Bread dough rising or cryogenic test tank? 🤔 ⁣ ⁣ As we establish a long-term presence on and around the Moon with #Artemis, we are developing new technologies to overcome the challenges that await future astronauts. ⁣ ⁣ Spacecraft propulsion and life support systems rely on cryogenic fluids, meaning fluids that exist in a liquid state in extremely cold temperatures, such as liquid hydrogen, methane, and oxygen. For a cryogenic fluid to be useable, it must remain in a frigid, liquid state. However, the physics of space travel – moving in and out of sunlight and long stays in low gravity – complicate that process. ⁣ ⁣ Engineers working in NASA’s Cryogenic Fluid Management portfolio are solving those issues ahead of future missions. These solutions include Radio Frequency Mass Gauges to allow for more accurate fluid measurement in low-gravity conditions. Teams are also testing high-capacity cryocooler systems that pump fluid through a network of tubes to keep it cool. NASA is also dev...
