A couple of weeks ago there were press releases coming out of the American Geophysical Union meeting about the discovery of a

CIRS gets another view of Enceladus' south polar hot spot

There's a new image product released from the Composite Infrared Spectrometer (CIRS) on Cassini, an instrument that is capable of measuring the temperatures on the extremely cold surfaces of Saturn's moons and rings.

Saturn from above (2006)

Ever since I first read about the plans for Cassini's tour of the Saturn system I've been looking forward to the current phase of the mission.

Breaking a tie on the Cassini science teams

This week's Cassini Project Update was particularly interesting, because it contained a story about how a difficult decision was made regarding the prioritizing of different science teams' desires for an upcoming Titan flyby.

Mars Odyssey is in safe mode

According to an update posted on the Athena website by Steve Squyres this morning, the Mars Odyssey orbiter has gone in to safe mode.

New Horizons spots Pluto!

Yesterday the New Horizons team released a flicker animation showing the spacecraft's first sight of Pluto, using the LORRI long-range imaging instrument.

New names for Enceladus' features

The IAU has just approved new names for 35 craters, dorsa, fossae, and sulci on the surface of Enceladus, based upon Cassini's high-resolution mapping of the little moon. What are dorsa, fossae, and sulci, you might ask?

Mars Exploration Rovers Update: New Milestones Set as Spirit Celebrates 1000 Sols, Opportunity Digs Victoria with a Little Help from a Friend

The Mars Exploration Rovers managed to log another couple of significant milestones this month even as they worked in place, on autopilot, for the last two weeks during superior conjunction, the period that occurs every 2 years when Earth and Mars orbit into positions on opposite sides of the Sun, obscured from each other. With the conjunction now over, the rovers are slated to be back in command operation by tomorrow, All Hallow's Eve or, more popularly, Halloween.

MESSENGER's Venus flyby successful

A press release just hit my mailbox stating that MESSENGER has been heard from since its Venus flyby, so there are now only four flybys to go before MESSENGER will be in orbit at Mercury!

Update: Monitoring the Weather?

The bigger the dream, the harder it is to achieve it. Our dream at The Planetary Society is to fly the first solar sail mission -- and prove the technology that might someday take humanity to the stars.

Mars Exploration Rovers Update: Spirit Perseveres, Opportunity Arrives at Victoria Crater

The Mars Exploration Rovers are reaching new milestones and gaining newfound energy as winter slowly begins to pass on the Red Planet. Once again, Opportunity commanded the spotlight as it pulled up to the rim of the massive Victoria crater this week and began returning images that may redefine the word spellbinding. Twin sister, Spirit, meanwhile, is resigned to stay in its northward-tilted position for another month looking at the same scenery in order to collect the maximum energy supply for its solar panels.

With Multi-Beam Receiver, SETI@home Takes Giant Step Forward

In seven intense days spent at the radio telescope Chief scientist Dan Werthimer and his colleagues completely overhauled the way SETI data is gathered at Arecibo, and ensured that SETI@home will henceforth enjoy the benefits of gathering data with the most advanced equipment anywhere in the world.
