"Although water retrieval has been attempted, it is not recommended due to the adverse effect that salt water has on avionics, electronics, and structures. This approach was abandoned due to the elevated cost associated with refurbishing salt water damaged components. By avoiding water retrieval, the engines would avoid maintenance that would have resulted from the corrosive nature of the salt water and thereby expedite turnaround time. When considering recovery of reusable systems, salt water is much more severe than returning to land at the launch site."

- varjag 8y agoThis is related to rocket engines, not ballistic descent capsules.
- Teever 8y agoBallistic descent capsules such as the Dragon have rocket engines in them.

- avmich 8y agoTrue. However some capsules have rather small engines, and small available delta-v, so the whole propulsion package can be made, say, replaceable. Soyuz, for example, lands using only about 30 kilograms of hydrogen peroxide to help with control during reentry. Maybe Crew Dragon can evolve to have this subsystem serviceable.
