University of Hawaii geologist Linda Martel, who wanted to be an astronaut as a little girl, will pursue her fascination with space in search of meteorites during a seven-week expedition in Antarctica. “It’s like a field trip to the moon and asteroids,” she said. “I picture this as being in a space outpost.” An educational specialist in the Hawaii Institute of Geophysics and Planetology, Martel is scheduled to leave tomorrow to join nine other scientists on this year’s Antarctic Search for Meteorites team. The National Science Foundation, NASA and the Smithsonian Institution sponsor the annual expedition to search for clues to the origins of the solar system, planets and possible life on Mars.
