  "account": "NASA's Nancy Grace Roman Space Telescope has exceeded expectations with its fuel savings, potentially doubling the mission's operational lifetime. The first mid-course correction, executed with over 99% accuracy, consumed only 40 pounds of fuel instead of the 441 pounds initially budgeted. This success, coupled with extra fuel loaded at launch due to the telescope's lighter-than-planned weight, adds four more years to the mission's life. The second mid-course correction and orbital insertion are expected to further conserve fuel, potentially adding another four years. The telescope was designed for a 10-year mission, but these fuel savings could enable an additional 22 years of science operations.",
  "summary": "The results are in: NASA’s Nancy Grace Roman Space Telescope’s very accurate first mid-course correction, along with other fuel savings, are expected to more than double the mission’s potential operational lifetime. “As a result of exquisite planning by our orbital dynamics team, brilliant execution by the operations team, and a precise launch from SpaceX, Roman […] The post Fuel Savings Double…",
