Raytheon Antarctic Job/Career Fairs

I'm looking into applying for a job in Antarctica through Raytheon and had a question about their job fairs. The closest upcoming fair close to me is in Chicago but the only info on it is that it is a tech/career fair. Is there a specific Raytheon Antarctic job fair held somewhere in the US at a certain time, or is there a booth at every fair across the country? Any help anyone could give would be much appreciated.
