While there certainly are NASA civil servants as well as contractors who work at NASA and have used Rosetta Stone, they have not used the software because of their NASA association. Since government agencies such as NASA and the Department of State have many employees who work with colleagues in other countries, many of them need to learn new languages. Some of these individuals may have purchased the software with their own funds, while others may have been reimbursed by the agency, because learning a new language was necessary for their job.
Determine whether learning a new language might help you perform your job better. For instance, if you are NASA scientist, engineer, physician, or astronaut who expects to be working with Russian colleagues in the near future, learning Russian will make you a better asset to the agency.
Ask your supervisor if you may be assigned the task of learning your chosen new language as an official part of your work for several months. If he or she agrees, purchase the Rosetta Stone software wherever it's sold and follow your department's procedures for obtaining reimbursement for your purchase. Together with your supervisor, determine how many hours per week during work you should devote to your language studies. Arrange your schedule in such a way that your language studies do not interfere with your performance of the other tasks of your job.
Determine how much time outside of work you can devote to your language studies, in addition to the time you devote to your studies at work. If you work at the Johnson Space Center in Texas, Ames Research Center in California, at the Goddard Space Center in Maryland or at NASA headquarters in Washington DC, you may have a long commute to and from work. Consider using your commuting time for your language study. Once you've worked out the study plan with your supervisor, open the Rosetta Stone software, insert the instruction disc into your computer, and follow the program as per the schedule that you've planned.
