50 GB of data has been collected.....and yet to collect. Will arrive 2:1 compression. 1GB on the ground so far.
Heh...They had 65GB of flash memory available....didn't even get close to topping it off.

I think both of these should be "Gb", not "GB".  The recorders are 8GB (gigabytes) each (which is 64Gb), so there's no way to store 50GB plus the team has been talking mostly in "gigabits" in the past.

So, they probably have 1 gigabit (128MB) downloaded out of 50Gb (6.25GB).

Picky...picky... :o   ;D

Yeah...what's a factor of 8 among friends!

Another great line "Journalists love flyby's, they are science at the speed of journalism"
That, 51 minutes into the , was the lead-in for the following:
Quote from: Leo Enright with Irish Television
If you'll forgive me, I didn't want this week to fly by without remarking that this is the first planetary flyby in American history where the imaging specialist Jurrie van der Woude has not been intimately involved in distributing the imagery.  Jurrie was the sixth person at the front table at every flyby.  We completely relied upon him to provide us with imagery during those days.  I don't know if it was something about us journalists, but NASA chose an Air Force fighter pilot from the Dutch Air Force to deal with us.  But he was our link with the imaging teams for my entire professional career, and I didn't want this week to pass without mentioning Jurrie.  He was a great public servant, he was a terrific guy, and I suppose, as we in Ireland might say, he was a mensch
Quote from: Jeff Moore, New Horizons Co-investigator, NASA Ames
He was a really great guy.  Even when I was a young student, you could call him, he would pick up the phone, you could say, "Hi, I'm so-and-so from Pauls Valley, Oklahoma," and he would mail you pictures of the latest encounter.  It was fantastic.

Jurrie van der Woude (June 18, 1935 - March 20, 2015), JPL Media relation's specialist, retired March 2001.
* Biographical notes.
* Looking Back: Jurrie van der Woude's 37 years at JPL, Planetary Society interview from 2003. (2:17 - 29:20 of that 35 minute Planetary Radio show.  Includes a very humorous anecdote regarding his low expectation for Mars Pathfinder's success.)
* , a short video tribute including a clip of him speaking at the Planes of Fame Air Museum.  (Not space related.)
* Space Stories at The History of Space Photography at the Williamson Gallery, a collection of photos including several with Jurrie.

New Horizons Captures Two of Pluto's Smaller Moons

Pluto’s moon Nix (left), shown here in enhanced color as imaged by the New Horizons Ralph instrument, has a reddish spot that has attracted the interest of mission scientists.  The data were obtained on the morning of July 14, 2015, and received on the ground on July 18.  At the time the observations were taken New Horizons was about 102,000 miles (165,000 km) from Nix. The image shows features as small as approximately 2 miles (3 kilometers) across on Nix, which is estimated to be 26 miles (42 kilometers) long and 22 miles (36 kilometers) wide.

Pluto’s small, irregularly shaped moon Hydra (right) is revealed in this black and white image taken from New Horizons’ LORRI instrument on July 14, 2015, from a distance of about 143,000 miles (231,000 kilometers). Features as small as 0.7 miles (1.2 kilometers) are visible on Hydra, which measures 34 miles (55 kilometers) in length.

While Pluto’s largest moon Charon has grabbed most of the lunar spotlight so far, these two smaller and lesser-known satellites are now getting some attention.  Nix and Hydra – the second and third moons to be discovered – are approximately the same size, but their similarity ends there.

New Horizons’ first color image of Pluto’s moon Nix, in which colors have been enhanced, reveals an intriguing  region on the jelly bean-shaped satellite, which is estimated to be 26 miles (42 kilometers) long and 22 miles (36 kilometers) wide.

Although the overall surface color of Nix is neutral grey in the image, the newfound region has a distinct red tint.  Hints of a bull’s-eye pattern lead scientists to speculate that the reddish region is a crater. “Additional compositional data has already been taken of Nix, but is not yet downlinked. It will tell us why this region is redder than its surroundings,” said mission scientist Carly Howett, Southwest Research Institute, Boulder, Colorado. She added, “This observation is so tantalizing, I’m finding it hard to be patient for more Nix data to be downlinked.” 

Meanwhile, the sharpest image yet received from New Horizons of Pluto’s satellite Hydra shows that its irregular shape resembles the state of Michigan. The new image was made by the Long Range Reconnaissance Imager (LORRI) on July 14, 2015 from a distance of 143,000 miles (231,000 kilometers), and shows features as small as 0.7 miles (1.2 kilometers) across. There appear to be at least two large craters, one of which is mostly in shadow. The upper portion looks darker than the rest of Hydra, suggesting a possible difference in surface composition. From this image, mission scientists have estimated that Hydra is 34 miles (55 kilometers) long and 25 miles (40 kilometers) wide. Commented mission science collaborator Ted Stryk of Roane State Community College in Tennessee, “Before last week, Hydra was just a faint point of light, so it's a surreal experience to see it become an actual place, as we see its shape and spot recognizable features on its surface for the first time.”

Images of Pluto’s most recently discovered moons, Styx and Kerberos, are expected to be transmitted to Earth no later than mid-October.

Nix and Hydra were both discovered in 2005 using Hubble Space Telescope data by a research team led by New Horizons project scientist Hal Weaver, Johns Hopkins University Applied Physics Laboratory, Laurel, Maryland. New Horizons’ findings on the surface characteristics and other properties of Nix and Hydra will help scientists understand the origins and subsequent history of Pluto and its moons.

The irregular shape of those small moons increase the likelihood (IMO at least) that they are separately coalesced debris field products from the collision that created Charon.

Newest science update is coming at 2:00PM Eastern Daylight Time on NASA TV. (about 1.5 hrs from this post)

The new data to be presented is pre and post encounter data - stored and now received.

The other JG (Jim Green): This is the first time they're getting images and data taken with the spacecraft looking back (i.e. taken after closest approach)

Alan Stern showing a kickass bumper sticker designed by a systems engineer on the mission.
"My other vehicle explored Pluto" - which has the global view of Pluto which we've all seen over the past few days..

Until mid September - they're getting the data pertaining to the images already taken... (spectrometer, instrument headers etc.)

"For some of you if see a cardiologist, then you might want to leave the room"...
and shows a global image with 2x the previous best resolution.

I don't know if we should even screenshot this... I'm watching it on TV, and you'd need the large screen to do this thing justice :D

First set of data now down. Next set in September.
