NASA's New Horizons nuclear space arrives at Ultima Thule in New Year's Eve



Spaceships near Pluto will be exploring new years by exploring a more distant and mysterious world.

NASA's New Horizons Space Station will freeze the nickname Ultima Thule (TOO-lee) from midnight onwards.

Over one million million Pluto and 4 billion million Earth (1,600 million kilometers and more than 6.4 million kilometers), Ultima Thule is the world's largest explorer. That is so brilliant that it is so deeply frozen that purpose; The relic is preserved, which originated from our solar system 4.500 million years ago. No spacecraft visited anything so primitive.

"What is more than exciting?" The Weaver Project by John Weaver Hopkins University, New Horizons.

The scientific director of the Southwest Research Institute, Boulder, Colorado, is expected to be more complicated than a New Year's encounter and compared to Pluto: the space ship is older, the target is small, the flyby is closer and our distance is higher.

New Horizons
NASA launched its nuclear program in 2006; The baby is the size of a grand piano. Pluton passed in 2015, offering the nearest approaches to dwarf planet. Succeeding in the success of foreign aircraft, mission planning wins a NASA extension and set a deep Kuiper Belt destination. Pluton is far removed from the Kuiper Belt, called Twilight Zone, beyond Neptune. Ultima Thule is at the heart of Twilight Zone.

Last Thule
This Kuiper ring was discovered by the Hubble Space Telescope in 2014. In 2014, known as MU69, Ultima Thule got an online nickname. In classical and middle-class Literature, Thule was one of the most remote places in the world. When New Horizons saw the amazing icebergs in August, it was just one point. Good photo photographers will be available after the flyby.

Are you still there?
New Horizons will take the closest approach on January 1 – 12:33 p.m. EST. Spatial ships will have 2,200 miles (3,500 km) of Ultima Thule length, making seven major scientific instruments. The coast must be clear: scientists have not yet found the ring or moon that could have piled the nucleus. New Horizons escapes to 31,500 mph (50,700 km / h) in space and can be as small as rice grain. "There are some risks and suspicious ones," said Stern in a fall of the astronomers meeting. It will take about 10 hours for a meeting and survival of the spacecraft.

Maybe twins
Scientists speculate that Ultima Thule could be two objects that orbit each other. If he is a soloist, he will have a maximum length of 20 km (32 km). See baked potatoes. "Pepino, whatever. Choose your favorite vegetable," said Johny Hopkins at the Carey Lisse astronomer. They could also be two limbs connected to the neck. If there are two twins, each may be 9 kilometers in diameter 12 kilometers (15 kilometers and 20 kilometers).

Mapping Mission
Scientists will give the Ultima Thule map as much as possible. Impact craters are foreseen, perhaps wells and holes, but the surface can also be smooth. In terms of colors, Ultima Thule must be darker than coal, because they burn with cosmic rays with a reddish hue. Nothing is certain, however, that its orbit, so large, has nearly 300 Earth years around the sun. Scientists say they say they hinder enough.

Comparing Flybys
New Horizons will reach the Ultima Thule in Pluto: 2,220 miles versus 7,770 miles (3,500 kilometers and 12,500 kilometers). At the same time, Ultima Thule is 100 times smaller than Pluto, so it is harder to track everything challenging. He lasted four and a half hours in each way to send a message to Pluton's New Horizons at the Johns Hopkins Applied Physics Lab in Laurel, Maryland Aircraft Controllers. Compare Ultima Thule for more than six hours.

What's next?
New Horizons every two years includes all the latest Thule data. They would leave a farthest world in 2020, if NASA supports another mission extension and if the spacecraft is still healthy. At least, the power of the New Horizons nuclear will continue to observe remotely objects, as it is deepening in the depth of the Kuiper Belt. There are many objects waiting to be analyzed.
