JOHNS HOPKINS UNIVERISTY APPLIED PHYSICS LABORATORY, LAUREL, MD – Breathtaking new images taken by NASA’s New Horizons spacecraft during a New Year’s Day flyby yesterday unveil the tiny ‘Ultima Thule’ rock target as the most primitive solar system object ever seen up close in addition to being the farthest object ever visited by a spaceship from Earth – more than 4 billion miles away!
The new high resolution images released today by the New Horizons team and NASA reveal the object nicknamed ‘Ultima Thule’ to be a ‘contact binary’ connected by a very narrow neckline - and not two distinct bodies.
“Ultima Thule” is an unchanged fossil remnant formed during the dawn of our solar system some 4.5 Billion Years ago and counts as the first planetesimal ever seen, imaged and visited up close. It’s a cold virtually unaltered body formed during the birth of the solar system.
"Meet Ultima Thule!" said New Horizons Principal Investigator Alan Stern of the Southwest Research Institute in Boulder, Colorado, at todays (Jan. 2) post flyby media briefing as he showed the photo a cheering crowd erupting in applause at Johns Hopkins University Applied Physics Laboratory (JHU APL), in Laurel, MD.
"Just like with Pluto, we could not be happier. What you're seeing is the first contact binary ever explored by spacecraft. It's two completely separate objects that are now joined together."

The bi-lobal rock is shaped remarkably like a ‘snowman’ and consists of two connected balls roughly spherical in appearance.
The new world measures 19 miles (31 kilometers) in length. The team has unofficially nicknamed the larger sphere "Ultima" (12 miles/19 kilometers across) and the smaller sphere "Thule" (9 miles/14 kilometers across).

"This flyby is a historic achievement," said New Horizons Principal Investigator Alan Stern of the Southwest Research Institute in Boulder, Colorado, at todays (Jan. 2) post flyby media briefing.
"Never before has any spacecraft team tracked down such a small body at such high speed so far away in the abyss of space. New Horizons has set a new bar for state-of-the-art spacecraft navigation."

The baby grand shaped new horizons spacecraft flew within at a distance of merely 2,200 miles (3,500 kilometers).
Closest approach came just past midnight Tuesday shortly after the dawn of New Year’s Day 2019 at 12:33 a.m. EST as mission scientists, invited guests and the media including Space UpClose were on hand to witness the groundbreaking events first hand as they unfolded at the Johns Hopkins University Applied Physics Laboratory (JHU APL), in Laurel, MD.

“What a difference a day makes!” he remarked as he unveiled the 1st ever planetesimal seen up close by humanity compared to the pixelated fuzzy blob seen in every prior image through Dec. 30 – New Years Eve Eve.
It has remained pristine from the dawn of the formation of our solar system.
“Its the first contact binary ever explored and we could not be happier.”
The team also released the first color image which showed it to have a reddish cast- possibly from frozen organic materials mixed with water, methane and nitrogen ices.

The first
color image of Ultima Thule, taken at a distance of 85,000 miles (137,000
kilometers) at 4:08 Universal Time on January 1, 2019, highlights its reddish
surface. At left is an enhanced color image taken by the Multispectral Visible
Imaging Camera (MVIC), produced by combining the near infrared, red and blue
channels. The center image taken by the Long-Range Reconnaissance Imager
(LORRI) has a higher spatial resolution than MVIC by approximately a factor of
five. At right, the color has been overlaid onto the LORRI image to show the
color uniformity of the Ultima and Thule lobes. Note the reduced red coloring
at the neck of the object. The science team unveiled this image at the Jan 2, media

There were no distinct craters visible yet. But there are possible
crater-like features visible that may be confirmed or not when higher resolution images
reach earth next week.
Communications with the spacecraft will be interrupted a few days after it enters solar conjunction from around Jan 4 to 9. Transmission will restart when the ship reemerges from behind the sun.
"New Horizons is like a time machine, taking us back to the birth of the solar system. We are seeing a physical representation of the beginning of planetary formation, frozen in time," said Jeff Moore, New Horizons Geology and Geophysics team lead at today’s briefing.
"Studying Ultima Thule is helping us understand how planets form — both those in our own solar system and those orbiting other stars in our galaxy."
"We think what we're looking at is perhaps the most primitive object that has yet been seen by any spacecraft and may represent a class of objects which are the oldest and most primitive objects that can be seen anywhere in the present solar system."
"Its remarkable appearance, unlike anything we've seen before, illuminates the processes that built the planets four and a half billion years ago,” says the team.
Moore said that the two spheres likely joined as early as 99 percent of the way back to the formation of the solar system, colliding no faster than two cars in a fender-bender at perhaps just a few MPH.
"What we think we're looking at is the end product of a process which probably took place in only a few hundred thousand or maybe a few million years at the very beginning of the formation of the solar system," Moore explained.
“Its the first planetesimal we’ve ever explored up close.”
The albedo is very low varying between 6 to 13%. The remarkable neck is the brightest area, perhaps 5 miles in width.
Overall it’s as dark as potting soil.
New Horizons has been hurtling towards the unexplored outer limits of our Solar System since launching 13 years ago in Jan. 2006 and conducting the first up close flyby of Pluto – the ninth planet - in July 2015.
Pluto, the largest known body in the Kuiper Belt, was the first target explored by New Horizons during a fast flyby over three years ago during July 2015.
‘Ultima Thule’ is the second Kuiper Belt object that has now been explored up close by New Horizons.
The small icy rock in the Kuiper Belt is located some 1 Billion miles (1.6 Billion km) beyond Pluto and orbits 4.1 Billion miles (6.6 Billion km) from the Sun and the Earth .

New Horizons has been hurtling towards the unexplored outer limits of our Solar System since launching 13 years ago in Jan. 2006 and conducting the first up close flyby of Pluto – the ninth planet - in July 2015.
Pluto, the largest known body in the Kuiper Belt, was the first target explored by New Horizons during a fast flyby over three years ago during July 2015.
‘Ultima Thule’ is the second Kuiper Belt object that has now been explored up close by New Horizons.
The small icy rock in the Kuiper Belt is located some 1 Billion miles (1.6 Billion km) beyond Pluto and orbits 4.1 Billion miles (6.6 Billion km) from the Sun and the Earth .
The New Horizons team tapped ‘Ultima Thule’ as the nickname
for the spacecrafts second flyby target on New Year’s Day 2019 – “symbolizing this ultimate exploration by NASA” says Alan
Stern, the missions team leader and chief scientist.
The primitive frozen
world - officially known as 2014 MU69 – has now become
the farthest object ever explored up close by a manmade emissary in history when
NASA’s New Horizons spaceship zoomed past for a close encounter on Jan. 1, 2019 orbiting more than a billion miles beyond
Pluto, the most distant planet in our Solar System.
The
first ever up close examination of this distant object holds critical clues to
the formation of the outer solar system eons ago.
Stern
says New Horizons spacecraft is performing perfectly and all systems and
subsystems are just as good as the day they were launched in Jan. 2006 on a ULA
Atlas V rocket.
It
has enough power to operate through the mid-2030’s at least and can conduct a
third flyby.
The team says they will begin that search immediately using the LORRI camera and propose an extended mission to NASA in the summer of 2020.

composite of two images taken by New Horizons' high-resolution Long-Range
Reconnaissance Imager (LORRI), which provides the best indication of Ultima
Thule's size and shape so far. Preliminary measurements of this Kuiper Belt
object suggest it is approximately 20 miles long by 10 miles wide (32
kilometers by 16 kilometers). Team members at the Jan 2, 2018 JHU APL press briefing below. Credit:
