Jules Verne Voyager: What's New

16 Apr 2012 If Voyager had been working on your browser and now it's not — especially if you are using Firefox — please update your Java plug-in. (Firefox may have disabled your current Java plug-in without informing you.)

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:

Guide to SDO Data Analysis
A Comparison between Global Solar Magnetohydrodynamic and Potential Field Source Surface Model Results, Riley et al., Astro. Jour., 653:1510-1516, 2006
A Comparison of Solar Open Field Regions Found by Type III Radio Bursts and the Potential Field Source Surface Model, Nitta and DeRosa, Astro. Jour., 673, doi:10.1086/527548, 2008

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 and accessing an external link will open a new browser page

14 Jan 2011 The long-standing bug where the index map, which is created using the [Index] button or the i=1 option, was not exactly 80% of the specified width (as claimed on Solar System Portal: How to do your own comparative planetology images), is now fixed. This will allow for much easier creation of scale orthographic map images to compare different worlds.

9 Jan 2011 Earth and EarthScope: have been updated with events listed in the NEIC earthquake catalog from 1961 through to the PDE-Q solutions at the end of 2010: over 691000 events.

4 Jan 2011 Addition of new [Moment Tensors] option and update of the dataset for the [Focal Mechanisms] option of Earth and EarthScope, now showing all available CMTs through the end of 2010. The display of both is now ordered by depth so the deeper mechanisms are plotted first so that the shallower mechanisms are "on top" (as one might expect with a plan view).

22 Dec 2010 Update to Saturn's major inner moons Mimas, Enceladus, Tethys, Dione, and Rhea. These include recent enhanced-color mosaics, PIA13423, for each of the these five moons made by Space Science Institute and the Lunar and Planetary Institute showing subtle compositional variations on their surfaces.

1 Nov 2010 Addition to Jupiter of New Horizons/LORRI mid- and central-latitude mosaic by JHU/APL.

29 Oct 2010 New PaleoEarth edition, using datasets kindly provided by Dr. Ron Blakey, Northern Arizona University.

22 Oct 2010 Update to Phobos and Deimos; many thanks to Dr. Phil Stooke for the use of his 2010 mosaic map images of these moons.

14 Oct 2010 Update to Pluto and addition of Pluto's moon Charon. (These processed mosaic images will probably be the best available until the New Horizons spacecraft reaches the Pluto-Charon system, closest approach 14 July 2015.)

17 Jun 2010 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.

17 May 2010 A major update to the datasets of the jovian and saturian moons has been completed.

29 Jan 2010 Javascript code for detection of browser popup blocking has been added. Blocking popups from jules.unavco.org prevents use of the Voyager [pop-up:] menu options. (Note: the [pop-up:] menu was previously called [URL:].)

27 Jan 2010 update of Mercury to include the latest from Messenger flybys (14 Jan 2008, 6 Oct 2008, 29 Sep 2009); addition of Uranus (with moons Ariel, Umbriel, Titania, Oberon, and Miranda) and Neptune (with moon Triton and minor moon Proteus); addition of trans-neptunian object (formerly a planet) Pluto; and addition of minor moons Amalthea and Janus. Also, all worlds now have a Wikipedia link in their [pop-up:] menu — click on the [Wikipedia] menu option.
