NASA launched two lunar orbiters Saturday morning, despite weather conditions which limited launch windows to one minute.

The orbiters were originally scheduled to take off Thursday.

The unmanned probes are designed to map out the moon's surface in unprecedented detail.

The two probes are nearly identical.

Called GRAIL-A and GRAIL-B, they were launched aboard a single Delta II rocket, in order to save money.

    Grail stands for Gravity Recovery and Interior Laboratory. There is a great deal of info at moon dot mit dot edu. The point is to map the gravity field of the Moon in unprecedented detail and to use that info "to X-ray the Moon from crust to core to reveal the Moon's subsurface structures and, indirectly its thermal history."

    The Moon is Full at 5:27 AM Monday. At 7:00 AM, it is still possible to see the planet Jupiter almost directly overhead and the Dog Star, Sirius, in the southeast about halfway up the sky. Sirius is the brightest celestial object not in our Solar System. This week, the Moon, Jupiter, and Sirius are the last 3 celestial objects lingering as morning twilight supersedes night.

    More wasted millions. Why not plan a trip to Venus to see if they have the QVC there?
