GRAIL Names Announced
A class of fourth graders from the Emily Dickinson School in Bozeman, Mont. has helped NASA choose new names for its twin lunar orbiting spacecraft GRAIL-A and --B. The new names -- Ebb and Flow were announced during a media event at NASA headquarters in Washington. The GRAIL mission will enable scientists to better understand the moon's gravitational field as well as what goes on below its surface. The data gathered is expected to increase our knowledge about how Earth and its rocky neighbors in the inner solar system developed into the diverse worlds we see today.
