NEW YORK: Wealthy space buffs will have the chance to own three small particles of lunar matter when what Sotheby’s describes as the only known documented “moon rocks” to be legally available for private ownership hit the auction block in November.

Sotheby’s said on Tuesday it expects the fragments, retrieved from the moon by a Soviet space mission in 1970, could fetch between $700,000 to $1 million at the Nov 29 auction in New York.

The pieces — a basalt fragment, similar to most of the Earth’s volcanic rock, and bits of surface debris known as regolith — are being sold by an unidentified private American collector who purchased them in 1993.

Sotheby’s said in a statement they were first sold in 1993 by Nina Ivanovna Koroleva, the widow of former Soviet space programme director Sergei Pavlovich Korolev.

The fragments, ranging in size from about 0.079 inch x 0.079 inch to 0.039 inch x 0.039 inch, were presented to her as a gift on behalf of the Soviet Union in recognition of her late husband’s contributions to the programme.

Sotheby’s said that the particles, encased under glass with a Russian plaque, are both the only known lunar sample to have ever been officially gifted to a private party, and with documented provenance to be available for private ownership.

The particles being sold in November were retrieved in Sept 1970 by Luna-16 which drilled a hole in the surface to a depth of 13.8 inches and extracted a core sample. They are encased under glass below an adjustable lens and labelled —16 [SOIL PARTICLES FROM LUNA-16].”

Tests on similar samples have dated the bits as being as much as 3.4 billion years old.
