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

Posted by Emily Lakdawalla on 2010/10/25 11:18 CDT

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.

A Martian Moment in Time, revisited

Posted by Emily Lakdawalla on 2010/05/12 02:30 CDT

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!

Saturn's hexagon recreated in the laboratory

Posted by Emily Lakdawalla on 2010/05/04 12:32 CDT | 10 comments

A lot of readers have expressed interest in the origin of Saturn's north polar hexagon. The hexagon is a long-lived pattern in the clouds surrounding Saturn's north pole, which has been observed since the Voyagers passed by in 1980 and 1981.

Designing the Cassini Tour

Posted by John Smith on 2009/06/07 12:01 CDT

Each Titan flyby is not a fork in the road, but rather a Los Angeles style cloverleaf in terms of the dizzying number of possible destinations. So how did our current and future plans for the path of the Cassini spacecraft come to be? That's the question Dave Seal put to me since that's my job -- I am a tour designer.

Canto III: Hints of Equinox

Posted by David Seal on 2009/06/04 06:31 CDT

Saturn is rapidly approaching equinox, where the Sun passes through the ring plane (south-to-north, i.e. the northern vernal equinox), and its ring system (i.e. its great now-gloomy poorly-lit circles of large blocks of water ice) is starting to show some really interesting behavior.

A couple cool raw Cassini pics -- and a break in the data

Posted by Emily Lakdawalla on 2005/07/19 04:56 CDT

I monitor the Cassini website to keep my eye out for cool pictures, and it's usually relatively easy to figure out what the spacecraft is looking at (rings, moon, Saturn, whatever). Sometimes, though, the images can be very confusing.
