New Horizons "back in action" after safe mode event, ready to resume encounter science

Emily Lakdawalla • July 06, 2015 • 10

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.

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

Emily Lakdawalla • June 23, 2015 • 13

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

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.

A (very) few more details on Pluto

Emily Lakdawalla • June 01, 2015 • 9

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.

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

Emily Lakdawalla • April 29, 2015 • 11

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 Mapping of Pluto Begins Today

Mark Showalter • March 20, 2015 • 7

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 spots Nix and Hydra circling Pluto and Charon

A series of images just sent to Earth from New Horizons clearly shows Pluto's moons Nix and Hydra orbiting the Pluto-Charon binary.

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

Emily Lakdawalla • February 04, 2015 • 10

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!

Twinkling worlds in motion: New Horizons' first optical navigation images of Pluto and Charon

Emily Lakdawalla • August 07, 2014 • 15

What's that in the distance? A binary star? Those are two little round worlds dancing in circles, whirling around a point in space located between the two of them. It's Pluto and Charon, clearly separated by New Horizons' camera.

Will we find signs of tectonics on Pluto? And what would that mean?

Joseph O'Rourke • May 26, 2014 • 1

Joseph O’Rourke summarizes a recently submitted paper on tectonic activity on Pluto after the Charon-forming impact.
