Iridium-2 NEXT Mission Mission Overview SpaceX’s Falcon 9 rocket will deliver 10 satellites to lowEarth orbit for Iridium, a global leader in mobile voice and data satellite communications. This is the second set of 10 satellites in a series of 75 total satellites that SpaceX will launch for Iridium’s next generation global satellite constellation, Iridium® NEXT. SpaceX is targeting launch of Iridium-2 from Space Launch Complex 4E (SLC-4E) at Vandenberg Air Force Base in California. The instantaneous launch window is at 1:25 p.m. PDT, or 20:25 UTC, on Sunday, June 25. The satellites will begin deployment about an hour after launch. Following stage separation, the first stage of Falcon 9 will attempt a landing on the “Just Read the Instructions” droneship that will be stationed in the Pacific Ocean.
