Research Themes

Though CPSX incorporates various groups and entities including the departments of Electrical and Computer Engineering, Mechanical and Materials Engineering, Civil and Environmental Engineering, Physics and Astronomy, Earth Sciences, Biology, and Geography but they are connected by five interdisciplinary core Research Themes:

Earth Observation, Monitoring, and Protection

 Blue Marble photo of Earth taken during the Apollo 11 mission (NASA).

One of the most iconic images ever taken is the famous "Blue Marble" photograph taken on December 7th 1972, as the Apollo 17 crew left Earth’s orbit for the Moon. This image was the first to capture a full view of the Earth and inspired the whole concept of environmental protection in the 1970s. It provides a constant reminder of the inexorable links between Space Exploration and Earth Observation, Monitoring, and Protection.

Research conducted in the Earth Observation, Monitoring, and Protection theme takes a multifaceted and interdisciplinary approach to using satellites and ground-based systems to study the atmospheric divide between the Earth’s atmosphere and “space”. These same systems are also used to monitor hazards associated with space debris and the impact of extraterrestrial objects on Earth. Data from Earth-observation satellites are used to monitor and protect our environment, map remote regions of the world (e.g., Arctic Canada), and to explore for, and manage existing, natural resources in a sustainable way. This theme contains three main subthemes:

  • Remote sensing and remote predictive mapping – using satellites to produce remote predictive maps of the Arctic and other regions of the world, to search for natural resources, and for environmental monitoring;
  • Atmospheric studies – studying Earth’s atmosphere from the ground to altitudes of ~110 km, monitoring atmospheric change;
  • Space hazards – studying and monitoring natural hazards in the form of meteors, to the increasing problem of space debris.

Exploration Technologies

ROC-6 Rover exploring Sudbury Lunar Analogue Site

It is widely recognized that Space is an innovation driver and that participation in international space projects demonstrates Canada’s position as a sophisticated research and innovation leader, with a global advantage in several niche technology areas, including robotics. At the same time, there are increasing commonalities in the techniques and technologies being used in the exploration of Space to and the exploration of remote and/or extreme locations on Earth, such as northern regions of Canada and deep underground mines. These technological advances involve the increasing use of robotics, autonomous data capture, and real-time analysis. Research conducted in the Exploration Technologies theme focuses on the following subthemes: 

  • instrumentation – designing instrumentation for the real-time analysis of samples; CPSX’s partnership between scientists and engineers allows us to solve science-driven engineering design problems to develop instrument designs that are optimized for scientific return
  • Robotics and Telerobotics – designing robotic and mechatronic systems that can be used to collect, analyse and curate samples from both Earth and space. This work includes teleoperated systems for mining and sample extraction, rover design and control and automated processing of scientific data.
  • Power systems – space and other remote systems must operate independent of infrastructure. This research theme focuses on power systems built around renewable resources such as nuclear, wind and solar power and on the design of microgrids for localized power distribution and control 
  • Communications and data science – scientific return from exploration missions, both in space and in remote regions of the Earth, depends on the ability to collect, transmit, store and analyze large data sets. Hyperspectral camera scans can easily generate terabytes of information in a matter of hours. At the same time, exploration missions have limited power and communication bandwidth available. As a result, specialized data management solutions are required.

Planetary Processes

The 2015 expedition to Tunnunik crater - exploring other wolrds by exploring Earth.

The surface and atmosphere of Solar System objects are shaped by numerous processes, both endogenous (e.g., volcanism) and exogenous (e.g., meteorite impact). The discovery of planets outside our Solar System (exoplanets) extends this quest to understand planetary processes to even more distant worlds. Research in the Planetary Processes theme seeks to understand the origin and dynamics of planetary systems and the processes that subsequently shape their interior, surface, and atmospheres. Knowledge of these processes provides important constraints for understanding the origin of life on Earth and the prospect of finding life elsewhere in the Universe. The main subthemes are: 

  • Planetary Surface Processes – studying the features visible on planetary bodies and trying to understand the underlying physical processes which produce them;
  • Planetary Atmospheres – examining the thin veneer of gases that surround most planet- sized bodies and interpreting gas dynamics, thermodynamics and chemistry;
  • Planetary Dynamics – understanding the interaction of planets and small bodies dynamically and observational characterization of planetary objects within and outside our Solar System;
  • Planetary Interiors – inferring the internal structure of planetary bodies and unravelling their formation histories and subsequent evolution;
  • Exoplanets – searching for extrasolar planets and investigating the formation and diversity of planetary systems, the place that our own solar system occupies in this broader picture, and the habitability of extrasolar planets;
  • Planet Formation – conducting observational and theoretical investigations on the environments and processes that lead to the formation of planetary systems, and studying their evolution 
  • Planetary Habitability – Understanding the processes and conditions that result in habitability, the search and recognition of habitable environments within and beyond our Solar System.

Planetary Materials

Research in the Planetary Materials theme focuses on the analysis of planetary materials (meteorites, Apollo samples, etc.) and materials from planetary analogue environments on Earth (e.g., impact craters, hot and cold springs) in the laboratory. This is critical for developing a more detailed and quantitative understanding of Solar System history and chronology. Materials research forms a cornerstone of astrobiology through the study of extremophiles and the identification of biosignatures that informs planetary exploring missions looking for signs of past or present life elsewhere. The main themes are: 

  • Cosmochemistry – probing planetary materials in the laboratory as a means to develop a more detailed, quantitative understanding of solar system history and chronology; 
  • Meteorite impacts – studying the products of meteorite impact events on the Earth, asteroids, Moon and Mars;
  • Natural resources – exploring for, and studying, natural resources on the Earth and investigating the potential for resource extraction on the Moon and asteroids; 
  • Biosignatures and Extremophiles – understanding the limits of life on Earth through the study of extremophiles and investigating how evidence for life is preserved as biosignatures.

Galactic and Stellar Processes

Artist concept that depicts the tiny planetary system of KOI-961 (NASA).

The properties of the Earth and indeed of all planets are intimately tied to those of their parent stars, and their broader neighbourhood in space. Our own Sun is one of billions of stars in the Milky Way, a galaxy that provides the wider context in which planets form and evolve. A complete understanding of planetary processes is thus dependent upon a clear knowledge of Galactic and Stellar Processes, the fifth research theme of CPSX.

  • Star Formation and birth – stars continue to be born within our galaxy and it is only during the creation of stars that planets can also form
  • Extragalactic star formation– the formation of stars in other galaxies provides insights into the same processes closer to home.
  • Interstellar medium– the clouds of gas between the stars, the interstellar medium, is the birth place of stars and planetary systems.
  • Massive stars– stars with masses much larger than our Sun explode as 'supernovae' at the end of their lives, releasing the heavy elements needed for the formation of the next generation of planets, and completing the ecological cycle of the galaxy.
