2/28/2024 0 Comments Falcon 9 heavy launch![]() The second stage is capable of doing several burns, allowing the Falcon to put payloads in several different orbits. It contains a singular MVacD engine that produces 992 kN of thrust and an ISP of 348 seconds. The Falcon Heavy second stage is the same as the Falcon 9’s. However, as the Falcon first stage is able to propulsively land, three of the Merlin engines (E1, E5, and E9) contain TEA-TEB canisters to relight for the boost back, reentry, and landing burns. During static fire and launch the TEA-TEB is provided by the ground service equipment. The Merlin engines are ignited by triethylaluminum and triethylborane (TEA-TEB), which instantly burst into flames when mixed in the presence of oxygen. Due to the powerful nature of each engine, and the large amount of them, the Falcon Heavy first stage is able to lose several engines right off the pad, or up to two later in the flight, and be able to successfully place the payload into orbit. Each engine produces 845 kN of thrust at sea level, with a specific impulse (ISP) of 285 seconds, and 934 kN in a vacuum with an ISP of 313 seconds. Each engine uses an open gas generator cycle and runs on RP-1 and liquid oxygen (LOx). The Falcon Heavy first stage contains 27 Merlin 1D+ sea-level engines across three cores. The X-37B after its OTV-5 mission (Credit: USSF) What Is The Falcon Heavy? First Stage Further details on this mission are unknown. Additionally, this mission will deploy the FalconSat-8 - a small satellite developed by the United States Air Force Academy that will test various technologies and perform scientific investigations in orbit. However, it is known that this mission will carry NASA’s Seeds-2 mission, which will expose plant seeds to harsh radiation environments of a long spaceflight. The purpose of this spacecraft is highly uncertain due to the classified nature of the mission. An expendable service module is attached to the back of the vehicle to support these long orbital missions. The vehicle had a designed orbital life of 270 days, which has been shattered as OTV-6 spent 908 days in orbit. For work in orbit, the spacecraft has two gallium arsenide solar cells and additional lithium-ion batteries. The 8.92-meter-long and 4.55-meter-wide spacecraft stands 2.9 meters tall and has a max take-off mass of 4,990 kg. Following its mission in orbit, which usually lasts on the order of two-to-three years, the plane lands back at Vandenberg Space Force Base or at Edwards Space Force Base. On orbit, the spacecraft demonstrates a large number of new technologies and conducts scientific investigations demonstrating space awareness.Īs the mission name implies, the X-37B has launched a total of six times ahead of this mission - five times on the Atlas V 501 and once on the Falcon 9. This reusable spaceplane is derived from the earlier Boeing X-40 and has a similar aerodynamic design to the space shuttle’s orbiter. The X-37B is an uncrewed test vehicle designed and manufactured by Boeing and operated by the USSF. Following the launch, both side boosters will be recovered downrange and the center core will be expended. This flight will mark the seventh overall launch and fourth for this vehicle (Vehicle 2) and will be launched atop SpaceX’s Falcon Heavy. SpaceX will launch the X-37B space plane to a currently unknown orbit for the United States Space Force (USSF). Tune in live for questions and conversation!
