Io and Europa glimpsed by a retreating New Horizons

Emily Lakdawalla • April 02, 2007

This image is beautiful for many reasons. It was captured by the MVIC imaging spectrometer, part of the Ralph instrument, on New Horizons, as it left the Jupiter system on March 2, 2007.

Io erupts, in color

The last one of New Horizons imaging instruments has finally checked in with a lovely image from the Jupiter flyby

Another amazing Io image from New Horizons

Emily Lakdawalla • March 13, 2007

The Tvashtar eruption continues to amaze. All this time between Galileo and New Horizons, Io's volcanoes have probably continually produced spectacular eruptions like these.

New Horizons sees Io erupting!

Emily Lakdawalla • February 27, 2007

There were two new pictures posted on the New Horizons Science Operations Center website this morning, of Io, and if you enhance the images a bit, there are two clear volcanic plumes visible on the limb -- Tvashtar and Prometheus are active!

New Horizons update and a website roundup

New Horizons Jupiter Encounter Timeline

Emily Lakdawalla • January 31, 2007

A year after its launch on January 19, 2006, New Horizons is fast closing in on Jupiter, the first target on its near decade-long journey. On February 28 the spacecraft will approach to within 2.3 million kilometers (1.4 million miles) of Jupiter before speeding along on to its way to the edge of the solar system.

New Horizons' raw images are now online

Emily Lakdawalla • January 23, 2007

I got an email from John Spencer this morning telling me that the mission had posted all of New Horizons' most recently acquired images on the mission website.

New Horizons is targeting Jupiter!

Emily Lakdawalla • January 10, 2007

New Horizons' Jupiter encounter is officially underway!

New Horizons spots Pluto!

Yesterday the New Horizons team released a flicker animation showing the spacecraft's first sight of Pluto, using the LORRI long-range imaging instrument.

New Horizons is locked on target for its Jupiter encounter

Emily Lakdawalla • November 02, 2006

Alan Stern just posted a detailed update on the status of New Horizons in his PI's Perspective blog on the mission website.

New Horizons tracks an asteroid

Emily Lakdawalla • June 15, 2006

New Horizons is spending the summer traversing the asteroid belt. I haven't written a lot about New Horizons lately because the mission has been going so uneventfully well. But now I've got something to write about: data!!

New Horizons passes farther from the Sun than Mars today!

Emily Lakdawalla • April 06, 2006

Today is the day that New Horizons passes Mars' orbit (not that Mars is anywhere close to New Horizons right now).

Where is New Horizons now?

Emily Lakdawalla • January 30, 2006

It's in space, of course, and has a very, very long way to go to Pluto (nearly 50 billion kilometers). But it's finally more than 1 Astronomical Unit from the Sun.

New Horizons update

Emily Lakdawalla • January 23, 2006

I received a lot of email over the weekend about New Horizons. Many of them were expressing concern about how little news there has been since launch. Have no fear.

After the launch

John Spencer • January 19, 2006

We just got back from the real post-launch party, following two non-post-launch parties on the last two evenings. This was more like it.

New Horizons post-launch press conference

Emily Lakdawalla • January 19, 2006

I am updating this as I take notes from the press conference.

OK, back to New Horizons!

Emily Lakdawalla • January 19, 2006

So the Stardust press conference is still going on on NASA TV, but I am now turning to the Internet to monitor the status of New Horizons' third attempted launch day.

How New Horizons' launch date affects its arrival date

Emily Lakdawalla • January 18, 2006

I was looking at that table of launch times for New Horizons and realized that the table included another valuable column of data that I hadn't noticed before: it tells you what year New Horizons will arrive, for each of the possible launch dates.

Philosophical after the first day's launch attempt

John Spencer • January 17, 2006

Oh well, the Sun sets on an earthbound New Horizons at least one more time. The first day's launch attempt was a strange experience in retrospect.
