Good thing New Horizons didn't have bowling on the menu!

http://pluto.jhuapl.edu/News-Center/News-Article.php?page=20190101

We have a successful pass, reestablished communcations with the satellite, initial self-checks report all is well, and that New Horizons has a databank full of things to send us.  Happy new year!

3 images, taken around 70 minutes apart the day before, showing rotation. So the flattish light curve may just be an artifact of facing & slow rotation.

That is an excellent reminder that all the pictures we see of things out there aren't just static...  :thumbsup:

So it will be like week before the data fully assembled from the Probe?

Any word as to whether they've got a second target decided on?  I'd heard there was some consideration, and it's still got some fuel onboard for maneuver.
The next target hasn't been specified yet, but the New Horizons team has stated an interest in another flyby later in the 2020's.  I imagine there are a few candidates, its a matter of choosing one.

I wish it was possible get New Horizon's eyes on new dwarf planet they founded earlier this year, 2015 TG387, "The Goblin". Its a extreme trans-Neptunian object and sednoid in the outermost part of the solar system.

There's dozens of dwarf planets like it known out there in the Scattered Disk who'll neither get a visit.

The Goblin's orbit is unique, since it's way out there and scientists believe it could lead to new major planet that's way out in orbit around the sun.

It would have to be near New Horizons' course.  At the speed that the probe travels, it can't really turn so much as divert.  Objects have to be found on it's path so that the probe can maneuver into position.  Ultima Thule was discovered expressly for these reasons.  It wasn't known until people began searching for possible targets for New Horizons to fly by.  The next target will likey be similar in this regard.

I read that was confirmed, that we got lucky and the rotation axis was lined up clean on New Horizons.  Should make for a pleasant time mapping each side, then, if we're getting it on a polar shot instead of a one-side flyby.

So far, Ultima Thule appears to be a contact binary.   It shouldn't be long for more detailed images to be had, but I'm glad for what's available.

I'm waiting for "Armageddon 2", where they have to deal with soft aggregates - slightly harder than drilling into a hard chunk of ice ;)

Gravel is the new villain in this one. Hold on to your drill, it gets chunky from here...   

Here's a chart displaying reflectivity of Ultima Thule.  Images in this thread are courtesy of NASA and Johns Hopkins University and their Applied Physics Lab where the New Horizons team laboriously wait for data to trickle in.

Wouldn't a soft aggregate just shatter and burn up in the atmosphere?  ???

It does.  And scientists have already decided the larger lobe is called Ultima and the smaller lobe is Thule.  The size ratio is 3 to 1, and the pair most likely began contact near the very beginning of the solar system, after a "crash" at perhaps as slow as 3 to 4 kilometers per hour.

Note what appears to be a frostline at the point of contact.

It would rain, surely.  Lots of water ice locked in these bodies, plus the shear size.   But let's wait and see if there's a better answer from worltroll or kato.

Stern noted that the team has received less than 1 percent of all the data stored aboard New Horizons. It will take nearly two years to get it all.

Yeah, data transmission rates are about 1kb/s for New Horizons.  It's a twelve watt transmitter at four billion miles distance; even a laser's focus is going to spread that signal out so faintly it's nothing but a tiny whisper in the dark.

But we can hear you, honey, we hear you just fine.  Good job.

I wonder if they got any good spectroscopy data on that frost ring around the snowman's waist.  That's probably material that got pushed out from the subsurface as the two came into contact; it might give a glimpse what lies under the skin of Ultima Thule.

If so, then the mission is extremely lucky upon lucky.

It's as exciting as it is lucky.  Even if all contact binaries share the frost ring feature, it's awesome we were able to see it.

Looks like China has some wheels on the Moon.

Slashgear report showed snapshot of their moon rover rolling out.

Actually the wheels are one thing they changed with Yutu 2 in comparison to Yutu 1:



The suspension system is still the same as on NASA Mars rovers though.  ^-^

Looks like it's at double speed from the way the clock ticks down.  Still immensely cool.  And seeing the resolution pick up tinier and tinier micrometeoroid craters, it really shows you what earth would look like without an atmosphere.  Fifty tons a day indeed.
