Hi James,

Well taken, and I agree. Part of their mission was to retrieve lunar
samples, but how imagine meteorites could be found if a team was put
on to the lunar surface with the primary focus of finding meteorites
and ignoring native lunar materials. :)

Maybe Acme H3 Industries, Inc, will have the spare room in their
underground base to lease out space to a meteorite hunting team, and
the necessary scientific equipment to use for the mission (modified
rovers, infrastructure, etc).

Heck, the mining teams might "unearth" (unlune?) buried meteorites
from under layers of regolith.

Best regards,

MikeG
