Remembering the Pluto Campaign: A Success Story

Casey Dreier • July 22, 2013 • 3

The New Horizons mission to Pluto survived many near-death encounters with cancellation during its development. The Planetary Society worked the whole time to ensure it would launch.

New names for Pluto's little moons Kerberos and Styx; and a new moon for Neptune

Emily Lakdawalla • July 15, 2013 • 5

Pluto's moons, formerly known as "P4" and "P5," are now named Kerberos and Styx; I thought I'd help place them into context with a little help from Cassini. Also, Neptune now has a 14th known moon.

Great News: New Horizons to "stay the course" at Pluto

Emily Lakdawalla • June 17, 2013

This is extremely good news: after more than a year of analysis, the New Horizons mission and NASA have concluded and agreed that New Horizons' originally-planned trajectory past Pluto is likely safe from dust.

New Horizons: Encounter Planning Accelerates

Alan Stern • May 17, 2013 • 4

Back in 2005 and 2006, when Pluto’s second and third moons (Nix and Hydra) were discovered, searches by astronomers for still more moons didn’t reveal any. So the accidental discovery of Pluto’s fourth moon by the Hubble Space Telescope in mid-2011 raised the possibility that the hazards in the Pluto system might be greater than previously anticipated.

Pluto's seasons and what New Horizons may find when it passes by

Emily Lakdawalla • May 02, 2013 • 5

New Horizons might see a Pluto with a northern polar cap, a southern polar cap, or both caps, according to work by Leslie Young.

2011 HM102: A new companion for Neptune

Alex Parker • April 30, 2013 • 2

This month my latest paper made it to print in the Astronomical Journal. It's a short piece that describes a serendipitous discovery that my collaborators and I made while searching for a distant Kuiper Belt Object for the New Horizons spacecraft to visit after its 2015 Pluto flyby.

When will New Horizons have better views of Pluto than Hubble does?

Emily Lakdawalla • February 18, 2013 • 8

Last week, I posted an explainer on why Hubble's images of galaxies show so much more detail than its images of Pluto. Then I set you all a homework problem: when will New Horizons be able to see Pluto better than Hubble does? Here's the answer.

Why can Hubble get detailed views of distant galaxies but not of Pluto?

Emily Lakdawalla • February 14, 2013 • 22

How come Hubble's pictures of galaxies billions of light years away are so beautifully detailed, yet the pictures of Pluto, which is so much closer, are just little blobs? I get asked this question, or variations of it, a lot. Here's an explainer.

Kuiper Belt Objects Submitted to Minor Planet Center

Alex Parker • January 25, 2013 • 2

Recently, several of the Kuiper Belt Objects our team has discovered while searching for New Horizons post-Pluto flyby candidates have been submitted to the Minor Planet Center and their orbital information is now in the public domain.

Mat Kaplan • November 27, 2012

The New Horizons Pluto mission PI provides an update, and introduces his new public project called Uwingu.
