I heard NASA has a rainmaking machine at NASA Stennis. Is that true?

RS-25 engines use liquid oxygen and liquid hydrogen as propellants. These are 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 into the flame deflector to cool the exhaust and protect the deflector. When the hot exhaust mixes with the water, it creates steam that rises into the atmosphere, forming a cloud that subsequently cools. Depending on the temperature and humidity at the time of the test, this cloud of steam may condense into water and fall in a very limited and localized area. The steam released during a test is water and does not pollute the atmosphere.
