[meteorite-list] Kalahari 009 - biggest lunar meteorite?

[Adam Hupe]

Hi Mike and List Members,

An interesting fact about NWA 5000 is that it actually weighed more than the claimed weight of Kalahari 009 at one time.

Let me explain:

We weighed the main mass and liberated portion right after it was cut and it actually gained a lot of weight. The reason being is that the gabbro, unique to this lunaite, actually absorbed the chemical/mineral free coolant during cutting.  The porosity is amazing.  The only truly accurate way to measure the weight is after a piece is sucked to the dryness of space in a vacuum chamber.  The certified weight was before any cutting took place and an accurate casting was taken.


Best Regards,

Adam
