Liftoff of the l lth overall Starlink objective, and the tenth launch of the Version 1.0 satellites, is set up for 10:31 AM EDT (14:31 UTC) on Tuesday, August 18. Must the launch be postponed due to weather, a technical concern, or anything else, there is a backup launch chance offered on Wednesday. The eleventh Starlink mission will introduce from SLC-40 at Cape Canaveral Air Force Station, where B1049.6 finished a successful fixed fire test on August 17. In addition to a recycled first phase, the payload fairing for this launch has flown before on the 4th Starlink mission. Tuesdays countdown to launch starts 38 minutes before liftoff, when the SpaceX Launch Director gives the “go” for propellant load.

Liftoff of the eleventh overall Starlink mission, and the tenth launch of the Version 1.0 satellites, is set up for 10:31 AM EDT (14:31 UTC) on Tuesday, August 18. Needs to the launch be delayed due to weather, a technical issue, or anything else, there is a backup launch opportunity offered on Wednesday.
On board the flight are 58 of SpaceXs Starlink internet satellites, which will join the 531 v1.0 satellites currently on orbit. 535 of the v1.0 satellites have been introduced prior to Tuesdays launch, with 4 having actually destructively reentered, as developed, after coming across issues after launch.
The fleet of test satellites which informed the v1.0 style are likewise presently in the process of being deorbited for damaging reentries. The Tintin B satellite, one of two Tintin test satellites launched in 2018, reentered on August 8. Tintin As orbit is likewise rotting and expected to reenter Earths environment in the future.
Of the 60 v0.9 satellites introduced in 2019, 4 have actually reentered to date, with the staying 56 either actively deorbiting or naturally rotting. The Tintin and v0.9 satellites will not become part of the operational Starlink satellite constellation.
Joining the 58 Starlink v1.0 satellites on this launch are three SkySat Earth observation satellites for Planet Labs. The SkySat 19, 20, and 21 satellites will orbit Earth at 53 degrees disposition, enabling imaging of Earth between 53 degrees north and 53 degrees south latitude. These satellites will complement Planets fleet of satellites in Sun Synchronous Orbit.

The around 120 kilogram SkySats are launching as part of SpaceXs rideshare program. The ninth Starlink objective also brought 3 SkySats to orbit under this program, and SpaceX released two SkySats on Spaceflight Incs SSO-A rideshare objective in 2018.
See AlsoOther SkySats have introduced on the Indian PSLV, Arianespace Vega, and Northrop Grumman Minotaur-C launch cars. The SkySat constellation was originally operated by Skybox Imaging, which was relabelled Terra Bella prior to being acquired by Planet Labs in 2017.
The launch carrying the latest additions to the SkySat constellation will utilize the B1049.6 Falcon 9 booster. This is the very first time that a Falcon core will fly a 6th mission, having actually launched the Telstar 18 Vantage objective and the first, third, and 8th Starlink missions from SLC-40 in Florida. B1049 likewise launched the Iridium NEXT 8 objective from SLC-4E at Vandenberg Air Force Base in California.
The l lth Starlink objective will introduce from SLC-40 at Cape Canaveral Air Force Station, where B1049.6 finished a successful static fire test on August 17. After launch, the booster will attempt to arrive on the Of Course I Still Love You drone ship for a 4th time, about 634 kilometers downrange in the Atlantic Ocean. This will be B1049s 6th landing, consisting of two landings on Just Read the Instructions.

A successful launch and landing ought to put B1049 in line to continue exceeding by flying a seventh objective.
In addition to a recycled first phase, the payload fairing for this launch has actually flown prior to on the fourth Starlink objective. On that mission, one fairing half was captured on board the GO Ms. Tree recovery vessel, while the other was recuperated after a soft splashdown by GO Ms. Chief. Both GO Ms. Tree and GO Ms. Chief are positioned downrange again for healing efforts on the eleventh Starlink objective.
Tuesdays countdown to launch begins 38 minutes prior to liftoff, when the SpaceX Launch Director gives the “go” for propellant load. Assuming all the needed requirements are met, packing of RP-1 fuel into both stages and Liquid Oxygen into the very first stage starts 35 minutes before launch. Liquid Oxygen packing into the 2nd phase of Falcon 9 begins 16 minutes prior to launch.
Seven minutes before liftoff, the nine Merlin 1D engines on the very first stage are cooled in order to thermally condition the engines for ignition. One minute before launch, Falcon 9 gets in start-up, and begins pressurizing the cars propellant tanks to flight levels.
At T- 45 seconds, the SpaceX Launch Director provides a last confirmation that all systems are go for launch. 3 seconds prior to liftoff, the 9 Merlin 1D engines are commanded to begin the ignition series.
After raising off from SLC-40, Falcon 9 pitches downrange to start obtaining the horizontal velocity required to accomplish orbit. At T+ one minute and 12 seconds, the cars reaches the point of maximum vibrant pressure, or “Max Q,” where the aerodynamic tensions on the car reaches its peak. Prior to this point, tensions are progressively increasing as the rocket accelerates to greater velocities, however after Max Q, the thinning atmosphere at greater altitudes lead to reducing forces on the lorry.

The first phase engines shut down two minutes and 33 seconds after launch. A fairing healing attempt will be made pending appropriate weather conditions about 45 minutes after launch.
As the 2nd stage accelerates towards orbital velocity, the flight shown very first phase finishes a reentry burn at T+ 7 minutes and two seconds. B1049 then touches down aboard Of Course I Still Love You at T+ 8 minutes and 42 seconds, simply 9 seconds before the second phase closes down in orbit.
After a short coast phase, the three SkySat rideshare payloads are released at T+ 12:32, T+ 13:02, and T+ 13:32 respectively. The 2nd phase then cruises until 45 minutes and 57 seconds after liftoff before deploying the stack of 58 Starlink satellites.
Following the completion of the Starlink v1.0 L10 objective, SpaceX will turn their focus towards an approaching manifest that includes introducing the SAOCOM-1B satellite for CONAE. This launch will be the very first to use the polar launch passage because 1960, and is scheduled for no earlier than August 27 pending the launch of a ULA Delta IV Heavy bring the NROL-44 objective no earlier than August 26.
Other upcoming SpaceX missions consist of the SXM-7 and GPS-III-SV04 satellites, the first operational Crew Dragon objective, and more Starlink launches.

SpaceX is set to break another reuse record on the Starlink v1.0 L10 mission. For the very first time, a Falcon 9 very first stage will release a sixth objective, this one bring three rideshare payloads in addition to a batch of Starlink satellites.
