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.

An $88 million satellite backed by billionaire Jeff Bezos is lost in space. MethaneSAT, designed to sniff out sources of methane emissions across the globe, only survived about 15 months in Earth’s orbit before meeting its untimely end.

The spacecraft, MethaneSAT, was just a year into its mission to provide a clearer picture of planet-warming emissions from oil and gas sites.
