Spacecraft opens new year with flyby on solar system’s edge

Published

LAUREL, Md. — NASA’s New Horizons spacecraft pulled off the most distant exploration of another world Tuesday, skimming past a tiny, icy object 4 billion miles from Earth that looks to be shaped like a bowling pin.

Flight controllers in Maryland declared success 10 hours after the high-risk, middle-of-the-night encounter at the mysterious body known as Ultima Thule on the frozen fringes of our solar system, an astounding 1 billion miles (1.6 billion kilometres) beyond Pluto.

“I don’t know about all of you, but I’m really liking this 2019 thing so far,” lead scientist Alan Stern of Southwest Research Institute said to applause. “I’m here to tell you that last night, overnight, the United States spacecraft New Horizons conducted the farthest exploration in the history of humankind, and did so spectacularly.”

The close approach came a half-hour into the new year, and 3 1/2 years after New Horizons’ unprecedented swing past Pluto.

For Ultima Thule — which wasn’t even known when New Horizons departed Earth in 2006 — the endeavour was more difficult. The spacecraft zoomed within 2,200 miles (3,500 kilometres) of it, more than three times closer than the Pluto flyby.

Operating on autopilot, New Horizons was out of radio contact with controllers at Johns Hopkins University’s Applied Physics Laboratory from late Monday afternoon until late Tuesday morning. Scientists wanted the spacecraft staring down Ultima Thule and collecting data, not turning toward Earth to phone home.

Mission operations manager Alice Bowman said she was more nervous this time than she was with Pluto in 2015 because of the challenges and distance, so vast that messages take more than six hours, one way, to cross the 4 billion miles (6.4 billion kilometres). When a solid radio link finally was acquired and team members reported that their spacecraft systems were green, or good, she declared with relief: “We have a healthy spacecraft.” Later, she added to more applause: “We did it again.”

Cheers erupted in the control centre and in a nearby auditorium, where hundreds more — still weary from the double countdowns on New Year’s Eve — gathered to await word. Scientists and other team members embraced and shared high-fives, while the spillover auditorium crowd gave a standing ovation.

Stern, Bowman and other key players soon joined their friends in the auditorium, where the celebration continued and a news conference took place. The speakers took delight in showing off the latest picture of Ultima Thule , taken just hundreds of thousands of miles before the 12:33 a.m. close approach.

“Ultima Thule is finally revealing its secrets to us,” said project scientist Hal Weaver of Johns Hopkins.

Based on the early, rudimentary images, Ultima Thule is highly elongated — about 22 miles by 9 miles (35 kilometres by 15 kilometres). It’s also spinning, although scientists don’t yet know how fast.

As for its shape, scientists say there are two possibilities.

Ultima Thule is either one object with two connected lobes, sort of like a spinning bowling pin or peanut still in the shell, or two objects orbiting surprisingly close to one another. A single body is more likely, they noted. An answer should be forthcoming Wednesday, once better, closer pictures arrive.

By week’s end, “Ultima Thule is going to be a completely different world, compared to what we’re seeing now,” Weaver noted.

Still, the best colour close-ups won’t be available until February. Those images should reveal whether Ultima Thule has any rings or moons, or craters on its dark, reddish surface. Altogether, it will take nearly two years for all of New Horizons’ data to reach Earth.

The observations should help scientists ascertain how deep-freeze objects like Ultima Thule formed, along with the rest of the solar system, 4.5 billion years ago.

As a preserved relic from that original time, Ultima Thule also promises to shed light on the so-called Kuiper Belt, or Twilight Zone, in which hundreds of thousands of objects reside well beyond Neptune.

“This mission’s always been about delayed gratification,” Stern reminded reporters. He noted it took 12 years to sell the project, five years to build it and nine years to reach the first target, Pluto.

Its mission now totalling $800 million, the baby grand piano-sized New Horizons will keep hurtling toward the edge of the solar system, observing Kuiper Belt Objects, or KBOs, from afar, and taking cosmic particle measurements. Although NASA’s Voyagers crossed the Kuiper Belt on their way to true interstellar space, their 1970s-era instruments were not nearly as sophisticated as those on New Horizons, Weaver noted, and the twin spacecraft did not pass near any objects known at the time.

The New Horizons team is already pushing for another flyby in the 2020s, while the nuclear power and other spacecraft systems are still good.

Bowman takes comfort and pleasure in knowing that long after New Horizons stops working, it “will keep going on and on.”

“There’s a bit of all of us on that spacecraft,” she said, “and it will continue after we’re long gone here on Earth.”

Border Patrol Agent Lashes Out At Biden-Harris Admin, Calling Job ‘Migrant Concierge Service’ Amid Border Crisis

Published on September 14, 2024

From the Daily Caller News Foundation

The border agent stated he is prepared to risk his career to bring attention to what he views as grave mismanagement and potential dangers posed by current border policies.

A Border Patrol agent criticized the recent changes in his role under the Biden-Harris administration, condemning it as transforming into a “migrant concierge service,” according to The New York Post Friday.

Zachary Apotheker, who joined the force in 2020, voiced his frustration over the shift in his duties under the Biden administration from intercepting drug traffickers and apprehending illegal entrants to what he now sees as aiding migrant entry, in an interview with the NYP. Apotheker highlighted concerns about security and vetting under President Joe Biden and Vice President Kamala Harris, noting that over 8 million migrants have crossed the southern border since January 2021, including members of the Venezuelan prison gang, Tren de Aragua.

“I don’t want to bring people into the country. That’s not what I signed up to do,” Apotheker told NYP. Apotheker’s distress is further compounded by over 1.7 million illegal migrants who have evaded capture since Jan. 2021, as he shared encounters with victims of migrant-committed crimes, naming individuals and emphasizing the personal toll on him.

“I’m an apolitical person and I just want to do my job and protect this country,” the agent said, the NYP reported. “When I see people from another country coming here, getting resources beyond what the American citizen can get, that’s where I have to draw the line. And then they’re going out and committing crimes and we’re still not removing them and American citizens are being killed, women are being raped.”

Apotheker and multiple Border Patrol sources have raised concerns to the NYP about the inadequate documentation for unaccompanied migrant children under 14, including missing biometric data, complicating their safe relocation to families or sponsors in the U.S. He highlighted a backlog in the immigration system, noting that 291,000 migrant children have been released in the U.S. without court dates, with an additional 32,000 failing to appear for their scheduled hearings.

The border agent stated he is prepared to risk his career to bring attention to what he views as grave mismanagement and potential dangers posed by current border policies. “However bad you think it is now, it’s only going to be worse,” he warned.

The White House and Border Patrol did not immediately respond to the Daily Caller News Foundation’s request for comment.

Rumored deal with Bloc Quebec party could keep Trudeau Liberals in power, stave off election

“The federal government does not have a mandate to bargain with Quebec separatists at the expense of Alberta, the West and the rest of the country”

The possibility of an early Canadian election may not come to fruition after Bloc Québécois leader Yves-Francois Blanchet hinted that an alliance between the separatist party and the Liberals under Justin Trudeau could become a reality.

Rumors began to swirl that a Bloc-Liberal deal could happen after Bloc House leader Alain Therrien said Sunday that the party’s “objectives remain the same, but the means to get there will be much easier.”

“We will negotiate and seek gains for Quebec … our balance of power has improved, that’s for sure,” he said, as reported by the Canadian Press.

Therrien made the comments in light of the possibility of a federal election taking place before fall 2025 after New Democratic Party leader Jagmeet Singh pulled his official support for Trudeau’s Liberals last week.

Late last month, Conservative Party leader Pierre Poilievre called on Singh to pull his support for Trudeau’s Liberals so that an election could be held.

Therrien also noted that the NDP pulling its support of the Trudeau Liberals has created a “window of opportunity” that his party may exploit. The Canadian Press reported that a person close to the Bloc party said directly that the NDP had in essence handed the party the balance of power.

As it stands now, the Bloc has 32 seats to the NDP’s 24, which is more than enough to prop up the Liberals, who have 154 seats.

As for Blanchet, he told the media on Monday that he was feeling “good” about his party’s newfound power. He then took a shot at Poilievre, saying he is more or less like Trudeau. “There are plenty of issues on which (Poilievre’s) in the same position as Justin Trudeau,” Blanchet said.

“Show us that you’re different, Justin Trudeau, apart from being against abortion, then we’ll see what you have to offer,” he said.

While most Conservative MPs are pro-life, Poilievre supports abortion and has a poor track record when it comes to life and family issues, with Campaign Life Coalition having given him a “red light” rating.

News of a possible Bloc-Liberal deal to keep Trudeau in power drew the immediate ire of Alberta Premier Danielle Smith.

“The federal government does not have a mandate to bargain with Quebec separatists at the expense of Alberta, the West and the rest of the country,” she wrote Monday on X. “If the Liberals go down this path, we need an election to be called immediately.”

On Tuesday, Blanchet responded to Smith’s comments to reporters by saying he found her remarks “funny,” adding that “Canadians are suddenly very interested in us.”

As for Trudeau, his woes continue to mount. LifeSiteNews recently reported how national elections campaign director for Canada’s federal Liberal Party announced he was stepping down because, according to sources close to the party, he does not think Trudeau can win a fourth consecutive election.

Recent polls show that the Conservatives under Poilievre would win a majority government in a landslide in an election held today. Singh’s NDP and Trudeau’s Liberals would lose a massive number of seats.
