07/08/24 - NAIF announces the next SPICE training class will take place October
23-25, 2024 on the East Coast of the U.S. at the Maryland Fire and Rescue Institute, University of Maryland,
College Park, MD. The combination of the announcement letter and registration form are available at
WS2024_announcement.html.
Registration is required, the sooner the better but no later than October 1st. Seating is limited and will
be offered in the order in which firm registrations are received.
07/05/24 - The IERS announced there will NOT be a new leap second declared at
midnight on December 31, 2024 (IERS Bulletin C 68).
As a consequence, the current SPICE LSK, naif0012.tls, will remain
current until at least July 01, 2025.
10/16/23 - NAIF announces the deployment of the new WebGeocalc version 2.7.1
on both NAIF's WebGeocalc servers WGC (GUI only)
and WGC2 (GUI and API).
This new version extends the Tangent Point calculation and adds support for
GPS Time both in WGC GUI and in the WGC Web API.
07/01/23 - To comply with the NASA cybersecurity policy,
the anonymous FTP access
to the NAIF server *WAS* terminated on July 1, 2023.
Anybody who used anonymous FTP to download
files from the NAIF server can switch to HTTPS to continue these downloads.
Through HTTPS one can access all SPICE kernels and other SPICE
materials available on the NAIF server starting at
https://naif.jpl.nasa.gov/pub/naif/
For users using wget, the
download help page shows wget options helpful for downloading just directories of interest without unnecessary extra HTML files.
12/29/22 - NAIF announces release of the new SPICE-Enhanced Cosmographia Version 4.2.
This release is focused on a single major change -- upgrading the
Python version used internally and in the program scripting interface
from version 2 to 3, including providing scripting support on Windows
environment where it was not previously available. For full details see
the Cosmographia 4.2
Release Announcement and Installation Notes document.
12/27/22 - NAIF announces the release of updated generic PCKs based on
"Report of the IAU Working Group on Cartographic Coordinates and Rotational Elements: 2015".
Due to extension of the Mars system rotation model in the 2015 Report
that could not be accommodated by earlier SPICE Toolkits, this update
consists of two files:
- pck00011.tpc,
compatible with Toolkit version N0067 or later.
Data in this file, other than orientation data for the Mars system,
are usable by older Toolkits.
- pck00011_n0066.tpc,
compatible with Toolkit version N0066 or earlier.
Phobos orientation data in this file have been modified, and slightly
degraded, to make them usable by older Toolkit versions.
NAIF recommends caution and careful consideration in adopting these new
PCKs, especially for on-going flight projects and well established
analysis activities, as some rotation models in this PCK (e.g. Mercury,
Mars, Neptune, etc.) differ significantly from those provided in the
previous generic PCK (pck00010.tpc).
For complete details about these new
PCK files please refer to their internal comments.
01/10/22 - NAIF announces release of the alpha-test Java Native Interface SPICE
(JNISpice) Toolkits based on the new generic SPICE Toolkit N0067. The capabilities of these
alpha-test JNISpice Tookits have been beefed up, bringing the supported functionality largely
into line with that of CSPICE. For all new and revised capabilities of these Toolkits see
the
Whats's New in N0067 JNISpice document.
01/03/22 - NAIF announces release of the Version N67 Toolkits, with numerous additions and updates including
new high level APIs (tangent point, target separation, azimuth and elevation coordinate conversions), support for
two new frames types ("switch" and "product" frames), large numbers of new C, IDL, and MATLAB wrapper APIs, and
substantial API header documentation improvements. For all new and revised N67 capabilities see the section "Version 67"
of the Whats's New in SPICE Toolkit document.
12/15/20 - After 49 years Chuck Acton has retired from NASA/JPL and the PDS. Boris Semenov has been appointed as the new NAIF Group Supervisor and PDS NAIF Node Manager.
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.
