In this flight, the Falcon 9 rocket will deliver the THAICOM 6 satellite to a Geosynchronous Transfer Orbit (GTO). THAICOM 6 is a commercial telecommunications satellite. The THAICOM 6 launch window will open at approximately 5:06 p.m. EST on January 6, 2014 from Space Launch Complex 40 at Cape Canaveral Air Force Station, Florida, with additional launch opportunities January 7-12, 2014. If all goes as planned, the THAICOM 6 satellite will be deployed into its geosynchronous transfer orbit approximately 31 minutes after liftoff. Satellite Payload THAICOM 6 The THAICOM 6 mission will launch the THAICOM 6 commercial telecommunications satellite, an Orbital Sciences GEOStar-2 spacecraft. This hybrid Ku- and C-band spacecraft weighs 3,016 kg (6,649 lbs) at launch. This mission is the second Falcon 9 launch to a geosynchronous transfer orbit, targeting a 295 x 90,000 km orbit at 22.5 degrees inclination. THAICOM 6 will be co-located with THAICOM 5 at 78.5 degrees East (“Hot Bird†position), and carry a hybrid Ku- and C- band payload generating approximately 3.7 kilowatts of payload power. The Ku-band payload will be comprised of 8 active transponders providing services to the Southeast Asia (mainland). The C-band payload will feature 18 active C- band transponders providing services via the satellite’s regional beam to Southeast Asia and Africa, including Madagascar. Always a Challenging Mission All spaceflight is incredibly complicated. Every component of the mission must operate optimally. Hardware, avionics, sensors, software and communications must function together flawlessly. If any aspect of the mission is not successful, SpaceX will learn from the experience and try again. Prelaunch Months before a Falcon 9 launch, both rocket stages are transported to SpaceX’s development facility in McGregor, Texas for testing, and then trucked individually to SpaceX’s hangar at Space Launch Complex 40 at the Cape Canaveral Air Force Station in Cape Canaveral, Florida. SpaceX’s payload fairing is shipped separately to the launch site. Around 30 days before launch, the spacecraft arrives at SpaceX’s SLC-40 hangar annex. In the days that follow, the spacecraft is processed and encapsulated within the fairing, and the rocket stages are integrated. 4 The final major preflight test is a static fire, when Falcon 9’s nine first-stage engines are ignited for a few seconds, with the vehicle held securely to the pad. One day prior to launch, Falcon 9 and its payload are transported to the launch pad and raised vertically. All ground personnel leave the pad in preparation for fueling of the launch vehicle. Launch Sequence The launch sequence for Falcon 9 is a process of precision necessitated by the rocket’s approximately one-hour launch window, dictated by the desired orbit for the satellite. If the one-hour time window is missed, the mission will be attempted on the next available date. A little less than four hours before launch, the fueling process begins— liquid oxygen first, then RP-1 kerosene propellant. The plume coming off the vehicle during countdown is gaseous oxygen being vented from the tanks, which is why the liquid oxygen is topped off throughout the countdown. Terminal countdown begins at T-10 minutes, at which point all systems are autonomous. The SpaceX Launch Director at the Cape Canaveral Air Force Station gives a final go for launch at T-2 minutes and 30 seconds. At T-2 minutes, the Air Force Range Control Officer confirms the physical safety of the launch area and provides the final range status. Just before liftoff, the launch pad’s water deluge system, dubbed “Niagara,†is activated. Seconds before launch, the nine Merlin engines of the first stage ignite. The rocket computer commands the launch mount to release the vehicle for flight, and at T-0 Falcon 9 lifts off, putting out 1.3 million pounds of thrust. Flight The vehicle will pass through the area of maximum aerodynamic pressure—max Q—approximately 80 seconds into flight. This is the point when mechanical stress on the rocket peaks due to a combination of the rocket’s velocity and resistance created by the Earth’s atmosphere. Approximately 174 seconds into flight, the first-stage engines are shut down, an event known as main-engine cutoff, or MECO. Three seconds after MECO, the first and second stages will separate. Seven seconds later, the second stage’s single Merlin vacuum engine ignites to begin a 5 minute, 35 second burn that brings the satellite into a parking orbit. The fairing that protects the payload is deployed early in this burn. Eighteen minutes after injection into the parking orbit, the second stage will relight for just over one minute to carry the payload to its geosynchronous transfer orbit. Satellite Deployment Approximately three minutes after the second burn (at the 31 minute, 13 second mark after launch), the THAICOM 6 satellite is deployed into orbit. 5 THAICOM 6 Mission Timeline Times and dates are subject to change LAUNCH DAY COUNTDOWN Hour:Min:Sec Events - 13:30 Vehicle is powered on - 3:50 Commence loading liquid oxygen (LOX) - 3:40 Commence loading RP-1 (rocket grade kerosene) - 3:15 LOX and RP-1 loading complete - 0:10 Falcon 9 terminal count autosequence started - 0:02 SpaceX Launch Director verifies go for launch - 0:02 Range Control Officer (USAF) verifies range is go for launch - 0:01 Command flight computer to begin final prelaunch checks.

QUICK FACTS Made in America. All of Falcon 9’s structures, engines, and ground systems were designed, manufactured, and tested in the United States by SpaceX. 21st-century rocket. As the first rocket completely developed in the 21st century, Falcon 9 was designed from the ground up for maximum reliability. An upgraded Falcon 9 with safety and reliability enhancements and greater lift capability flew for the first time in December 2013, lofting the SES-8 satellite to a geosynchronous transfer orbit , and will fly on this mission. Designed for maximum reliability. Falcon 9 features a simple two-stage design to minimize the number of stage separations. (Historically, the main causes of launch failures have been stage separations and engine failures.) With nine engines on the first stage, it can safely complete its mission even in the event of an engine shutdown. Statistics. Falcon 9 topped with SpaceX fairing is 224.4 feet (68.4 meters) tall and 12 feet in diameter (the fairing is 17 feet in diameter). Its nine first-stage Merlin engines generate 1.3 million pounds of thrust at sea level, rising to 1.5 million pounds of thrust as Falcon 9 climbs out of the Earth’s atmosphere. In demand. SpaceX has nearly fifty Falcon 9 missions on its manifest, with launches for both commercial and government clients. Designed to safely transport crew. Like the Dragon spacecraft, Falcon 9 was designed from the outset to transport crew to space. Mission success. Falcon 9 has achieved 100% success on its flights to date, including routine flights to the International Space Station and most recently the successful December 2013 launch of the SES-8 satellite to geosynchronous transfer orbit. Why “Falcon� Falcon 9 is named for the Millennium Falcon in the “Star Wars†movies. The number 9 refers to the nine Merlin engines that power Falcon 9’s first stage; one Merlin vacuum engine powers the second stage. 7 ADVANCED TECHNOLOGY First Stage Falcon 9 tanks are made of aluminum-lithium alloy, a material made stronger and lighter than aluminum by the addition of lithium. Inside the two stages are two large tanks each capped with an aluminum dome, which store liquid oxygen and rocket-grade kerosene (RP-1) engine propellants. The tanks and domes are fabricated entirely in-house by SpaceX. Sections of aluminum are joined together using SpaceX’s custom-made friction stir welders to execute the strongest and most reliable welding technique available. The structures are painted in-house by SpaceX, concurrent with the welding process. Falcon 9’s first stage incorporates nine Merlin engines. After ignition, a hold-before-release system ensures that all engines are verified for full-thrust performance before the rocket is released for flight. Then, with thrust greater than five 747s at full power, the Merlin engines launch the rocket to space. Unlike airplanes, a rocket's thrust actually increases with altitude. Falcon 9 generates 1.3 million pounds of thrust at sea level but gets up to 1.5 million pounds of thrust in the vacuum of space. The first stage engines are gradually throttled near the end of first-stage flight to limit launch vehicle acceleration as the rocket’s mass decreases with the burning of fuel. Interstage The interstage, which connects the first and second stages, is a composite structure made of sheets of carbon fiber and an aluminum honeycomb core, and it holds the release and separation system. Falcon 9 uses 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. Second Stage The second stage, powered by a single Merlin vacuum engine, delivers Falcon 9’s payload to the desired orbit. The second stage engine ignites a few seconds after stage separation, and can be restarted multiple times to place multiple payloads into different orbits. Like the first stage, the second stage is made from a high-strength aluminum-lithium alloy, using most of the same tooling, materials, and manufacturing techniques. This commonality yields significant design and manufacturing efficiencies. Merlin 1D Engine The Merlin engine that powers the first stage of Falcon 9 is developed and manufactured in-house by SpaceX . Burning liquid oxygen and rocket-grade kerosene propellant, a single Merlin engine generates 654 kilonewtons (147,000 pounds) of thrust at liftoff, rising to 716 kilonewtons (161,000 pounds) as it climbs out of Earth’s atmosphere. Merlin’s thrust-to-weight ratio exceeds 150, making the Merlin the most efficient booster engine ever built, while still maintaining the structural and thermal safety margins needed to carry astronauts. Falcon 9 is the only vehicle currently flying with engine out capability. The nine-engine architecture on the first stage is an improved version of the design employed by the Saturn I and Saturn V rockets of the Apollo program, which had flawless flight records in spite of engine losses. 8 The Merlin 1D engine provides a number of improvements over its Merlin 1C predecessor, including greater performance, improved manufacturability by using high efficiency processes, increased robotic construction and reduced parts count. High-pressure liquid oxygen and kerosene propellant are fed to each engine via a single-shaft, dual-impeller turbopump operating on a gas generator cycle. Kerosene from the turbopump also serves as the hydraulic fluid for the thrust vector control actuators on each engine, and is then recycled into the low-pressure inlet. This design eliminates the need for a separate hydraulic power system, and eliminates the risk of hydraulic fluid depletion. Kerosene is also used for regenerative cooling of the thrust chamber and expansion nozzle. Octaweb The Octaweb thrust structure of the nine Merlin engines improves upon the former 3x3 engine arrangement, increasing the Falcon 9’s reliability while streamlining its manufacturing process. It houses the nine Merlin 1D engines and was designed to handle the increase in thrust from the Merlin 1C to Merlin 1D engine design. To form the structure, sheet metal is welded together and engines are placed into the nine slots. The eight engines surrounding one center engine simplify the design and assembly of the engine section, reducing production time from about three months to a matter of weeks. The new layout also provides individual protection for each engine, and further protects other engines in case of an engine failure. It significantly reduces both the length and weight of the Falcon 9 first stage. With this design, Falcon 9 is also prepared for reusability – the Octaweb will be able to survive the first stage’s return to Earth post-launch. Reliability This flight represents the eighth flight of the Falcon 9, following seven successful missions. An analysis of launch failure history between 1980 and 1999 by the Aerospace Corporation showed that 91% of known failures can be attributed to three causes: engine failure, stage-separation failure, and, to a much lesser degree, avionics failure. Because Falcon has nine Merlin engines clustered together to power the first stage, the vehicle is capable of sustaining certain engine failures and still completing its mission. This is an improved version of the architecture employed by the Saturn I and Saturn V rockets of the Apollo program, which had flawless flight records despite the loss of engines on a number of missions. With only two stages, Falcon 9 limits problems associated with separation events. SpaceX maximizes design and in-house production of much of Falcon 9’s avionics, helping ensure compatibility among the rocket engines, propellant tanks, and electronics. In addition, SpaceX has a complete hardware simulator of the avionics in its Hawthorne factory. This simulator, utilizing electronics identical to those on the rocket, allows SpaceX to check nominal and off-nominal flight sequences and validate the data that will be used to guide the rocket. SpaceX uses a hold-before-release system—a capability required by commercial airplanes, but not implemented on many launch vehicles. After the first-stage engines ignite, Falcon 9 is held down and not released for flight until all propulsion and vehicle systems are confirmed to be operating normally. An automatic safe shutdown occurs and propellant is unloaded if any issues are detected. 9 SpaceX Fairing The payload fairing sits atop Falcon 9 for the delivery of satellites to destinations in low-Earth orbit (LEO), geosynchronous transfer orbit (GTO) and beyond. SpaceX designed and developed its 5-meter fairing and manufactures every unit in Hawthorne, Calif. With an all- pneumatic deployment system (like Falcon 9’s interstage), the fairing experiences low shock and can be tested on the ground. The fairing is a composite structure made of sheets of carbon fiber and an aluminum honeycomb core. Large enough to carry a city bus, the fairing stands 17’ in diameter and 43’ tall and is designed to reliably meet all mission requirements. There are two halves to the fairing. One side is passive, and one is active with all actively controlled systems. Structurally, the lower joint connects the fairing to the payload attach fitting and the 2nd stage. There is a vertical seam connecting the two fairing halves. The same latch mechanism is used in 14 locations along the vertical seam. Four pushers that share similar design components with the stage separation system separate the fairing halves at deployment. Falcon 9 uses 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.
