NAIF announces that the anonymous FTP access to the NAIF server will be 
terminated on July 1, 2023 in order to comply with the NASA 
cybersecurity policy.

NAIF urges anybody who currently uses anonymous FTP to download files 
from the NAIF server to switch to HTTPS.

Through HTTPS one can access all SPICE kernels and other SPICE materials 
available on the NAIF server starting at top link

For users using wget, the download help page

without unnecessary extra HTML files.
