Did you know there are approximately 19,000 man-made objects orbiting Earth that serve no useful purpose? And those are just the objects having a diameter of 10 centimeters (4 inches) or larger. The estimated population of objects between 1 and 10 cm in diameter is closer to 500,000! Now, think about launching new spacecraft or satellite into space without hitting any of these objects and you can appreciate the kind of work Danielle Margiotta does as an engineer for NASA. Join us at noon EST on Dec. 13, 2011, to ask Danielle questions about the ins and outs of contamination engineering, or how to help a spacecraft and satellites navigate and manage their inevitable encounters with space junk.
