Many past shuttle and station crews have answered questions from the web. You can take a look at those archives at http://spaceflight.nasa.gov/feedback/expert/index.html.

From those past missions and crews, here are a few hints that may make it more likely that your question is one that is answered:

• Try to avoid asking a question that has been answered often on previous missions.
• Normally the questions most often answered are those more specific to the current crew and mission.
• Do your homework and review information about the station and current activities when you compose your question.

However, all questions are welcome.
