In November 2014 the Philae lander touched down on 67P. As I tried to imagine what was happening there now, I realized that "there now" doesn't really have much meaning when "there" is 30 light minutes away. And maybe "what's happening" doesn't have much meaning either, given that the region of spacetime outside of one's light cone provides the sort of causal isolation quantum computing engineers would kill for.
In a lapse of character brought on by mental fug I penned a poem
On Everett's Peak
Rosetta, Philae, half an hour away if you're travelling light
Packed with meters, big and small
And a single transistor failure could ruin it all
Cosmic ray, beta decay, a single gamma misplaced
State changed, plan deranged, non-redundant memory defaced
It hasn't happened yet, at mission control, as far as it is known
At mission control, it hasn't happened yet, anytime in this
light cone
It hasn't within, so has it without? Yes or no? Or mu?
Evidence for the putative event is barely to be found
Predictors of the system crash are
light on the ground
It's place in past or future cannot be agreed
No statement about it can be confirmed
Except by our children selves
All of them
In thirty minutes time
