Falcon 9 Block 5 | 9 x Globalstar-3

The Globalstar global mobile communications network offers global, digital real time voice, data and fax services via its Low Earth Orbit satellite constellation. The constellation operates in a 1410 km orbit inclined at 52 degrees.
In early 2022, Globalstar contracted with MDA for the construction of 17 new 3rd generation satellites to replenish the existing constellation. Rocket Lab is sub-contracted to build the satellites' buses and the launch dispensers.

Launch Timeline
expand_circle_down
Go for Prop Load
Launch Director gives go for propellant load.
Prop Load
Loading of RP-1 (kerosene) and liquid oxygen (LOX) begins.
Engine Chill
Liquid oxygen flows through the engines to condition them for ignition.
Startup
Flight computer takes control; propellant tanks pressurize for flight.
Go for Launch
Final verification from Launch Director.
Ignition
The 9 Merlin engines ignite.

Liftoff
Rocket clamps release; Falcon 9 lifts off.
Max Q
Peak aerodynamic pressure (maximum mechanical stress).
MECO
Main Engine Cutoff: first stage engines shut down.
Stage Separation
Booster separates from the second stage.
SES-1
Second stage engine start (Merlin Vacuum ignition).
Fairing Jettison
Payload fairing separates (not applicable for Dragon missions).
Booster Flip Maneuver
First stage flips 180° using attitude control thrusters for reentry.
Second Stage Ascent
Second stage continues accelerating toward orbital velocity.
Booster Entry Burn
Three engines fire to slow the booster during atmospheric entry.
Second Stage Burn
Second stage engine continues burning toward the target orbit.
Booster Landing Burn
Single center engine fires to decelerate for landing.
SECO-1
Second Engine Cutoff: parking orbit achieved.
Booster Touchdown
Booster lands on the recovery platform (e.g., a drone ship).
Coasting
Vehicle coasts in orbit before deployment or further burns.
Crew Dragon Separation (typical)
Crew Dragon separates from the second stage (typical timing).
GTO Deployment (typical)
After coasting and a restart (SES-2), payload deploys (typical timing).
Starlink Deployment Window (typical)
Deployment timing varies by mission; this is a typical window.
