Falcon 9 Orbits Iridium-NEXT, GRACE-FO Satellites
A SpaceX Falcon 9 booster blasted off from Vandenberg Air Force Base on Tuesday afternoon and successfully orbited seven satellites.
There were five Iridium-NEXT communications satellites aboard. These were the 51st through 56th Iridium-NEXT spacecraft orbited by Falcon 9 boosters.
A pair of Gravity Recovery and Climate Experiment Follow-On (GRACE-FO) satellites were also onboard. The spacecraft will measure changes in how mass is redistributed within and among Earth’s atmosphere, oceans, land and ice sheets, as well as within Earth itself.
The mission is a join collaboration of NASA and the German Research Centre for Geosciences (GFZ). GFZ reports receiving signals from both GRACE-FO satellites.
