RS1 is a two-stage orbital expendable launch vehicle designed and manufactured by ABL Space Systems in El Segundo, California. As of January 2022, its inaugural flight is planned for mid-2022[1] from the Pacific Spaceport Complex's Launchpad 3C[2] on Kodiak Island, Alaska. As of October 2021, over 75 RS1 launches have been booked[3], with notable planned payloads including prototypes for Amazon's Project Kuiper[4], NASA's Cryogenic Demonstration Mission[5], and Lockheed Martin's UK Pathfinder mission.[6]

Description[edit]
RS1 is a two-stage launch vehicle. The vehicle and its supporting ground systems, marketed by ABL as GS0, are designed to entirely fit within containers to facilitate rapid deployment nearly anywhere in the world.[7] Both of RS1's stages are powered by E2 engines burning kerosene and oxygen propellants in a gas-generator cycle. Notably, ABL claims RS1 is capable of using any of rocket-grade kerosene (RP-1), aviation-grade kerosene (Jet-A), and methane.[7] The first stage uses nine E2 engines arranged in a ring. Each engine produces 14,790 lbf (65 kN) of thrust, for a total of 133,118 lbf (598 kN).[8] The second stage uses a single, vacuum-optimized E2 producing 13,000 lbf (58 kN) of thrust.
RS1's standard payload fairing is 80 inches (2 meters) in diameter with 186" (4.73 m) of usable height. An "XL" 108" (2.7 m) fairing is also available.[8] ABL states that the rocket is capable of launching up to 1,350 kg (2,975 lb) to low Earth orbit, or 970 kg (2,140 lb) to a sun-synchronous orbit.
Launches[edit]
ABL is currently targeting mid-2022 for RS1's inaugural flight[1] from the Pacific Spaceport Complex's Launchpad 3C[2] on Kodiak Island, Alaska. The flight, referred to within FCC filings as "Demo-1," will carry two 6U CubeSats for OmniTeq to a 200 x 350 km orbit.[9]
At least 75 other flights are planned for RS1, including at minimum 26 and at maximum 58 purchased by Lockheed Martin.[3][10]
