The Voyager missions transformed most of the large worlds of the solar system from points of light into places to be explored.
One fact dominates the planning for any mission to Uranus or Neptune: They lie far from the sun. A newly released NASA report looks at how we can explore these icy giants.
Only one spacecraft has ever visited Uranus and Neptune: Voyager 2, in the late 1980s. A new NASA report explores the reasons to go back, and what type of mission might take us there.
January 24 was the 30th anniversary of the Voyager flyby of Uranus. Uranian moons have been on my mind ever since New Horizons sent us close-up images of Charon. On the occasion of the anniversary, Ted Stryk produced latest-and-greatest versions of the Voyager views of these worlds.
Now that I have a reasonable-resolution global color view of Pluto, I can drop it into one of my trademark scale image montages, to show you how it fits in with the rest of the similar-sized worlds in the solar system: the major moons and the biggest asteroids.
I've been resisting all urges to speculate on what kinds of geological features are present on Ceres, until now. Finally, Dawn has gotten close enough that the pictures it has returned show geology: bright spots, flat-floored craters, and enigmatic grooves.
Last week's Dawn images of Ceres were just slightly less detailed than Hubble's best. This week's are just slightly better.
The 45th Binghamton Geomorphology Symposium, usually focused on terrestrial studies, shifted this year to planetary science. Ted Stryk gives us an overview.
A few presentation slides with pretty pictures, sized to scale, of the large moons of the solar system.
New plans may make a mission to Uranus affordable within NASA's new, constrained budget.
My guest this was Planetary Society Board vice president Heidi Hammel. We discussed two planets near and dear to our hearts, Neptune and Uranus. What's new on these icy worlds since Voyager 2 passed by, and what are the prospects for their future exploration?
On Thursday at noon PDT / 1900 UTC I'll report on some of my favorite findings from LPSC, and answer your questions about the latest planetary science.
Reports from the March 19 session at the Lunar and Planetary Science Conference covering eight icy moons in the outer solar system: Ganymede, Europa, Dione, Rhea, Mimas, Tethys, Enceladus, and Miranda.
Presenting a newly-processed version of Voyager 2's best images of Uranus' moon Umbriel.
In the first full day of the annual meeting of the Division of Planetary Sciences of the American Astronomical Society, I listened to scientific sessions on icy worlds and on an exoplanet in a four-star system.
I'm preparing a talk for the Pacific Astronomy and Telescope Show here in Pasadena on Sunday afternoon at 1:45. I have spent the morning putting together a slide that I have long wanted to have for presentations.
There's a new orbital mission on the map! As of Friday, the relatively small mass of the asteroid Vesta has finally taken hold of its new artificial satellite, Dawn.
In the past week there have been 25th anniversaries of two events in 1986, one great, one terrible: the closest approach of Voyager 2 to Uranus on January 24, and the explosion of the space shuttle Challenger upon liftoff on January 28.
Here's yet another of the moons of Uranus for you: Ariel, a near-twin in diameter to Umbriel, but apparently with more interesting geology.
Miranda is the one moon of Uranus for which we have very good images from Voyager 2, and that was a stroke of luck, because low-resolution shots of all of Uranus' moons would have told us that it was, geologically speaking, the most dramatic of the five biggest ones.
