What I mean by lithocapture is an orbital transfer maneuver used to reduce the velocity of a spacecraft from a hyperbolic trajectory to an elliptical orbit around the targeted celestial body where the periapsis of the hyperbolic trajectory just barely contacts the surface of the celestial body. The sliding impact would reduce orbital energy putting the spacecraft into an elliptical orbit, periapsis would then be raised above the surface by traditional means.
Is this strategy something that has ever been seriously considered by the spaceflight community? Or is it to crazy/unpredictable to ever have serious consideration? If it has been considered, are there in designs for how it would be accomplished?
