    Still amazing to think that only a couple of years ago, we only had blurry pixelated pictures of Pluto. So many quite modern books are now so old. And we're old too. We're like those oldies who remember a time when a picture of Planet Earth was just a map.

    What do you mean "like those oldies who remember a time when a picture of Planet Earth was just a map"? I do remember that time, and it lasted the first 10 years of my life.

    New Horizons Video Soars over Pluto’s Majestic Mountains and Icy Plains

    In July 2015, NASA’s New Horizons spacecraft sent home the first close-up pictures of Pluto and its moons – amazing imagery that inspired many to wonder what a flight over the distant worlds’ icy terrain might be like.

    Wonder no more. Using actual New Horizons data and digital elevation models of Pluto and its largest moon Charon, mission scientists have created flyover movies that offer spectacular new perspectives of the many unusual features that were discovered and which have reshaped our views of the Pluto system – from a vantage point even closer than the spacecraft itself.

    Enjoy the latest map of Pluto and Charon

    http://pluto.jhuapl.edu/News-Center/...?page=20170714

    "On July 14, 2015, NASA's New Horizons spacecraft made its historic flight through the Pluto system Ė providing the first close-up images of Pluto and its moons and collecting other data that has transformed our understanding of these mysterious worlds on the solar system's outer frontier.

    Scientists are still analyzing and uncovering data that New Horizons recorded and sent home after the encounter. On the two-year anniversary of the flyby, the team is unveiling a set of detailed, high-quality global maps of Pluto and its largest moon, Charon."

    You have seen the updated maps of Pluto and Charon. Now fasten your seat belts as NASA just released two videos to take you flying by both of them.

    https://www.space.com/37497-new-hori...niversary.html

    "You can relive New Horizons' epic Pluto flyby, thanks to two amazing videos NASA released Friday (July 14), the two-year anniversary of the landmark event.

    Both videos put the viewer aboard New Horizons on July 14, 2015, when the robotic probe zoomed within 7,800 miles (12,550 kilometers) of Pluto and captured history's first up-close images of the dwarf planet system."

    NASA's New Horizons Team Strikes Gold in Argentina

    A primitive solar system object that's more four billion miles (6.5 billion kilometers) away passed in front of a distant star as seen from Earth. Just before midnight Eastern Time Sunday (12:50 a.m. local time July 17), several telescopes deployed by the New Horizons team in a remote part of Argentina were in precisely the right place at the right time to catch its fleeting shadow — an event that's known as an occultation.

    In a matter of seconds, the team captured new data on its elusive target, an ancient Kuiper Belt object known as 2014 MU69. Weary but excited team members succeeded in detecting the spacecraft's next destination, in what's being called the most ambitious and challenging ground occultation observation campaign in history.

    "So far we have five confirmed occultations," said Marc Buie of the Southwest Research Institute (SwRI) in Boulder, Colorado, holding up five fingers as New Horizons scientists pored over the exhilarating initial data. Buie led a team of more than 60 observers who battled high winds and cold to set up a "picket fence" of 24 mobile telescopes in a remote region of Chubut and Santa Cruz, Argentina. Their goal: to spot the shadow of the mysterious Kuiper Belt object (KBO) that New Horizons will fly by on New Year's Day 2019 – to better understand its size, shape, orbit and the environment around it. Before these observations, only the Hubble Space Telescope successfully detected MU69, and even it had not been able to determine MU69's size or shape.

    Charon, Pluto's largest moon, features have been official named.

    https://www.iau.org/news/pressreleases/detail/iau1803/

    The International Astronomical Union (IAU), the internationally recognized authority for naming celestial bodies and their surface features, recently approved a dozen names proposed by NASA's New Horizons team, which led the first reconnaissance of Pluto and its moons in 2015 with the New Horizons spacecraft. The New Horizons team had been using many of the chosen names informally to describe the many valleys, crevices and craters discovered during the first close-up look at the surface Charon.

    Now a book "Chasing New Horizons: Inside the Epic First Mission to Pluto" has been released.

    http://www.spaceflightinsider.com/ed...nge-new-world/

    Close to three years after the historic New Horizons Pluto flyby wowed the world, mission principal investigator Alan Stern and astrobiologist and mission science team member David Grinspoon tell the riveting story of a monumental exploration 26 years in the making in their new book Chasing New Horizons: Inside the Epic First Mission to Pluto.

    Much like a novel, the book starts with a crisis, the loss of contact with the spacecraft just ten days before the flyby, then goes back to the beginning of everything and narrates the story chronologically, from Stern’s birth through the first thoughts of a Pluto mission just as Voyager 2 visited Neptune in 1989, and the many twists and turns, setbacks and victories that culminated in the triumphant 2015 Pluto flyby.

    More photos of Pluto have been released by NASA.

    http://www.spacedaily.com/reports/NA...izons_999.html

    After a few weeks of silence, the Pluto photo parade is back in action. On Friday, NASA released a new roll of images beamed back by the intrepid probe, New Horizons.

    The new images include additional close-ups of Pluto's rugged beauty -- the sphere's surface features revealed in new range and detail.

    "Pluto is showing us a diversity of landforms and complexity of processes that rival anything we've seen in the solar system," Alan Stern, a researcher at the Southwest Research Institute and lead scientists on the New Horizons project, said in a press release. "If an artist had painted this Pluto before our flyby, I probably would have called it over the top -- but that's what is actually there."

    Are you sure that's not a recycled story. I was under the impression that all Pluto images had already been released. Plus the date of the article, September 11, 2018?

    You could be right, I picked it up from space daily but did not notice the date of sep 2018!!!. A serch give a date of Aug 3, 2017 for the NASA web site. Sorry

    It's great you noticed. I've complained about SpaceDaily's sources for a while. The writing is mostly misinformed and often sensationalistic.

    "First Global Maps of Pluto and Charon from New Horizons Published"

    http://www.spacedaily.com/reports/Fi...ished_999.html

    Until 2015, it was not known whether icy Pluto or its largest moon, Charon, had mountains, valleys or even impact craters. After the spectacular success of New Horizons in July 2015, scientists were amazed at the towering peaks and deep valleys that were revealed in the returned data.

    Now, thanks to the efforts of the New Horizons team, the first official validated global map and topographic maps of these two bodies have been published and are available to all. The maps and the process of creating them are described in two new research articles published in the journal Icarus.

    To create the maps, New Horizons researchers, led by Universities Space Research Association (USRA) Senior Staff Scientist, Paul Schenk, at the Lunar and Planetary Institute, registered all the images from the Long Range Reconnaissance Imager (LORRI) and Multispectral Visible Imaging Camera (MVIC) systems together and assembled the mosaics.

    New Horizon team to try another stellar occultation of Kuiper Belt object known as 2014 MU69..

    http://www.spacedaily.com/reports/Ne...flyby_999.html

    Successfully observing an object from more than four billion miles away is difficult, yet NASA's New Horizons mission team is banking that they can do that-again.

    Preparations are on track for a final set of stellar occultation observations to gather as much information about the size, shape, environment, and other conditions around New Horizons' next flyby target, the ancient Kuiper Belt object 2014 MU69, nicknamed Ultima Thule.

    "New Horizons Team Successfully Observes New Stellar Occultation of Ultima Thule"

    http://www.americaspace.com/2018/08/...-ultima-thule/

    Astronomers have just completed another observation of New Horizons’ next flyby target, Ultima Thule (aka 2014 MU69), pass in front of a distant star (a stellar occultation), on Aug. 3-4, 2018. This is the third such occultation observed and the data gathered will help the mission team to prepare for the encounter, which is scheduled for Jan. 1, 2019.


    The data taken during the occultation will provide astronomers with more information about the size, shape and environment of Ultima Thule, which is a small Kuiper Belt Object (KBO) far beyond Pluto. Very little is known about it so far since it is so far away, but New Horizons will conduct a close flyby, even closer than when it flew past Pluto. At 4 billion miles (6.5 billion kilometers) from Earth, it will be the most distant object ever explored so far.

    For those here who are unfamiliar (like me ;-) with the target --- From Wiki : Ultima Thule, is a trans-Neptunian object located in the Kuiper belt. It is elongated in shape, possibly a contact binary or close binary system, with an estimated diameter of 30 km (20 mi).

    Here's an artist illustration of the encounter at space.com...pretty close fly-by.

    Looks strangely like the body the ESA arrived at and landed on.

    Well, the good news is that http://pluto.jhuapl.edu/soc/UltimaThule-Encounter/ is not a government website, so it should continue to be updated despite the shutdown.

    NASA TV was able to televise today's press briefings in realtime (e.g. NASA LIVE on Youtube), although now they're back to showing views of the Earth as seen from the ISS, alternating with replays of the news briefings. The ongoing live events which are taking place at APL are being shown at https://www.youtube.com/user/jhuapl

    I have to admit that I was somewhat disappointed by the press briefings in that I already was aware of most of what they discussed, other than a few of the specific details.

    They're press briefings. They're not for people like us; they're for normal people.

    Excuse my ignorance but how is the sentence you quoted from him considered "political"? The shutdown definitely has an impact on the space program and so allowed as per the forum rules last I checked (see bold).

    12. Politics & Religion

    Since this forum is devoted to science and discussions of politics and religion are both off-topic and tend to incite behavior we discourage, forum participants are generally prohibited from discussing religious and political issues. Please don't begin or contribute to a topic that's merely going to incite or fuel a flame war.

    However, the following exceptions apply:

    A) Political impact upon space programs, exploration, and science.

    I know what you meant. But for a moment I thought you were insinuating that the press are normal people.

    ETA: please understand this is from a press officer.

    I think it was just a friendly reminder to make sure to avoid going beyond what is allowed. I donít think it meant the poster had done something wrong.

    Anyway, Iím looking forward to some pretty pictures.

    Please folks, no commenting on moderator action in this thread! We know it's meant well, but it quickly derails threads. If you have a problem, question or other issue with any post, even a post from a mod or admin, please use the report button or a PM to express your concern, or if a public discussion is required, use the feedback forum.

    That said, the mod remark under discussion was indeed meant as just a reminder to not go into the political background or reasons for the U.S. government shutdown. However, the effects of the shutdown for space-related things are perfectly fine to discuss per exception A to rule 12, and simply asking for an alternate source of information would probably be allowed even without exception A. The moderator consensus, with zero dissent, is that there was nothing wrong with the post.

    (The offending post was removed voluntarily by the poster, which was not necessary, and we have already offered to restore it in a PM.)
