Moon Rock Discovery
(N.Z.P.A.-Reuter— Copyright) HOUSTON, May 27. An American space scientist has discovered that a rock brought back from the moon last November is chemically unique and highly radioactive. The lemon-sized rock is thought to be about 4.600,000,000 years old and clearly the oldest rock yet found on the moon; and it is unique in that it has 20 times as much uranium, thorium and potassium as any other lunar rock.
Samples of the rock are now being examined by space agency and university scientists in the United States and Britain.. The new find was announced jointly at the. Manned Spacecraft Centre in Houston and at a meeting in Leningrad of the space research committee of the International Council of Scientific Unions, attended by the United States astronaut, Mr Neil Armstrong, first man on the moon.
