👉 The oxygen fluid, often referred to as liquid oxygen (LOX), is a cryogenic liquid composed primarily of molecular oxygen (O₂) with small amounts of nitrogen (N₂). It is stored at extremely low temperatures, typically around -183°C (-297°F), to maintain its liquid state. This fluid is crucial in various applications, particularly in rocket propulsion systems, where it serves as an oxidizer. When combined with a fuel like liquid hydrogen, it enables efficient and powerful thrust by supporting combustion. The high energy density and clean combustion properties of oxygen fluid make it an essential component in aerospace engineering, facilitating the launch and maneuvering of spacecraft.
