New Horizons Day 2: Liquids on Pluto's surface?

Emily Lakdawalla • September 13, 2011

Jeff Moore's presentation was cool because of the discussion it stimulated. He considered what exogenic processes might be operating on Pluto's surface. What's an exogenic process? It's something that modifies the shape of the surface from the outside, and doesn't require the body to be geologically active inside.

New Horizons Day 2: Tectonic features on icy worlds

Emily Lakdawalla • September 09, 2011

The second day of the New Horizons Workshop on Icy Surface Processes was about geology and geophysics. This long post just covers the first talk of that day.

New Horizons workshop, day 1: Chemistry & climate on Pluto & other cold places

Emily Lakdawalla • August 30, 2011

Today and tomorrow I'm attending the New Horizons Workshop on Icy Surface Processes. The first day was all about the composition of the surface and atmosphere of Pluto, Charon, Triton, and other distant places.

The most exciting citizen science project ever (to me, anyway)

Emily Lakdawalla • June 21, 2011

A guest blogger here recently rounded up the large number of participatory research projects that are collectively known as citizen science. I think these are all very cool and I encourage you to check them out but none of them has yet inspired me to spend my precious time as grunt labor on a gigantic collective project. Until now.

The scale of our solar system

Emily Lakdawalla • May 02, 2011

Space.com has taken advantage of the infinitely scrollable nature of Web pages to produce a really cool infographic on the scales of orbital distances in the solar system.

365 Days of Astronomy Podcast: What's up in the second quarter of 2011

Emily Lakdawalla • April 07, 2011

Regular readers of this blog will find the content of today's 365 Days of Astronomy Podcast familiar, because it's an update on what the solar system exploration spacecraft are up to, based on my monthly "what's up" updates.

What's up in the solar system in April 2011

Emily Lakdawalla • March 31, 2011

April 2011 will see MESSENGER begin the science phase of its orbital mission at Mercury, and should, I think, also see the start of Dawn's approach observations of Vesta. At Mars, Opportunity is back on the road again, rolling inexorably toward Endeavour. At Saturn, Cassini will continue its focus on Saturn and Titan science.

LPSC 2011: Day 3: Moon, Mars, and Venus

Ted Stryk • March 10, 2011

Wednesday morning included some interesting conversations. Notably, I spoke with Pamela Gay, who is responsible for the MoonZoo citizen science program and who is presently working on developing a site through which the public will be able to help search for potential Kuiper belt objects for the New Horizons mission to encounter after the Pluto flyby.

What's up in the solar system in March 2011

Emily Lakdawalla • February 28, 2011

I don't think there's any question what the big event of this month will be: MESSENGER is finally, finally entering orbit at Mercury on March 18 at 00:45 UTC (March 17 at 16:45 for me).

Report from the 2011 New Horizons Science Team Meeting

Ted Stryk • January 24, 2011

The annual New Horizons Science Team Meeting was held last week at NASA's Ames Research Center.
