Firefox users may also want to download the ActiveX plugin to view captioning on some Windows Media Player videos.

To meet Section 508 Accessibility requirements, NASA.gov captions RealPlayer and QuickTime videos. Captions may not always be available in other formats. The player may not display captions properly in all combinations of media player, browser and operating system. If you need a captioned version of a video, please use this form
to contact us, specifying your problem. We will make every effort to provide you with a captioned video link as soon as possible.
