Artist rendering of the RS-25 engines powering the liftoff of the 70-metric-ton (77-ton) lift capacity configuration SLS from the pad.
This artist rendering highlights the four RS-25 engines and two solid rocket boosters that provide the power to launch NASA’s Space Launch System (SLS) rocket and send it to space. The concept depicts the firing of the RS-25 engines and boosters as the lift the rocket to space, producing more than 8 million pounds of thrust in a little over 8 minutes.
