Ireland's Moon Landing Stamps

An Post, the postal service of Ireland issued four stamps on July 4. 2019 to celebrate the 50th anniversary of the first Moon landing and U. S. astronauts with Irish ancestry. They acknowledged four American astronauts with Irish ancestry. The 1 Euro stamps are only valid for postage within Ireland.
Neil Armstrong had his roots in County Fermanagh in Ireland and was the first man to set foot on the moon with the Apollo 11 mission. He was previously the command pilot of the Gemini 8 mission in 1966.
Michael Collins had ancestry from Dunmanway, a town in County Cork, Ireland. He was the command module pilot of Apollo 11 and stayed in orbit around the Moon waiting for his companions of Armstrong and Aldrin to return from the lunar surface in July 1969. Collins had previously flown on the Gemini 10 mission in July 1966.
Eileen Collins was the daughter of two Irish immigrants and became the first woman to pilot a Space Shuttle mission when Discovery rendezvoused with the Russian space station Mir in 1995. In 1999 she was the first woman to command a Space Shuttle mission with STS-93. She made two other Space Shuttle missions in 1997 with STS-84 and in 2005 with STS-114.
Catherine `Cady` Coleman who has Irish heritage on both sides of her family undertook space 3 missions. They were on two Space Shuttle missions of STS-73 in 1995 and STS-93 in 1999, both onboard the Columbia Orbiter. Her third mission was onboard the Russian Soyuz TMA-20 spacecraft in 2010 which went to International Space Station when she spent just over 159 days in space.
Interestingly two of the stamps commemorating the Apollo 11 lunar landing featuring Armstrong and Collins had a spelling mistake. It was a misspelling of the Irish word for Moon `Gealach` with the wording `Gaelach` on the stamps.
