Ask an Astronaut: Steve "Swanny" Swanson just returned from orbit and will have a chance to answer a few insightful questions from his Instagram audience. There are three ways to ask a question: comment here with your question; share an Instagram picture holding a sign with your question; or upload an Instagram video of you asking your question. Make sure to include hashtag #askAstro so Swanny can see it. Be sure you are following ISS on Instagram. Video answers will be posted on this account and will include the account tag of the person who asked the question.
