Katastrophe and Desaster can both describe a completely unsuccessful process or an event with serious consequences. Katastrophe often sounds like an emotional judgment about a failed performance, while Desaster more strongly identifies the specific complete failure. Both words are possible in such sentences, but the nuance is different.
