## Caption

Let’s have look at what 150,000 gallons of liquid oxygen and 60,000 gallons of liquid hydrogen firing from an RS-25 engine looks like from three different vantage points. NASA’s countdown to deep space continued two days ago with a 535-second test of its Space Launch System (SLS) RS-25 rocket engine to collect engine performance data at NASA's Stennis Space Center near Bay St. Louis, Mississippi. SLS will launch astronauts in the #Orion spacecraft on missions to deep space and eventually on the journey to Mars. Operators on the A-1 Test Stand at Stennis are conducting the test series to qualify an all-new engine controller and put the upgraded former space shuttle main engines through the rigorous temperature and pressure conditions they will experience during a SLS mission.

One final test of this RS-25 developmental engine is planned in this series; testing of flight engines begins later this fall.

Happy space Saturday everybody!
