Please answer the following question: Information: - The Soviet RD - 0120 ( also designated 11D122 ) was the Energia core rocket engine , fueled by LH2 / LOX , roughly equivalent to the Space Shuttle Main Engine ( SSME ) . These were attached to the Energia core rather than the orbiter , so were not recoverable after a flight , but created a more modular design ( the Energia core could be used for a variety of missions besides launching the shuttle ) . Baselined from the more mature American hydrogen -- oxygen engine technology , but considerably modified with Russian innovations and methods , the RD - 0120 and the SSME have both similarities and differences . The RD - 0120 achieved nearly identical specific impulse and combustion chamber pressure with reduced complexity and cost , as compared to the SSME , primarily at the expense of lower thrust - to - weight ratio . It uses fuel - rich staged combustion cycle and a single shaft to drive both the fuel and oxidizer turbopumps . Some of the Russian design features , such as the simpler and cheaper channel wall nozzles , were evaluated by Rocketdyne for possible upgrades to the SSME . It achieved combustion stability without the acoustic resonance chambers that the SSME required . - The Aerojet Rocketdyne RS-25, otherwise known as the Space Shuttle main engine (SSME), is a liquid-fuel cryogenic rocket engine that was used on NASA's Space Shuttle and is planned to be used on its successor, the Space Launch System. Built in the United States by Rocketdyne, the RS-25 burns cryogenic liquid hydrogen and liquid oxygen propellants, with each engine producing of thrust at liftoff. Although the RS-25 can trace its heritage back to the 1960s, concerted development of the engine began in the 1970s, with the first flight, STS-1, occurring on April 12, 1981. The RS-25 has undergone several upgrades over its operational history to improve the engine's reliability, safety and maintenance load. - The tomato (see pronunciation) is the edible fruit of "Solanum lycopersicum", commonly known as a tomato plant, which belongs to the nightshade family, "Solanaceae". The species originated in Central and South America. The Nahuatl (Aztec language) word "tomatl" gave rise to the Spanish word "tomate", from which the English word tomato originates. Numerous varieties of tomato are widely grown in temperate climates across the world, with greenhouses allowing its production throughout the year and in cooler areas. The plants typically grow to in height and have a weak stem that often sprawls over the ground and vines over other plants. It is a perennial in its native habitat, and grown as an annual in temperate climates. An average common tomato weighs approximately . Its use as a food originated in Mexico, and spread throughout the world following the Spanish colonization of the Americas. Tomato is consumed in diverse ways, including raw, as an ingredient in many dishes, sauces, salads, and drinks. While tomatoes are botanically berry-type fruits, they are considered culinary vegetables, being ingredients of savory meals. - The San Fernando Valley is an urbanized valley located in Los Angeles County, California, defined by the mountains of the Transverse Ranges circling it. Home to 1.8 million people, it lies north of the larger and more populous Los Angeles Basin. - A bagel ('), also spelled beigel, is a bread product originating in the Jewish communities of Poland. It is traditionally shaped by hand into the form of a ring from yeasted wheat dough, roughly hand-sized, that is first boiled for a short time in water and then baked. The result is a dense, chewy, doughy interior with a browned and sometimes crisp exterior. Bagels are often topped with seeds baked on the outer crust, with the traditional ones being poppy, sunflower or sesame seeds. Some may have salt sprinkled on their surface, and there are different dough types, such as whole-grain or rye. - The RD-170 (-170, -170, Rocket Engine-170) is the world's most powerful liquid-fuel rocket engine, designed and produced in the Soviet Union by NPO Energomash for use with the Energia launch vehicle. The engine burns the Russian equivalent of RP-1 fuel and LOX oxidizer in four combustion chambers, all supplied by one single-shaft, single-turbine turbo pump rated at 170 MW in a staged combustion cycle. - Lox is a fillet of brined salmon. Traditionally, lox is served on a bagel with cream cheese, and is usually garnished with tomato, sliced red onion, and sometimes capers. - California is the most populous state in the United States and the third most extensive by area. Located on the western (Pacific Ocean) coast of the U.S., California is bordered by the other U.S. states of Oregon, Nevada, and Arizona and shares an international border with the Mexican state of Baja California. The state capital is Sacramento. Los Angeles is California's most populous city, and the country's second largest after New York City. The state also has the nation's most populous county, Los Angeles County, and its largest county by area, San Bernardino County. - Energia (, "Energy") was a Soviet rocket that was designed by NPO Energia to serve as a heavy-lift expendable launch system as well as a booster for the Buran spacecraft. Control system main developer enterprise was the NPO "Electropribor". The Energia used four strap-on boosters each powered by a four-chamber RD-170 engine burning kerosene/LOX, and a central core stage with 4 one-chamber RD-0120 (11D122) engines fueled by liquid hydrogen/LOX. - Rocketdyne was an American rocket engine design and production company headquartered in Canoga Park, located in the western San Fernando Valley of suburban Los Angeles, in southern California. - Kerosene, also known as paraffin, lamp oil and coal oil (an obsolete term), is a combustible hydrocarbon liquid which is derived from petroleum, widely used as a fuel in industry as well as households. Its name derives from ("keros") meaning wax, and was registered as a trademark by Abraham Gesner in 1854 before evolving into a genericized trademark. It is sometimes spelled kerosine in scientific and industrial usage. The term kerosene is common in much of India, Canada, the United States, Argentina, Australia and New Zealand and the term paraffin is used in the United Kingdom, Southeast Asia, East Africa and South Africa. Liquid paraffin (called mineral oil in the US) is a more viscous and highly refined product which is used as a laxative. Paraffin wax is a waxy solid extracted from petroleum. - The National Aeronautics and Space Administration (NASA ) is an independent agency of the executive branch of the United States federal government responsible for the civilian space program as well as aeronautics and aerospace research.
