Rocket engines vary widely in their propellants, efficiency and thrust levels. The reasons for the variations stem from what the engine is supposed to do. In this assignment, we'll look at two very different engines, and compare/contrast them. The RS-68 is a large, high-thrust engine, while the RL10 is a small, low-thrust engine. These engines have similarities and differences. Let's say you are a technical advisor to an administrator who is relying on you for a concise and complete assessment of the two engines, Using Hunt Library. B. the Web, and other resources, prepare a technical summary of the two engines. Explain their basic characteristics, as well as how and why they differ. The summary should look like a briefing to a busy administrator who has about ten minutes to comprehend the material. You can do it in written form, as bullet points, or as a combination of the two
