MethaneSAT is an innovative satellite launched on a SpaceX Falcon 9 rocket, designed specially to track and measure methane emissions around the globe. This satellite is a vital tool in the fight against climate change, focusing on emissions from the oil and gas sector.

Purpose of MethaneSAT

The primary purpose of MethaneSAT is to monitor methane emissions. By providing unique data on the sources and trends of these emissions, it can help identify where changes are happening over time. This information is vital for policymakers, businesses, and environmental organizations to develop effective strategies to reduce methane emissions.

Key Features of MethaneSAT

Developers and Partners

MethaneSAT was created by the Environmental Defense Fund (EDF) in collaboration with:

  • Harvard University
  • The Smithsonian Astrophysical Observatory
  • The New Zealand Space Agency
Orbiting the Earth

The satellite will orbit the Earth 15 times a day, collecting data that will be made publicly available in nearly real-time. This frequent data collection ensures updated information on methane emissions.

Advanced Technology

MethaneSAT is equipped with cutting-edge technology, including:

  • A high-resolution infrared sensor
  • A spectrometer capable of detecting methane concentrations as low as three parts per billion

This advanced technology enables MethaneSAT to identify both large and small methane emitters effectively.

Understanding Methane

Methane is a colorless, odorless, and flammable gas, making it the primary component of natural gas. However, it is also a potent greenhouse gas (GHG) that significantly impacts the Earth’s climate system. Reducing methane emissions is crucial for slowing down global warming and protecting our environment.
