This week's Question: The Philae spacecraft successfully landed on a moving comet last week. Scientists hope to be able to study the material beneath the surface of the solar body, which is traveling through space at 41,000 mph, hundreds of millions of miles away from Earth. Probing the comet’s dust could help researchers determine the origins of life on Earth, and whether comets provided the water that exists in oceans today. Since the material has remained almost unchanged for 4.5 billion years, it is considered by some researchers to be a "cosmic time capsule" that may contain the building blocks of life. What do you think? Will comet missions yield valuable information about the origin of the solar system?
