Launch Alert!: Thursday, April 11, 2019, at 18:35 EDT (15:35 PDT & 22:35 UTC) SpaceX will be launching their massive Falcon Heavy (F9H) from Kennedy Space Center, Launch Complex 39A (LC-39A) carrying the Arabsat 6A communication satellite for Arabsat of Saudi Arabia.

This will be the second launch of the Falcon Heavy and the first flight of their Block 5 iteration. This flight will use three new unflown block 5 boosters. The center booster will be core (B1055.1) the port (left) booster is (B1052.1) and the starboard (right) booster is (B1053.1).

With 22,819 kN (5.1 million lb.) of thrust at liftoff, the Falcon Heavy is the most powerful rocket since the Saturn V. With no “asparagus staging” propellant crossfeeding, instead the core booster will throttle down to preserve fuel while the port and starboard boosters do most of the initial lifting. After separation, the core booster will throttle back up for completion of its mission.

Stats: This will be SpaceX’s 4th launch of 2019 and the 76th SpaceX flight overall (5 Falcon 1, 69 Falcon 9, 2 Falcon Heavy). Mission parameters will allow for two boosters (port and starboard) to return to Landing Zone 1 (LZ-1 & former SLC-13) at Cape Canaveral while the core booster touched down on SpaceX’s East Coast Autonomous Spaceport Drone Ship (ASDS) “Of Course I Still Love You (OCISLY)” which will bring to total successful landings to 38; 23 on drone ships and 15 on land.

Autonomous Spaceport Drone Ships (ASDS): Were built at the Conrad Shipyard in Morgan City, Louisiana, the same place that NASA’s Pegasus barge was refitted to support the SLS program. Pegasus carried lots of equipment throughout the years but most famously the space shuttle external fuel tanks from NASA’s Michaud Plant in Louisiana to KSC.

SpaceX’s barges are 300 by 100 ft. with “wings” that extend that width to 170 ft. It has also been fitted with thrusters repurposed from deep sea oil rigs that are able to hold balance and position to within 3 meters even in storm conditions. ASDS’s are painted black with the SpaceX “X” logo, a yellow inner ring and outer white ring acting as a bull eye. The East Coast ASDS is “Of Course I Still Love You (OCISLY)” and the West Coast’s ship is “Just Read The Instructions (JRTI).”

In total there have been three ASDS’s. The first of which was Marmac 300, a deck barge named “Just Read The Instructions (JRTI).” That ASDS was used for two east coast landing attempts (CRS 5 & 6), deconstructed and retired. East Coast duties were then transferred to Marmac 304 named “Of Course I Still Love You (OCISLY).” A third ASDS, Marmac 303 was constructed and stationed on the West Coast where it fields launches from Vandenberg AFB, CA. Its name, “Just Read The Instructions (JRTI).”

These fun yet odd names come from Scottish Sci-fi legend Iain Banks’s “Culture” series of 10 novels. They are spacecraft known as General Contact Units (GCU’s) from the novel “Player of Games.” Other spacecraft in the series (which get to name themselves) are even more entertaining such as “Size Isn’t Everything,” “No More Mr. Nice Guy” and “Death and Gravity.” Here’s a fun Wiki page with more info: http://en.wikipedia.org/wiki/List_of_spacecraft_in_the_Culture_series

The Rocket and Performance: SpaceX Falcon Heavy

Height: 70m (229.6 ft.)

Core Diameter: 3.66 m (12 ft.)

Width: 12.2 m (39.9 ft.)

Stages: 2

Boosters: 2

Total Engines: 28 (27 in the first stage and 1 in the second stage)

Total Thrust (sea level): 22,819 kN (5.13 million lb.) or about eighteen 747s at full power. Only the Saturn V can deliver more t orbit than the Falcon Heavy.

Mass: 1,420,788 kg (3,125,735 lb.)

Payload to Low Earth Orbit (LEO): 63,800 kg (140,660 lb.) which is almost three times that of the Space Shuttle’s 24,000 kg (53,790 lb.) and Delta IV Heavy’s 22,560 kg (49,740 lb.) For scale, the Falcon Heavy can deliver a fully loaded Boeing 737 complete with fuel, luggage and passengers into orbit.

Payload to Geostationary Transfer Orbit (GTO): 26,700 kg (58,860 lb.)

Payload to Mars: 16,800 kg (37,040 lb.)

Cost: About $90 million per launch which is much less than the $400 million per launch of the Delta IV Heavy.

Dragon Spacecraft (when in use): The Dragon spacecraft is about 23.6 ft. (7.2 m) tall with trunk attached and 12 ft. (3.7 m) wide. It’s comprised of two main sections; the pressurized cargo area which can carry 388 cubic ft. of cargo as well as the unpressurized cargo area. The trunk (unpressurized area) carries 494 cubic ft. of cargo as well as the solar arrays. Dragon, along with Russia’s Progress & Soyuz, Europe’s (ESA) Automated Transfer Vehicle (ATV), Orbital ATK’s Cygnus and Japan’s (JAXA) H-II Transfer Vehicle (HTV), is one of only six vehicles that can fly to the Space Station. While Russia’s Soyuz is currently the only crewed means of reaching and returning from Station, SpaceX’s Dragon is currently the only means of returning experiments and supplies back to Earth from Station.

Main Composite Payload Fairing (when in use): the two shell, composite payload fairing is 13 m (43 ft.) in length and 5.2 m (17 ft.) in diameter. The fairings are used to protect the spacecraft during ascent through atmospheric turbulence and into space. Once the rocket has reached a safe altitude the fairings jettisoned, exposing the spacecraft(s).

SpaceX Falcon 9/Falcon Heavy Second Stage:

Height: 10 m. (33 ft.)

Diameter: 3.66 m (12 ft.)

Engine(s): Single Merlin Vacuum Engine

Engine Chambers: 1

Engine Type: Gas generator

Propellant Feed: Turbopump

Chamber Pressure: More than 100 bar

Fuel Type: Liquid

Fuel: Chilled Rocket propellant-1 (RP-1) or highly refined kerosene. Lower specific impulse than liquid hydrogen (LH2) but is cheaper, room temperature stable, less explosive and denser. RP-1 is much more powerful than LH2 by volume and much less toxic than other room temperature fuels such as hydrazine (N2H4).

Oxidizer: Subcooled Liquid Oxygen (LOX). LOX is often coupled with rocket propellant-1 (RP-1), liquid hydrogen (LH2) and methane (CH4) as it creates a high specific impulse.

Thrust (vacuum): 934 kN (210,000 lbf.)

Specific Impulse (vacuum): 348 s

Burn Time: 397 s

Restart Ability: Yes

Reusable?: No

SpaceX Falcon 9/Falcon Heavy Interstage:

The interstage is a 4.4m (14.4 ft.) composite structure that connects the first stage to the second stage and holds the release and separation system. It’s an all pneumatic stage separation system for low shock, highly reliable separation that can be tested on the ground, unlike pyrotechnic systems used on most launch vehicles.

SpaceX Falcon Heavy Core & Boosters First Stage:

Height: 47 m. (154 ft.)

Diameter: 3.66 m (12 ft.)

Width: 12.2 m (39.9 ft.)

Engine(s): 27 Merlin 1D Engines

Engine Chambers: 1

Engine Type: Gas generator/Open-cycle

Propellant Feed: Turbopump

Chamber Pressure: More than 100 bar

Fuel Type: Liquid

Fuel: Chilled Rocket propellant-1 (RP-1) or highly refined kerosene. Lower specific impulse than liquid hydrogen (LH2) but is cheaper, room temperature stable, less explosive and denser. RP-1 is much more powerful than LH2 by volume and much less toxic than other room temperature fuels such as hydrazine (N2H4).

Oxidizer: Subcooled Liquid Oxygen (LOX). LOX is often coupled with rocket propellant-1 (RP-1), liquid hydrogen (LH2) and methane (CH4) as it creates a high specific impulse.

Single Merlin 1D Thrust (sea level/vacuum): 845 kN (189,964 lbf.)/914 kN (205,475 lbf.

Total Thrust (sea level): 22,819 kN (5.13 million lbf.)

Specific Impulse (sea level/vacuum): 282 s/311 s

Burn Time: 162 s per core though the center core will be throttled down in flight to save fuel then throttle back up after port and starboard separation.

Restart Ability: Partially (1 or 3 engines can restart for landing actions)

Reusable?: Yes

First stage boosters are fitted with four independently steerable titanium grid fins that help control pitch, yaw and roll during vertical decent as well as four landing legs that extend before touchdown.
