The original "Puddles on Mars" story has been retracted
Today, New Scientist and researcher Ron Levin retracted the
...and MESSENGER's flyby was successful!
The Applied Physics Lab issued a press release this evening stating that the MESSENGER mission's second flyby of Venus was successful.
Flyby of Venus Speeds MESSENGER Onward to Mercury
The MESSENGER spacecraft is zeroing in on Venus for the most significant gravity assist maneuver of its long journey to Mercury.
Mimas, Dione, Rhea
There's been quite a lot of Mars on this page for the last week; it's time to remind ourselves that there are other places besides Mars in the solar system.
Mars Exploration Rovers Update: Spirit Finds "Explosive" Evidence of Past Water, Opportunity Revs Up, Revisits Cape of Good Hope
The Mars Exploration Rovers sent home field reports this past month -- some 1,200 days into their missions -- that drew gasps of amazement from both the science and engineering teams.
Windows Onto the Abyss: Cave Skylights on Mars
Today's set of image releases from the Mars Reconnaissance Orbiter HiRISE team included this one, of a fairly bland-looking lava plain to the northeast of Arsia Mons. Bland, that is, except for a black spot in the center.
New territory on Titan
The other day I posted a global view of Titan featuring new territory near the north pole. Now the imaging team has released a much higher resolution version of this view.
Many Cassini views of Tethys
Here we bring you fifteen different Cassini views of the same world, a cratered ball of ice called Tethys.
A billion dollars won't get you back to Enceladus or Titan
The Outer Planets Assessment Group or OPAG met two weeks ago, and the presentations from the meeting were recently posted online.
Twilit (probable) lakes near Titan's north pole
This is a cool picture that was released a couple of weeks ago by Cassini's camera team.
Tvashtar erupting -- the movie
I practically fell out of my chair when I saw this movie.
MESSENGER aims for Venus
The MESSENGER team announced today that they accomplished the penultimate trajectory correction maneuver necessary to line the spacecraft up for its second gravity-assist flyby of Venus.
Mars Exploration Rovers Update: Spirit Finds Past Water at Home, Opportunity Takes in Tierra del Fuego
The Mars Exploration Rovers (MERs) traveled to new targets and made discoveries ranging from the magnificent to the mundane in April, four fast weeks that essentially led both of the twin robot field geologists to the next phase of their explorations.
Cassini observes a new face of Iapetus
Cassini has just begun its 44th orbit of Saturn (called Rev 43), and is starting it off with lots of views of famously two-faced Iapetus.
Dione's south pole
Cassini got a nice
Space weather affects everyday life on Earth
According to a press release issued this morning by the National Oceanic and Atmospheric Administration, the enormous solar flare that erupted on December 5 and 6 last year was accompanied by an intense radio burst that caused large numbers of Global Positioning System recivers to stop tracking the signal from the orbiting GPS satellites.
Millions of soundings yield clues to Mars' weather
Two months after the start of Mars Reconnaissance Orbiter's primary science phase, the Mars Climate Sounder instrument has already acquired more than four million soundings, building toward a vast data set on the three-dimensional structure of Mars' atmosphere over the full Martian year of the orbiter's nominal mission.
