In an epochal event on November 11, the SpaceX Transporter 9 rideshare mission made headlines with the launch of Vanguard, the world’s first satellite designed to pinpoint carbon emissions from space. This groundbreaking development, spearheaded by Montreal-based firm GHGSat, marks a significant leap in our ability to monitor and understand environmental impacts on a global scale.
Overview of the Vanguard Satellite
Vanguard, an innovative satellite, has the unique capability to detect emissions from individual industrial sources such as coal and gas-fired power plants, large oil refineries, and steel plants. Orbiting Earth at an altitude of 300 miles, Vanguard will image each spot on the planet every two weeks, providing invaluable data for environmental monitoring and research.
Technological Innovations in Emission Detection
The satellite employs an advanced Wide Angle Fabry–Pérot Interferometer, a novel instrument developed by GHGSat. This technology was initially fine-tuned for methane emission monitoring and has now been adapted to spot and quantify carbon dioxide emissions.
“We are looking for very specific absorption lines,” GHGSat’s President Stephane Germain explained…
“The amount of the gas in the atmosphere is then proportional to the amount of absorption of light at those specific wavelengths. So, we can quantify the concentration of carbon dioxide in every pixel of our field of view.”
SpaceX’s Role and Launch Details
The collaboration with SpaceX for the launch signifies the growing synergy between space exploration companies and environmental initiatives. Vanguard’s launch aboard a SpaceX rocket showcases the increasing role of private space firms in supporting crucial environmental monitoring missions.
Impact on Environmental Monitoring
Unlike previous satellites that struggled to detect individual human-made carbon emissions sources, Vanguard’s technology represents a major advancement. It builds upon the achievements of NASA’s Orbiting Carbon Observatory 2 (OCO-2), which earlier this year made strides in measuring fluctuations in emissions from a major coal-fired power plant.
Future Prospects and Challenges
Despite these advancements, challenges remain. Earth-observation consultant Aravind Ravichandran notes:
“It is relatively less disruptive compared to methane…With carbon dioxide, it is a case of verification of the major emissions.”
In Summary
The launch of Vanguard by SpaceX is more than just another successful mission; it’s a testament to human ingenuity and our commitment to preserving the environment.
