The New Horizons spacecraft returns its most extreme types to Ultima Thule



The most detailed images of the Ultima Thule – obtained a few minutes before the closest approach to the spacecraft at 12:33 EST on January 1, with a resolution of approximately 110 meters per pixel. Their combination of higher spatial resolution and favorable viewing geometry gives an unprecedented opportunity to explore the Ultima Thule surface, which is considered to be the most primitive object ever encountered by a spacecraft. This processed, compiled image combines nine separate images taken from a Long Range X-Ray Recorder (LORRI), each with an exposure of 0.025 seconds, a mere 6½ minutes to the closest approach to Ultima Thule (officially named 2014 MU69). The image was taken at 5:26 UT on January 1, 2019, when the spacecraft was 4,109 miles (6,628 kilometers) from Ultima Thule and 4.1 billion miles (6.6 billion kilometers) from Earth. The angle between the spacecraft, Ultima Thule and the Sun – known as the "phase angle" – was 33 degrees.

The mission team called it the "purpose of stretching" – right before the approach, to precisely specify a camera on NASA's New Horizons spacecraft to capture the most distinct images of the Kuiper Belt object named " Ultima Thule ", his new year's target and the most distant subject ever investigated.

Now that New Horizons sends these saved images back to Earth, the team can enthusiastically confirm that its ambition has been fulfilled.

These new Ultima Thule images – obtained by the Longhorn Spot telephoto (LORRI) – in just a minute and a half before the closest New Horizons approach to the issue (officially named 2014 MU69) at 12:33 EST on January 1 – offer resolution of around 110 feet (33 meters) per pixel. Their combination of high spatial resolution and favorable viewing angle gives the team an unprecedented opportunity to explore the surface, as well as the origin and evolution of the Ultima Thule – considered the most primitive object ever encountered by the spacecraft.

"Bolsai!" said New Horizons chief researcher Alan Stern of the Southwestern Research Institute (SwRI). "Obtaining these images required us to know exactly where the tiny Ultima and the New Horizons were – instantaneously – when they passed each other for more than 32,000 miles an hour in the faint light of Koiper's belt, a billion miles beyond Pluto." A much more rigorous observation than all that we tried on our flight in 2015.

"These observations of" stretching the target "were risky, because there was a real chance that we would get only a part or even none of Ultima in the narrow field of the camera. "Continuation," he continued. – But the scientific, operational and navigational teams have succeeded him, and the result is a field for our team on science! Some details we now see on the surface of Ultima Thule, unlike any objects that have ever been investigated before. "




Scientists from New Horizons have created this film from 14 different images taken loyal (LORRI). On January 1, 2019, a Kuiper Belt named Ultima Thule (officially named 2014 MU69) was launched. The central frame of this sequence was made on January 1 at 5:26:54 UT (12:26 am EST), when New Horizons was 4,117 miles (6,640 kilometers) from Ultima Thule, about 4.1 billion kilometers from the Earth Ultima Thule almost completely fills the image of LORRI and great flair in the spectacular feat, given the uncertain location of Ultima.

This is not evident in previous images. Among them are several bright, mysterious, approximately round areas of the area. In addition, many small, dark pits near the terminator (the boundary between the sunshine and the dark sides of the body) are better resolved. "Whether these functions are craters made by drummers, submersible pits, holes for destruction, or something completely different, is discussed in our research team," said John Spencer, deputy scientist at SwRI.

Johns Hopkins Laboratory for Applied Physics has noted that the latest images have the highest spatial resolution of any New Horizons taken – or ever taken – throughout their mission. The new horizons flew about 2,200 miles (3,500 kilometers) approximately three times closer to Ultima than in its first mission, Pluto, in July 2015.

Ultima Thule is less than Pluto, but Ultima flyby was made with the highest accuracy of navigation achieved by any spacecraft. This unprecedented accuracy was achieved through 2017 and 2018 land-engagement campaigns conducted in Argentina, Senegal, South Africa and Colombia, as well as in the mission of the European Space Agency Gaia, which provided the location of the stars used during

New Horizons – almost 4.13 billion kilometers from Earth; At this distance, radio signals moving at light speeds reach the large antennas of the Deep Space Network NASA six hours and nineteen minutes after New Horizons sends them.
