Proof for liquids on Titan
A press release from the Cassini VIMS team today is titled
Danes on Mars
I was delighted to receive an email from Morten Bo Madsen, who I knew from the Mars Exploration Rover mission as
Welcome to the Solar System, Makemake
The trans-Neptunian object formerly known as 2005 FY9 now has a name:
More things to see in the amazing HiRISE image of Phoenix' descent
I have posted several times about the amazing photo captured by HiRISE of Phoenix under its parachute as it descended. There have been two common questions I've received about the photo: was there any color data taken, and what more can I tell you about how hard it was to take the photo? I've got answers to both questions for you today.
Opportunity route map update
Eduardo Tesheiner was kind enough to send me an updated version of his route map for Opportunity so we can get a sense of just how close the rover is getting to Cape Verde.
Beautiful mosaic of the Voyager mountains
One of my favorite amateur image magicians, Gordan Ugarkovic continues to play around with the amazing data recently released by the Cassini mission, covering the Iapetus encounter of last September. Here's a lovely mosaic he just put together of the Voyager Mountains.
MESSENGER Scientists 'Astonished' to Find Water in Mercury's Thin Atmosphere
As MESSENGER flew past the night side of Mercury in January, its Fast Imaging Plasma Spectrometer (FIPS) scooped up ions from an atmosphere so tenuous that it's usually called an
Updates on the 2007 Shoemaker NEO Grant Recipients (27 June 2008)
Amateur astronomers play a critical role in retiring the risk of impact from near-Earth objects. When the Shoemaker NEO Grant program began in 1997, the focus was on finding previously undiscovered objects one kilometer in diameter and larger. Thanks to professional NEO survey programs like LINEAR (the Lincoln Near-Earth Asteroid Research program run by MIT’s Lincoln Laboratories) and the Catalina Sky Survey (run from the University of Arizona’s Lunar and Planetary Laboratory), the goal of discovering the vast majority of large NEOs is within reach, and the focus of the Shoemaker NEO Grant Program has shifted to astrometric follow-up and physical studies.
Yep, it's ice!
The Phoenix mission confirmed it this morning: the disappearing act pulled by those chunks of bright material in the Dodo trench pretty much nails the identification of the bright material as ice, which is great news for the mission. Ice is what Phoenix went all the way to Mars to study; it's what the team has been aiming for all these years.
Sands on Earth, Sands on Mars
One of the ways that planetary scientists try to understand the origin and evolution of landforms on other planets is by studying similar kinds of landforms or
Hayabusa update
JAXA has posted a note on their website on the status of Hayabusa, which apparently reached aphelion in late May. Hayabusa is Japan's amazing ion-powered mission to asteroid Itokawa, which touched down on Itokawa to grab a sample in mid-November 2005, but suffered an injury that has left in doubt its ability to return the sample capsule to Earth.
Phoenix Sol 2 press conference, in a nutshell
Emily hits the high points of today's press conference.
Some beautiful video from the Spirit and Opportunity landing sites
A majority of the people who work in planetary geology are usually associated with one or maybe two missions, doing all their research on the results from one instrument on one mission. But there are a few people whose expertise cuts across many space missions, and an even smaller number of people who seem to work on almost everything. Randy Kirk is one of those people.
White Rock through the Ages: Mars Reconnaissance Orbiter (2006-present)
I apologize for the long hiatus in this White Rock series, but I hope this entry will be worth the wait.
What's up in the solar system for the week of April 28
I thought it would be fun to start the week by taking stock of what's going on with all the active planetary missions out there.
A bit of fun with Mars Express images of Phobos
I recently found the focus to work on a big project: namely, downloading and examining every Mars Express High Resolution Stereo Camera image of Mars' two moons, Phobos and Deimos.

Frame a Pluto portrait
As New Horizons continues its journey (it's now approaching the orbital distance of Saturn, though it's very far from that planet in space), the mission is taking advantage of the recent experience with the Jupiter flyby to plan out the science operations for the Pluto-Charon encounter.
White Rock through the ages: Mars Express (2004-present)
When we last visited White Rock on Mars, both Mars Global Surveyor and 2001 Mars Odyssey were mapping the planet.
Saturn, Tethys, and Titan
I thought that today's image release from the Cassini imaging team was exceptionally pretty.
