Canada will for the first time send an astronaut to circle the moon on a US mission planned for 2023, Innovation Minister Navdeep Bains said on Wednesday, announcing a formal deal with Washington.
US Vice President Mike Pence last week unveiled an 18-strong pool of people who could go to the moon under NASA’s Artemis program, which Canada is now a part of.
Artemis is designed to send several missions to the Moon. The Canadian astronaut – who has yet to be named – will take part in the second trip, which is scheduled to fly around the moon on a 10-day journey in 2023.
“All eyes will look to the sky as one of our astronauts becomes the first Canadian to travel around the moon,” Bains told a news conference.
Canada and the United States have a long history of cooperation in space. Bains also said a Canadian astronaut would one day fly to the Lunar Gateway, an outpost NASA plans to build that will orbit the moon sometime within the next decade.
Canada built the Canadarm robotic arms which were initially installed on some of the US space shuttles and then the International Space Station. Canada has already signed a deal to build a new Canadarm for the Lunar Gateway.
The United States aims to put an astronaut on the moon in 2024. Some in the US space agency and American space industry view this as unrealistic and the target could well be pushed back after President-elect Joe Biden takes office on Jan. 20.
The last astronauts to actually tread on the moon were the crew of Apollo 17 in December 1972.

Hearing the dead person? Here’s what research says – Tech Explorist
Why some people and not others say they receive communications from ‘the dead’?
This is horrifying. Right?
But why this happens?
A new study by Durham University explains the reason. The study found that spiritualist mediums might be more prone to immersive mental activities and unusual auditory experiences early in life.
Spiritualism is a religious movement dependent on the possibility that human spirits keep on existing after death and speak with the living through a medium or psychic.
A medium that hears the dead person is believed to be experiencing clairaudient communications instead of clairvoyant (“seeing”) or clairsentient (“feeling” or “sensing”) communications.
The study involved 65 clairaudient spiritualist mediums from the Spiritualists’ National Union and 143 members of the general population.
Spiritualist mediums completed an online questionnaire assessing the timing, nature, and frequency of their auditory (clairaudient) spiritual communications – including scales measuring paranormal beliefs, absorption, hallucination-proneness, and aspects identity. These measures were compared to a general population group.
They found that these spiritualists have a strong leaning towards absorption – a trait linked to immersion in mental or imaginative activities and altered states of consciousness.
Eighteen percent revealed having clairaudient experiences ‘for as far back as they could recall’, and 71 percent had not experienced Spiritualism as a religious movement preceding their first experience.
Numerous who experience hearing dead voices experience spiritualist beliefs while looking for the meaning behind, or heavenly significance of, their own and unusual experiences.
Spiritualists tend to report unusual auditory experiences that are positive, start early in life and are often then able to control.
Understanding how these develop is important in helping us learn more about distressing or non-controllable experiences of hearing voices and how to support those whose voices are linked to psychosis or other mental health problems.

Three more COVID-19 cases at GRT – KitchenerToday.com
Grand River Transit is confirming three more COVID cases.
All the affected employees are bus drivers.
Two of them last worked on January 15, while the third was last on the job on Jan. 11.
GRT points out all three are now self-isolating at home.
So far in Janaury, nine employees have tested positive for the virus.
Grand River Transit lists COVID-19 cases on its website for transparency purposes, but some details are not released due to privacy concerns.
Since the on-set of the pandemic, multiple safety precautions have been put in place to protect drivers and riders, including barriers and mandatory masks.
Microplastics could be eliminated from wastewater at source – E&T Magazine
A team of researchers from the Institut national de la recherche scientifique (INRS), Quebec, Canada, have developed an electrolytic process for treating wastewater, degrading microplastics at the source.
Microplastics are fragments of plastic less than 5mm long, often contained in toiletries or shedding from polyester clothing. They are present in virtually every corner of the Earth, and pose a particularly serious threat to marine ecosystems. High concentrations of microplastics can be carried into the environment in wastewater.
There are no established degradation methods to handle microplastics during wastewater treatment; although some techniques exist, these involve physical separation as a means of filtering the pollutant. These techniques do not degrade microplastics, which requires additional work to manage the separated fragments. So far, research into degradation of microplastics has been very limited.
The INRS researchers, led by water treatment expert Professor Patrick Drogui, decided to try degrading plastic particles through electrolytic oxidation – a process that does not require the addition of chemicals.
“Using electrodes, we generate hydroxyl radicals to attack microplastics,” Drogui said. “This process is environmentally friendly because it breaks them down into CO2 and water molecules, which are non-toxic to the ecosystem.”
Drogui and his colleagues experimented with different anode materials and other parameters such as current intensity, anode surface, electrolyte type, electrolyte concentration and reaction time. They found that the electrolytic oxidation could degrade more than 58 ± 21 per cent of microplastics in one hour. The microplastics appeared to degrade directly into gas rather than breaking into smaller particles.
Lab-based tests on water artificially contaminated with fragments of polystyrene showed a degradation efficiency as high as 89 per cent.
“This work demonstrated that [electrolytic oxidation] is a promising process for degradation of microplastics in water without production of any waste or by-products,” the researchers wrote in their Environmental Pollution report.
Drogui envisions this technology being used to treat microplastic-rich wastewater emerging from sources such as commercial laundries.
“When this commercial laundry water arrives at the wastewater treatment plant, it is mixed with large quantities of water, the pollutants are diluted and therefore more difficult to degrade,” he explained. “Conversely, by acting at the source, i.e. at the laundry, the concentration of microplastics is higher, thus more accessible for electrolytic degradation.”
Next, the researchers will move on to experimenting with degrading microplastics on water outside the artificial laboratory environment. Real commercial laundry water contains other materials that can affect the degradation process, such as carbonates and phosphates, which can trap radicals and limit degradation. If the technology is effective under these circumstances, the researchers plan to conduct a study to determine the cost of scaling up this treatment to implement in laundries.
Last week, researchers from the University of Barcelona published a study suggesting that encouraging a greater proliferation of seagrass meadows in the shallows of oceans could help trap, extract and carry marine plastic debris to shore.
