Praise: NASA opens 2012 with holy GRAIL

Okay, so holy may not be quite so accurate.

The NASA GRAIL (Gravity Recovery and Interior Laboratory) mission is two satellites that are almost in place to explore the interior of the Moon.
PASADENA, Calif. – NASA's Gravity Recovery And Interior Laboratory (GRAIL)-A spacecraft is within 24 hours of its insertion burn that will place it into lunar orbit. At the time the spacecraft crossed the milestone at 1:21 p.m. PST today (4:21 p.m. EST), the spacecraft was 30,758 miles (49,500 kilometers) from the moon.
Launched aboard the same rocket on Sept. 10, 2011, GRAIL-A's mirror twin, GRAIL-B, is also closing the gap between itself and the moon. GRAIL-B is scheduled to perform its lunar orbit insertion burn on New Year's Day (Jan. 1) at 2:05 p.m. PST (5:05 p.m. EST).
Science is a wonderful way to welcome a new year.  Stars and Stripes has more about the launch and what the scientists at NASA hope to learn.

Wishing everyone a year of enjoyable learning, with movement toward health and equality.

Happy 2012
