Week in Space Data, every Friday.
The webcast for Falcon 9 · Crew-16 appears here once the provider posts it.
A typical Falcon 9 flight, with typical times. Every mission differs, and this is a guide, not live tracking: nothing here is ticked off by the clock.
The launch vehicle is vertical on the pad. Ground crews perform final inspections, range safety checks, and verify all telemetry links. Weather balloons are launched to check upper-level winds.
RP-1 kerosene and liquid oxygen (LOX) are loaded into the first and second stages. LOX loading continues until just before launch due to boil-off. The strongback retracts to launch position.
Automated launch sequence begins. Flight computers take over countdown. Final range safety checks, propellant pressurization, and engine chill procedures are completed. Launch director polls all stations for GO.
Nine Merlin 1D engines ignite generating 1.7 million pounds of thrust. The vehicle is released from hold-down clamps at T+0 and begins its ascent. The vehicle clears the tower within seconds.
The vehicle passes through the region of maximum aerodynamic stress at approximately 35 kPa. Engines throttle down to ~70% to reduce structural loads, then throttle back up after passing through Max-Q.
All nine first-stage engines shut down after accelerating the vehicle to approximately 2.3 km/s. The first stage has burned through most of its propellant. Brief coast phase begins before stage separation.
Pneumatic pushers separate the first and second stages. Cold gas thrusters orient the first stage for its return journey. The interstage separates cleanly, allowing the second stage engine to ignite safely.
The single Merlin Vacuum engine ignites in the near-vacuum of space. Its extended nozzle is optimized for vacuum operation, producing 981 kN of thrust. This burn will place the payload into its target orbit.
The two halves of the payload fairing separate and fall away, exposing the payload to space. The fairing is no longer needed as the vehicle is above the sensible atmosphere. Fairings may be recovered by ships at sea.
The second stage engine shuts down after achieving the target orbital velocity of approximately 7.8 km/s. The payload is now in its target orbit at approximately 250 km altitude.
The payload separates from the second stage adapter. Springs or motorized mechanisms push the satellite away from the rocket. The satellite deploys solar panels and begins its own mission.
The first stage performs a series of burns: boostback burn to reverse trajectory, entry burn to slow down through the atmosphere, and a single-engine landing burn. Grid fins steer the booster to a precision landing on a drone ship or landing pad.
All primary mission objectives have been achieved. The payload is confirmed in its target orbit with healthy telemetry. The first stage has been recovered (if applicable). Mission success declared.
Chat opens two hours before liftoff once the launch time is set.
Telemetry and trajectory data shown is simulated for demonstration purposes. Real telemetry data would require integration with launch provider APIs.
Every entry is a change we recorded, not a forecast. Our sync checks Launch Library 2 every 15 minutes, so a time is when we saw the change and can trail the real moment. The liftoff time is the one the launch record states.
Nothing has changed on this launch since we started recording it. Status changes, date moves and the liftoff will appear here as they are recorded.
Falcon 9 (SpaceX)
Falcon 9 is a two-stage rocket: nine Merlin engines on the first stage and one Merlin Vacuum engine on the second, all burning kerosene and liquid oxygen. The first stage is reusable and flies many times.
On a crewed flight the capsule carries a launch escape system that can pull the crew away from the rocket at any point during the climb. After the upper stage shuts down, the capsule separates and flies on under its own power.
