Today, New Horizons released a stunning new image of Pluto's backlit mountains and hazes. I explain how the image was taken with its Ralph Multispectral Visible Imaging Camera.

Last Friday the Internet received its first post-encounter pile of goodies from the New Horizons flyby of the Pluto system.

New Horizons has begun the long process of downlinking all the images it acquired during its July Pluto flyby.

The New Horizons mission has formally selected its next target after Pluto: a tiny, dim, frozen world currently named 2014 MU69. The spacecraft will perform a series of four rocket firings in October and November to angle its trajectory to pass close by 2014 MU69 in early January 2019. In so doing, New Horizons will become the first flyby craft to pass by a target that was not discovered before the spacecraft launched.

It has been a difficult wait for new New Horizons images, but the wait is almost over; Alan Stern announced at today's Outer Planets Advisory Group meeting that image downlink will resume September 5. In the meantime, a few space fans are making the most of the small amount of data that has been returned to date.

The question “why is Pluto red” has been answered with a word that most people have never heard of and perhaps even fewer people can actually define—“tholins”.

So many new image goodies from the Pluto system!

New Horizons' encounter and data downlinks have been going exactly as planned, but the raw image website has not been updated for many days. What's going on? I found out.

The New Horizons team released one more picture from Tuesday's encounter, one of three high-resolution images from a mosaic that crossed the center of Charon's disk, and it took me a while to figure out what it reminded me of.

Today's press briefing at the Applied Physics Laboratory in California was preceded by hours of New Horizons team members cryptically dropping hints on Twitter at astonishing details in the seven images downlinked since the flyby. The images are, in fact, astonishing, as well as beautiful, surprising, and puzzling.

Feast your eyes upon it!

Now that I have a reasonable-resolution global color view of Pluto, I can drop it into one of my trademark scale image montages, to show you how it fits in with the rest of the similar-sized worlds in the solar system: the major moons and the biggest asteroids.

At a press briefing this morning, New Horizons principal investigator Alan Stern divulged some extremely preliminary first science results from the New Horizons Pluto encounter. Science results include Pluto's diameter and information on its surface composition and atmospheric escape.

In the span of a few days, Pluto and Charon have turned from spots into worlds. The latest images from New Horizons are showing Pluto and Charon to have unique faces, distinct from any other icy worlds in the solar system.

New Horizons—what will be NASA’s greatest success of 2015—was cancelled multiple times in its early life, and many times before that in its previous incarnations. A mission to Pluto was not inevitable, despite the overwhelming scientific and public excitement.

NASA held a press briefing today to explain the nature and cause of the spacecraft anomaly that halted science on New Horizons for four days as it was on its terminal approach to Pluto. As of the moment that I write this post, New Horizons is not yet performing science observations, but it will resume them tomorrow, July 7.
