卫星激光揭示地球水运动的变化
GRACE-FO卫星上基于激光的仪器可以扩展到其他地球物理应用,用来收集地球系统中月内时间尺度上的质量变化的数据。
Fresh Approaches to Processing GRACE Data
Two studies showcase new methods for analyzing GRACE data that better match the land surface, producing clearer estimates of mass variations.
Satellites’ Lasers Reveal Changes in Earth’s Water Movement
The laser-based instruments aboard the GRACE-FO satellites may be extended to other geophysical applications to collect data on other submonthly mass changes in Earth’s system.
Tidally Locked and Loaded with Questions
Tidally locked planets always present the same face to their host stars. What does this mean for their potential to support life?
Can Uranus’s Rings Reveal the Planet’s Deepest Secrets?
Planetary rings can act as seismometers that respond to changes deep within a planet.
Can NASA’s Gravity Satellites Detect Motions in Earth’s Core?
Measurements of our planet’s gravitational field could expose processes in the fluid outer core—if scientists can decipher the signals.
Gravity Data Reveal Unexpected Antarctic Ice Variations
A new analysis of long-term satellite records shows the East Antarctic Ice Sheet is unexpectedly dependent on fluctuations in weather. This study may improve models of how much sea levels will rise.
A Better Understanding of How the Sun Bends Light
Incorporating the refractive index of the Sun into models of gravitational lensing effects improves agreement with measurements of the phenomenon.
Gravity Waves Leave Ripples Across a Glowing Night Sky
A thunderstorm made waves on a rare “bright night.”
