MethaneSAT, the Environmental Defense Fund (EDF) methane-tracking satellite backed by the Bezos Earth Fund, is lost in space. Its ground team lost contact with the spacecraft on June 20 but tried to reestablish a connection until it learned in the morning of July 1 that MethaneSAT had lost power altogether. The team believes that the satellite is likely not recoverable. MethaneSAT collected data on methane emissions that have previously been untrackable in an effort to combat climate change. Methane is the second largest contributor to global warming after carbon dioxide, with agriculture, fossil fuels and waste decomposition being the largest sources.
In its announcement, the MethaneSAT team said that the spacecraft’s observations have given us critical insight about the distribution and volume of methane being released from oil and gas production regions. Thanks to the satellite, scientists have also developed the capability to “interpret the measurements from space and translate them into volumes of methane released.” That knowledge can be used in future missions.
EDF developed the mission, which launched in March 2024, to hold the countries who previously pledged to slash their methane emissions accountable. It created Google Cloud-powered algorithms to calculate and monitor methane emitted in certain regions with held from Harvard and Smithsonian scientists. While the satellite itself is gone, the MethaneSAT team vowed to work with other scientists to leverage the algorithms and software developed for the project. The team will also continue processing the data the satellite had sent back.
