New Horizons extended mission target selected

Emily Lakdawalla and Casey Dreier • September 01, 2015 • 6

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.

Looking back at Pluto

Emily Lakdawalla • July 24, 2015 • 17

I don't think anyone was prepared for the beauty -- or the instant scientific discoveries -- in this "lookback" image of Pluto, captured by New Horizons shortly after it flew by.

What in the world(s) are tholins?

Sarah Hörst • July 22, 2015 • 10

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”.

New Horizons: Awaiting the data

Emily Lakdawalla • July 19, 2015 • 32

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.

Latest New Horizons picture of Charon: oddly familiar

Emily Lakdawalla • July 16, 2015 • 14

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.

First look at New Horizons' Pluto and Charon images: "baffling in a very interesting and wonderful way"

Emily Lakdawalla • July 15, 2015 • 33

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.

New Horizons "phones home" after Pluto flyby

Emily Lakdawalla • July 14, 2015 • 7

After a wait of more than 22 hours with no communication, New Horizons "phoned home" precisely on schedule after its flyby of Pluto. The signal was received at 00:52:37 UT | 20:52:37 ET | 17:52:37 PT. As planned, New Horizons returned no images with the Phone Home downlink. But every bit of telemetry indicated that the flyby executed successfully.
