Is it physically possible to have a satellite 1 light-hour from earth take a snapshot in order to ascertain the cause of events like the disappearance of Flight MH370?

Unclear from your question whether you've already thought of this wrinkle, but... how would you tell them where and when to record?  You can't send them a signal, because the signal travels at the speed of light, so then it'll be too late.  This is why information can never travel faster than light (even if some things, like wavefunction collapse, do seem to be instantaneous).  

You'd need an array of satellites recording everywhere with perfect detail... which is essentially just a rebigulation of the existing spysat network.  The recorders being a light-hour away can't help you any more than that.
