Notified participants of WikiProject Astronomy Which is the correct qualifier to indicate, here and in location of landing (P1158), that a landing is in fact a splashdown (Q1642255)? I tried object of statement has role (P3831) in Apollo 7 (Q188486) (see Q188486#P620 and Q188486#P1158), but better alternatives may be available. Thanks, --Epìdosis 14:17, 1 February 2023 (UTC)

@Epìdosis, I would recommend has characteristic (P1552)splashdown (Q1642255). That said, if location of landing (P1158) is provided, then qualifying either statement with splashdown (Q1642255) seems redundant. It will be clear enough. — Huntster (t @ c) 20:48, 1 February 2023 (UTC)
