Okay I'll try to straighten the satellite/ eclipse mess out.
The satellites are in an eclipse every night right now, from 0345Z -0645Z (roughly). The eclipse is caused by the satellites being in a direct path between Earth and the Sun. The Sun's "noise" level overrides the satellites signal. None of the satellite's transmissions/ pictures would be received on Earth, so they shut the batteries off, by remote control, to conserve battery life.
I Do Not believe the batteries are replaceable. I'll check with FrankP tomorrow and verify that. Once the batteries die the sats float around as space junk. Or fall back to Earth as space junk chunks.
