DPS 2010: Pluto and Charon opposition surges, Nix and Hydra masses, Pluto and Eris compositions

Emily Lakdawalla • October 25, 2010

An awful lot of the talks in the Pluto session on Tuesday morning, October 5, at the Division of Planetary Sciences meeting spent more time focusing on how bad weather conditions were during the astronomers' attempts to view Pluto as it occulted background stars than they did on any measurements or science that came out from the data.

Voyager Mission Status Bulletins: Jupiter and Saturn

Emily Lakdawalla • September 24, 2010

Last week I posted a stack of Voyager Mission Status Bulletins, which were once the main resource for space enthusiasts to follow the dramatic events and photos of an in-flight space mission.

How to Recognize Titan from Quite a Long Way Away

Emily Lakdawalla • August 09, 2010

You know, I could fill this blog almost entirely with the amazing images that Gordan Ugarkovic locates, processes into prettiness, and uploads to his Flickr account.

The Saturn system is always in motion, always changing. Saturn itself is a gas giant, with swirling storms, and like the other gas giants it has a host of moons flying around, perturbing each other's motions. And then there's the rings.

Sharpest-ever images of Daphnis

Emily Lakdawalla • July 06, 2010

As promised last week, Cassini has delivered its best photos yet of the tiny moon Daphnis, the ringmoon that is responsible for carving out the skinny Keeler gap at the outer edge of Saturn's A ring.

Two moons making waves in the rings

Emily Lakdawalla • June 18, 2010

Just a pretty picture post, a dramatic Cassini shot on the outer edge of the A ring captured earlier this month.

The most amazing image of Enceladus Cassini has captured yet

Emily Lakdawalla • May 19, 2010

Every time I think Cassini has captured the coolest image of Enceladus ever, it does better.

A Martian Moment in Time, revisited

Emily Lakdawalla • May 12, 2010

A good start to my day today: The New York Times' Lens Blog featured the "Martian Moment in Time" photo that Opportunity took last week in a really nice writeup. I'm so grateful, and still a little surprised, that the folks on the Mars Exploration Rover mission took this idea and ran with it!
