In Snow Crash, I wanted Neal Stephenson to have a franchulate called the “International Church of Pancakes” where those seeking refuge could go, catch breakfast and receive some uplifting moral message. But no – just a sword fighting Hiro and skate boarding Y.T. hanging out in the Metaverse. :thumb_up:

"New Horizons" in that dystopia would be passé. :(

I might consider joining your Church of Pancakes. But for the time being I'm waffling on that decision.

An ICOP franchise might lead to new horizons within the breakfast community but face far flung difficulties for their legal department. :yes:

I would still entertain investors for my high-flying concept for a down-to-earth restaurant; “Out of this World!” Diners would eat around a huge rotating globe of the Earth while viewing, behind, an awesome planetarium. I think my fav would be in the “Orion” section though the view from “Sagittarius” might be pretty good too. :thumb_up:

I have my architects and engineers working on it full-time. No, I'm afraid my plan wouldn't float which would just ruin the effect. :wink:

New Horizons Indicates Small Objects Are Rare in the Kuiper Belt

New Horizons Indicates Small Objects Are Rare in the Kuiper Belt
Southwest Research Institute | New Horizons | 2019 Feb 28
Using New Horizons data from the Pluto-Charon flyby in 2015, a Southwest Research Institute-led team of scientists have indirectly discovered a distinct and surprising lack of very small objects in the Kuiper Belt. The evidence for the paucity of small Kuiper Belt objects (KBOs) comes from New Horizons imaging that revealed a dearth of small craters on Pluto’s largest satellite, Charon, indicating that impactors from 300 feet to 1 mile (91 meters to 1.6 km) in diameter must also be rare.

The Kuiper Belt is a donut-shaped region of icy bodies beyond the orbit of Neptune. Because small Kuiper Belt objects were some of the “feedstock” from which planets formed, this research provides new insights into how the solar system originated. ...

“These smaller Kuiper Belt objects are much too small to really see with any telescopes at such a great distance,” said SwRI’s Dr. Kelsi Singer ... “New Horizons flying directly through the Kuiper Belt and collecting data there was key to learning about both large and small bodies of the Belt.” ...

Ultima Thule in 3D

Ultima Thule in 3D
NASA | JHU APL | SwRI | New Horizons | 2019 Mar 07

New Horizons Team Uses Stereo Imaging to Examine Kuiper Belt Object's Features

Cross your eyes and break out the 3D glasses! NASA’s New Horizons team has created new stereo views of the Kuiper Belt object nicknamed Ultima Thule – the target of the New Horizons spacecraft’s historic New Year’s 2019 flyby, four billion miles from Earth – and the images are as cool and captivating as they are scientifically valuable.

The 3D effects come from pairing or combining images taken at slightly different viewing angles, creating a “binocular” effect, just as the slight separation of our eyes allows us to see three-dimensionally. For the images on this page, the New Horizons team paired sets of processed images taken by the spacecraft’s Long-Range Reconnaissance Imager (LORRI) at 5:01 and 5:26 Universal Time on Jan. 1, from respective distances of 17,400 miles (28,000 kilometers) and 4,100 miles (6,600 kilometers), offering respective original scales of about 430 feet (130 meters) and 110 feet (33 meters) per pixel.

The viewing direction for the earlier sequence was slightly different than the later set, which consists of the highest-resolution images obtained with LORRI. The closer view offers about four times higher resolution per pixel but, because of shorter exposure time, lower image quality. The combination, however, creates a stereo view of the object (officially named 2014 MU69) better than the team could previously create.

3D Glasses, Flicker Animation, Parallel, and Cross-Eyed Views are available.

A Prehistoric Puzzle in the Kuiper Belt

NASA’s New Horizons Team Unravels the Many Mysteries of Ultima Thule

The farthest object ever explored is slowly revealing its secrets, as scientists piece together the puzzles of Ultima Thule – the Kuiper Belt object NASA's New Horizons spacecraft flew past on New Year's Day, four billion miles from Earth.

Analyzing the data New Horizons has been sending home since the flyby of Ultima Thule (officially named 2014 MU69), mission scientists are learning more about the development, geology and composition of this ancient relic of solar system formation. The team discussed those findings today at the 50th Lunar and Planetary Science Conference in The Woodlands, Texas.

Ultima Thule is the first unquestionably primordial contact binary ever explored. Approach pictures of Ultima Thule hinted at a strange, snowman-like shape for the binary, but further analysis of images, taken near closest approach – New Horizons came to within just 2,200 miles (3,500 kilometers) – have uncovered just how unusual the KBO's shape really is. At 22 miles (35 kilometers) long, Ultima Thule consists of a large, flat lobe (nicknamed "Ultima") connected to a smaller, rounder lobe (nicknamed "Thule"). ...

Because it is so well preserved, Ultima Thule is offering our clearest look back to the era of planetesimal accretion and the earliest stages of planetary formation. Apparently Ultima Thule's two lobes once orbited each other, like many so-called binary worlds in the Kuiper Belt, until something brought them together in a "gentle" merger. ...

Approach to Ultima Thule

Post by daddyo » Tue Apr 09, 2019 6:38 pm

There's a new movie of the approach/recede from Ultima Thule that has what look like a number of variable stars in the background (I counted 18 so far): http://pluto.jhuapl.edu/images/main-pag ... npage2.mp4

Another link with more information, noting there are synthesized frames in there as well so I imagine there are some artificial effects in the pulsing of the stars, for instance I see a group of 3-4 flashing in sequence near the beginning middle right row, and another up-right from center that flashes 4 times then pauses: http://pluto.jhuapl.edu/Galleries/Featu ... age_id=603

It is unlikely that there are any stars in this sequence that are variable enough to be visible. All of the apparently variable stars here are probably artifacts of the production process.

I’m just not sure how specific stars in this video, a very small percentage of those visible, cyclically pulse in intensity many times each. I don’t see anything unique about them in terms of apparent size/intensity etc. that might help produce this effect from interpolation or other video techniques. I would have to think that they do vary in intensity in some manner, at least.

IAU Approves Second Set of Pluto Feature Names
JHU APL | NASA | SwRI | New Horizons | 2019 Aug 08
PlutoFeaturesNomenclatureMap_color-01[1].jpg
This map, compiled from images and data gathered by New Horizons during its flight
through the Pluto system in 2015, contains Pluto feature names approved by the IAU.
Latest approved names are in yellow. (Credits: NASA/JHUAPL/SwRI/Ross Beyer)

Designations Were Proposed by NASA's New Horizons Mission Team

Several people and missions who paved the way for the historic exploration of Pluto and the Kuiper Belt – the farthest worlds ever explored – are honored in the second set of official Pluto feature names approved by the International Astronomical Union (IAU), the international authority for naming celestial bodies and their surface features.

The new names were proposed by NASA's New Horizons team, which carried out the first reconnaissance of Pluto and its moons with the New Horizons spacecraft in 2015. Along with a short list of official names the IAU had already approved, the mission science team had been using these and other place names informally to describe the many regions, mountain ranges, plains, valleys and craters discovered during the first close-up look at Pluto's surface. ...
  • Alcyonia Lacus, a possible frozen nitrogen lake on Pluto's surface, is named for the bottomless lake in or in the vicinity of Lerna, a region of Greece known for springs and swamps; the Alcyonian lake was one of the entrances to the underworld in Greek mythology.
  • Elcano Montes is a mountain range honoring Juan Sebastián Elcano (1476–1526), the Spanish explorer who in 1522 completed the first circumnavigation of the Earth (a voyage started in 1519 by Magellan).
  • Hunahpu Valles is a system of canyons named for one of the Hero Twins in Mayan mythology, who defeated the lords of the underworld in a ball game.
  • Khare crater honors planetary scientist Bishun Khare (1933–2013), an expert on the chemistry of planetary atmospheres who did laboratory work leading to several seminal papers on tholins – the organic molecules that probably account for the darkest and reddest regions on Pluto.
  • Kiladze crater honors Rolan Kiladze (1931–2010), the Georgian (Caucasus) astronomer who made pioneering early investigations the dynamics, astrometry and photometry of Pluto.
  • Lowell Regio is a large region honoring Percival Lowell (1855–1916), the American astronomer who founded Lowell Observatory and organized a systematic search for a planet beyond Neptune.
  • Mwindo Fossae is a network of long, narrow depressions named for the Nyanga (Eastern Dem. Rep. Congo/Zaire) epic hero who traveled to the underworld and after returning home became a wise and powerful king.
  • Piccard Mons is a mountain and suspected cryovolcano that honors Auguste Piccard (1884–1962), a 20th century inventor and physicist best known for his pioneering balloon flights into Earth's upper atmosphere.
  • Pigafetta Montes honors Antonio Pigafetta (c. 1491–c. 1531), the Italian scholar and explorer who chronicled the discoveries made during the first circumnavigation of the Earth, aboard Magellan's ships.
  • Piri Rupes is a long cliff honoring Ahmed Muhiddin Piri (c. 1470–1553), also known as Piri Reis, an Ottoman navigator and cartographer known for his world map. He also drew some of the earliest existing maps of North and Central America.
  • Simonelli crater honors astronomer Damon Simonelli (1959–2004), whose wide-ranging research included the formation history of Pluto.
  • Wright Mons honors the Wright brothers, Orville (1871–1948) and Wilbur (1867–1912), American aviation pioneers credited with building and flying the world's first successful airplane.
  • Vega Terra is a large land mass named for the Soviet Vega 1 and 2 missions, the first spacecraft to fly balloons on another planet (Venus) and to image the nucleus of a comet (1P/Halley).
  • Venera Terra is named for the Venera missions sent to Venus by the Soviet Union from 1961–1984; they included the first human-made device to enter the atmosphere of another planet, to make a soft landing on another planet and to return images from another planetary surface.

SwRI: SwRI: New Horizons Confirms Solar Wind Slows Farther from Sun

Post by bystander » Mon Dec 02, 2019 10:25 pm

SwRI-built instrument confirms solar wind slows farther away from the Sun
Southwest Research Institute | New Horizons | 2019 Dec 02
Measurements taken by the Solar Wind Around Pluto (SWAP) instrument aboard NASA’s New Horizons spacecraft are providing important new insights from some of the farthest reaches of space ever explored. In a paper recently published in The Astrophysical Journal, a team led by Southwest Research Institute shows how the solar wind — the supersonic stream of charged particles blown out by the Sun — evolves at increasing distances from the Sun.

“Previously, only the Pioneer 10 and 11 and Voyager 1 and 2 missions have explored the outer solar system and outer heliosphere, but now New Horizons is doing that with more modern scientific instruments,” said Dr. Heather Elliott, a staff scientist at SwRI, Deputy Principal Investigator of the SWAP instrument and lead author of the paper. “Our Sun’s influence on the space environment extends well beyond the outer planets, and SWAP is showing us new aspects of how that environment changes with distance.”

The solar wind fills a bubble-like region of space encompassing our solar system, called the heliosphere. From aboard New Horizons, SWAP collects detailed, daily measurements of the solar wind as well as other key components called “interstellar pickup ions” in the outer heliosphere. These interstellar pickup ions are created when neutral material from interstellar space enters the solar system and becomes ionized by light from the Sun or by charge exchange interactions with solar wind ions.

As the solar wind moves farther from the Sun, it encounters an increasing amount of material from interstellar space. When interstellar material is ionized, the solar wind picks up the material and, researchers theorized, slows and heats in response. SWAP has now detected and confirmed this predicted effect. ...
