Mars Exploration Rovers update: Spirit and Opportunity are both still talking to Earth

Emily Lakdawalla • July 23, 2007

Both Spirit and Opportunity are still suffering under incredibly dark skies, but, amazingly, they are both "power-positive," meaning that they are managing to produce enough power from the limited amount of sunlight to keep the batteries fully charged.

The original "Puddles on Mars" story has been retracted

Emily Lakdawalla • June 12, 2007

Today, New Scientist and researcher Ron Levin retracted the "puddles on Mars" claim in the face of evidence that the "puddles" were on sloping surfaces. I've updated my original blog entry in response to the claim to that effect.

...and MESSENGER's flyby was successful!

Emily Lakdawalla • June 05, 2007

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

Emily Lakdawalla • June 05, 2007

The MESSENGER spacecraft is zeroing in on Venus for the most significant gravity assist maneuver of its long journey to Mercury.

Mimas, Dione, Rhea

Emily Lakdawalla • May 31, 2007

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.

Windows Onto the Abyss: Cave Skylights on Mars

Emily Lakdawalla • May 23, 2007

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

Emily Lakdawalla • May 22, 2007

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

Emily Lakdawalla • May 21, 2007

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

Emily Lakdawalla • May 17, 2007

The Outer Planets Assessment Group or OPAG met two weeks ago, and the presentations from the meeting were recently posted online.

Emily Lakdawalla • May 16, 2007

This is a cool picture that was released a couple of weeks ago by Cassini's camera team.

MESSENGER aims for Venus

Emily Lakdawalla • May 02, 2007

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.

Cassini observes a new face of Iapetus

Emily Lakdawalla • April 20, 2007

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

Emily Lakdawalla • April 09, 2007

Cassini got a nice "Voyager-class" view of Saturn's moon Dione yesterday, passing about 250,000 kilometers from the moon's south pole.

Space weather affects everyday life on Earth

Emily Lakdawalla • April 04, 2007

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.

Enceladus is a drag on Saturn's radio emissions

Emily Lakdawalla • March 22, 2007

What should arrive in my inbox today but a press release from the Cassini RPWS and magnetometer teams saying, in part, "the little moon Enceladus is weighing down giant Saturn's magnetic field so much that the field is rotating slower than the planet."

LPSC: Tuesday: Volcanism and tectonism on Saturn's satellites

Anne Verbiscer • March 14, 2007

I received this report on the Tuesday afternoon special session on volcanism and tectonism on Saturn's satellites from Anne Verbiscer, an astronomer from the University of Virginia who I first met at the Division of Planetary Sciences meeting in 2005.

LPSC: Wow, Titan can be a Really Flat Place, and other Titan Talks

Jason Perry • March 12, 2007

Jason Perry, a member of the Cassini Imaging Team and an undergraduate student at the University of Arizona, reports from the Titan sessions.

Cassini's global views of Saturn and its rings

Emily Lakdawalla • March 08, 2007

Since late January Cassini has been acquiring several sets of images that show all of Saturn's globe and ring system at once from perspectives well above and below the ring plane.

Saturn from above

Emily Lakdawalla • March 01, 2007

OK, I had planned to confine my posts this week to Rosetta and New Horizons, but I could not let these images sit on my computer until next week.

New Horizons' Jupiter flyby was successful!

Emily Lakdawalla • February 28, 2007

According to a press release issued minutes ago, New Horizons has successfully completed its close flyby of Jupiter.

New Horizons sees Io erupting!

Emily Lakdawalla • February 27, 2007

There were two new pictures posted on the New Horizons Science Operations Center website this morning, of Io, and if you enhance the images a bit, there are two clear volcanic plumes visible on the limb -- Tvashtar and Prometheus are active!

Rosetta Was Here

Emily Lakdawalla • February 25, 2007

This amazing view was captured by the CIVA camera on Rosetta's Philae lander just four minutes before its closest approach to Mars on February 25, 2007. The spacecraft was only 1,000 kilometers above the planet.

A new way to darken Iapetus

Emily Lakdawalla • February 21, 2007

Iapetus is one of the many fascinating bodies in the Saturn system.

Autumn comes to Mars' north pole

Emily Lakdawalla • February 18, 2007

It's easy to forget that Mars is another such world with cloudy weather and seasonally varying climate. This lovely image release from the CRISM instrument on Mars Reconnaissance Orbiter brings that point home.

New Horizons update and a website roundup

Emily Lakdawalla • February 03, 2007

I've just posted a very detailed timeline of New Horizons' encounter with Jupiter -- take a look!

Saturn from above, in color

Emily Lakdawalla • January 31, 2007

I wrote recently about a set of images of Saturn acquired by Cassini from a unique vantage point, well above the planet, looking down on the rings. Someone has taken up the challenge of assembling the 36 different images into a single mosaic, in color, and it is as lovely as I'd hoped.

New Horizons Jupiter Encounter Timeline

Emily Lakdawalla • January 31, 2007

A year after its launch on January 19, 2006, New Horizons is fast closing in on Jupiter, the first target on its near decade-long journey. On February 28 the spacecraft will approach to within 2.3 million kilometers (1.4 million miles) of Jupiter before speeding along on to its way to the edge of the solar system.

A cool Cassini ring plane crossing animation

Emily Lakdawalla • January 26, 2007

Another recent, cool set of images that came down from Cassini was a series taken last week as the spacecraft crossed the ring plane.

New Horizons' raw images are now online

Emily Lakdawalla • January 23, 2007

I got an email from John Spencer this morning telling me that the mission had posted all of New Horizons' most recently acquired images on the mission website.

The Saturn view I've been waiting for

Emily Lakdawalla • January 22, 2007

Over the weekend, Cassini acquired a set of images that will (I am assuming) eventually be used to produce a glorious portrait of the ringed planet from a point of view that's never been seen before.

More Cassini RADAR images

Emily Lakdawalla • January 15, 2007

Cassini just flew by Titan again on Saturday, and should have acquired a new swath of RADAR data.

New Horizons is targeting Jupiter!

Emily Lakdawalla • January 10, 2007

New Horizons' Jupiter encounter is officially underway!

Titan's Lakes

Emily Lakdawalla • January 03, 2007

The first peer-reviewed article on Titan's lakes comes out in tomorrow's issue of the journal Nature.
