATV docking in 2008. At present there are no plans to do
anything about it.
