The GRACE-FO satellites have been successfully launched to monitor the Earth’s water
A few hours ago, the two GRACE-FO twin spacecraft were launched on a Falcon 9 rocket from the Vandenberg base. After about ten minutes they successfully separated from the rocket’s last stage and entered a polar orbit. Shortly thereafter they started transmitting telemetry signals. SpaceX’s mission continued with the launch of 5 satellites of the Iridium constellation.
