The Irish landing stamp badly indicates the moon

The postal services of the Republic of Ireland have apologized for having spelled "the moon" in Irish on its new commemorative stamps celebrating the 50th anniversary of the Apollo landings.

The postal service, known as An Post, launched the stamps last week.

Four astronauts appear on the stamps of Irish origin.

The Irish word for moon is "gealach". But the stamp has accidentally spelled "gaelach", which means "Irish language".

Instead of reading "The 50th Anniversary of the First Landing of the Moon", it now reads "The 50th Anniversary of the First Landing of the Irish".

The mistake has been spotted on social media in recent days.

"If the original Irish text was correct, the transposition of the letters in a later draft was not taken into account during the final proofreading, before the printing and publication of the stamps on 4 last July, "said An Post.

"In the process of designing the latest space exploration stamps, the letters" a "and" e "were transposed into the title in Irish on two of the four stamps."

One position stated that it has made arrangements to ensure that such mistakes do not happen again.

Retired Colonel Cady Coleman, an astronaut with the US Air Force and NASA, launched the stamps.

She is one of four astronauts appearing on the stamps, alongside Neil Armstrong, Michael Collins and Eileen Collins.
