A New Era of Lunar Exploration

For the first time in over half a century, humanity is preparing to return to the Moon, and Canada is playing a central role in this historic endeavor. The Artemis II mission, scheduled for a launch window beginning April 1, represents the first crewed flight to the lunar vicinity since the Apollo era. This 10-day fly-around mission will test the critical systems of the Orion spacecraft, paving the way for future permanent lunar habitats.

The First International Moon Traveler

At the heart of the mission is Colonel Jeremy Hansen, a 50-year-old veteran pilot from London, Ontario. Serving as a mission specialist, Hansen is set to make history as the first non-American to travel beyond low Earth orbit. A former CF-18 fighter pilot with extensive experience in Arctic operations and NORAD defense, Hansen joined the Canadian Space Agency in 2009. His role on Artemis II involves managing complex science and operational tasks alongside NASA astronauts Reid Wiseman, Victor Glover, and Christina Koch as they perform a lunar flyby and capture high-resolution imagery of the surface.

The Vital Role of the Backup

Supporting the mission from the ground—and ready to step in at a moment’s notice—is Calgary-born Jenni Gibbons. A former assistant professor at the University of Cambridge, Gibbons serves as Hansen’s backup. Her contribution extends far beyond potential flight; during the mission, she will serve as a ‘capcom,’ the primary voice link between Earth and the crew. Gibbons is also instrumental in defining training protocols for the future Artemis III and IV missions, ensuring that Canada remains a vital partner in the long-term goal of establishing a human presence on the Moon.

Looking Toward the Future

The success of Artemis II is the essential bridge to Artemis III, which will test docking capabilities with commercial landing craft. While NASA anticipates a return to the lunar surface by early 2028, the current mission serves as the ultimate proving ground for the technology and international cooperation required for deep-space exploration. For Canada, this mission is not just a scientific milestone, but a validation of the nation’s decades-long commitment to aerospace excellence.

A Personal Battle Becomes a Scientific Mission

Fifteen years ago, Vett Lloyd, a professor of biology at Mount Allison University, was told by public health officials that ticks simply did not exist in her home province of New Brunswick. Her own diagnosis with Lyme disease proved those claims false, sparking a career dedicated to understanding how these parasites are spreading across the Canadian landscape. Today, Lloyd’s research highlights a grim reality: tick populations and the diseases they carry are skyrocketing across the country.

The Role of Climate Change and Urban Development

The surge in tick activity is largely driven by shifting environmental factors. Traditionally, Canada’s long, harsh winters acted as a natural check on tick populations, starving them out as snow cover prevented them from finding hosts. However, global warming has led to more variable weather and less consistent snow cover. Ticks are opportunistic; they do not hibernate and will emerge to feed whenever temperatures rise, leading to much earlier and more intense seasons. Furthermore, the expansion of green, moist suburban areas has created the perfect habitat for rodents and other wildlife that carry ticks, bringing the threat directly into Canadian backyards.

The Hidden Scale of the Crisis

While official data from the Public Health Agency of Canada shows cases of Lyme disease rising from 143 in 2010 to over 7,000 by 2025, experts believe these numbers are a vast underestimation. Many cases go unreported due to a lack of diagnostic access or the difficulty of spotting a tick bite. Scientists estimate there has been a tenfold increase in infections over the last decade, with a significant portion of patients developing chronic illnesses that result in long-term fatigue, aches, and cognitive impairment.

New Threats on the Horizon

It isn’t just Lyme disease that Canadians need to worry about. Warmer regions like Southern Ontario are seeing the emergence of Lone Star and Gulf Coast ticks, which were previously unable to survive Canadian winters. These species can trigger ‘Alpha-gal syndrome,’ a severe red meat allergy caused by a reaction to tick saliva. As the climate continues to shift, researchers at Mount Allison University are working on rapid home-testing kits to help Canadians detect pathogens early and mitigate the growing economic and personal impact of these tick-borne illnesses.

A Rare Celestial Disappearance

Stargazers are in for a rare treat this June as Venus, the brightest planet in our night sky, is set to perform a dramatic vanishing act. On June 17, observers in specific regions of North and South America will witness a lunar occultation, a phenomenon where the Moon passes directly in front of Venus. This event effectively hides the planet from view before it re-emerges on the opposite side of the lunar disk, providing a unique opportunity to witness the celestial mechanics of our solar system in real-time.

The Planetary Parade

The occultation is only one part of a busy month for astronomical events. The first half of June features a stunning planetary conjunction between Venus and Jupiter. By June 9, these two ‘evening stars’ will appear remarkably close in the western sky. While they remain millions of miles apart in reality, their alignment along the ecliptic path makes them appear as a brilliant pair from our terrestrial vantage point. Between June 11 and 15, the elusive Mercury will join the duo, creating a triple-planet lineup low on the horizon just after sunset.

Welcoming the Summer Solstice

June also marks a pivotal point in Earth’s orbit: the summer solstice. Occurring on June 21 at 1:24 a.m. PT, the solstice signals the official start of astronomical summer in the Northern Hemisphere. This day provides the maximum amount of daylight for the year. Interestingly, while it is the longest day, it does not always align with the earliest sunrise or latest sunset due to the tilt and elliptical orbit of the Earth, a quirk of orbital mechanics that varies by latitude.

Deep-Sky Treasures Emerge

As the month progresses and the ‘Summer Triangle’—comprised of the stars Vega, Altair, and Deneb—rises into view, deep-sky observers can turn their attention to more distant wonders. This region of the Milky Way is home to iconic targets like the Dumbbell Nebula and the Ring Nebula. The Dumbbell Nebula, or Messier 27, was the first planetary nebula ever discovered and represents the glowing remains of a dying star. Whether you are watching a planet vanish behind the Moon or peering into the depths of a nebula, June offers a wealth of reasons to look up.

Investigation Sparked by Pediatric Cases

Health officials in British Columbia have confirmed the presence of invasive mosquitoes and a concerning virus capable of causing brain swelling in the Sea-to-Sky corridor north of Vancouver. The investigation was launched by the B.C. Centre for Disease Control (BCCDC) following a cluster of three pediatric encephalitis infections reported in the region in August 2024. Researchers concentrated their efforts between Squamish and Pemberton to identify the source of the rare infections.

California Serogroup Virus Identified

Anya F. Smith, a senior scientist with the BCCDC, stated that researchers discovered two mosquito species testing positive for the California serogroup virus. This group of pathogens is known to cause serious neurological conditions in humans, including encephalitis and meningitis. Among the carriers identified was the northern house mosquito, a species native to Africa, Asia, and Europe that has successfully established itself as an invasive species in British Columbia.

Impact of Climate Change on Disease Transmission

While the detected virus levels were low—preventing the team from confirming a specific strain—the findings are seen as a critical baseline for public health preparedness. Stefan Iwasawa of the BCCDC emphasized that rising temperatures due to climate change are expected to increase human exposure to various mosquito species. Understanding which species are present and what viruses they carry is essential for developing effective prevention and response strategies in a changing environment.

Assessing the Public Risk

Despite the detection, health authorities including Vancouver Coastal Health and the University of B.C. maintain that the current risk of serious illness remains low. Historical data shows only 15 known cases of California serogroup virus in B.C. between 2009 and 2024, with no new cases reported in the Sea-to-Sky corridor so far in 2025. Officials continue to monitor the situation while advising the public to take standard precautions against mosquito bites during the warmer months.
