Website Overview
An established domain and managed infrastructure suggest continuity of operations and may support dependable delivery, although neither guarantees service quality.
Domain and Registration
Registered in 1997, this domain has about 28 years of history. That suggests continuity, although ownership and purpose may have changed. Transfer-protection status is present, helping reduce the risk of unauthorized domain transfers. The domain uses .gov, a restricted namespace whose registration normally has eligibility requirements. Registration contact information is publicly available through RDAP.
DNS and Email
Nameservers are provided by Akamai Edge DNS, indicating managed DNS hosting. MX records point to the Microsoft 365 email service. DNSSEC is enabled, allowing validating resolvers to authenticate signed DNS data. No CNAME was found; the observed records resolve directly to addresses. SPF and DMARC are configured. DKIM status is unknown.
TLS and Certificates
The certificate includes the organization field NASA/Goddard Space Flight Center. The certificate issuer is DigiCert Inc, a commercial certificate authority. The certificate uses an RSA 2048-bit public key, offering broad client compatibility. The server supplied a complete certificate chain. The certificate is valid for about 198 days in total, with 48 days remaining.
HTTP and Browser Security
The response lacks these common security headers: CSP, Permissions-Policy. No X-Powered-By header was found, reducing one common source of backend fingerprinting information. No obvious internal addresses or debug information were found in the headers. The Server header contains the custom value gunicorn. Cookie security attributes are unknown.
Technology Stack Analysis
The public page identifies jQuery, Bootstrap without precise versions, leaving fewer clues for version-specific scanning.
Search and Social Sharing
No homepage canonical URL was detected. If duplicate URLs exist, consolidation may be less explicit. Twitter Card metadata is configured. The title has 60 characters, within a common display range. A meta description is present, with 41 characters. The observed directives allow indexing and link following.
