A fifth moon for Pluto, and a possible hazard for New Horizons

Posted by Emily Lakdawalla on 2012/07/16 02:55 CDT | 9 comments

Pluto is now known to have at least five moons (Charon, Nix, Hydra, P4, and the newly discovered P5), and its burgeoning population might pose a risk to New Horizons during its flyby, three years from now.

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

Posted by Emily Lakdawalla on 2011/09/13 01:27 CDT

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.

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

Posted by Emily Lakdawalla on 2011/06/21 08:23 CDT

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.

What's up in the solar system in April 2011

Posted by Emily Lakdawalla on 2011/03/31 03:59 CDT

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

Posted by Ted Stryk on 2011/03/10 11:11 CST

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

Posted by Emily Lakdawalla on 2011/02/28 02:43 CST

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).

What's up in the solar system in January 2010

Posted by Emily Lakdawalla on 2010/01/04 01:29 CST

While we don't have Moon bases, we do have plenty of spacecraft. Before I get into my more detailed look at the activities of the 20-odd spacecraft wandering about the solar system, I thought I'd look ahead to 2010 more generally and see what the year has in store for us.

Frame a Pluto portrait

Posted by Emily Lakdawalla on 2008/04/07 01:27 CDT

As New Horizons continues its journey (it's now approaching the orbital distance of Saturn, though it's very far from that planet in space), the mission is taking advantage of the recent experience with the Jupiter flyby to plan out the science operations for the Pluto-Charon encounter.
