Yesterday, less than 48 hours after the last Falcon 9 launch (from KSC’s LC-39A), a second Falcon 9 blasted off. This one launched from Vandenberg AFB’s SLC-4 and delivered the next ten Iridium Next satellites. Once enough Iridum Next spacecraft are delivered to orbit, they will begin to replace the famous initial constellation, which is nearing the end of its service life. Alas, the new spacecraft are much smaller than the original Iridiums and will not wow spotters with bright flares with each pass.
The Falcon 9 for this flight is a full thrust Falcon 9 equipped with a new, all-titanium set of grid fins. They’re heavier than the older ones, but can handle larger loads and provide more control authority. This will be critical when the Falcon Heavy’s three cores attempt to return later this year.
This spacecraft’s first stage was successfully recovered by the drone ship Just Read The Instructions, and will eventually be reflown.
