New horizons of NASA will create its latest deep spacecraft

The outer solar system is the only place. A decade ago, though, a spacecraft was traveling from the Earth, but for a small city rock it was a little lonely in the New Year's Eve.

This single rock is called the Ultima Thule, and the purpose of the NASA's New Warston space ship from Pluto in July 2015. If scheduled, the historical flight will take place on January 1, 2019. "This is a far-reaching study of the history of the world," said Alan Stern, a senior fellow at the South West Research Institute in Texas. "It really sets a record."

At 6.6 billion km from the Sun, Ultima is found in the so-called Quercus belt on the outer corners of the Sun, a ring that is largely a stone and an ice-breaker. Planets in the Solar System. However, the Ultima is unusual because we believe it is there.

Other objects in the Kuiper belt that extend from 30 to 50 days (30 to 50 astronomical units or ABs) are located close to the planet before moving on. However, the Ultima emerged in the belt was a 4.6 billion-year-old purest material that survived our childhood. However, it is confident that its distance and its small size are hidden. We know very little about it, from the many telescopes of our data and the star's occultism – from the moment we walked past the stars and shaded the Earth.

We know that the object is red. We know this is about 30 miles (19 miles) away, and we know about ten percent of your kindergarten's dirt. "That's really," Stern says. "This is an open book compared to Pluto".

Ultima, which is 1.6 billion kilograms (1 billion miles) from Pluto, was chosen as the next goal for new horizons in August 2015. Originally called the Ultima Thule, called the 2014 MU69, "beyond the boundaries of a well-known world". The new horizons are planned to fly close to 3,500 kilometers (2,200 kilometers) away from Pluto. This group can be upgraded to 10,000 kilometers (6,000 miles), however, if the team finds any potential hazardous area near the oven.

The spacecraft will use seven vehicles and cameras for its pre-configured routine, regardless of distance, with a speed of 50,700 kilometers (31,500 miles) per hour.

One of the most interesting questions about Ultima Thule is its form. In our opinion, this binary is not two, but two objects – but whether these two objects are orbit with one another, or why they are not. The latter is called the Comet 67P-like binary connection, which is driven by the ESA's Rosetta spacecraft in 2014, but Ultima is about 1000 times more massive.

And we also know how much Ultima sees. We do not know how fast it will turn out, but this speed of rotation shows how much the object will illuminate as the new Objects pass. At 6.4 cycles of rotation, we saw only half of the sunshine brightness in Pluto. "If it's just a matter of hours, we'll love it," Stern says. "If this is a slower rotor, let's just be one day or more, and we'll get closer to the next day, and we do not know what the other side is."

The nearest approach to the spacecraft is scheduled for January 5 at 05.33. But the action will begin on December 31 and get the wrong image of the object from half a million to sixty pixels. miles away. It's enough to figure out Ultima's shape. Take a photo at night on January 1st, which is 10,000 pixels. January 2 is 40 thousand pixels. And in 2019, after downloading the original data, we have a great high-resolution image that is one megapixel.

During a 12-hour communication between the Earth and the spacecraft, the team took over the data that was transmitted according to the mission's basic scientific goals. Together with the latest data for September 2020, Pluto returns approximately 50 GB of data over the Earth for more than 20 months comparable to flyby.

The first group of data is the most important. This includes looking at the Ultima Thule surface, its surface content, and the search for small bearings or orbits. The following group 2 data includes the measurement of the object temperature and the search for any of the atmospheric conditions. Data coming from Group 3 is the last.

Even when these recent data come, the arrival may be flooded. The fact is that after September 2020, the team will consider the possibility of going to another facility in the Quarterín belt because of the remaining fuel consumption. The new horizons will leave this region until 2028, and the energy that will last up to 2038.

Prior to that, Ultima Thule has been paying close attention. And the team will hopefully pay all their work. "We tried and planned our hearts and hearts," says Stern. "But there is no backup. Do not go back and make U circulation. It's just a new horizons.
