The Nicaraguan lunar sample displays are two commemorative plaques consisting of small fragments of Moon specimen brought back with the Apollo 11 and Apollo 17 Moon missions and given in the 1970s to the people of Nicaragua by United States President Richard Nixon as goodwill gifts.
At the request of Nixon, NASA had about 250 presentation plaques made following Apollo 11 in 1969. Each included about four rice-sized particles of Moon dust from the mission totaling about 50 mg.[1][2] The Apollo 11 lunar sample display has an acrylic plastic button containing the Moon dust mounted with the recipient's country or state flag that had been to the Moon and back. All 135 countries received the display, as did the 50 states of the United States and the U.S. provinces and the United Nations.[1]
The plaques were given as gifts by Nixon in 1970.[1]
The sample Moon rock collected during the Apollo 17 mission was later named lunar basalt 70017, and dubbed the Goodwill rock.[3] Pieces of the rock weighing about 1.14 grams[2] were placed inside a piece of acrylic lucite, and mounted along with a flag from the country that had flown on Apollo 17 it would be distributed to.[3]
In 1973 Nixon had the plaques sent to 135 countries, and to the United States with its territories, as a goodwill gesture.[3]
The Nicaragua Apollo 11 lunar plaque display was reported stolen,[4][5] but was returned to Nicaragua in 2012.[6]
