The space shuttle Endeavour began its 2-mph crawl through streets of Los Angeles at about 2 a.m. Friday. A retired laser scientist uses Endeavour's terrestrial crawl as a teaching moment for Los Angeles school children.
The blue moon Friday is on the same day of a private memorial service for Neil Armstrong, the first man to walk on the moon. A blue moon occurs when there's a second full moon in one calendar month. It won't happen again until July 2015.
