The team at @JHUAPL is preparing for the #NewYears flyby of #UltimaThule, the farthest object explored by a spacecraft ever - 4 billion miles from the Sun and ~1 billion miles from Pluto.https://twitter.com/i/status/1079439391142146048

Цитата[IMG]JHU Applied Physics LaboratoryОпубликовано: 30 дек. 2018 г.Summiting the Solar System is a story of exploration at its most ambitious and extreme. On January 1, 2019, NASA's New Horizons spacecraft flies by a small Kuiper Belt Object known scientifically as 2014 MU69, but nicknamed "Ultima Thule." Ultima is four billion miles from Earth, and will be the most ancient and most distant world ever explored close up. It is expected to offer discoveries about the origin and evolution of our solar system. Chosen by the team and the public, the nickname honors the mythical land beyond the edges of the known world. But "Summiting" is much more than the story of a sophisticated, plutonium-fueled robotic spacecraft exploring far from the Sun. The New Horizons mission is powered as much by the passions of a small team of humans--men and women, scientists and engineers--for whom pushing the frontiers of the known, climbing the very peaks of the possible, has been the dream of many decades.

ЦитатаJHU Applied Physics LaboratoryОпубликовано: 30 дек. 2018 г.On January 1, 2019, Ultima Thule, and object in the Kuiper Belt four billion miles from Earth, will be the most ancient and most distant world ever explored close up. Ultima is expected to offer discoveries about the origin and evolution of our solar system. "Summiting" goes behind the scenes of the most ambitious occultation campaigns ever mounted, as scientists deployed telescopes to Senegal and Colombia in 2018, and Argentina, South Africa and New Zealand in 2017, to glimpse Ultima as it passed in front of a star, and gathered data on the object's size and orbit that has been essential to planning the flyby. Mission scientists recall the astonishing scientific success of flying through the Pluto system in 2015, and use comparative planetology to show how Earth and Pluto are both amazingly different and--with glaciers, tall mountains, volcanoes and blue skies--awesomely similar. Appealing to space junkies and adrenaline junkies alike, "Summiting" brings viewers along for the ride of a lifetime as New Horizons pushes past Pluto and braves an even more hazardous unknown.

"About 4-5 hours after flyby it will turn back to Earth and we will start to get the high res images back [of #UltimaThule]." @plutoport

Цитата12/31/2018 00:48 Stephen ClarkHal Weaver, the New Horizons project scientist at APL, says Ultima Thule appears to be a quickly-rotating object, based on imagery that beginning to offer the first information about the spacecraft's flyby target."Our team has been making little clay figures (guessing) here's what we think it looks like today based on the current information we have," Weaver says."How fast is it rotating? A few hours, tens of hours, or days?"There's some indication, some hint, that maybe this is a fast rotator," Weaver says. "The little bit that we've been able to tease out suggests that it may be rotating pretty quickly, but we've been up and down on the team as to whether or not we believe that."If Ultima Thule is spinning relatively quickly, that would be good news for the researchers eagerly awaiting their first look at such a primitive world.Weaver says the New Year's encounter with Ultima Thule is a once-in-a-lifetime event for many people on the New Horizons team -- due to the time it takes to prepare a space mission and have it travel from Earth to the Kuiper Belt."There's nothing else on the books to do anything like this," Weaver says."I don't think I'll be alive when the next cold classical Kuiper Belt Object is encountered, so we're all looking forward to this flyby. In that respect, this is the frontier of planetary science ... As a civilization, we're stepping out into this third zone of the solar system that was not even discovered until the early 1990s."

The @NASANewHorizons team reports the #spacecraft is healthy and on track to flyby #UltimaThule a little after midnight! Send your questions to the team at #askNewHorizons & watch the AMA LIVE at 3pm (ET)! http://bit.ly/jhuapl-flyby-watch ...
