Launch timeline for SpaceX's 15th space station resupply mission
June 28, 2018 | Stephen Clark

SpaceX's Falcon 9 rocket will go from Cape Canaveral to low Earth orbit in less than 10 minutes Friday with a Dragon capsule heading for the International Space Station carrying more than 5,900 pounds of supplies and experiments.

Liftoff is set for 0942 GMT (5:42 a.m. EDT) Friday from Cape Canaveral's Complex 40 launch pad.

It will be the 57th flight of a Falcon 9 rocket, and SpaceX's 12th launch of the year. Working under contract to NASA, Friday's launch will be the 15th of least 26 SpaceX resupply missions to depart for the space station.

SpaceX does not intend to recover the Falcon 9 rocket's first stage on Friday's mission. The booster is already a veteran of one launch in April, when it propelled NASA's Transiting Exoplanet Survey Satellite toward orbit.

T-0:00:00: Liftoff


After the rocket's nine Merlin engines pass an automated health check, hold-down clamps will release the Falcon 9 booster for liftoff from pad 40.

T+0:01:10: Mach 1


The Falcon 9 rocket reaches Mach 1, the speed of sound.

T+0:01:19: Max Q


The Falcon 9 rocket reaches Max Q, the point of maximum aerodynamic pressure.

T+0:02:45: MECO


The Falcon 9's nine Merlin 1D engines shut down.

T+0:02:48: Stage 1 Separation


The Falcon 9's first stage separates from the second stage moments after MECO.

T+0:02:56: Second Stage Ignition


The second stage Merlin 1D vacuum engine ignites for an approximately five-and-a-half-minute burn to put the Dragon spacecraft into orbit.

T+0:08:31: SECO


The second stage of the Falcon 9 rocket shuts down after reaching a target orbit with a low point of approximately 124 miles (200 kilometers), a high point of approximately 223 miles (360 kilometers) and an inclination of 51.6 degrees. The second stage will reignite for a de-orbit burn after a long-duration coast demonstration, falling back into the atmosphere over the Atlantic Ocean for a destructive re-entry around six hours after liftoff.

T+0:09:31: Dragon Separation


The Dragon spacecraft separates from the Falcon 9 rocket's second stage.

T+0:11:00: Solar Arrays Deployed


The Dragon spacecraft's two solar array wings extend one-at-a-time to a span of 54 feet (16.5 meters).

The launch auto-sequence has started, and densified, super-chilled RP-1 kerosene is now being loaded into the Falcon 9 rocket.

This is the 3rd and FINAL Block 4 first stage / Block 5 second stage Falcon 9 configuration. It is also the LAST Block 4 booster to fly. All Falcons from here on will be Block 5s.

T-1hr. All is well with the early stages of RP-1 (rocket-grade kerosene) fueling of the 1st stage.

This is also the 1st time #Dragon and #NASA are flying with a Block 5 2nd Stage of the #Falcon9 -- the first time NASA uses any #Block5 iteration of the Falcon 9 (but not the last).

~1 hour until Falcon 9 launch of Dragon for its fifteenth mission to the @Space_Station. Vehicle and spacecraft are healthy and tracking no issues

Extra performance of Block 5 2nd Stage results in 32 second shorter ascent for orbital insertion of #Dragon. CRS-14 took 9mins 3secs to reach orbit on an all-Block 4 #Falcon9. #CRS15 today will take only 8mins 31secs to reach orbit under Block 5 Stage 2 power.

T-45mins and COUNTING. All continues to go well. We are 10mins away from the start of Stage 1 LOX (Liquid Oxygen) load and Stage 2 RP-1 load. Stage 2 LOX load will follow later in the count.
