Discover Québec scientists focusing on the world's most remote exploration of the planet's history



MONTREAL – Frederic Pelletier foresees that he and his team will be the Space New Horizons spacecraft specifically in the New Year's Day, with more than 1.6 million kilometers of Pluto, with a rock space called Ultima Thule.

NASA's mission is to overcome the region known as the "Ring of the Kuiper" and send out Earth's data to explain the origin of the solar system. Ultima Thule's plane is describing the space agency as the farthest exploration of any body in the history of the planet. "

According to what NASA explores in the Pluton region, scientists can get more information about comets, planets, and other materials when they plan on the planet – 4.5 million years ago.

When the New Horizons spacecraft reaches the closest approach to Ultima Thule – at standard hours of the Sun at 12:33 a.m. from January 1 to 2019 – it will be a 6.6-mile-long vehicle for Earth.

"It's very difficult, we do not have too much information (Ultima Thule)," said Pelletier in a recent interview with the Canadian press. "I'm somewhat nervous, but I'm sure … all the stars are aligned."

NASA Pelletier named the main navigator of the New Horizons spacecraft mission, which was the original plane in Pluto. The group managed to reach the finish line on a plane dwarf plane on July 14, 2015, and "detailed data on Pluton and its new moon views" on the expedition's website.

The journey from Pluton to Kuiperra is part of the extended mission.

Pelletier and its eight members have delivered the spacecraft, which is the size of a grand piano for children.

Ultima Thule will fly to a distance of 3,500 kilometers, 14 kilometers per second or 50,000 kilometers per hour. Pelletier compared a conductor inside a car trying to find a lamppost.

"It's really fast doing," he said.

Pelletier scientists estimate that Ultima Thule is Washington D.C.

"It is expected to be 30 km in diameter today," Pelletier said. "We suspect that it will not be spherical, it will have a curious shape like this, it will be a binary asteroid in a touch or close formation of two objects."

What has the question of Québécoen's birth to question even more? In fact, the signal of the Earth takes six hours to reach the spacecraft and return another six hours.

"So we must take into account the maneuver planning summits and updates," said Pelletier.

The New Horizons spacecraft unexpectedly took place on January 19, 2006, and went on to explore Pluton and expanded it from 2015 onwards. The mission located at the Applied Laboratory of Laurel Laboratory at the Johns Hopkins University Laboratory is being carried out by Pelletier and his team.

Ultima Thule was detected for the first time in 2014 using the Hubble Space Telescope, and after launching New Horizons they discovered a new rock.

NASA says scientists have hundreds of objects with a diameter of more than 30 kilometers in length, awaiting what is called the "third zone" of the solar system.

"I'm an explorer," Pelletier said. "I love spots (not explored) on the edge of the solar system. The Kuiper Belt was only found in the 1990s."

Until January 1, Pelletier will monitor Ultima Thule to celebrate its 44th birthday on Wednesday, December 28.

But his wife and two boys, ages 9 to 12, will go to Maryland to join in the coming days.

Pelletier worked on other space missions, when he traveled to space Saturnin Cassini and also attended Mars Curiosity.
