Follow the key events of the Falcon 9 rocket’s ascent into space from Cape Canaveral with the Eutelsat 115 West B and ABS 3A communications satellites.
Launch is set for 10:50 p.m. EST on March 1 (0350 GMT on March 2) from Cape Canaveral’s Complex 40 launch pad. The satellites will be deployed in a supersynchronous transfer orbit with perigee of approximately 400 kilometers (250 miles), an apogee of 63,000 kilometers (39,146 miles) and an inclination of 24.8 degrees.
Updated March 1 with correct orbit targets.

T-0:00:00: Liftoff
After the rocket’s nine Merlin engines pass an automated health check, four hold-down clamps will release the Falcon 9 booster for liftoff from Complex 40.
T+0:01:13: Mach 1
The Falcon 9 rocket reaches Mach 1, the speed of sound.
T+0:01:24: Max Q
The Falcon 9 rocket reaches Max Q, the point of maximum aerodynamic pressure.
T+0:02:56: MECO
The Falcon 9’s nine Merlin 1D engines cut off.
T+0:02:58: Stage 1 Separation
The Falcon 9’s first stage separates from the second stage moments after MECO.
T+0:03:06: Stage 2 Ignition
The second stage Merlin 1D vacuum engine ignites for an approximately 6-minute burn.
T+0:03:51: 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+0:08:50: SECO 1
The second stage of the Falcon 9 rocket shuts down after completing the first of two burns.
T+0:25:42: Second Stage Restart
The second stage Merlin 1D vacuum engine reignites for a brief firing to place the payload in the correct orbit for deployment.
T+0:26:41: SECO 2
The Falcon 9’s vacuum-rated Merlin engine shuts down after a second burn.
T+0:30:08: ABS 3A Separation
The ABS 3A spacecraft, with a launch mass of approximately 2,000 kilograms (4,400 pounds), deploys from the dual-payload stack on the Falcon 9 rocket.
T+0:35:08: Eutelsat 115 West B Separation
The Eutelsat 115 West B satellite, with a launch mass of about 2,200 kilograms (4,850 pounds), deploys from the Falcon 9 rocket.
NASA expects to select commercial contractors to resupply the International Space Station in September, three months later than the agency’s previous timetable under a competition for cargo deliveries beginning in 2018.
A commercial lunar lander built by Astrobotic will launch from the Kennedy Space Center on a SpaceX Falcon Heavy rocket in late 2023 to deliver a water-hunting NASA rover to the moon’s south pole, officials announced Tuesday.
SpaceX is preparing to launch another batch of satellites for the Starlink Internet network from Florida’s Space Coast as soon as April 16, a sign that launch operations at Cape Canaveral could continue at a reduced pace amid the global coronavirus pandemic.
