Bill Nye, otherwise known as The Science Guy, inherited his father's fascination with sundials. And so he campaigned to have sundials aboard the Spirit and Opportunity Mars exploration rovers. A look at how a small device reveals big implications as to our place in space.
Bill Nye, scientist, engineer, comedian, author, and inventor, is a man with a mission: to help foster a scientifically literate society and to help people everywhere understand and appreciate the science that makes our world work. Making science entertaining and accessible is something Bill has been doing most of his life. http://www.billnye.com/

NASA's Mars Exploration Rover Mission (MER) is an ongoing robotic space mission involving two rovers, Spirit and Opportunity, exploring the planet Mars. It began in 2003 with the sending of the two rovers—MER-A Spirit and MER-B Opportunity—to explore the Martian surface and geology. http://marsrovers.jpl.nasa.gov/home/index.html
Wake Island Airfield is a military airport located on Wake Island, which is known for the Battle of Wake Island. It is owned by the U.S. Air Force and operated by the Thirteenth Air Force. It serves practically only military purposes within the Wake Island region, yet there is currently little military presence. It can be used for emergency landings of transpacific airliners. http://en.wikipedia.org/wiki/Wake_Island_Airfield
The Attacks on Wake Island and Pearl Harbor were surprise military strikes conducted by the Imperial Japanese Navy against the United States, on the morning of December 7, 1941 (December 8 in Japan). The attack was intended as a preventative action in order to keep the U. S. Pacific Fleet from interfering with military actions the Empire of Japan was planning in Southeast Asia against overseas territories of the United Kingdom, the Netherlands, and the United States. http://www.youtube.com/watch?v=3VqQAf74fsE
