Most deep-space probes use storable hypergolics (hydrazines + nitrogen tetroxide). Some of the crazy parts of this book actually came true!
(I don't intuitively understand how the JWST has $10 billion precision optics and hypercorrosive oxidizers right next to each other, and nothing bad happens. Engineering baffles me).
