Two identical space probes are on their way to the moon, after launching today (Sept. 10) on NASA’s newest lunar science mission aimed at unlocking mysteries of the moon that are hidden beneath its surface.
Less than two hours after their launch, the twin Grail-A and Grail-B probes were deployed, setting them en route to their lunar destination.
“We are on our way, and early indications show everything is looking good,” said David Lehman, GRAIL project manager at NASA’s Jet Propulsion Laboratory (JPL) in Pasadena, Calif. “We will know more about GRAIL’s status in a few hours, after an opportunity to analyze telemetry and poll our mission controllers.” [Photos: NASA Launches Grail Probes to the Moon]
