One for the history books: Stunning Saturn mosaic captured last week by Cassini
I try to be measured in my praise for spacecraft images. Not every photo can be the greatest space image ever. But this enormous mosaic showing the flattened globe of Saturn floating within the complete disk of its rings must surely be counted among the great images of the Cassini mission.
America's Pastime: Planetary Science
Apologies to baseball fans and others for the theme of this week's Planetary Radio preview, which has star player Emily Lakdawalla on deck.
DPS 2013: Tidbits from Titan
I attended a few talks at the Division for Planetary Sciences meeting today that concerned Titan's origin and interesting surface, and then one in the afternoon about the atmosphere.
Gravity assist
With the recent announcement by NASA that the 36 year-old spacecraft Voyager 1 has officially entered interstellar space at a distance from the sun about four times further than Neptune's orbit, and with Voyager 2 not far behind, it seems worthwhile to explore how humans managed to fling objects so far into space.
Europe Will Select Its Next Major Science Mission in November
The European Space Agency will announce two major science missions this November, one of which is likely to be devoted to solar system exploration.
Probing Titan's Atmosphere
By now I hope that everyone has seen some of the spectacular images of the Saturn system (and especially Titan!) from the Cassini-Huygens mission. However, the measurements that often make my heart race are taken by instruments that reveal Titan in ways that our eyes cannot see.
Pretty picture: spectacular Saturn and Titan
A lovely view of the ringed planet and its hazy moon seen from nearly behind them just a few days ago.
Terra Cognita
Pushing back the frontier, and filling in the blank spaces on the map.
Jani Radebaugh, Titan Explorer
Robotic space exploration is human exploration. Meet one of the people behind the machines.
Pretty picture: Looking backward
Here it is: the view from Saturn of our Earthly home, one and a half billion kilometers away. We see Earth and the Moon through a thin veil of faintly blue ice crystals, the outskirts of Saturn's E ring. Earth is just a bright dot -- a bit brighter than the other stars in the image, but no brighter than any planet (like Saturn!) in our own sky.
Return of the Pale Blue Dot
You can be part of a planetwide group photo as Cassini and MESSENGER turn their cameras Earthward on July 19.
Dunes on Tatooine
The fictional world Tatooine, scene of action in the Star Wars movies, is named after a town in Tunisia, where parts of the movies were filmed. The desert backdrops against which the movies were filmed are real terrestrial landscapes, which prove to be perhaps unexpectedly dynamic.
New names for Pluto's little moons Kerberos and Styx; and a new moon for Neptune
Pluto's moons, formerly known as
Scale comparisons of the solar system's major moons
A few presentation slides with pretty pictures, sized to scale, of the large moons of the solar system.
Worlds in Collision
Meet some worlds that were nearly shattered, literally.
One Ocean World Among Many
I'm absolutely floored when I stop to think that our beautiful blue ocean is only one of perhaps a half dozen or more oceans on other worlds in our solar system, and only one of probably millions (or more) oceans on other Earth-like planets in our galaxy. Oceans abound!
The Shores of the Kraken Sea: Great Place Names in the Solar System
Nothing reflects the romance of deep space exploration more than the evocative names of places on the planets and moons.
Mimas and Pandora dance
I've been out of town for a couple of days and am overwhelmed with work and an overflowing email box. So what do I do about that? I ignore what I'm supposed to be doing and play with Cassini raw image data, of course. Here is a
Doing a science on Titan
A tale from the scientific trenches: laboratory work to simulate Titan's rich atmosphere.
