RS-25 engines powering NASA's SLS (Space Launch System) rocket use liquid oxygen and liquid hydrogen as propellants – the same elements that combine to create water (H2O). For an RS-25 engine test, liquid hydrogen and liquid oxygen are mixed in the engine combustion chamber and ignited, which results in extremely high-temperature exhaust (up to 6,000 degrees F) exiting the nozzle into the flame deflector at a very high rate and pressure. Hundreds of thousands of gallons of water also are flowing

Meet Ms Doris Toh. She and her colleagues are using AI to level-up their teaching practices using the ✨Student Learning Space (SLS)✨, which has AI features with safety guardrails such as: 🤖 Data Assistant: Uses natural language to prompt for summaries of students’ responses, or ask the AI to highlight common misconceptions, and much more. 🧑‍✈️Authoring Copilot: Generates lesson ideas, activities, and quiz questions using large language models trained on MOE curriculum. Together with Ms Tan Yi

Have you tried the updated features in the Singapore Student Learning Space (SLS)? Met Kairos from Peicai Secondary, and he gamely showed me five ways he uses SLS for his own learning. Now in SLS, you can schedule new tasks to master, search for cool lessons and check your strengths and weaknesses! The MOE library is worth exploring, with topics outside of the school syllabus, if you're curious to learn more. New school year, new ways to self-study 😊 Happy learning! #ourschoolstories #learnwith
