NASA scientist Peter Jenniskens, second from right, leaders of a group of researchers searching for pieces of a meteorite, goes over the search plan before take off from McClellan Air Park in Sacramento, Calif., Thursday, May 3, 2012. Researchers from NASA and the SETI Institute are using the zeppelin, Eureka for their aerial search in hope of spotting sites where large fragments landed after a meteor exploded in the atmosphere over the Sierra Nevada in late April.
