Editor's note: the following was sent out to the Change.gov email list today - I checked and there a half a dozen or so space-related questions already posted.
"Dear Friend: We recently launched a new feature on Change.gov called Open for Questions. Thousands of you responded, asking 10,000 questions and voting nearly a million times on questions from others. Now that we've answered some of the most popular ones from the last round, we are open for questions again. Ask whatever you like, and vote up or down on the other questions to let us know which ones you most want the Transition to answer. Get started now at http://change.gov/openforquestions. We're looking forward to learning about what you want to know. Thanks, John D. Podesta, Co-Chair, Obama-Biden Transition Project"
