This site is rich in interactive multimedia content implemented using JavaScript and Flash 5. However, great efforts have been made to ensure that the content presented in this site will be accessible to visitors with special needs as described in Section 508 of the ADA. These efforts include such standard practices as providing alt tags for inline images, using client-side rather than server-side image maps, and denoting tables used for formatting purposes only. Tabular presentation of data utilizes scope attributes in denoting row and column relationships.
For visitors who must use browsers that support some level of JavaScript but cannot support at least JavaScript 1.2 and Flash 5, we strongly recommend that the browser be set to disable JavaScript entirely. In the case of browsers that do not have JavaScript enabled, interactive activities will not function. However, those pages containing interactive JavaScript or Flash activities will present alternate text descriptions of what is happening in the activity.
If you should have any difficulties in accessing information on this site, please contact access@mail.arc.nasa.gov, and they will do their best to provide you with the information in an appropriate format.
