The Americans sent a chimp and an Irishman into space,
when the rocket got out of the earth's magnetic field, the chimp undone his seatbelt and opened an envelope which had been left for him.
It said when the rocket has left earths atmosphere set a trajectory of seven degrees an twelve minutes towards the moon, orbit the moon for two days and take accurate photograph of the lunar surface, then set the same trajectory back to earth and land in the Pacific ocean fifty miles south of the Hawaiian islands where you will be picked up by the U.S.S. Nimitz.
The Irishman then opened his envelope which said
Mick don't forget to feed the chimp.
