Satellites in a Train

Satellites in a Train

Winnipeg residents have been reporting some unusual sightings in the night sky over the past few days. Bright star-like objects have been seen moving across the sky, following each other in a train. Sometimes half a dozen or more of them are visible at the same time. What are these?

Unfortunately, they won’t be “unusual” for very long. These are the StarLink satellites, launched by Elon Musk’s Space-X to deliver internet to remote corners of the globe. 60 satellites at a time are put up by the company’s Falcon-9 rocket, and they slowly spread out in a circle around the earth. For the first couple of weeks after launch, they are relatively close together, and all appear to travel in the same path across the sky. As of today, there are 362 of these satellites, but the plan is for 12,000 of them. As in, twice as many satellites as the number of stars you could see from a perfectly dark location.

And did we mention that each one is one of the brightest objects in the sky? They shine at about magnitude 1 or brighter, which means they’re brighter than the stars of the Big Dipper and as bright as the brighter stars. Only the planets and the moon, and maybe a few stars, will outshine a StarLink satellite.

It’s pretty easy to spot these satellites when they happen to be going over your town. Visit www.heavens-above.com and set it to your location, and you’ll get a list of all of the satellites visible that night. StarLink will make up a big chunk of that list. For example, from Winnipeg between 9:25 pm and 9:45 pm on Monday night, March 30, there will be 44 StarLink satellites visible (plus a few other satellites). The sky is getting to be a busy place!

StarLink has brought criticism from astronomers, who are already finding interference with the satellites getting into their field-of-view while trying to do science. Those concerned with the amount of space junk in orbit are also concerned, as none of these satellites has a re-entry plan and will just stay up there, cluttering orbit and posing a risk to any other satellites launched, including any attempts to send robots or humans to the other planets. We’re basically building a cage around the Earth, with StarLink satellites as the bars.

Fowlie Collection Homecoming

Throughout its history, the Hudson’s Bay Company had a tradition of recruiting young men from Scotland to serve as clerks, traders, and labourers in its North American posts, offering both adventure and security of employment. Housing and basic needs were covered, but luxuries like sugar, tea, tobacco, and brandy were bought from the post by the men themselves and deducted from their wages. Commerce didn’t stop at the four walls of the post; these men frequently acquired handmade objects from Indigenous women in the communities they lived in, both for their personal use and to send home as gifts for loved ones. Since arriving at the Manitoba Museum, the Hudson’s Bay Company Museum Collection has received donations of these objects from former HBC employees and their descendants, highlighting the skilled work of Indigenous women across Canada. By and large, unfortunately, we lack information on these artisans and turn to our collection for answers – using other objects with similar breading or embroidery styles and techniques that have more robust records, we can often identify which cultures or communities may have produced specific objects.

In the summer of 2018, we received a package from Scotland, full of objects, photographs, and documents that told the story of an HBC employee in northern Manitoba in the 1920s. By the 1920s, HBC was more rigorous in their recruiting process. As opposed to “just showing up” like days of yore, men needed to present personal and professional references and pass a physical examination before being offered a contract. Our new acquisition had all these documents and more…but who was this intrepid young Scot that sailed across the Atlantic to the unknown?

Born May 25, 1902 in Aberdeen, Scotland, George Fowlie lost his father at a young age. After finishing school at Robert Gordon’s College in 1917, he worked at North of Scotland and Town & Country Bank. In 1923, when he entered into service on a five-year contract with the Hudson’s Bay Company as an apprentice clerk at York Factory in HBC’s Nelson River District. We have no concrete evidence as to why Fowlie decided to join HBC or leave the bank; his references were glowing- but his daughter suggested that he was single and looking for adventure. Fowlie made the most of his time at York Factory. He traded his desk job for a cariole and dog whip as Fowlie worked with dog sled teams, creating strong bonds with his canine colleagues. He also formed a tight knit community with his fellow Scotsmen, enjoying music played on the gramophone and partaking in the culture of York Factory, which include socializing and working with the Indigenous community in the area.

Fowlie documented his experiences and the people at York Factory through photography, including his work mates, his dogs, himself playing with local children and sharing a laugh with young women in front of the Anglican Church.

These candid images of HBC employees, local Indigenous peoples and the buildings and landscape also give us a rare glimpse at HBC’s working class and a real idea of what life was like for the community at York Factory.

Fowlie also carefully preserved the beloved handmade objects he likely acquired from Cree or Métis women during his tenure at the post –some that he used in his everyday life such as moccasins and gauntlet gloves and some that he sent back to Scotland as gifts for his mother, a number of wall pockets and a beaded belt.

Upon leaving the HBC, Fowlie returned to Scotland and worked as a chauffeur until WWII. Following his service in WWII as clerk in the Royal Air Force, he married Madge Briggs and had daughter Marjorie in 1947. When Fowlie passed away in 1985, his HBC collection was passed down to Marjorie, who appreciated the historical significance of her father’s objects. She decided to donate the collection to the Manitoba Museum, but not before making a quick stop on Antiques Roadshow to showcase these beautiful pieces, and allowing them to be researched and exhibited by the University of Aberdeen. Thanks to George Fowlie and his family’s care, these objects have officially made their Manitoba homecoming.

If a Tree Falls in the Forest

An orange mushroom growing in dark damp earth near sticks, pinecones, and rotting leaves.

We humans tend to think that diseases affect only animals but plants suffer from them as well. Diseases are caused by microscopic animals (like parasitic worms), fungi, bacteria and viruses and they affect animals, plants, fungi and even some species of bacteria (viruses that infect bacteria are called bacteriophages). But it’s not just microorganisms that parasitize species; larger organisms do too. Some fungi are parasites of other fungi and some plants are parasites of other plants. One good example that you may have encountered while going for a walk in the woods is the Lobster Mushroom (Hypomyces lactifluorum). This species of fungus parasitizes other fungi, often the mushrooms of milk-caps (e.g. Lactarius), distorting the shape and resulting in the bright orange colour. Although some people enjoy eating these mushrooms, they could be poisonous if the mushroom that was parasitized was poisonous.

Another common parasite you may have encountered is Dwarf Mistletoe (Arceuthobium spp.). Mistletoes parasitize trees such as white spruce (Picea glauca), causing strange broom-shaped branches, often called “witches-brooms”. Mistletoes are actually flowering plants that cannot photosynthesize. Instead, they have modified roots that can tap into the vascular systems of other plants to steal their sap. To disperse their seeds, the fruits build up hydrostatic pressure, and then shoot the seeds into the air at speeds of up to a spectacular 80 km per hour! The seeds are covered in a gluey substance, which helps them stick to the bark of trees. The germinating seed sends its roots into the tree bark instead of the soil.

Parasites and diseases are what population ecologists call density-dependent causes of mortality; factors that only affect an individuals’ survival when populations are at high densities. Other density-dependent factors affecting plant survival include: competition for resources, such as water, light and soil minerals, and intense herbivory (usually by insects). In general, density-dependent causes of mortality are biotic, that is, caused by other organisms. Density-independent factors of mortality are usually abiotic (not alive) or environmental: forest fires, drought and volcanic eruptions that bury vegetation in lava are a few examples.

There are plenty of plant parasites and diseases that evolved right here in North America. However, most native plants have evolved methods to resist these organisms to some degree so it is not always fatal to the plant, unless it is in a weakened state. During droughts for example, trees are much more likely to die of a disease. Since the colonization of North America occurred, species of diseases that were not native to this continent have been accidentally introduced, typically with dire consequences. In my next blog, I will be discussing how three species of native Canadian trees (American Chestnut, American Elm, and Green Ash) are being negatively impacted by introduced diseases, and how we can change our behaviour to protect our forests, both wild and urban.
