NASA's $2.5 billion Mars rover sent
back its first signals to mission
control as it was about to enter the
Red Planet's atmosphere in the final
moments of a dramatic touchdown.
"We can confirm that the event is
actually happening," said a member of
mission control at NASA's Jet
Propulsion Laboratory. "We are
receiving heartbeat tones at this time,
things are looking good."
