GRACE-FO launched SpaceX

Using the same booster that launched the failed Zuma, it lofted two GRACE-FO satellites and five Iridium:

• No recovery of first stage planned
• Flairing recovery attempted but no luck
• Satellites released on orbit

. . . Major changes in water mass can cause localized bumps and dips in gravity, sometimes with counterintuitive effects. Melting glaciers, for example, actually cause nearby sea level to drop; as they lose mass, their gravitational pull slackens, and sea water migrates away. In this animation, computed from data gathered by the twin GRACE satellites between April 2002 and March 2015, sea level is dropping around rapidly melting Greenland (orange, yellow). But near coastlines at a sufficient distance, the added water causes sea levels to rise (blue). The computational method is described in Adhikari et al. (2016, Geoscientific Model Development). And, these solutions are presented in Adhikari and Ivins (2016, Science Advances).​
