Astronauts are usually gregarious and quite pleasant people who like to share their experiences of living and working in space. Current International Space Station resident Greg Chamitoff is no different, and he is now ready and waiting to answer any burning questions you may have about human space flight. NASA offers a “Ask the Expert” website for many of its human missions, where the public can submit questions and astronauts or other NASA personnel answer with written and/or audio replies. But the past few space shuttle missions have been so jam-packed with ISS construction activities, there hasn’t been time in the schedule for astronauts to answer any questions from the public. However, Chamitoff will be on board the ISS for a couple of months, and he has some time to answer a few questions. Questions will be transmitted to Greg from Mission Control each week and his answers to a few of them will be available here.


Don’t know what to ask? NASA has a few guidelines:

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.

Check out the archives of past questions answered here. There you can even listen to audio of questions answered by the STS-107 crew of Columbia. They really were a great crew.

NASA also has a few rules about asking questions:

Stay on topic.

No profanity, sexually explicit or discriminatory material.

Basically, be nice. So, ask away!
