Water vapor poured across the Mississippi landscape as NASA's ground-tested engine type that can bring an astronaut to the moon in the next three years.
The agency fired its RS-25 engine at 3:35 pm. EDT (2:25 pm local time CETT or 1935 GMT) today (Thursday) at NASA's John C. Stenn Space Center, near the Mississippi-Louisiana border.
The test is part of a larger effort to get the massive Space Launch System (SLS) megarocket is ready to bring the astronaut to the moon in the 2020s for the Lunar Gateway space station, culminating in a possible landing on the moon in 2024 if the Trump administration's wishes are carried out in time.

Last week, NASA Administrator Jim Bridenstine said his teams would speed up their SLS work schedule to meet the new moon-landing deadline . However, NASA's recent budget request for 2020 is still under construction.
In late March, NASA and Boeing (the SLS prime contractor) announced they have almost This completed flight, called Exploration Mission-1, will be a test that will send a Orion spacecraft around the moon and then back to earth again. The first crew is scheduled to fly to Orion in 2022.
RS-25 is best known for powering the space shuttle, which flew 135 missions between 1981 and 2011 before the fleet was retired. Putting four of the compact-car-size engines together at the core stage of SLS provides 2 million lbs. of thrust, officials at Stennis said in a Facebook post. Booster stages attached to the core provide the rest of the required 8.8 million lbs. of maximum thrust to send SLS to orbit.
NASA no longer uses the space shuttle to send an American astronaut to orbit; For now, all of its astronauts fly on Russian Soyuz rockets to the International Space Station – until commercial crew vehicles are ready for test flights in 2019 and 2020. NASA plans to continue to put some astronaut on Soyuz even after regular Commercial crew missions in SpaceX Dragon and Boeing CST-100 Starliner vehicles begin.
Stennis is a busy location for NASA rocket engine testing. Some of its past prominent work includes testing all the Saturn V engines and stages that were used for the Apollo program between the 1960s and 1970s, which landed 12 people on the moon between 1969 and 1972. (This July marks The 50th anniversary of the first moon landing.) Space Shuttle main engine testing also took place at Stennis between 1975 and 2009.
