Peterborough Public Health has declared a COVID-19 outbreak on Saturday (February 27) at Severn Court Student Residence in Peterborough.

Six cases have been confirmed so far at the 555 Wilfred Drive complex, which provides off-campus student housing primarily to Fleming College students, as well as students of Seneca College Aviation and Trent University. Approximately 200 students live in six separate buildings at the housing complex.

The index case has screened positive for a variant of concern, the health unit reports. Based on initial investigations, several of the exposures occurred during a private gathering that took place on Saturday, February 20th.

Medical officer of health Dr. Rosana Salvaterra has issued a Section 22 Order closing the housing complex to visitors and requiring all residents to self-isolate.

“This outbreak is very concerning not only because it involves a variant of concern and could lead to many more cases and high-risk contacts, but because it was also completely preventable,” said Dr. Salvaterra. “In spite of this difficult situation, Severn Court Management Company has been incredibly responsive and are working very hard to help us contain the spread of the virus.”

The health unit is asking anyone who visited Severn Court between Saturday, February 20th and Saturday, February 27th to self-isolate and get tested if they have COVID-19 symptoms, and is asking everyone is asked to stay away from the housing complex until further notice.

Peterborough Public Health is also working closely with Trent University and Fleming College.

The health unit says the specific variant of concern is not yet known while the sample undergoes further testing to identify its genomic sequence.

Contract tracing continues and further updates will be issued as more details become available.

To help chart the cosmos, Western space researchers turn to crowd sourcing – CBC.ca

Published

 on


Western University researchers have tapped the help of hundreds of amateur and professional astronomers in an effort to make sure no meteor is unable to slip by the Earth undetected.

To do that, they’re relying on the observations taken from 450 cameras in 30 different countries manned by “enthusiastic amateur astronomers” made up of professional and citizen scientists.

That data is then sent to Western University as part of what’s called the Global Meteor Network (GMN), headed by Denis Vida.

“So we have a lot of enthusiastic amateur astronomers, citizen scientists and also professionals that build, operate and maintain these cameras,” Vida told CBC’s Chris dela Torre during Afternoon Drive. “And every night they inspect the data set and send their data to a central server here at the University of Western Ontario.”

It’s not just about observing meteors – it’s about tracking what’s left of the ones that make it to the earth’s surface too.

“So we also observe a meteorite dropping fireballs,” said Vida. “They’re quite rare over an area of let’s say the country the size of France or Spain. Could only expect two to three of those fireballs a year that drop more than, let’s say, 300 grams of meteorites on the ground.”

“So because these events are very rare, it is important to observe 24/7.”

Vida explained that when one of their cameras spot one of them, they collect the data and find its location so they can retrieve what’s left for analysis – and analysis needs to happen quickly.  

“There are certain things in them, like some radionuclide to decay very quickly, but those can tell us how old the meteorite is, how long it was after it was ejected from the parent asteroid that it fell on the ground,” he said.

Vida explained that what ends up on the ground are just “several kilograms of materials” by the time they reach the earth’s surface. They aren’t hot either. They cool down on their descent.

Global push to monitor meteor showers led by Western University – CTV News London

Published

 on


MIDDLESEX CENTRE, ONT. —
London, Ont.’s Western University is leading a worldwide effort to monitor meteor showers and meteorite falls.

The Global Meteor Network (GMN) includes more than 450 cameras in 23 countries – hosted by amateur and professional astronomers.

The goal of the project, led by Denis Vida, a postdoctoral associate at Western, is to ensure unique or rare space events are not missed.

Vida explained in a statement, “Other astronomers can pool their resources to build a big telescope on top of a mountain where the skies are dark and clear year-round, but meteor astronomers need spatial coverage most of all.”

Meteors can occur anywhere in the world, happen close to earth and often burn up at around 100 km above the surface — so they can only be well observed from within about 300 km and need to be seen by cameras in at least two places to get the exact location.

That’s where the Global Meteor Network comes in.

In March, the network helped locate a rare portion of a meteorite that landed in Winchcombe, England on Feb. 28 and figure out where in space it originated.

“Its role in the recovery and analysis of the Winchcombe meteorite fall is proof positive that GMN works,” said Vida.

The first system to observe meteorites was installed at Western in 2017, and it continues to grow as the cost of meteor cameras has declined.

GMN also publishes the orbits of all observed meteors around the world within 24 hours of observation. The location of cameras and meteor data can be seen here.

The network also hopes to better understand flight patterns and flux capacities of meteorites, and even predict future events.

MDA gets $35.3 million contract from Canadian Space Agency for Canadarm 3 components – Times Colonist

Published

 on


BRAMPTON, Ont. — The Canadian Space Agency has awarded a contract worth $35.3 million to MDA Ltd. to design a key component of Canadarm 3.

The funds will be used to design Gateway External Robotics Interfaces or grapple fixtures for Canadarm 3, which is Canada’s contribution to the United States-led Lunar Gateway, a small space station that will orbit the moon.

The contract is a follow-on to the first phase of interface work awarded in August 2019. A construction phase will likely be awarded in about a year.

The first elements of Gateway will launch in 2024, with Canadarm 3 scheduled to launch two years later.

The contract is the third awarded to MDA for the multi-phase Canadarm 3 program valued at more than $1 billion.

Canadarm flew on 90 space shuttle missions after debuting in 1981. Canadarm 2 has been operating on the International Space Station for more than 20 years.

This report by The Canadian Press was first published July 26, 2021.
