- 9/6/19 - NAIF offers a SPICE Newsletter, including information about a job opening with the NAIF Team.
- 9/6/19 - The International Earth Rotation Service has announced there will NOT be a
new leapsecond declared on December 31, 2019. As a consequence, the current SPICE leapseconds kernel, named naif0012.tls or naif0012.tls.pc, will remain in effect until at least July 01, 2020.
- 7/26/19 - NAIF is looking for a person to join the team, principally working on development of the "SPICE 2.0" Toolkit—a re-implementation of the current Toolkit using the C++11 language. More information and the link to apply are found here:
- 5/21/19 - The on-line tutorials have been updated. Also the self-training tutorials and lessons have been updated.
- 2/6/19 - Despite an earlier announcement to the contrary, FTP access to the NAIF server will NOT be shut down on March 22, 2019. We are discussing with JPL's IT people what access means will be allowed in the future given that the federal government is disallowing the use of anonymous FTP.
- 10/01/18 - New NASA cybersecurity policy has required that NAIF immediately make some changes to some of its publicly available web pages. In particular we
were required to add a NASA-mandated header and footer to every web page, even to pages that show directory listings for project and PDS SPICE
data directories. We believe this should have minimal or no effect on our users, but cannot be certain of this. We urge users of the NAIF server to quickly check any automated access to NAIF’s pages.
Some NAIF/SPICE users make use of the Unix wget command to obtain new mission data on a regular basis. You might have to modify your wget
command to reject all additional HTML files that might appear due to this change (using the "--reject 'index.html*'" option). CURL and other data transfer commands may need equivalent changes.
Anonymous FTP termination is CANCELLED UNTIL FURTHER NOTICE Also, NASA is eliminating use of the anonymous ftp protocol for public access from outside of institutional firewalls , such as is currently available on the NAIF server. FTP access to NAIF from outside of the JPL domain will be terminated as of March 22, 2019 at the latest; the https protocol must be used in its place. For example, instead of this FTP link used to access generic kernels:
use this link:
- 09/20/18 - Due to increased security concerns, NASA is eliminating use of the anonymous ftp protocol, such as is used on this server. Information about this change will be provided soon.
- 04/26/18 - NAIF offers A SPICE Update, a PowerPoint presentation summarizing overall SPICE capabilities and then highlighting "newish" items.
- 6/1/17 - Due to equipment failure, NAIF will not be able to provide future Toolkits (version N67 and beyond) for the Sun/Intel Solaris environments.
- 5/11/17 - Regarding CubeSat and Similar Missions
Directions from NASA HQ stipulate that any cubesat or similar mission that would want support from the NAIF Group in deploying and operating SPICE production capabilities, or in providing consultation to SPICE operators or scientists using SPICE, must be paid for by the project, just as is done for larger projects.
Projects are free to implement and operate SPICE on their own without help from NAIF. In this case you'll need people experienced in producing and validating SPICE kernels, and in monitoring the SPICE production pipeline for SPK, CK and SCLK kernels.
Selecting an Ancillary Data System (PDF) provides some commentary that could be useful.
- 4/10/17 - NAIF announces release of the Version N66 Toolkits, with the first formal inclusion of the tesselated plate portion of the Digital Shape Kernel (DSK) as the principle addition. See the above-mentioned newsletter for more detail.
