Falcon 9 launch timeline with Bangabandhu 1
May 11, 2018 | Stephen Clark

SpaceX's Falcon 9 rocket is set for liftoff from Cape Canaveral on Friday, heading due east over the Atlantic Ocean to deliver the Bangabandhu 1 communications satellite into orbit around 33 minutes later.

The 229-foot-tall (70-meter) rocket is poised for launch from pad 39A at NASA's Kennedy Space Center in Florida at 4:14 p.m. EDT (2014 GMT) Friday at the opening of a 127-minute launch window.

It will be the first launch of SpaceX's upgraded "Block 5" version of the workhorse Falcon 9 rocket, featuring changes to make the vehicle easier to reuse and more reliable.

Perched atop the rocket is the Bangabandhu 1 communications satellite, a spacecraft made by Thales Alenia Space for the Bangladesh Telecommunication Regulatory Commission. Bangabandhu 1 is the country's first communications satellite, and it is named for Bangabandhu Sheikh Mujibur Rahman, the father of the Bangladeshi nation.

The timeline below outlines the launch sequence for the Falcon 9 flight with Bangabandhu 1.

Data source: SpaceX

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 39A.

T+0:01:08: Mach 1


The Falcon 9 rocket reaches Mach 1, the speed of sound, as the nine Merlin 1D engines provide more than 1.7 million pounds of thrust.

T+0:01:14: Max Q


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

T+0:02:31: MECO


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

T+0:02:33: Stage 1 Separation


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

T+0:02:36: First Ignition of Second Stage


The second stage Merlin 1D vacuum engine ignites for a six-minute burn to put the rocket and Bangabandhu 1 into a preliminary parking orbit.

T+0:03:37: Fairing Jettison


The 5.2-meter (17.1-foot) diameter payload fairing jettisons once the Falcon 9 rocket ascends through the dense lower atmosphere. The 43-foot-tall fairing is made of two clamshell-like halves composed of carbon fiber with an aluminum honeycomb core.

T+0:06:15: Stage 1 Entry Burn


A subset of the first stage's Merlin 1D engines ignite for an entry burn to slow down for landing. A final landing burn will occur just before touchdown.

T+0:08:10: Stage 1 Landing


The Falcon 9 rocket's first stage booster touches down on SpaceX's drone ship in the Atlantic Ocean.

T+0:08:19: SECO 1


The second stage of the Falcon 9 rocket shuts down after reaching a preliminary low-altitude orbit. The upper stage and Bangabandhu 1 begin a coast phase scheduled to last more than 19 minutes before the second stage Merlin vacuum engine reignites.

T+0:27:38: Second Ignition of Second Stage


The Falcon 9's second stage Merlin engine restarts to propel the Bangabandhu 1 communications satellite into a supersynchronous transfer orbit.

T+0:28:37: SECO 2


The Merlin engine shuts down after a short burn to put the Bangabandhu 1 satellite in the proper orbit for deployment.

T+0:33:38: Bangabandhu 1 Separation


The Bangabandhu 1 satellite separates from the Falcon 9 rocket in a geostationary transfer orbit with a perigee of 186 miles (300 kilometers), an apogee of 22,186 miles (35,706 kilometers) and an inclination of 19.3 degrees.

T-minus 60 minutes and counting. Preparations to begin fueling SpaceX's Falcon 9 rocket at Kennedy Space Center are underway, with propellants set to start pumping abroad the launcher in the next half-hour. Liftoff is set for 4:14pm EDT (2014 GMT). https://spaceflightnow.com/2018/05/10/falcon-9-bangabandhu-1-mission-status-center/ ...

T-minus 40 minutes and counting. SpaceX has adjusted the countdown timeline for the upgraded "Block 5" version of the Falcon 9 rocket. Super-chilled, densified RP-1 kerosene and liquid oxygen propellants will start loading into the rocket at T-minus 35 minutes.

During countdowns for flights of the previous version of the Falcon 9 rocket, kerosene was loaded into the launcher beginning at T-minus 70 minutes, followed by the start of liquid oxygen tanking at T-minus 35 minutes.

No issues reported that would prevent an on-time start to fueling. #SpaceX #Falcon9 #Block5 #Bangabandhu1

T-minus 35 minutes and counting. "Launch auto has started."

The beginning of the launch autosequence kicks off the first steps to begin pumping propellants into the 229-foot-tall Falcon 9 at launch pad 39A.

RP-1 kerosene and liquid oxygen are now being pumped into the Falcon 9 rocket. The liquid oxygen is chilled to near minus 340 degrees Fahrenheit (minus 206 degrees Celsius).
