Pope Leo XIV marked the 56th anniversary of the Apollo 11 mission by visiting the Vatican Observatory at Castel Gandolfo following his midday Angelus address and later speaking with Buzz Aldrin, the last surviving member of the crew that first set foot on the Moon in July 1969. The observatory, founded by Pope Leo XIII in 1891 and tracing its origins to papal studies under Gregory XIII, holds a prestigious collection of meteorites, including fragments from Mars, and continues its mission to serve as a bridge between faith and science. During the call to Buzz Aldrin, the Pope and astronaut together pondered the wonder of the heavens by meditating on Psalm 8, which speaks of the infinite glory of creation alongside its delicate fragility.
