BETHEL, Maine — A large chunk of rock from Mars is going on public display in Maine.
The Maine Mineral & Gem Museum in Bethel has said the rock -- the largest intact Mars rock on earth -- weighs 32 pounds and measures 9 inches by 10 inches by 6 1/2 inches.
It will be on display starting Wednesday.
The museum said the rock was the result of an asteroid impact on the surface of Mars that ejected material into an Earth-crossing orbit in space.
