Unlike Earth the moon does not have air, food and water, so it would take a lot of effort for humans to live and work there, wrote Raina Huang, a student at Bexley High School in Columbus, Ohio, and finalist in the second annual NASA Lunar Art Contest.

The contest, sponsored by NASA's Langley Research Center, had a total of 147 entrants from 25 states, France, Poland, India and Romania. A panel of 12 reviewers that included professional artists, scientists, engineers and educators evaluated the entries using three criteria: the artist's statement, creativity and artistic expression, and whether the art represented a valid scenario.
