This 15c Cook Islands postage stamp, originally featuring a delicate frangipani flower design and the greeting Kia Orana, was later overprinted to honor the Apollo 13 astronauts. The overprint reads: “Apollo 13 Astronauts – Te Atua to Tatou Irinakianga” (God is our Trust), commemorating the safe return of the crew after their near-disastrous lunar mission in April 1970. The issue reflects international solidarity and admiration for the astronauts’ courage and survival. Collectors value this stamp both as part of the Cook Islands definitive floral series and as a topical item on space exploration.
