Space Launch System

Combining power and capability, NASA’s Space Launch System rocket is part of NASA’s backbone for deep space exploration and Artemis. SLS is the only rocket that can send Orion, astronauts, and cargo directly to the Moon in a single launch.

Reference Guide

The SLS Reference Guide is the go-to source for information on the SLS rocket’s initial Block 1 configuration for NASA’s early Artemis missions, including its design, capabilities, major components, and manufacturing, testing, assembly, and launch activities. These documents were initially prepared for Artemis I and Artemis II launch activities.

Liftoff! NASA’s Space Launch System carrying the Orion spacecraft lifts off the pad at Launch Complex 39B at the agency’s Kennedy Space Center in Florida at 1:47 a.m. EST on Nov. 16, 2022. The first in a series of increasingly complex missions, Artemis I will provide a foundation for human deep space exploration and demonstrate our commitment and capability to extend human presence to the Moon and beyond. The primary goal of Artemis I is to thoroughly test the integrated systems before crewed missions by operating the spacecraft in a deep space environment, testing Orion’s heat shield, and recovering the crew module after reentry, descent, and splashdown.

NASA’s SLS (Space Launch System) rocket’s ICPS (interim cryogenic propulsion stage), with its single RL10 engine, produces 24,750 pounds of thrust to provide in-space propulsion for the agency’s Artemis II and III missions, the first crewed missions under Artemis. Like the mega rocket’s core stage, the ICPS uses liquid hydrogen and liquid oxygen to power its RL10 engine, manufactured by Aerojet Rocketdyne, an L3Harris Technologies company. The ICPS is built by ULA (United Launch Alliance) and Boeing. In addition to providing in-space propulsion, the ICPS also contains avionics to fly the mission after core stage separation until NASA’s Orion spacecraft separates from the ICPS to venture to the Moon.

The core stage will help launch the first crewed flight of NASA’s SLS rocket for the agency’s Artemis II mission. The move marked the first time a fully assembled Moon rocket stage for a crewed mission has rolled out from NASA’s Michoud Assembly Facility in New Orleans since the Apollo Program, The core stage was moved onto the agency’s Pegasus barge, where it will be ferried to NASA’s Kennedy Space Center in Florida. The core stage for the SLS mega rocket is the largest stage NASA has ever produced. At 212 feet tall, the stage consists of five major elements, including two huge propellant tanks that collectively hold more than 733,000 gallons of super chilled liquid propellant to feed four RS-25 engines at its base. During launch and flight, the stage will operate for just over eight minutes, producing more than 2 million pounds of thrust to help send a crew of four astronauts inside NASA’s Orion spacecraft onward to the Moon. NASA is working to land the first woman, first person of color, and its first international partner astronaut on the Moon under Artemis. SLS is part of NASA’s backbone for deep space exploration, along with the Orion spacecraft and Gateway in orbit around the Moon and commercial human landing systems, next-generation space, next-generational spacesuits, and rovers on the lunar surface. SLS is the only rocket that can send Orion, astronauts, and supplies to the Moon in a single launch.
