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

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.”

Taxpayers Federation calling on BC Government to scrap failed Carbon Tax

Published on January 16, 2025

Todayville

From the Canadian Taxpayers Federation

By Carson Binda

BC Government promised carbon tax would reduce CO2 by 33%. It has done nothing.

The Canadian Taxpayers Federation is calling on the British Columbia government to scrap the carbon tax as new data shows the province’s carbon emissions have continued to rise, despite the oldest carbon tax in the country.

“The carbon tax isn’t reducing carbon emissions like the politicians promised,” said Carson Binda, B.C. Director for the Canadian Taxpayers Federation. “Premier David Eby needs to axe the tax now to save British Columbians money.”

Emissions data from the provincial government shows that British Columbia’s emissions have risen since the introduction of a carbon tax.

Total emissions in 2007, the last year without a provincial carbon tax, stood at 65.5 MtCO2e, while 2022 emissions data shows an increase to 65.6 MtCO2e.

When the carbon tax was introduced, the B.C. government pledged that it would reduce greenhouse gas emissions by 33 per cent.

The Eby government plans to increase the B.C. carbon tax again on April 1, 2025. After that increase, the carbon tax will add 21 cents to the cost of a litre of natural gas, 25 cents per litre of diesel and 18 cents per cubic meter of natural gas.

“The carbon tax has cost British Columbians a lot of money, but it hasn’t helped the environment as promised,” Binda said. “Eby has a simple choice: scrap the carbon tax before April 1, or force British Columbians to pay even more to heat our homes and drive to work.”

If a family fills up the minivan once per week for a year, the carbon tax will cost them $728. The carbon tax on natural gas will add $435 to the average family’s home heating bills in the 12 months after the April 1 carbon tax hike.

Other provinces, like Saskatchewan, have unilaterally stopped collecting the carbon tax on essentials like home heating and have not faced consequences from Ottawa.

“British Columbians need real relief from the costs of the provincial carbon tax,” Binda said. “Eby needs to stop waiting for permission from the leaderless federal government and scrap the tax on British Columbians.”

The problem with deficits and debt

Published on January 13, 2025

From the Fraser Institute

By Tegan Hill and Jake Fuss

This fiscal year (2024/25), the federal government and eight out of 10 provinces project a budget deficit, meaning they’re spending more than collecting in revenues. Unfortunately, this trend isn’t new. Many Canadian governments—including the federal government—have routinely ran deficits over the last decade.

But why should Canadians care? If you listen to some politicians (and even some economists), they say deficits—and the debt they produce—are no big deal. But in reality, the consequences of government debt are real and land squarely on everyday Canadians.

Budget deficits, which occur when the government spends more than it collects in revenue over the fiscal year, fuel debt accumulation. For example, since 2015, the federal government’s large and persistent deficits have more than doubled total federal debt, which will reach a projected $2.2 trillion this fiscal year. That has real world consequences. Here are a few of them:

Diverted Program Spending: Just as Canadians must pay interest on their own mortgages or car loans, taxpayers must pay interest on government debt. Each dollar spent paying interest is a dollar diverted from public programs such as health care and education, or potential tax relief. This fiscal year, federal debt interest costs will reach $53.7 billion or $1,301 per Canadian. And that number doesn’t include provincial government debt interest, which varies by province. In Ontario, for example, debt interest costs are projected to be $12.7 billion or $789 per Ontarian.

Higher Taxes in the Future: When governments run deficits, they’re borrowing to pay for today’s spending. But eventually someone (i.e. future generations of Canadians) must pay for this borrowing in the form of higher taxes. For example, if you’re a 16-year-old Canadian in 2025, you’ll pay an estimated $29,663 over your lifetime in additional personal income taxes (that you would otherwise not pay) due to Canada’s ballooning federal debt. By comparison, a 65-year-old will pay an estimated $2,433. Younger Canadians clearly bear a disproportionately large share of the government debt being accumulated currently.

Risks of rising interest rates: When governments run deficits, they increase demand for borrowing. In other words, governments compete with individuals, families and businesses for the savings available for borrowing. In response, interest rates rise, and subsequently, so does the cost of servicing government debt. Of course, the private sector also must pay these higher interest rates, which can reduce the level of private investment in the economy. In other words, private investment that would have occurred no longer does because of higher interest rates, which reduces overall economic growth—the foundation for job-creation and prosperity. Not surprisingly, as government debt has increased, business investment has declined—specifically, business investment per worker fell from $18,363 in 2014 to $14,687 in 2021 (inflation-adjusted).

Risk of Inflation: When governments increase spending, particularly with borrowed money, they add more money to the economy, which can fuel inflation. According to a 2023 report from Scotiabank, government spending contributed significantly to higher interest rates in Canada, accounting for an estimated 42 per cent of the increase in the Bank of Canada’s rate since the first quarter of 2022. As a result, many Canadians have seen the costs of their borrowing—mortgages, car loans, lines of credit—soar in recent years.

Recession Risks: The accumulation of deficits and debt, which do not enhance productivity in the economy, weaken the government’s ability to deal with future challenges including economic downturns because the government has less fiscal capacity available to take on more debt. That’s because during a recession, government spending automatically increases and government revenues decrease, even before policymakers react with any specific measures. For example, as unemployment rises, employment insurance (EI) payments automatically increase, while revenues for EI decrease. Therefore, when a downturn or recession hits, and the government wants to spend even more money beyond these automatic programs, it must go further into debt.

Government debt comes with major consequences for Canadians. To alleviate the pain of government debt on Canadians, our policymakers should work to balance their budgets in 2025.
