How Big Is NASA’s SLS Moon Rocket?
NASA’s Space Launch System (SLS) rocket stands 322 feet (98 meters) tall—roughly the length of an American football field from end zone to end zone . To put that height in perspective, the rocket towers over the 305-foot Statue of Liberty by 17 feet .
At liftoff, the fully fueled SLS weighs approximately 5.75 million pounds and generates a staggering 8.8 million pounds of thrust—about 15% more power than the Saturn V rockets that carried Apollo astronauts to the Moon .
Breaking Down the Rocket
The SLS is composed of several massive components:
The core stage alone holds 733,000 gallons of super-cold liquid hydrogen and liquid oxygen, chilled to minus 423°F .
How SLS Compares to Other Rockets
While the SLS is among the largest rockets ever built, it is not the tallest—that title belongs to SpaceX’s Starship, which stands approximately 403 feet when fully stacked .
Why Size Matters
The SLS is classified as a super-heavy lift launch vehicle and is the only rocket currently capable of sending NASA’s Orion capsule—with up to four astronauts and large cargo—directly to the Moon on a single mission .
The Artemis II mission, targeted for launch as early as April 1, 2026, will carry NASA astronauts Reid Wiseman, Victor Glover, Christina Koch, and Canadian Space Agency astronaut Jeremy Hansen on a 10-day journey around the Moon.
