10018 is a rounded, dark grey, regolith breccia (weight 213 grams) similar in composition to iron-rich lunar soil samples. It has a glassy matrix in which are found basalt fragments, anorthosite fragments (pieces of lunar highland rocks), minerals, glass-welded aggregates (agglutinate), and a range of different types of glass fragments. Overall the rock appears to be a high glass breccia with minor crystalline inclusions.

The Apollo 11 samples create an iconic collection since they were the first rocks collected by humankind that were returned to Earth from another solar system body. The Apollo 11 team collected and returned 22 kg of rock and soil samples.
Apollo 11 launched from Cape Kennedy on 16 July 1969. An estimated 530 million people watched Armstrong's televised image and heard his voice describe the event as he took "...one small step for a man, one giant leap for mankind" on 20 July 1969.
