NASA's latest rover, this particular one the size of an automobile, successfully landed on Mars late into the evening Mountian time. Curiosity is safely on the surface and already feeding data back to Earth.
If all goes according to plan, the Mars Science Laboratory, nicknamed Curiosity, will land gently on Mars at 10:31 PDT Sunday night. The rover's entry, descent and landing will last for a total of seven minutes. During that time, the rover must slow down from 13,000 mph to a dead-stop touchdown on the surface of Mars.
