A satellite tv for pc referred to as MethaneSAT, anticipated to remodel our view of methane emissions, has misplaced energy lower than a yr and a half after it was launched.
MethaneSAT is “possible not recoverable”, in line with a assertion from the Environmental Protection Fund (EDF), the non-profit organisation that launched and operated the satellite tv for pc. Its loss is a significant blow to efforts to trace and cease methane emissions, that are liable for a few third of the human-caused rise in world temperature thus far.
When MethaneSAT launched in March 2024, it joined a rising constellation of satellites designed to detect invisible methane emissions from key sources like oil and gasoline wells, livestock, landfills and wetlands. Whereas some satellites zoomed in on particular person sources and others might look throughout entire areas, MethaneSAT was uniquely suited to detect methane on the center scale, making it supreme for recognizing emissions from oil and gasoline manufacturing.
This view was meant to estimate methane emissions from areas recognized for fossil gas manufacturing, just like the Permian Basin within the south-western US. It might additionally assist efforts to establish and cap the most important sources of the potent greenhouse gasoline.
“It’s a major loss,” says Jason McKeever at GHGSat, a Canadian firm that had deliberate to make use of MethaneSAT’s knowledge to make selections about the place to level its personal satellites. “MethaneSAT was uniquely positioned. It was in a particular in-between zone.”
The satellite tv for pc, which value practically $100 million to construct and launch, began accumulating knowledge in June of final yr and launched its first detections of methane from oil and gasoline basins in November 2024. Researchers have been engaged on methods to automate knowledge processing so the satellite tv for pc, which nonetheless orbits the planet 15 instances per day, might ship info on emissions in close to actual time.
“We had simply began a cadence of releasing knowledge each two weeks,” says Jon Coifman on the Environmental Protection Fund. “The satellite tv for pc had been producing wonderful info.”
In keeping with the EDF’s assertion, mission operations misplaced contact with the satellite tv for pc on 20 June. “After pursuing all choices to revive communications, we discovered this morning that the satellite tv for pc has misplaced energy,” it mentioned.
The MethaneSAT workforce continues to be investigating precisely what went improper. It should proceed to share the info the satellite tv for pc was in a position to gather earlier than dropping energy, in addition to the algorithms developed to analyse it.
“We’re taking a look at all types of choices,” says Coifman. Launching one other satellite tv for pc isn’t off the desk, he says.
