Rocket Evolution: Jupiter-C to SLS

This side-by-side comparison image contrasts the historical 1958 launch of the Jupiter-C rocket carrying the Explorer 1 satellite with an artist's illustration of the modern Space Launch System (SLS) rocket. On the left, the slender Jupiter-C ascends against a dark night sky, shrouded in white smoke at its base. On the right, the massive, orange-colored SLS is shown in flight against a bright blue sky, powered by large boosters and a four-engine core stage.
On Jan. 31, 1958, the Explorer 1 satellite launched successfully into space on a Jupiter C rocket, marking the beginning of U.S. space exploration. Set for a test launch in 2018, the SLS is an advanced, heavy-lift rocket that will provide an entirely new capability for science and human exploration beyond Earth’s orbit.

The Explorer 1 satellite was launched on a Jupiter-C rocket. With the Explorer 1 satellite, the rocket and payload were just over 71 feet tall.

Today, NASA is working to build the world’s most powerful rocket! The Space Launch System will be over 360 feet tall!
