NASA Engineers Test Engine for World’s Most Powerful Rocket

NASA engineers tested the RS-25 rocket engine, which will play a crucial role in eventual missions to Mars, on Tuesday . . .

The forthcoming Space Launch System (SLS) rocket will be powered by four R2-25 engines firing simultaneously. The RS-25s will provide 2 million pounds of thrust, according to NASA and will work in conjunction with a pair of solid rocket boosters, which provide an additional 6.8 million pounds of thrust.

The first unmanned flight of the heavy-lift SLS – a trip around the moon – was scheduled for 2018, but was recently pushed back to 2019, Space.com reports. A crewed mission was expected to take place in 2021, but it has also been pushed back. NASA said there will be a minimum of 33 months between the unmanned and crewed missions.
