A system administrator ran a TLS check against apod.nasa.gov and found the site's certificate chain shows a validity window starting in late 2026, issued via Let's Encrypt. The odd future-dated dates have drawn amused attention from tech observers, who note that such entries usually point to certificate misconfiguration or overlapping issuer logs rather than anything nefarious. NASA has not commented on the quirk.
