What to expect when you're expecting a flyby: Planning your July around New Horizons' Pluto Pictures (version 2)

Emily Lakdawalla • June 24, 2015

Three months ago, I posted an article explaining what to expect during the flyby. This is a revised version of the same post, with some errors corrected, the expected sizes of Nix and Hydra updated, and times of press briefings added.

New Horizons update: Resolving features on Charon and seeing in color

Emily Lakdawalla • June 23, 2015

Only about three weeks remain until the flyby — it's getting really close! I almost don't want the anticipation to end. New Horizons is now getting color images and is seeing features on Charon. Deep searches have yielded no new moons.

Pluto and Charon spin among the stars

Emily Lakdawalla • June 16, 2015

I've spent a happy couple of days playing with raw data downloaded from the New Horizons website, making animations of the dances of Pluto and Charon.

An enigmatic line across Pluto: Plutonian canali!?

Emily Lakdawalla • June 09, 2015

Pluto and Charon are growing larger in New Horizons' forward view, beginning to develop distinct personalities. A version of recent New Horizons photos processed by Björn Jónsson reveals an enigmatic dark line. Our maps of Pluto's surface are now as good as our maps of Mars and Venus, circa 1900!

A (very) few more details on Pluto

Emily Lakdawalla • June 01, 2015

Last week the New Horizons mission released a few new processed versions of their latest and greatest images of Pluto. They're the best images of Pluto that Earth has ever seen, but they're still a long way from what New Horizons will be able to show us, six weeks from now.

Two Months from Pluto!

Paul Schenk • May 19, 2015

Two months. Eight and half weeks. 58 days. It's a concept almost too difficult to grasp: we are on Pluto's doorstep.

New Horizons spots Kerberos and Styx

New Horizons has now spotted every one of Pluto's satellites...all the ones we know about, that is.

New Horizons sees surface features on Pluto, begins raw image release

Emily Lakdawalla • April 29, 2015

Today the New Horizons team released a new animation of images taken on approach to Pluto. The animation clearly shows how Pluto wobbles around the Pluto-Charon barycenter. It also shows something more exciting to the scientists: variations in brightness across the surface of Pluto. They also began releasing raw images to the Internet.

The One Earth Message Project is going to send a message to the stars, and we invite members of the Planetary Society to join us in this historic endeavor.

What Color Does the Internet Think Pluto Is?

Alex Parker • April 20, 2015

Astronomers have known for a long time that Pluto’s surface is reddish, so where did the common idea that Pluto is blue come from?

New views of three worlds: Ceres, Pluto, and Charon

Emily Lakdawalla • April 16, 2015

New Horizons took its first color photo of Pluto and Charon, while Dawn obtained a 20-frame animation looking down on the north pole of a crescent Ceres.

Ceres Gets Real; Pluto Lurks

Paul Schenk • March 27, 2015

Although we are still along way from understanding this fascinating little body, Ceres is finally becoming a real planet with recognizable features! And that's kinda cool.

The Mapping of Pluto Begins Today

Mark Showalter • March 20, 2015

When New Horizons flies past Pluto in July, we will see a new, alien landscape in stark detail. At that point, we will have a lot to talk about. The only way we can talk about it is if those features, whatever they turn out to be, have names.

New Horizons returns first images from mission's Pluto approach phase

Emily Lakdawalla • February 04, 2015

Here they are, the first images of Pluto from the approach phase of the New Horizons mission. Science has begun; we're on the home stretch!

Talking to Pluto is hard! Why it takes so long to get data back from New Horizons

Emily Lakdawalla • January 30, 2015

As I write this post, New Horizons is nearing the end of a weeklong optical navigation campaign. The last optical navigation images in the weeklong series will be taken tomorrow, but it will likely take two weeks or more for all the data to get to Earth. Two weeks! Why does it take so long?

Year of the 'Dwarves': Ceres and Pluto Get Their Due

Paul Schenk • January 15, 2015

This year we achieve the first exploration of these curious but fascinating objects. Paul Schenk explains what we may learn about them.

Planetary exploration in 2015: The Year of the Dwarf Planet

Emily Lakdawalla • December 31, 2014

Looking ahead to what we can expect from Earth's exploration of the rest of the solar system in 2015, there's an obvious theme: Dwarf planets.
