This is major Tom to Ground Control

Ontem, 22 de Janeiro, "Flight-team engineers for NASA's Mars Exploration Rover Mission were encouraged this morning when Spirit sent a simple radio signal acknowledging that the rover had received a transmission from Earth."
"In North America the black bear was seen by [Samuel] Hearne swimming for hours with widely open mouth, thus catching, like a whale, insects in the water. Even in so extreme a case as this, if the supply of insects were constant, and if better adapted competitors did not already exist in the country, I can see no difficulty in a race of bears being rendered, by natural selection, more and more aquatic in their structure and habits, with larger and larger mouths, till a creature was produced as monstrous as a whale."
