Earth scientists hope a new priority setting effort will help them make the most of NASA9s limited budget for satellite missions that watch over the planet. The so-called decadal survey, issued in January by the National Academies of Sciences, Engineering, and Medicine, laid out the community9s consensus wish list, ranging from cloud monitoring to multiwavelength imaging—and recommends a strong dose of competition to keep costs down. The report prioritizes five observations for launch, including hyperspectral imaging, clouds, atmospheric particles, and missions to chart gravity variations and tiny crustal movements. It also advocates creating a new line of $350 million missions targeting seven observations, with competitions to choose three for flight in the next 10 years.

地球科学家列出了太空任务的首要任务

地球科学家希望一项新的优先事项设置工作将帮助他们充分利用 NASA9 的有限预算，用于监视地球的卫星任务。美国国家科学院、工程院和医学院于 1 月发布的所谓的十年调查列出了社区的共识愿望清单，范围从云监测到多波长成像，并建议进行强有力的竞争以降低成本。该报告优先考虑发射的五项观测，包括高光谱成像、云、大气粒子，以及绘制重力变化和微小地壳运动的任务。它还主张创建一条新的、价值 3.5 亿美元的任务线，目标是 7 次观测，​​并在未来 10 年内竞争选择三个进行飞行。
