- 12/13/18 - New capabilities have been added to the WebGeocalc tool, including a RESTful interface provided on a new instance of a WebGeocalc server. Read the WebGeocalc announcement for details.
- 12/11/18 - Next SPICE Training Class
The next beginner's SPICE training class will be held in the Pasadena, California area this coming Spring. The current dates being considered are:
April 9 - 11 (not very likely)
May 29 - 31
June 4 - 6
June 12 - 14
An announcement will be made here and using the "spice_announce" system once firm dates and the venue (a hotel) have been selected.
- 12/06/18 - An upgrade to the WebGeocalc (WGC) server did not occur on 12/3 as planned, but is expected to occur very soon. WGC will not be available during this time.
- 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.
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.
- 04/25/18 - Andrew Annex announces the release of SpiceyPy 2.1.1, a user-produced interface to cspice. https://github.com/AndrewAnnex/SpiceyPy
(NAIF is pleased to see SPICE users produce and freely offer SPICE-related products and services. However, NAIF, Caltech/JPL and NASA cannot endorse or in any way warrant such third-party SPICE related products or services. Any potential user of SpiceyPy must make her/his own determination as to the efficacy of SpiceyPy for any particular endeavor.)
- 1/26/18 - The International Earth Rotation Service (IERS) has announced there will not be a new leapsecond added on June 30, 2018. As a consequnece, the currently offered SPICE leapseconds kernels (LSK), naif0012.tls for Linux and Mac, and naif0012.tls.pc for Windows, will remain in effect until at least the end of December, 2018.
- 01/09/18 - NAIF offers a SPICE newsletter.
- 11/03/17 - All of the on-line tutorials, the programming lessons, and the self-training packages (class tutorials and programming lessons) have been updated.
- 8/9/17 - N0066 Toolkit DSK Bug. A bug, not very likely to be encountered, exists in the DSK subsystem of the N0066 Toolkits. Read the announcement (PDF) for details.
- 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.
- 01/27/17 - Due to new NASA IT security requirements, on January 27, 2017 the NAIF
HTTP server was reconfigured to redirect all http: requests to https:.
While this change is transparent for access via most Web browsers, it
might have affected access via curl and wget. Transfers initiated with
recent versions of wget and of curl (with the -L option) should work but
those done with older versions of both tools might fail. We recommend
that all users who automatically copy kernels and toolkit packages from
the NAIF server via HTTP using wget, curl, and similar utilities verify
that they still do it successfully with this new server configuration.
