NASA migrated its public‑facing websites to the managed WordPress VIP platform in late 2023, replacing an aging proprietary system.
Why the agency switched
The old content system required specialist knowledge for even simple updates, ran slowly on mobile devices, and struggled with the agency’s 120 million‑plus annual visitors. A modern, open‑source solution promised faster publishing, better accessibility, and a larger pool of developers.
Scope of the migration
NASA moved more than 68 000 pages, thousands of datasets, and roughly 3 000 media collections from the legacy CMS to WordPress. The effort included preserving over 10 000 legacy URLs to avoid broken links for researchers worldwide.
Choosing WordPress over enterprise alternatives
After a year‑long evaluation, NASA’s digital team selected WordPress because the Gutenberg editor offered a low‑learning‑curve author experience and the platform’s massive community provided rapid security patches. The decision also aligned with the agency’s goal of letting scientists publish content without needing to code.
How NASA hardened the platform
NASA runs WordPress on the VIP tier, a cloud‑hosted, FedRAMP‑moderate compliant environment. Security layers include firewalls, edge caching, and continuous integration pipelines that scan code before deployment. Unnecessary plugins were removed, and custom blocks were built to meet scientific visualization needs.
Custom Gutenberg blocks for scientific data
Developers created bespoke blocks that let editors embed live telemetry, image galleries, and interactive charts directly into articles. These blocks pull data from NASA’s existing APIs, keeping the front‑end experience consistent while the back‑end remains on specialized services such as Django or React dashboards.
What remains outside WordPress
The public CMS is only one piece of NASA’s digital ecosystem. Mission‑critical systems, telemetry pipelines, and internal analytics continue to run on purpose‑built platforms. WordPress acts as the connective tissue for public communication, not the control system for spacecraft.
Impact on users and developers
Content creators now publish in minutes rather than days, and the agency benefits from a talent pool that is familiar with WordPress. The migration also signals a broader shift in federal IT toward open‑source solutions that can meet strict security requirements while remaining flexible.
