NASA mission plans New Year's flyby of object four billion miles away - CNN
The flyby is anticipated to occur at 12:33 a.m. ET on January 1. It would be the first exploration of a small Kuiper Belt object up shut — and essentially the most primitive world ever noticed by a spacecraft. Ultima Thule orbits a billion miles past Pluto and might be a little bit of a time capsule from the early photo voltaic system.
New Horizons is shifting by house at 31,500 miles per hour, and it has one probability to get it proper because it zips previous the thing.
The Kuiper Belt is the sting of our photo voltaic system, a part of the unique disk from which the solar and planets fashioned. The craft is now so removed from Earth that it takes six hours and eight minutes to obtain a command despatched from Earth.
If New Horizons sounds acquainted, it is as a result of that is the spacecraft that carried out a historic flyby of Pluto in 2015, sending again unprecedented photos of the dwarf planet and revealing new particulars about Pluto and its moons. The New Horizons mission was prolonged in 2016 to go to this Kuiper Belt object. The mission was launched in 2006 and took a 9½-year journey by house earlier than reaching Pluto.
New Horizons will fly 3 times nearer to Ultima than it did by Pluto, coming inside 2,200 miles of it and offering a greater take a look at the floor. After the short flyby, New Horizons will proceed on by the Kuiper Belt with different deliberate observations of extra objects, however the mission scientists mentioned that is the spotlight.

The object was beforehand referred to as 2014 MU69. The title Ultima Thule was chosen by a nickname marketing campaign hosted by the New Horizons staff.
Thule was a legendary island on medieval maps, considered essentially the most northern level on Earth. Ultima Thule basically means “beyond Thule,” which suggests one thing that lies past what is thought. It’s becoming, contemplating New Horizons’ pioneering journey.
“MU69 is humanity’s next Ultima Thule,” Alan Stern, New Horizons principal investigator from the Southwest Research Institute, mentioned in an announcement. “Our spacecraft is heading beyond the limits of the known worlds, to what will be this mission’s next achievement. Since this will be the farthest exploration of any object in space in history, I like to call our flyby target Ultima, for short, symbolizing this ultimate exploration by NASA and our team.”
Once the flyby occurs and mission scientists perceive extra about simply what Ultima Thule is, NASA will select a proper title to undergo the International Astronomical Union.
And regardless that missions have flown by the Kuiper Belt, thought-about the third zone of the photo voltaic system, they weren’t in a position to discover it as a result of scientists did not even learn about it till the 1990s.

“The Voyagers and Pioneers flew through the Kuiper Belt at a time when we didn’t know this region existed,” Jim Green, director of NASA’s Planetary Science Division, mentioned in an announcement. “New Horizons is on the hunt to understand these objects, and we invite everyone to ring in the next year with the excitement of exploring the unknown.”
The Kuiper Belt is stuffed with small, icy our bodies and worlds, and we do not know a lot about Ultima Thule. It was found in 2014 by the Hubble Space Telescope. In 2017, scientists decided that it is not spherical, however extra elongated. Ultima might even be two objects, however solely the flyby will inform for positive.

Based on its round orbit, versus the elliptical orbits of the planets, Ultima Thule fashioned four billion miles away in the midst of the Kuiper Belt. Temperatures listed below are near absolute zero as a result of the area is so removed from the solar. Ultima is 100 instances smaller than Pluto, and Pluto is in regards to the measurement of the United States.
And moderately than being like Pluto or the big planets in our photo voltaic system, Ultima Thule is a surviving planetary constructing block, primitive and pristine. It was by no means perturbed or moved, and it fashioned in an space the place ice is as sturdy and onerous as rock, so it by no means melted or fashioned a core. This will present perception about what it was like as our photo voltaic system was forming four.5 billion years in the past and the way small planets like Pluto fashioned.
The New Horizons mission was prolonged to watch Kuiper Belt objects after its Pluto flyby, with greater than two dozen Kuiper Belt objects on the listing. It may even measure the Kuiper Belt’s surroundings.
So what can we count on? As early as January 1, photos and information will likely be despatched again to Earth from New Horizons and its suite of devices and cameras about seven hours after that closest method.
After a “health status check” on the spacecraft, extra photos will begin to seem January 2 and within the first week of the brand new 12 months, which can inform whether or not Ultima Thule is sporting any rings, satellites or an environment. And we are able to study its composition.
“The Ultima Thule flyby is going to be fast, it’s going to be challenging, and it’s going to yield new knowledge,” Stern wrote on the New Horizons weblog. “Being the most distant exploration of anything in history, it’s also going to be historic.”
