Hello, Spirit: Mars landing successful

NASA's "Spirit" Exploration Rover appears to have arrived safely on the red planet this evening. The robot geologist touched down, sending back a simple message of its landing.
"...Tonight another first was made, for the first time in human history ... we have an interplanetary communications network. We went from the rover, to Odyssey [Mars satellite] to Earth to the Deep Space Network. So we've now established a communications satellite system over another planet for the first time in history..." -- Dr. Ed Weller, NASA
