以新的方式探索气候数据

Local students take in the sights—and data—at an Earth Information Center student engagement event, Friday, June 23, 2023, at NASA Headquarters in Washington. The Earth Information Center is a new immersive experience that combines live data sets with innovative data visualization and storytelling to show visitors how our planet is changing. The center gives...

TROPICS准备跟踪风暴

A Rocket Lab Electron rocket stands on Pad B, Launch Complex 1, in Māhia, New Zealand, just ahead of a successful launch on Friday, May 26, with NASA’s Time-Resolved Observations of Precipitation structure and storm Intensity with a Constellation of Smallsats (TROPICS) CubeSats payload. Now that the final pair of CubeSats are in orbit, TROPICS will study the...

参观NISAR

Officials from NASA, the Indian Space Research Organisation (ISRO), and the Indian Embassy visit a clean room at NASA’s Jet Propulsion Laboratory on Feb. 3, 2023, to view the scientific instrument payload for the NASA-ISRO Synthetic Aperture Radar (NISAR) mission. The NISAR mission—a joint effort between NASA and ISRO—will measure changes to Earth&#821...

升空!JPSS-2和LOFTID成功发射

The Moon makes a stunning backdrop for the successful launch of the third in a series of polar-orbiting weather satellites for the National Oceanic and Atmospheric Administration (NOAA) and our Low-Earth Orbit Flight Test of an Inflatable Decelerator (LOFTID) on Nov. 10 at 4:49 a.m. EST from Vandenberg Space Force Base in California.

NASA ABoVE团队研究融化的永久冻土,湖泊

Since 2015, scientists participating in NASA’s Arctic Boreal Vulnerability Experiment (ABoVE) have been studying the impacts of climate change on Earth’s far northern regions and how those changes are intertwined. As our planet warms, permafrost—layers of soil that have stayed frozen for at least two years—thaws at an accelerating rate. This is changing the ...

地球近期的气候螺旋

2022年8月22日 Earth’s Recent Climate Spiral Video Credit: NASA’s Scientific Visualization Studio Explanation: Is our Earth warming? Compared to the past 250 million years, the Earth is currently enduring a relative cold spell, possibly about four degrees Celsius below average. Over the past 120 years, though, data indicate that the average global te...

美欧卫星将进行世界上第一次全球淡水调查

一旦卫星进入轨道,SWOT任务不仅将定期监测像俄勒冈州威拉米特这样的强大河流(如图),而且还将监测直径至少330英尺(100米)的小河流。 影像来源:美国能源部 地表水和海洋地形任务将对地球上95%以上的湖泊、河流和水库进行测量。 水就是生命,但尽管水很重要,但人类对地球淡水体的看法却出奇地有限。研究人员对全球仅有的几千个湖泊进行了可靠的水位测量,而地球上一些重要的河流系统几乎没有数据。即将到来的地表水和海洋地形(SWOT)卫星将填补这一巨大空白。通过帮助人们更好地了解地球的水循环,它将有助于更好地管理水资源,并扩大对气候变化如何影响湖泊、河流和水库的知识。 由NASA和法国航天局国家空间研究中心(CNES)合作,加拿大航天局和英国航天局提供捐助,SWOT计划于11月从加利福尼亚州范登堡航天部队基地发射。工程师...

地球资源卫星50周年

We’re celebrating 50 years of the Landsat satellite, the first of which launched on July 23, 1972. The latest in the series, Landsat 9, launched in September 2021. Landsat shows us Earth from space. For 50 years, the mission has collected data on the forests, farms, urban areas and freshwater of our home planet, generating the longest continuous record...
