    Presenter: Eric Choi, Director of Business Development GHGSat Inc.

    Presentation

    Methane is a potent greenhouse gas with 80 times the global warming potential of carbon dioxide over the first 20 years after release. A quarter of today’s global temperature increases are caused by anthropogenic methane. Reducing methane emissions 45% over the next five years would have the same 20 year climate benefit as closing 1,300 coal-fired power plants.

    Canadian space technology is addressing the growing need for global transparency in methane emissions. A number of past (e.g. SCIAMACHY), current (e.g. Sentinel-5P/TROPOMI) and future (e.g. GeoCarb) space agency missions provide methane data on regional and global scales. An exciting development is the emergence in Canada and abroad of commercial remote sensing companies like GHGSat that are pushing the boundaries with innovative and complementary Earth observation capabilities that would otherwise not be possible with either a space agency or private sector mission alone.

    GHGSat’s satellites enable the quantification of facility-level methane emissions and provide data and analytics for stakeholders in the energy, resource, power generation, agricultural, waste management, and sustainability sectors to make informed environmental decisions. There are currently three GHGSat satellites in orbit, with the next three satellites scheduled for launch this summer and three more satellites now under construction towards the goal of a ten satellite constellation by the end of 2023. No other government or commercial satellite mission is currently capable of quantifying methane emissions from point sources as small as individual oil and gas wells.

    This presentation will include a short history of satellite-based methane monitoring, a summary of GHGSat’s satellites and their capabilities, a description of how GHGSat’s high-resolution satellites work synergistically with regional-scale data from space agency missions, and conclude with some examples of recent observations from GHGSat’s satellites.

    CEOS System of Systems

    Presenter: Ivan Petiteville | Committee on Earth Observation Satellites

    Special Guest Speaker: Éric Laliberté | Director General, Space Utilization,

    Canadian Space AgecyThe Committee on Earth Observation Satellites (CEOS) was established in 1984 in response to a recommendation from a Panel of Experts on Remote Sensing from Space and set up under the aegis of the G7 Economic Summit of Industrial Nations Working Group on Growth, Technology, and Employment. This Panel recognized the multidisciplinary nature of space-based Earth observations and the value of coordinating international Earth observation efforts to benefit society.

    Accordingly, the original function of CEOS was to coordinate and harmonize Earth observations to make it easier for the user community to access and use data. CEOS initially focused on interoperability, common data formats, the inter-calibration of instruments, and common validation and inter-comparison of products. However, over time, the circumstances surrounding the collection and use of space-based Earth observations have changed.

    This presentation provides an overview of CEOS and shows some examples of the numerous CEOS achievements, thanks to the scientific and technological cooperation of the major space agencies in the world, and the interoperability of their assets.

    Synopsis

    With the onset of the COVID-19 pandemic, airlines worldwide increased the frequency of aircraft disinfection manyfold. At the core of each type of disinfection, a chemical-based application is used to help reduce pathogenic concentrations on surfaces. While effective, chemical disinfection has many disadvantages.

    UVC light-based disinfection has strong scientific backing demonstrating efficacy against numerous pathogens studied in the past few decades, including recent studies that show its efficacy against SARS-CoV-2. With feedback from our operator community worldwide on the need for a less intrusive disinfection methodology, De Havilland Canada supported aero hygenx in the design, development, and testing of RAY – an autonomous UVC light-based disinfection robot for use on aircraft. The goal was to create a sustainable, consistent, and chemical-free disinfection solution, not just for the current coronavirus threat but also for variants and novel pathogens that may arise in the future. De Havilland Canada has also completed an extensive material compatibility study to determine any effects (particularly those that might affect airworthiness) of repeated UVC disinfection on materials found on the Dash 8 aircraft.

    De Havilland Canada and aero hygenx developed the solution to be applicable not just on the Dash 8 aircraft but for the aviation industry in general. RAY is currently being introduced in-service and airlines are implementing UVC light-based disinfection on the Dash 8 and other aircraft. This presentation will share a journey of how UVC disinfection went from a small vision to a reality through RAY in a matter of months.

    Presenter

    This is a recently revised presentation of the Daniel and Florence Guggenheim Memorial Lecture on Civil Propulsion; The Last 50 Years given in 2002.

    This presentation covers propulsion development in the civil field over the last seven decades. It is notable that aircraft have displaced ships and railways for long distance passenger travel, and this could not have been achieved without the continuous development of the aircraft gas turbine.

    The talk traces propulsion developments from the end of the piston era through the early turboprops and turbojets to the high bypass ratio turbofans to the latest advances in geared turbofan technology.

    While the aircraft gas turbine has attained extremely high levels of safety, reliability and efficiency, the aviation sector is facing existential challenges today that will require resilience and innovation to solve.
