A major point made in the passage is that __________.
Scientist who study earth's moon have two big regrets about the six
Apollo missions that landed a dozen astronauts on the lunar surface
between 1969 and 1972. The biggest regret, of course, is that the
emissions ended so abruptly, with so much of the moon still
unexplored. But researchers also lament that the great triumph of
Apollo led to a popular misconception: because astronauts have
visited the moon, there is no compelling reason to go back. In the
1990s, however, two probes that orbited the moon raised new
questions about Earth's airless satellite. One stunning discovery
was strong evidence of water ice in the perpetually shadowed areas
near the moon's poles. Because scientists believe that comets
deposited water and organic compounds on both Earth and its
moon, well-preserved ice at the lunar poles could yield clues to the
origins of life.
