Obtaining certificate chain for standards.nasa.gov, one moment while we download the standards.nasa.gov certificate and related intermediate certificates...

Revocation check via OCSP and CRL for standards.nasa.gov failed

Sorry, the request for standards.nasa.gov could not be completed...

We could not load the certificate for standards.nasa.gov, it might not exist or we could not reach the server, complete the TLS handshake, etc.

Check the revocation status for another website

Revoked certificates can't and should not be trusted, these certificate will cause errors like "NET::ERR_CERT_REVOKED" in browsers and expose a security risk.
