CAPE CANAVERAL
(Reuters) - When scientists selected a stone to test the laser robot on Mars
Curiosity, expected to enclose the same raw materials as the stones found in
other areas of the Red Planet, but in its place realized that it was more
similar to rocks found on Earth.
The stone was
chemically more like an unusual rock type found on oceanic islands like Hawaii
and Santa Elena, and in continental areas with cracks as the Rio Grande, which
stretches from Colorado to Chihuahua, Mexico.
