Disastronomy

Disastronomy
noun [U]
/dɪˈzəˈstrɒn.ə.mi/

The concurrent study of both Murphy’s law and the physical universe beyond the Earth's atmosphere. Couple of Disastronomers can often be seen in the wild looking for a large stone to replace a forgotten counterweight, removing a forgotten dust cover after a sequence of dark frames, or falling asleep in the control room after too much Cassoulet.

And yes. We forgot the counterweights.
