31 Mar 2016     Ceres was updated with PIA20354 — a natural color Dawn mosaic. Vesta was updated with PIA16186 — a hydrated mineral map — and PIA17475 — a rock properites map.
In addition, all worlds were updated with the latest feature names adopted by the International Astronomical Union (see IAU Gazetteer for more information).

2 Oct 2015     Ceres was updated with PIA19977 — an enhanced color Dawn mosaic using infrared (920 nm), red (750 nm) and blue (440 nm) spectral filter images — and updated with the latest feature names adopted by the International Astronomical Union (see IAU Gazetteer for more information). Also, SHA-1 certificates will be deprecated in 2016, so the Voyager applet was updated with an SHA-2 code signing certificate.

25 Sep 2015     The latest mosaic from the New Horizons team for Pluto: combining LORRI (LOng-Range Reconnaissance Imager) images with those from the on-board Ralph telescope, using both visible light imaging from MVIC (Multispectral Visible Imaging Camera) and near-infrared imaging from LEISA (Linear Etalon Imaging Spectral Array) to produce an "enhanced, extended" color image.

24 Sep 2015     Last year in July the Voyager applet started being bundled with a signed UNAVCO security certificate as needed for Java 7 security updates. The old certificate was due to expire in mid-Nov 2015. UNAVCO has obtained a new security certificate which is valid until the fall of 2018 and this is now bundled with the applet.

17 Sep 2015     An updated set of all feature names adopted by the International Astronomical Union for worlds supported on Voyager, available through the Gazetteer of Planetary Nomenclature, are now avaiable via the [Features:] menu, which includes the addition of the first 18 officially named craters on Ceres and a scarp (or rupes) on Enceladus. The locations of 100 jets or geysers in the southern polar terrain of Enceladus are now shown based on the coordinates given in: How the geysers, tidal stresses, and thermal emission across the south polar terrain of Enceladus are related, Porco et al., Astronomical Journal, 149, No. 45, 1-24, 2014, doi:10.1088/0004-6256/148/3/45.

31 Jul 2015     In the first of what will certainly be many updates from the New Horizons team, there are now global mosaics, using data from the LORRI (LOng-Range Reconnaissance Imager) instrument onboard New Horizons, for Pluto and Charon. from the July 2015 flyby of the system.

14 Apr 2015     Update to Ceres with Dawn PIA19063 mosaic — an enhanced color image of the middle latitudes (using a blue filter at 440 nm, green filter at 550 nm, and infrared at 920 nm (although the color enhancement is reversed so that blue data is shown in red and infrared data is shown in blue) — and an earlier set of lower resolution infrared images taken at the Keck II Observatory (in Sep 2002, using K-band filter at 2124 nm, H-band filter at 1633 nm, and J-band filter at 1248 nm).

1 Apr 2015     Direct from the asteroid belt: Vesta and Ceres based on datasets from the Dawn mission, currently in orbit about Ceres, and some earlier datasets from the Hubble Space Telescope.

26 Mar 2015     Saturn's Mimas, Enceladus, Tethys, Dione, Rhea, and Iapetus were updated with mosaics using PIA18437, PIA18435, PIA18439, PIA18434, PIA18438, and PIA18436, respectively, all from the Cassini NASA/JPL-Caltech/Space Science Institute imaging team from the Nov 2014 enhanced color mosaics, extending into the ultraviolet and infrared ranges. These mosaics bring out the brightness asymmetry in the leading and trailing hemispheres, especially for Tethys, Dione, Rhea, and Iapetus; the asymmetry in the first three is due to brightening on the leading hemispheres from icy dust accumulating from Saturn's E-ring which is formed from ice particles that were ejected from Enceladus' southern polar region and darkening on the trailing hemispheres probably due to surface alteration from magnetospheric particles and radiation.

24 Mar 2015     An updated set of all feature names adopted by the International Astronomical Union for worlds supported on Voyager, available through the Gazetteer of Planetary Nomenclature, are now avaiable via the [Features:] menu. This includes the addition of six paterae on Ganymede and 15 sinus ("bays") and three freta ("straits") — smaller features of the probable hydrocarbon lakes — on Titan. (See IAU Gazetteer for more information.)

13 Nov 2014     Saturn's Mimas, Enceladus, Tethys, Dione, and Rhea were updated with mosaics using PIA14926, PIA14937, PIA14931, PIA14914, and PIA14928, respectively, all from the Cassini NASA/JPL-Caltech/Space Science Institute imaging team.

10 Oct 2014     The datasets for the [Focal Mechanisms] and [Moment Tensors] options of Earth and EarthScope have been updated, now showing all available Harvard CMTs through the end of Sept 2014: now over 41000 events globally.

9 Oct 2014     Earth and EarthScope have been updated with events listed in the NEIC earthquake catalog from 1961 through to the end of Sept 2014: over showing over 912000 events.

6 Oct 2014     Earth and EarthScope have been updated with the current list of volcanoes and sites of volcanic activity listed at the Smithsonian Global Volcanism Program. The dataset being displayed has 1561 sites of Holocene activity.

3 Oct 2014     Mercury has been updated with two new mosaics from the Messenger MDIS orbiter phase, by NASA, Johns Hopkins University Applied Physics Laboratory, Carnegie Institution of Washington. These mosaics are the 8-color mosaic with resolution in some areas down to 665 m per pixel and the enhanced color mosaic, released 8 Mar 2013.

25 Sep 2014     Epimetheus has been added, starting with a 1999 mosaic from the Voyager flyby images created Dr. Phil Stooke (University of Western Ontario). (See Dr. Stooke's Small World Atlas 2000 for more information.)

24 Sep 2014     Triton has been updated with a new color global mosaic (21 Aug 2014) created by Dr. Paul Schenk (Lunar and Planetary Institute, Houston, Texas) — which includes color correction from the original Voyager 2 images from orange, green and blue filters — as part of a prequel to the upcoming New Horizons flyby of Pluto in July 2015. (See Icy Moons: Triton for more information.)

The Voyager applet — has been updated so that it should be more consistent with Java running on Mac OSX platforms in comparison to Windows and Linux.

A new update was done of all feature names adopted by the International Astronomical Union for worlds supported on Voyager, available through the Gazetteer of Planetary Nomenclature, avaiable via the [Features:] menu. (See IAU Gazetteer for more information.)

12 Jul 2014     The Voyager applet — needed for launching any world edition — is now bundled in a .jar with a valid UNAVCO security certificate and a manifest and should now be compatible with Java 7 security updates. The .jar file should load the applet and allow Voyager to work properly under Java 6 as well. (The current configuraton has been tested on Windows and Macs with various operating system releases and various browsers, but just so you know, the situation is not simple. For a reasonably complete overview of what we've been battling, see e.g. Java Tester - What version of Java are you using? For example for Mac OSX, Oracle is now providing Java 7, but only 64-bit and only for OSX 10.7.3 or later, so these builds of Java 7 will not work on Chrome which is only 32-bit at this time.)

11 Jun 2014     GEM_GSRM has been updated to the 1 Mar 2014 (version 2.1) release.

3 Jul 2013     An updated set of all feature names adopted by the International Astronomical Union for worlds supported on Voyager, available through the Gazetteer of Planetary Nomenclature, are now avaiable via the [Features:] menu. (See IAU Gazetteer for more information.)

2 Jul 2013     Titan has been updated with globally-splined topography based on Cassini radar swath height measurements, 2004—2011; PIA16848 and PIA16849 by NASA/JPL-Caltech/ASI/JHUAPL/Cornell/Weizmann.

28 Jun 2013     The Voyager edition of Earth has been updated to include NASA/NOAA Suomi NPP VIIRS datasets showing nightlights — showing most human population centers and other human activiy — and Normalized Difference Vegetation Index (NDVI) — showing our planet's vegetation.

21 Jun 2013     A new, updated "Global Strain Rate Map" version for Earth, developed in cooperation with the University of Nevada at Reno for the Global Earthquake Model (GEM) collaboration: GEM GSRM. (part of a GSRM presentation by Corne Kreemer at the GEM Semi-Annual Meeting, 24-27 June 2013, in Pavia, Italy) Note: This is an updated version of the original ILP GSRM.

17 May 2013     On 8 May 2013 the USGS disabled their old web site for the latest earthquake PDE solutions and switched over to a new web site and interface. We're now pulling their CSV file for the last 7 days, magnitude 2.5 or higher.

31 May 2012     An updated set of all feature names adopted by the International Astronomical Union for worlds supported on Voyager, available through the Gazetteer of Planetary Nomenclature, are now avaiable via the [Features:] menu. As well as updating all previous IAU named groups, this adds four feature types (terra, lacuna, mons, unda) on Titan, two (catena — crater chains — and fossa) on Rhea, one (catena) on Mimas, and two (regio and planatia) on Phobos. (See IAU Gazetteer for more information.)

25 May 2012     Due to a new NASA policy to restrict cross-domain data-sharing (due to a Cross-Site Scripting and Cross-Site Request Forgery security risk), the Solar Dynamics Observatory web site recently started to not allow our Sun tool or others like it to directly load SDO images from their site. The workaround is to use http access to get the images and store them locally on our servers, and then have the tool use our local copies. We are now back to an operational status.

24 May 2012     Titan has been updated with Cassini SAR mosaics, both with (up to T71) and without (up to T77) Cassini ISS reference, by Jason Perry, Lunar and Planetary Laboratory. The actual SAR images (available on Perry's Titan RADAR SAR Swaths site) are higher resolution, but these mosaics serve as a nice global reference and have resolution down to about 1 km, for example, see part of the northern lake region of Titan.

16 Apr 2012     If Voyager had been working on your browser and now it's not — especially if you are using Firefox (Firefox may have disabled your current Java plug-in without informing you) — please update to a Java version 6 plug-in — but please don't use any Java version 7 yet!

27 Mar 2012     Titania has been updated with Steve Alber's Science on a Sphere Oct 2011 mosaic which includes surface detail from the nightside of Titania, from processing by Ted Stryk (similar to that done for Ariel).

26 Mar 2012     Enceladus has been updated with approximate positions of the strongest ice particle jets near its southern pole.

9 Mar 2012     A long-overdue update for the Moon has been started, beginning with a Lunar Reconnaissance Orbiter (LRO) mosaic and topographic model, by NASA and the Arizona State University.

8 Mar 2012     Titan has been updated with the PIA14908 Cassini/ISS mosaic, released Apr 2011, by NASA, JPL-Caltech, and the Space Science Institute. This is an update of the PIA11149 mosaic, released Feb 2009.

7 Mar 2012     Mercury has been updated with two new mosaics from the Messenger MDIS orbiter phase, released 8 Sep 2011 and 28 Oct 2011 by NASA, Johns Hopkins University Applied Physics Laboratory, Carnegie Institution of Washington. The MDIS 2 Sep 2011 mosaic, though globablly incomplete, has resolution in some areas down to 250 m per pixel; some fill-in with Mariner 10 flyby images has been used. The 28 Oct 2011 mosaic uses almost entirely Messenger MDIS data and is more than 99.9% globally complete.

6 Oct 2011     The landing site of the Cassini-Huygens probe on Titan was adjusted by a few ten's of kilometers.

5 Aug 2011     Update to Saturn's major inner moons Tethys, Dione, and Rhea, plus some menu cleanup on the others.

17 Mar 2011     To commemorate the 400th anniversary of scholarly telescopic observations of sunspots — 9 Mar 1611 — (ok, we missed by a few days) started by Johannes Fabricius in Holland, and to include a voyaging method to the largest body in the Solar System, here's a new type of interface for the Sun. This interface uses a SWF file, so the Flash browser plug-in is required, and it imports the latest set of images from the Goddard Space Flight Center Solar Dynamics Observatory web site. The SDO satellite was launched 11 Feb 2010 and gives us an unprecedented view of nearly continuous observations of the Sun. Until we have a more complete documentation for this special voyaging project, here are some links that should help:

Thanks to Andy Gorman here at UNAVCO for finding some spare cycles to develop this new interface with me.

9 Feb 2011     Update of PIA12803 image for Rhea which corrects earlier mapping discontinuities at 180° longitude; mosaic kindly provided by Thomas Roatsch at DLR.

31 Jan 2011     Roll out of redesign of the Voyager site:

  • consistent branding with UNAVCO logo and link at top of each page
  • wider page format
  • new default width of Voyager maps are now at 900 pixels (instead of 720 pixels), which results in map images having 56% more area (and requires about 56% more time to create) from earlier equivalent content
  • user ID of Voyager map sessions now include the user's remote port number, to differentiate separate user sessions coming from NATed IP addresses (as is commonly used in schools, colleges, universities, and so on)
  • external links outside of UNAVCO domain are marked with indicator for external link and accessing an external link will open a new browser page
