On 25 June, they launched the second batch during SpaceX's "weekend doubleheader" when it launched back-to-back Falcon 9 rocket launches and landings in just 48 hours.
This evening's mission will be powered by a first stage booster that was used for a previous launch in February. A few minutes after liftoff, SpaceX managed to nail the landing of the Falcon 9 rocket's first stage on the droneship named "Just Read the Instructions" in the Pacific Ocean. For a nascent technology offering as complex as a reused rocket, this ought to assuage any doubts that SpaceX is not utterly committed to its pursuit of affordable access to orbit by way of launch vehicle reusability.
The present launch is commonplace to SpaceX since the organization has essentially done it sometime recently.
SpaceX launched the third set of Iridium NEXT communications satellites into orbit from Vandenberg Air Force Base, Calif., Oct. 9. The rest will keep on being propelled in 10-satellite augmentations throughout the following year, alongside one launch of five.
"Each successful launch brings us one step closer to both a technological and financial transformation", Iridium CEO Matt Desch said in a statement.
The satellite is called EchoStar 105/SES-11 and was built by Luxembourg-based operator Société Européenne des Satellites (SES). The present launch is slated for 8:37 AM ET and SpaceX have a prompt launch window, so the organization must launch around then or reschedule. Up until this point, the climate is looking entirely useful for launch, with a 90 percent chance that conditions will be positive.
