Follow the key events of the Falcon 9 rocket’s ascent to orbit with the Formosat 5 Earth observation satellite for Taiwan’s National Space Organization.
The 229-foot-tall (70-meter) rocket will lift off Saturday at 11:50 a.m. PDT (2:50 p.m. EDT; 1850 GMT) from Vandenberg Air Force Base in California.

T-0:00:00: Liftoff
After the rocket’s nine Merlin 1D engines pass an automated health check, the Falcon 9 is released from Space Launch Complex 4-East at Vandenberg Air Force Base, California.
T+0:01:09: Max-Q
The Falcon 9 rocket reaches Max Q, the point of maximum aerodynamic pressure. The first stage’s nine Merlin 1D engines produce about 1.7 million pounds of thrust.
T+0:02:28: MECO
The Falcon 9’s nine Merlin 1D engines shut down.
T+0:02:32: Stage 1 Separation
The Falcon 9’s first stage separates from the second stage moments after MECO.
T+0:02:39: Stage 2 Ignition
The second stage Merlin 1D vacuum engine ignites for an approximately six-and-a-half minute burn to guide the Formosat 5 satellite into orbit.
T+0:02:53: 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+0:08:45: 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+0:09:17: SECO 1
The Merlin 1D vacuum engine turns off after placing the Formosat 5 satellite into its planned sun-synchronous orbit.
T+0:10:47: Stage 1 Landing
The Falcon 9 rocket’s first stage booster touches down on SpaceX’s drone ship in the Pacific Ocean.
T+0:11:18: Formosat 5 Separation
The Formosat 5 spacecraft deploys from the Falcon 9 rocket’s upper stage to begin its five-year Earth observation mission.
Expertise, input and advice from seasoned NASA engineers will improve SpaceX’s chances of nailing the first commercial landing on Mars as soon as late 2018, a senior space agency official said Wednesday, but Elon Musk’s space transport company will likely seek more independence from U.S. government support on later expeditions to the red planet.
SpaceX launched an unpiloted Crew Dragon spacecraft aboard a Falcon 9 rocket from pad 39A at the Kennedy Space Center at 10:30 a.m. EST (1530 GMT) Sunday. SpaceX triggered an escape maneuver using the Dragon’s thrusters about a minute-and-a-half after liftoff to verify the launch abort engines can safely carry the capsule — and astronauts on future missions — away from a failing rocket.
Loaded with more than 6,000 pounds of supplies, experiments, and hardware, a SpaceX Cargo Dragon freighter docked with the International Space Station at 1:40 p.m. EST (1840 GMT) Monday, one day after taking off from NASA’s Kennedy Space Center in Florida. This was the first Dragon cargo mission to automatically dock with the space station.
