Falcon Heavy Demonstration Mission

Post by Christopher K. » February 6th, 2018, 1:08 pm

Today at 2:05pm CST, SpaceX will test the ability of its new Falcon Heavy system to launch and successful return to Earth. The Falcon Heavy, if successful, will have the ability to lift into orbit payloads with masses greater than a fully-loaded Boeing 737. SpaceX is attempting to create a cargo transportation system "with the ability to lift more than twice the payload of the next vehicle at one-third the cost".

Falcon Heavy has three cores; one on the pad today launched the Thaicom 8 satellite, and another supported the CRS-9 mission. After booster separation, the two sides cores will land at SpaceX Landing Zones 1 and 2 (at Cape Canaveral) and the central core will land on the Of Course I Still Love You" droneship stationed in the Atlantic Ocean. At least, that's the plan! Today's test payload is a Tesla Roadster.

SpaceX has pushed to launch to 2:45pm CST. Below is the expected countdown timeline...
-01:28:00 = SpaceX Launch Director verifies go for propellant load
-01:25:00 = RP-1 (rocket grade kerosene) loading underway
-00:45:00 = LOX (liquid oxygen) loading underway
-00:07:00 = Falcon Heavy begins engine chill prior to launch
-00:01:00 = Flight computer commanded to begin final prelaunch checks
-00:01:00 = Propellant tank pressurization to flight pressure begins
-00:00:45 = SpaceX Launch Director verifies go for launch
-00:00:05 = Engine controller commands side booster engine ignition sequence to start
-00:00:03 = Engine controller commands center core engine ignition sequence to start
-00:00:00 = Falcon Heavy liftoff
