Entering an Era of Black Hole Discovery
Presented by: Dr. Daryl Haggard, McGill University Department of Physics/McGill Space Institut
Date & Time: April 8th, 2022 | 12:30 - 1:30 PM ET

It’s been a fantastic decade for black hole studies, highlighted by the 2017 and 2020 Nobel Prizes in Physics. Multiple Galactic Center research groups, the Event Horizon Telescope, and LIGO/Virgo continue to bring rapid-fire new observations to sharpen our understanding of these exotic objects. I will discuss Sgr A*’s unique variability alongside other time domain phenomena in the Galactic Center, traced out over more than 20 years of observations from coordinated multi-wavelength campaigns. I will compare these detailed studies of Sgr A* to equally impressive multi-wavelength observations of M87*. I will also briefly explore how we can continue to push the frontiers of black hole research with existing and next-generation observatories.

October 22nd 2021 - The Twinkle Space Mission: an update on the international collaborative exoplanet survey

Speaker: Max Joshua

The Twinkle Space Mission is a space-based observatory that has been conceived to measure the atmospheric composition of exoplanets, stars and solar system objects. Twinkle’s collaborative multi-year global survey programs will deliver visible and infrared spectroscopy of thousands of objects within and beyond our solar system, enabling participating scientists to produce world-leading research in planetary and exoplanetary science. Twinkle’s growing group of international Founding Members have now started shaping the survey science program within focused Science Teams and Working Groups and will soon be delivering their first publications.

Twinkle will have the capability to provide simultaneous broadband spectroscopic characterisation (0.5–4.5µm) of the atmospheres of several hundred bright exoplanets, covering a wide range of planetary types. It will also be capable of providing phase curves for hot, short-period planets around bright stars targets and of providing ultra-precise photometric light curves to accurately constrain orbital parameters, including ephemerides and TTVs/TDVs present in multi-planet systems. This talk will present an overview of Twinkle’s mission status and discuss some example exoplanet surveys to highlight the broad range of targets the mission could observe, demonstrating the scientific potential of the spacecraft. It will also report on the work of Twinkle’s Exoplanet Science Team, which is formed of researchers from across the globe, including the University of Toronto, showcasing their science interests and the studies into Twinkle’s capabilities that they have conducted since joining the mission.

October 29th 2021 - Deep Ocean circulation history from sediments

Speaker: Dr. Brian Romans

Dr. Brian Romans is an associate professor in the Department of Geosciences at Virginia Tech. He received his Ph.D. in Geological & Environmental Sciences from Stanford University, M.S. in Geology & Geological Engineering from Colorado School of Mines, and undergraduate degree in Geology from SUNY Buffalo. Brian has participated as a shipboard scientist on two IODP Expeditions (Expeditions 342 and 374).

Abstract: Ocean circulation plays a critical role in the Earth’s climate system through the storage and transfer of heat and carbon dioxide. The North Atlantic and Southern Oceans are of particular interest because these are regions where deep-water components of global circulation develop. Overall patterns and functioning of modern oceanic circulation is relatively well understood, but significant uncertainty remains about circulation in the geologic past and during different climate regimes. Dr. Romans uses the deep-sea sedimentary record to reconstruct past ocean circulation and its relationship to past climatic and tectonic conditions. He integrates information from a broad range of spatial and temporal scales, from seismic-reflection data that reveals regional sedimentation patterns to high-resolution records based on quantitative grain-size analysis from cores. Dr. Romans will present research from the North Atlantic Ocean (Expedition 342, Newfoundland Drifts) that shows how vast deep-sea “drift” deposits relate to the onset of and changes in ocean circulation in the Eocene through Miocene. In addition to his work on the North Atlantic, Dr. Romans will also present preliminary findings from more recent drilling (January-February 2018) in the Ross Sea (Expedition 374, West Antarctic Ice Sheet History), which aims to study interactions of Southern Ocean circulation and Antarctic ice sheet dynamics during significant climate events of the Miocene and Pliocene.

October 2nd 2020 - Gotta Go: The life and times of the fastest stars in the Milky Way

Speaker: Fraser Evans 

Over the last 15 years, the astronomical community has discovered with increasing frequency stars in our Milky Way galaxy which are travelling at extremely high velocities, up to and exceeding 1000 km/s in the Galactic rest frame. These velocities are high enough such that these stars will eventually escape the Milky Way entirely, leaving us behind as they fly off into intergalactic space. The interest in these objects is two-fold. First, they flag the extreme astrophysical processes capable of accelerating them to such insane speeds, so they can offer insight into the dynamics of stars around supermassive black holes, the physics governing supernova explosions, the nature of dense star clusters, and perhaps even more bizarre phenomena. Second, their ability to travel extreme distances in their lifetimes make them a useful tracer for mapping out the gravitational potential of the Milky Way and our close neighbours. In this talk, I will review the history and current state of fast star research and discuss my own contributions to the field.

Fraser was born and raised in tiny Blind River, Ontario. He did his undergraduate degree at McMaster University, and stuck around to do his MSc studying galaxy evolution under Dr. Laura Parker. After a brief stint as teaching faculty at McMaster, he hopped across the Atlantic to begin his PhD doing theoretical modeling of fast stars at Leiden Observatory in the Netherlands, where he has just entered his third year.

 November 13th 2020 - The MILO Space Science Institute: A New Model for Deep Space Exploration

Speaker: Dr. Jim Bell

The MILO Space Science Institute is a non-profit collaboration among Arizona State University, Lockheed Martin, and GEOShare. MILO was formed in 2018 to test the hypothesis that science-driven deep space robotic missions could also be organized, conducted, and led by consortia of U.S. and international member organizations, rather than only by the world's largest space agencies. Initial MILO activity has been focused on design and development of three inaugural mission concepts that could achieve Decadal-Survey quality science, be conducted relatively quickly as a proof-of-concept of the hypothesis, and be relatively affordable –at a total cost per member up to an order of magnitude or more below the cost that it would cost them to conduct the mission on their own. In this presentation I will describe the MILO concept and “origin story”, the inaugural missions that the Institute is actively pitching to potential members worldwide, and progress to date on specific agreements and plans being formulated with member organizations (including Western University!).

Jim Bell is a professor in the School of Earth & Space Exploration at Arizona State University, where he teaches courses in astronomy, geology, planetary science, and commercial space. He is an active astronomer and planetary scientist who has been involved in solar system exploration using the Hubble Space Telescope, Mars rovers, and orbiters sent to Mars, the Moon, and several asteroids. His research focuses on the use of remote sensing imaging and spectroscopy to assess the geology, composition, and mineralogy of the surfaces of planets, moons, asteroids, and comets. He is also the author of many popular science books related to space exploration, and is the Chief Scientist of the MILO Space Science Institute, a non-profit collaboration between ASU, Lockheed Martin, and Geoshare dedicated to increasing access and opportunities for deep space planetary science missions for member organizations around the world.

December 4th 2020 - Fast radio bursts: What they are, why we care

Speaker: Daniele Michilli

Fast radio bursts are enigmatic radio signals of millisecond duration coming from other galaxies. The source distances imply huge luminosities and prevented us from having a clear idea of their origin. New instruments designed to detect fast radio bursts, such as CHIME/FRB, have made outstanding discoveries in the last months that advanced our understanding of these mysterious sources. Among them, particularly interesting are an exceptionally bright signal from a galactic magnetar and a periodicity in the activity of a repeating fast radio burst source. Independently on their origin, however, fast radio bursts can be used as cosmological probes by measuring the effects caused by free electrons along the line of sight on their signal. Precise localization is needed to pursue this goal and telescopes such as ASKAP are providing groundbreaking results, for example measuring the baryon content of the low-redshift intergalactic medium. Facilities under construction, such as CHIME/Outriggers, promise to revolutionize the field in the upcoming years and provide us with a new tool to study the evolution of the Universe.

Daniele was born in Rome, where he obtained his Master's degree at La Sapienza University. He received his Ph.D. at the University of Amsterdam working on the detection and characterization of pulsars and fast radio bursts. Daniele obtained a Banting Fellowship to continue his research on fast radio bursts at the McGill University in Montreal, where he is currently using the CHIME radio telescope to study these mysterious sources.

January 8th 2021 - Mapping Matter in Strong Gravity: Spectral-Timing of Black Holes and Neutron Stars

Speaker: Dr. Abbie Stevens


One of the best laboratories to study strong-field gravity is the inner 100s of kilometers around black holes and neutron stars in binary systems with low-mass stars like our Sun. The X-ray light curves of these systems show variability on timescales from milliseconds to months — the rapid variability can appear as quasi-periodic oscillations (QPOs), which may be produced by general relativistic effects. My research looks at QPOs from black holes and neutron stars by applying state-of-the-art “spectral-timing” techniques to constrain the physical origin of these signals. In this talk, I will discuss data from NICER, an X-ray telescope attached to the International Space Station. I will also highlight the important role of open-source scientific software in astronomy research.


Dr. Abbie Stevens is an NSF Astronomy & Astrophysics Postdoctoral Fellow at Michigan State University and the University of Michigan. She completed her MSc at the University of Alberta in Canada and her PhD at the University of Amsterdam in the Netherlands. Abbie researches variable emission from accreting black holes and neutron stars in X-ray binaries, to study physical processes in strong gravity. She is also involved in open-source scientific research software, a Steering Committee member for STROBE-X (a proposed NASA mission), an Affiliated Scientist with NICER (a soft X-ray telescope on the International Space Station), and an advocate for mental wellbeing in academia.

 January 15th 2021: Space Exploration and the Search for Entrepreneurial Opportunity

Speaker: Larry Plummer


Entrepreneur Magazine recently proclaimed that a group of ‘rock star’ entrepreneurs were ‘driving the commoditization and monetization of space.’  While this may be true for the technologies we use to get to space (e.g., SpaceX, Blue Origin), there are myriad entrepreneurial opportunities to be found in various activities once we get there.  To this end, this session will focus less on space transportation venturing and more on opportunities in lesser-known areas like space weather forecasting, orbital debris mitigation, planetary resources, and more.


Larry Plummer is an Associate Professor in Entrepreneurship. He earned a Ph.D. in strategy and entrepreneurship at the University of Colorado at Boulder. Before joining Ivey in 2014, Larry was an assistant professor of management and entrepreneurship at the University of Oklahoma's Price College of Business and a past Fellow of the Max Planck Institute for Economics.  His experience as an entrepreneur includes ventures connected to space weather forecasting, precision agriculture, and satellite communication.  Prior to his academic career, Larry directed the “Space Business Initiative” for the American Institute of Aeronautics and Astronautics (AIAA) and, perhaps most proudly, was a volunteer Docent at the Smithsonian’s National Air and Space Museum for nearly a decade.  Larry’s research focuses mainly on regional entrepreneurial dynamics using economic geography frameworks and spatial data.

February 12th 2021: Dragonfly

Speaker: Shannon Mackenzie

smackenzie.pngInsights into the surface of Titan from Cassini VIMS: Why send Dragonfly to the Dunes?”

Over the course of its 13 year mission in the Saturn System, the Cassini spacecraft revealed Titan, Saturn’s largest moon, to be a world both familiar and bizarre. From the lakes and rivers of the poles to the dune strewn deserts, Titan’s geological processes echo those we know here well on the Earth. They operate, however, on the cryogenic chemistries of the outer solar system: liquid methane plays the role of water, water ice the bedrock, and solid organics the sediments. In this talk, I’ll highlight how data from Cassini’s Visual and Infrared Mapping Spectrometer (VIMS) shaped our understanding of this story and how it motivates our return to Titan with the NASA’s latest New Frontiers Mission, Dragonfly

March 5th 2021: Planets Big and Small

Speaker: Dr. Eve Lee

The discovery of thousands of exoplanets revealed a huge diversity in the sizes, masses, and orbital characteristics of planets outside of our solar system. How can we understand the origin of such diversity? We tackle this question by asking what limited the growth of some gas-accreting planets and what stalled their migration, both of which depend sensitively on when the planetary cores assemble and how massive they are. I will describe how the theories of gas accretion and planet-disk interaction can be combined with the measured distributions of radii and orbital periods to reveal the assembly history and masses of exoplanetary cores from sub-Earths to sub-Saturns, and potentially gas giants.

 March 19th 2021: Mining (the Legally Ambiguous) Space

Speaker: Elizabeth Steyn and Valerie Oosterveld

Mining in space is increasingly moving toward reality. Spacefaring nations and entities are interested in mining asteroids and the Moon to support their in-space activities, or to bring rare-earth metals to Earth for the manufacture of electronic devices, electric vehicle batteries and military equipment. Professors Oosterveld and Steyn will discuss the international space law framework, including the Outer Space Treaty, in which such mining will take place and will examine the ambiguities of that framework when applied to the extraction and use of space resources. They will also consider the application of international environmental law applicable to sustainable and responsible mining on Earth in the context of space mining.

 March 26th 2021: From SNOLAB to CERN: A Journey Through Space and Time

Speaker: Ben Davis-Purcell

Abstract: SNOLAB is a massive underground particle physics laboratory located near Sudbury, Ontario. TRIUMF is Canada's National Lab for Nuclear & Particle Physics located in Vancouver, BC. Waterloo's Perimeter Institute is one of the most highly-regarded theoretical physics research facilities in the world. CERN is home to the largest particle physics lab in the world, located near Geneva, Switzerland. What is common about all four of these world-class physics research facilities? I have worked at all of them over the past 10 years, they all have a strong Canadian connection, and most importantly for this talk, they all have (potentially lesser known) astroparticle/astronomy programs! In this talk, I will introduce each of these facilities and highlight components of their space-related programs from a personal perspective.

Bio: Ben completed his Honours BSc in the Physics Co-op program at McMaster University in 2015. He spent many months at SNOLAB, TRIUMF, Jefferson Laboratory, and Perimeter Institute across multiple co-op/research terms working in the interconnected fields of particle/nuclear/astroparticle physics. He then jumped to an entirely different field of physics, completing his MSc in soft condensed matter at McMaster University in 2017.

Dragonfly: A Rotorcraft Lander at Titan

On June 27, 2019, NASA announced its next New Frontiers mission: Dragonfly. This audacious mission will send a rotorcraft to explore Saturn’s largest moon Titan, and evaluate its potential for prebiotic chemistry and (possibly) extraterrestrial life. The Dragonfly mission will also give us a countless high-resolution views of this strangely Earth-like moon, showing us how rivers and sand dunes form on an icy moon at 94 K. In this presentation, I will provide a summary of the history of the Dragonfly mission, its scientific goals, and the next steps forward, from launch in 2026 to landing in 2034

Tagish Lake meteorite fall and investigation: A unique messenger from the early solar system

In the predawn hour of January 18th, 2000, an exceptionally bright fireball was widely seen traveling southeast across Alaska, Yukon and northernmost B.C. The event itself was spectacular and well-recorded, but McCausland_Phil_150x115px.jpegwas surpassed during the subsequent days and months by the recovery of unique meteoritic material from the fall; in all some 10 kg of friable carbonaceous chondrite fragments were recovered from the frozen surface of Tagish Lake. Twenty years on, we can now look back on the event and put this Canadian meteorite in research perspective: The Tagish Lake (hydrous C2) carbonaceous chondrite appears to represent a portion of the solar system that has not previously been sampled, and provides a new window on processes active in the early solar system, from beyond the original “snow line.” Amongst recovered meteorite classes, the Tagish Lake meteorite represents perhaps the most porous, primitive material available, with an exceptionally low mean bulk density of 1.64 ± 0.02 g/cm3 and corresponding porosity of 40%! Chondrules within Tagish Lake appear to be undeformed and representative of their original nebular environment. Tagish Lake is also a host for pre-solar grains and pre-solar organic material. More recently, it is considered to be a likely analogue material for the surfaces of C-type near Earth asteroids Bennu and Ryugu, visited by ongoing sample-return missions OSIRIS-REx and Hayabusa-2, respectively. In its unprecedented features, the pristine nature of the still-frozen fragments that were initially collected, and the large amount of material ultimately recovered, the Tagish Lake meteorite is a premiere scientific event, the subject of essential early solar system research for years to come.

Shadow swarm: the tiny comets of the outer solar system

Up to a trillion kilometre-sized icy planetesimals reside around and beyond Neptune’s orbit, in a region fo the solar system known as the Kuiper Belt. Only a few thousand of the largest ones are known, typically with sizes of a few hundred kilometres or larger. Not even the next generation of space-based, or extremely large ground-based telescopes will be able to directly image the multitude of small icy Kuiper Belt objects. The number, orbital, and size distribution of these planetesimals carry dynamical clues of the early evolution of the solar system. I will overview a new approach to detecting these small and distant planetesimals that relies on the rare and serendipitous occultations of distant stars. Together with my team, we are commissioning the Colibri Telescope Array: a wide-field rapid-imaging observatory dedicated to the detection of stellar occultations by Kuiper Belt objects. I will present our experimental approach to detecting Kuiper Belt objects with Colibri, and will overview the project status and future.

How can Internships Enhance Graduate Learning Experiences?

Pursuing internships during a graduate career can help advance knowledge or technical skills in any given field.  Graduate academic programs are generally research intensive. They demand a substantial time investment in conducting research as well as publishing the results.  In such a setting, the two important questions for graduate students to consider are how to acquire the background knowledge and hands-on skills required for their research, and how to get the results published in time for the degree.  Through internships, graduate students can get a handle on the above aspects of doing academic research work. I will share my experience while working as an astronomy graduate intern at the Gemini North Observatory (Hilo, Hawai‘i) in the summer of 2019 through the New Technologies for Canadian Observatories (NTCO-CREATE) program.

The 2020 Long-Range Plan for Canadian Astronomy & Astrophysics

A large fraction of research in observational astrophysics relies on shared facilities too large to be operated by any one research group or university. Planning for and funding these facilities requires coordination within the research community. Organized by the Canadian Astronomical Society, LRP2020 is the third in the series of Canadian Long Range Plans for astronomy and astrophysics. LRP2020 is reviewing the field of astronomy and astrophysics, along with associated education, training, and outreach programs, and will produce a list of recommended priorities for the next decade. In this talk I’ll describe the current state of the LRP process, especially as it relates to space astronomy. I’ll describe some future proposed missions and how the LRP interacts with other research fields, the Canadian Space Agency and Canadian industry.

Training and Engaging the Next Generation of Space Scientists and Engineers through the Space Explorers Program

The Western Space educational outreach program strives to engage youth to explore the universe and aims to empower children with the basic knowledge and workings of the many branches of planetary science and space exploration. The Space Explorers program promotes experiential learning and since its launch, has engaged more than 600 students through hands-on activities. To assess the potential of the Space Explorers Program to engage youth, camp participants are invited to complete a survey at the conclusion of the program. Survey statements gauge campers' experiences, as well as their interest in the field of space science and technology, thus providing insights into the impact of the program. The survey also allows for the evaluation of programming, camp activities, and facilitators. Based on preliminary findings, the program is certainly on its way to achieving the goal of engaging and training the next generation of scientists and engineers, while exposing them to various aspects of planetary science, space and space exploration. We intend to leverage campers' experiences and recommendations to continue developing robust programs as we move into the next phase of science and technology themed educational outreach initiative.

Direct measurements of dust-drag fluid instability in connection with protoplanetary disk evolution

How planetary precursors (planetesimals) from out of the dust grains present in gaseous protoplanetary disks remains an open question. While grain adhesion forces bind solids at small scales (micrometers-decimeters) and gravity on large scales (kilometers), bridging these extremes across growth barriers in the meter size range requires an additional solid-concentration mechanism, often assumed to derive from the two-way drag coupling between the gas and solid phases, which results in a 'streaming instability'. I present the findings from ground-based two-phase flow experiments which represent the first and only demonstration of particle concentration via the theorized flow instability. The experiments support the growing consensus that dust-drag instability should occur universally, and derives principally from the differential motion of dust and gas in a mass-loaded fluid. While these results do not prove that planetesimals form by aero-gravitational instabilities, they strongly suggest that streaming-instability-driven turbulence is inevitable, provided that the control parameters can reach critical values. This parameter regime has not otherwise been reached in laboratory studies and neither is it directly addressed by existing theory of particle suspension dynamics. I will discuss the continuation of this research, meant to connect classical approaches to studying granular two-phase flow with the study of astrophysical fluids and planetesimal formation and evolution.

WesternU misson operations and training with the HiRISE imager on the Mars Reconnaissance Orbiter: Results from Imaging cycles 339 & 340

Since late 2014, CSA-funded adjunct research professor Livio Tornabene, has led WesternU-based science operations and training for the most powerful and high-resolution imager to photograph Mars: HiRISE. Starting on Oct. 8th of this year, two teams led by himself and PDF Eric Pilles and four trainees (Vidhya Ganesh Rangarajan, Chimira Anders, Leah Sacks and Will Yingling) helped plan 213 new images of Mars over a 4-week period. HiRISE’s 339rd imaging campaign (led by Tornabene) executed on Saturday, Oct. 26th and continued to Saturday, Nov. 9th when it handed off to the 340th imaging campaign (led by Pilles), which continued to Saturday, Nov. 23rd as Mars continued into Northern Summer/Southern Winter. Here they present together their latest exploits, and what they experienced while planning two back-to-back two-week sets of high-resolution images of the surface of Mars from WesternU’s Mission Control facility. Come hear all about it and to see some of their favorite images!

An Instrumented Rover Wheel

Barefoot Rover is a research project at NASA-JPL with the intention of assessing the feasibility of a tactile-sensing rover wheel. In doing so, rover safety may be enhanced through in-situ terrain data, and the scientific community can benefit from knowledge of terramechanics parameters. The planetary surface community is also interested in rock and surface pattern detection. My focus for this work is the terramechanic aspect, which is the study of wheel or tracked vehicle interaction with the terrain, where the terrain's properties are of utmost interest. An additional area of research work is applying machine learning methods to the data for in-situ analysis. Detecting different terrains, such as loose sand or duricrust, will help rover drivers avoid unsafe terrain or flag areas for further study. Duricrust is loose sand covered by a layer of hard, or high cohesive strength, soil. MER Spirit broke through a layer of duricrust on Mars and became immobilized. The implementation of a tactile-sensing wheel on future rovers will mitigate driving risks and enhance rover autonomous driving capabilities.

Western’s eyes on the JWST skies

Today, the world is eagerly awaiting the launch of the James Webb Space Telescope (JWST). Hailed as the bigger and more sensitive successor to the Hubble Space Telescope (HST), JWST will similarly inspire the general public and have researchers develop the most innovative approaches to process and analyze observations of unprecedented quality to study the Universe near and far. Given these expectations, the entire world will be watching closely when the first science observations with JWST are presented to the public, and those may well have a Canadian stamp on them. In this talk, I'll give a general description of JWST and its capabilities, and I will highlight how Western is involved in the first science observations to be made by JWS.

Interstellar asteroids and comets: what are they and where do they come from?

In 2017, the first asteroid to enter our Solar System from interstellar space was discovered by Rob Weryk (who did his PhD here at Western) at the PanSTARRS telescope. The asteroid is now called 'Oumuamua, a Hawaiian term which signifies 'Messenger from Afar'. Now in 2019 a second visitor, comet Borisov (named after its discoverer) has also appeared. 'Oumuamua was rocky (unexpected), relatively slow (unexpected) and small (expected); while Borisov is icy (expected), fast (expected) and large (unexpected). I'll briefly summarize what we know about these puzzling visitors, and outline the efforts being made at Western to back-track them to their points of origin, somewhere within our Milky Way galaxy.

The distribution of organic material in Martian-analogue volcanic rocks, as determined with ultraviolet laser-induced fluorescence spectroscopy

The Biologic Analog Science Associated with Lava Terrains (BASALT) research project (Lim et al., 2019) has been developed to test exploration capabilities and return samples from two Mars-analogue volcanic environments. We used an ultraviolet laser-induced fluorescence (LIF) spectroscopy instrument to detect and characterize the distribution of potential organic biosignatures in samples returned from two BASALT mission deployments and correlate the fluorescence results with a variety of sample properties. These samples represent a range of alteration conditions found in the volcanic environments of Hawai’i Volcanoes National Park, HI, USA and Craters of the Moon National Monument, ID, USA. Samples were also analyzed using scanning electron microscopy with electron-dispersive x-ray spectroscopy (SEM-EDS) to characterize the mineralogy present at fluorescent points-of-interest and confirm the presence of carbon-bearing material. Finally, He-gas pycnometry and micro-computerized tomography were used to determine the porosity of the samples, which could be compared to the results from LIF and SEM-EDS measurements. Some minerals deposited in the sample vesicles through fumarolic activity were found to be highly fluorescent, with time-resolved fluorescence spectra suggesting the presence of organic material associated with these mineral deposits. Overall, samples collected proximate to active or relict meteoric fumaroles from Hawai’i were shown to contain materials with strong evidence for organic deposits, compared to little evidence in samples collected from Idaho.


High Altitude Balloon team October 25 2019 – UCC 54A 12:30 – 1:30pm 

High Altitude Balloon Initiative

The High Altitude Balloon Initiative began in January 2018 and has launched two separate payloads since its conception. In May 2018 the team launched a ~2 kg payload carrying a suite of various atmospheric sensors to study the environment of the upper atmosphere. While the initial assembly of the team and the launch itself was successful, the loss of GPS data at the apex of the flight complicated the recovery of the payload. The payload was recovered on May 29, 2019 near Grand Valley, Ontario after being discovered in a field. To conduct a second launch in 2019, the High Altitude Balloon (HAB) team partnered with the Students for the Exploration and Development of Space (SEDS)-Canada and the Canadian Space Agency (CSA) to sample microbial aerosols via stratospheric balloon as part of the CSA’s STRATOS program. The ~800, 000 cubic meter balloon travelled to an altitude of 37 km and Westernu HAB’s payload, housed on the gondola, was controlled remotely from the ground during the flight. The gondola was shared by five other experiments running simultaneously. SEDS-Canada had arranged to reserve two spaces on the CSA’s gondola, one of which had been granted to the Westernu HAB team for this year’s launch. The experiment successfully sampled microbial aerosols at four different points during the flight and was returned via helicopter to have the samples preserved as soon as possible. Currently the samples are being analyzed to determine whether any variations exist as a function of altitude

Volcanic Analogue for the Exploration of Mars

In July 2019, Gavin Tolometti traveled to the 2014-15 Holuhraun lava field in Iceland to study its diverse lava flow morphology's and compare them to radar and high-resolution (cm-scale) topographic remote sensing data. Remote sensing data is relied upon when studying the morphology of surface features, including lava flows, on other planetary bodies such as Mars. It is important to understand how to interpret the data because results and interpretations are dependent on the wavelength scale and resolution. Gavin will discuss why it is important to understand and compare different remote sensing datasets to study lava flow morphology and summarize the research that has been completed and currently ongoing at the 2014-15 Holuhraun lava field.

The Holuhraun lava field is situated in the Bárðarbunga-Veiðivötn, one of Iceland’s largest volcanic systems, and is marked as the largest effusive basaltic eruption since the Laki eruption in 1783-84. On the 29th of August 2014, a small 600 m long fissure opened on the floodplain and for four hours basaltic lava erupted onto the surface. Extension of the fissure to 1.8 km occurred after twenty-four hours of inactivity. From the 31st of August to the 27th February 2015, the effusive basaltic eruption occurred and had a maximum discharge rate of ≥350 m3/s, average flux of ~90 m3/s, a total area cover of ~85.4 km2 and an estimated bulk volume of 1.44 km3. The lava field stands as a strong Martian analogue site because of its pristine condition, hosting lava flow morphology's analogous to Martian lava flows, proximity to glaciers and diverting an active hydrology system, which has implications for astrobiology.

Exploring Other Worlds By Exploring Our Own

The world of space exploration is rapidly evolving. More than ever before, the international scientific community is attempting to answer fundamental questions on the origins of life and of the Solar System, by exploring other planetary bodies. There are currently more active robotic space missions than at any other time in history. It is clear that humans will return to the Moon, possibly within the next 5 years. The Moon is the only planetary body, besides the Earth, to have been explored by humans. Currently, the only way we can "explore" Mars and other planetary bodies is via images and chemical data sent back from unmanned orbiting spacecraft and rovers, and through the study of meteorites. Interpretations of other planetary bodies must, however, begin by using the Earth as a reference. This introduces the concept of terrestrial analogues, which are places on Earth that approximate the geological, environmental and/or putative biological conditions on Mars and other planetary bodies, either at the present-day or sometime in the past. From impact craters to hot springs to polar deserts, Canada possesses a wide variety of analogue sites that serve to inform scientific interpretations from space missions through the field of comparative planetology.

In addition to enabling comparative planetology studies, terrestrial analogues allow for the development and testing of technologies, psychological studies for long duration space missions, software and operations architectures, the training of personnel for future missions, and opportunities to engage and educate children and the general public. Analogue missions represent integrated, interdisciplinary field campaigns conducted in terrestrial analogue environments and provide a critical pathway in preparing to return to the Moon.

Space weather phenomena is a complex area of research and many different variables and signatures are used to identify the occurrence of solar storms and Interplanetary Coronal Mass Ejections (ICMEs), with inconsistencies between databases and solar storm catalogues. The identification of space weather events is important from a satellite operation point of view, as strong geomagnetic storms can cause orbit perturbations to satellites in low-earth orbit. The Disturbance Storm-Time (Dst) and the Planetary K-index (Kp) are common indices used to identify the occurrence of geomagnetic storms caused by ICMEs, among several other signatures that are not consistent with every storm. Moreover, specific instrumentation is needed for solar storm and space weather phenomena, which can be costly and infeasibly difficult for small and nano-satellite applications. In our work, we demonstrate the capability of a new signature for identification and characterization of Interplanetary Coronal Mass Ejections, through the use of satellite accelerometer data from the GRACE satellite, and machine learning techniques. Utilizing pre-existing satellite instrumentation, we propose the use of accelerometers for future space weather monitoring applications. Four binary classification algorithms have been explored: Random Forest, Support Vector Machine, Extremely Randomized Trees, and Logistic Regression. It is proposed that a binary classification model can differentiate between a solar storm caused by an ICME versus a period of quiet geomagnetic activity, using only the accelerometer data of a satellite.
