President Bush is among those excited by the dramatic pictures the Mars "Spirit" rover has been sending home.
Press Secretary Scott McClellan reports the president telephoned NASA chiefs today with his congratulations. According to the spokesman, Bush thanked the entire NASA team for its hard work.
In McClellan's words, the rover "embodies the best of American ingenuity, technical know-how and can-do spirit."
Space enthusiasts have been speculating that Bush might seize on "Spirit's" success to announce a manned mission to Mars or the moon in his upcoming State of the Union speech. But McClellan will say only that Bush remains committed to space exploration.
