(Business Wire/AP pic)WELLINGTON: A satellite backed by billionaire Amazon founder Jeff Bezos has been lost in space while carrying out an important climate change mission, New Zealand officials said today.Designed to measure greenhouse gas emissions with 鈥渦nprecedented resolution鈥, the MethaneSAT space probe was also funded by Wellington and the US-based environmental defence fund.Plagued with technical problems, the satellite recently stopped responding to its Earth-bound controllers.鈥淐learly, this is a disappointing development,鈥 said Andrew Johnson, a senior official at the New Zealand Space Agency.鈥淎s those who work in the space sector know, space is inherently challenging, and every attempt 鈥 successful or not 鈥 pushes the boundaries of what we know and what we鈥檙e capable of.鈥漈he environmental defence fund, which led the project, said it was 鈥渄ifficult news鈥 but would not be the end of its methane-tracking efforts.MethaneSAT was designed to measure emissions of the potent greenhouse gas, which fuels climate change by trapping heat in the planet鈥檚 atmosphere.It has proven notoriously difficult to get accurate estimates of the methane emissions belched out by oil and gas projects around the globe.鈥淚t was one of the most advanced methane tracking satellites in space, measuring methane emissions in oil and gas producing regions across the world,鈥 the MethaneSAT team said.鈥楻emarkable鈥橮roject lead Steven Hamburg said initial data gleaned by the satellite was 鈥渞emarkable鈥.鈥淩ecent measurements in the Permian Basin of Texas and New Mexico revealed emissions three to five times higher than estimated by the US environmental protection agency, while emissions observed in the South Caspian region are over 10 times higher than reported,鈥 Hamburg wrote on LinkedIn.MethaneSAT was launched into space in March 2024 on the back of a SpaceX rocket fired from California鈥淭he engineering team is conducting a thorough investigation into the loss of communication,鈥 MethaneSAT said.鈥淭his is expected to take time. We will share what we learn.鈥滵espite its shorter-than-expected lifespan, MethaneSAT hailed the mission as a 鈥渞emarkable success in terms of scientific and technological accomplishment鈥.Amazon founder Bezos pumped more than US$100 million into the project through his philanthropic Earth Fund.The satellite eventually succumbed after overcoming a string of technical glitches.It repeatedly entered a sleep, or stand-by, mode without prompting 鈥 forcing engineers to perform a lengthy reset each time.One of its three thrusters also failed.
