NASA spacecraft survives risky encounter with faraway dark world | News

An unmanned NASA spacecraft has sent a signal back to Earth that it has successfully made it through a risky flyby past the most distant planetary object ever studied, the US space agency said on Tuesday.

NASA rang in the New Year with a historic flyby of the farthest, and quite possibly the oldest, cosmic body ever explored by humankind – a tiny, distant world called Ultima Thule – in the hopes of learning more about how planets took shape.

A series of anxiously awaited “phone home” signals arrived after 10:30am (15:30 GMT), indicating that the spacecraft had made it, intact, through the risky, high-speed encounter.
     
“We have a healthy spacecraft,” said Alice Bowman, missions operations manager for the New Horizons spacecraft, as cheers erupted in the control rooms at Johns Hopkins Applied Physics Laboratory in Maryland.

About 10 hours earlier, NASA celebrated the New Year’s flyby, at 12:33am (05:33 GMT) when the New Horizons spacecraft aimed its cameras at the space rock 6.4 billion km away in a dark and frigid region of space known as the Kuiper Belt.
     
Images and data will start arriving later Tuesday, offering scientists the first up-close look at an ancient building block of planets, Bowman said.



The flyby took place about a billion miles beyond Pluto, which was until now the most faraway world ever visited up close by a spacecraft.
     
Real-time video of the actual flyby was impossible, since it takes more than six hours for a signal sent from Earth to reach the spaceship, and another six hours for the response to arrive.
     
Hurtling through space at a speed of 51,200km an hour, the spacecraft aimed to make its closest approach within 3,520km of the surface of Ultima Thule.



Lead planetary scientist for New Horizons, Alan Stern, said Ultima Thule is unique because it is a relic from the early days of the solar system and could provide answers about the origins of other planets.
     
“The object is in such a deep freeze that it is perfectly preserved from its original formation,” he said.
   
“Everything we are going to learn about Ultima – from its composition to its geology to how it was originally assembled, whether it has satellites and an atmosphere and those kinds of things – are going to teach us about the original formation conditions of objects in the solar system.”

What does it look like?

Scientists are not sure what Ultima Thule looks like, whether it is cratered or smooth, or even if it is a single object or a cluster.

It was discovered in 2014 with the help of the Hubble Space Telescope, and is believed to be 19-32km in size.

A blurred and pixelated image released on Monday, taken from 1,920,000km away, has intrigued scientists because it appears to show an elongated blob, not a round space rock.

The spaceship was to collect 900 images over the course of a few seconds as it shaved by. Even clearer images should arrive over the next three days.

“Now it is just a matter of time to see the data coming down,” said deputy project scientist John Spencer of the Southwest Research Institute.

Scientists decided to study Ultima Thule with New Horizons after the spaceship, which was launched in 2006, completed its main mission of flying by Pluto in 2015, returning the most detailed images ever taken of the dwarf planet.

Stern said the goal is to take images of Ultima that are three times the resolution the team had for Pluto.

Ottawa transit commission hopes to prioritize COVID-19 vaccines for OC Transpo workers

Ottawa’s transit commission is pushing local and provincial health officials to recognize the role OC Transpo operators have played in keeping the city running during the COVID-19 pandemic, hoping to bump train and bus drivers in the vaccination queue amid a recent surge in coronavirus infections affecting transit workers.

More than 100 OC Transpo staff across the entire organization have tested positive for the coronavirus since the start of the pandemic, according to an update at Wednesday morning’s transit commission meeting.

Of those cases, 26 employees are currently recovering from the disease in self-isolation.

OC Transpo has seen a recent jump in COVID-19 cases, with Ottawa city council receiving reports of eight operators testing positive for the virus over a recent eight-day period.

Transit commissioner Sarah Wright-Gilbert attempted to find out how many of the total cases are traced to workplace transmission, but OC Transpo boss John Manconi said he’s been advised by medical officer of health Dr. Vera Etches that he can’t share that information for privacy reasons.

Transit operators are listed in the second priority group of essential workers as part of Ontario’s COVID-19 vaccine sequencing plans, but several commissioners speaking Wednesday wanted to get the city’s bus and train drivers bumped higher in the order.

Councillors Riley Brockington and Glen Gower both put forward motions looking to get front-line OC Transpo employees prioritization in vaccine sequencing, but others pointed out that the much-debated public health topic of who gets the vaccine and when is well beyond the scope of the transit commission.

“We are not in a position in transit commission to be decreeing, or making an edict, about what group of essential workers is more at risk than others and should be prioritized. That should be left up to public health experts,” Wright-Gilbert said.

Knoxdale-Merivale Coun. Keith Egli, who also chairs the Ottawa Board of Health, reflected on the board’s four-plus-hour meeting on Monday evening, during which vaccine sequencing and prioritizing essential workers dominated the conversation.

“Vaccine sequencing is obviously a very difficult maze to get through,” he said.

COVID-19: Ottawa police announce end of 24-7 presence at Ontario-Quebec border

Less than two days after the Ontario government’s latest COVID-19 restrictions came into effect, calling for non-essential traffic to be stopped at the province’s borders with Quebec and Manitoba, the Ottawa Police Service has announced it is stopping its 24-hour checkpoints.

According to a statement issued by the service Tuesday evening, the around-the-clock border checkpoints were set to end as of 8 p.m. on Tuesday in favour of rotating checkpoints across the city throughout the day until Ontario’s temporary regulations end.

“Since the onset of the border operations, the OPS has been working closely with Ottawa Public Health (OPH) along with local stakeholders and interprovincial stakeholders (the City of Ottawa, the City of Gatineau, the Ontario Provincial Police etc.) to assess any local public health, traffic and safety impacts. The assessment resulted in today’s operational changes,” the statement said.

“The operational changes announced today are designed to better ensure the health and safety of all, to minimize delays and/or hazards for travellers and to ensure essential workers can get to their places of employment on time.”

The statement also said the police service, while working to comply with the provincial order, was focused on education and enforcement actions that “support improved public health outcomes and respect the concerns of our most marginalized and racialized communities”

Officers said they will be conducting daily assessments on border crossings and that there could be further changes.

In a statement to Global News, a spokesperson for Solicitor General Sylvia Jones said that the border closures are ultimately subject to the discretion of local police enforcing the regulations.

“Local police services are best positioned to determine the operational deployments necessary to ensure the continued safety of their communities,” the spokesperson said, noting that the order’s regulations still apply to individuals entering the province.

The temporary order restricts Quebec residents from entering Ontario. If prompted, individuals must stop when directed by an enforcement officials and provide their reason for entering the province.

The main exemptions to the restrictions include if the person’s main home is in the province, if they work in Ontario, if they’re transporting goods, if they’re exercising Indigenous or treaty rights, if they need health care or if there’s a basis on compassionate grounds.

OTTAWA — Ottawa Public Health’s latest COVID-19 vaccination update shows that nearly half of all residents 60 to 69 years old have had at least one dose of a COVID-19 vaccine, a figure that has all but doubled in the past week.

OPH’s COVID-19 vaccination dashboard shows 58,000 residents 60 to 69 have had at least one dose of a COVID-19 vaccine, accounting for 49.3 per cent of that age group’s population in Ottawa. Last Wednesday, OPH reported 30,000 residents 60 to 69 had had at least one dose, which was 25.4 per cent.

As age demographics get younger, the population grows larger and the coverage by percentage may appear to grow more slowly, even if clinics are vaccinating greater numbers of people. For example, the latest figures show that 83 per cent of people aged 70 to 79 have had at least one dose. By raw population that’s 60,000 people, only slightly higher than half of all people in their 60s.

Vaccinations are open through the Ontario portal to anyone 60 and older and, this week, the AstraZeneca vaccine was approved for administration at pharmacies and primary care clinics to anyone in Ontario 40 and older.

OPH reported a new shipment this week of 25,740 doses of the Pfizer-BioNTech vaccine. To date, Ottawa has received 305,130 doses of COVID-19 vaccines from the provincial government.

The number of eligible residents (i.e. 16 and older) with at least one dose of a vaccine is now up to 28 per cent.

Tuesday was Ottawa’s second-busiest day for vaccinations overall, with the OPH reporting 9,729 shots administered. Last Friday saw 9,887 shots administered in a single day.
