Iridium Communications Inc. announced today that the seventh Iridium NEXT mission has been targeted by SpaceX for launch on July 20, 2018, from Vandenberg Air Force Base in California.

The Falcon 9 rocket will launch 10 Iridium NEXT satellites to low Earth orbit (LEO) from Vandenberg Air Force Base (VAFB) in California at approximately 5:12 am PDT (12:12 UTC). An exact instantaneous launch window time will be available closer to the launch date. As the second-to-last launch of the planned Iridium NEXT program, this mission will increase the total number of Iridium NEXT satellites in space to 65.

All 10 satellites for this mission will be deployed to Iridium orbital plane number 5 where they will go into operation immediately following a thorough testing and validation process.  The Iridium network is comprised of six polar orbiting planes, each containing 11 operational crosslinked satellites, for a total of 66 satellites in the active constellation. Once all the satellites from the Iridium-7 mission are operational, plane 5 will be the fourth orbital plane to be comprised entirely of Iridium NEXT satellites.  In total, 81 Iridium NEXT satellites are being built, with 66 in the operational constellation, nine serving as on-orbit spares and six serving as ground spares.
