Everyone welcome here.

Our commitment

We aim to meet the Web Content Accessibility Guidelines (WCAG) 2.1 at Level AA. In practice that means readable contrast, text that resizes, headings and landmarks in a sensible order, labels on every form field, descriptions for meaningful images, tap targets large enough to use on a phone, and every part of the site reachable with a keyboard.

Display settings you can turn on

The Accessibility button at the bottom of every page lets you choose larger text, high contrast, reduced motion, and an easier-reading style with plainer letters and underlined links. Nothing is on unless you turn it on, and your choices are remembered on your own device only — we do not store them or link them to you.

Known limitations

• Some mission photographs are still being described; captions and descriptions are being written as the gallery is completed.
• Videos shared from social media are hosted elsewhere, so captions depend on the original post.
• Pages that link to outside services — giving, mailing lists, merchandise — are not under our control, though we choose accessible providers where we can.

Tell us about a barrier

If any part of this site is hard to use, please tell us what page you were on and what happened. We reply within two to three business days and will help you get the information another way — by email, phone or in person — while we fix the page.
