The owner of this decommissioned satellite has obtained emergency approvals to move it to a higher orbit to protect other satellites because it's about to explode due to "irreparable thermal damage" to it's batteries.
Well, that's cool. But I'd like to know how they know the batteries are about to explode. Are they just going by a voltage or resistance reading, or something simple like that? Or, is this just a case of operating the batteries out-of-spec, and now they're just being extra-cautious.
