NASA’s Pegasus barge delivers the SLS (Space Launch System) rocket’s core stage for the 2022 Artemis I mission to the turn basin at Kennedy Space Center in Florida in April 2021. Credits: NASA/Michael Downs Media are invited in late July to NASA’s Kennedy Space Center in Florida to see progress on the agency’s SLS (Space Launch System) Moon rocket as preparations continue for the Artemis II test flight around the Moon.
Participants joining the multi-day events will see the arrival and unloading of the 212-foot-tall SLS core stage at the center’s turn basin before it is transported to the nearby Vehicle Assembly Building. The stage will arrive on NASA’s Pegasus barge from the agency’s Michoud Assembly Facility in New Orleans, where it was manufactured and assembled.
Media also will see the twin pair of solid rocket boosters inside the Rotation, Processing, and Surge Facility at the spaceport, where NASA’s Exploration Ground Systems Program is processing the motor segments in preparation for rocket assembly. NASA and industry subject matter experts will be available to answer questions. At launch, the SLS rocket’s two solid rocket boosters and four RS-25 engines, located at the base of its core stage, will produce 8.8 million pounds of thrust to send the first crewed mission of the Artemis campaign around the Moon.
Media interested in participating must apply for credentials at:
https://media.ksc.nasa.gov
To receive credentials, international media must apply by Friday, June 28, and U.S. citizens must apply by Thursday, July 5.
Credentialed media will receive a confirmation email upon approval, along with additional information about the specific date for the activities when they are finalized. NASA’s media accreditation policy is available online. For questions about accreditation, please email ksc-media-accreditat@mail.nasa.gov. For other questions, please contact Kennedy’s newsroom at: 321-867-2468.
Para obtener información sobre cobertura en español en el Centro Espacial Kennedy o si desea solicitar entrevistas en español, comuníquese con Antonia Jaramillo o Messod Bendayan a: antonia.jaramillobotero@nasa.gov o messod.c.bendayan@nasa.gov.
The approximately 10-day Artemis II flight will test NASA’s SLS rocket, Orion spacecraft, and ground systems for the first time with astronauts and will pave the way for lunar surface missions, including landing the first woman, first person of color, and first international partner astronaut on the Moon.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
A sample of fabric burns inside an uncrewed Cygnus cargo craft during a previous Spacecraft Fire Safety Experiment investigation, Saffire-IV.Credit: NASA NASA recently concluded the final mission of its Spacecraft Fire Safety Experiment, or Saffire, putting a blazing end to an eight-year series of investigations that provided insights into fire’s behavior in space.
The final experiment, Saffire-VI, launched to the International Space Station in August 2023 and concluded its mission on Jan. 9, when the Northrop Grumman Cygnus spacecraft it was flying on safely burned up during planned re-entry into Earth’s atmosphere.
Dr. David Urban, principal investigator, and Dr. Gary Ruff, project manager at NASA’s Glenn Research Center in Cleveland, have led the Saffire project from Northeast Ohio since its initial spark in 2016. Throughout the experiment series, researchers gathered data NASA will use to enhance mission safety and inform future spacecraft and spacesuit designs.
“How big a fire does it take for things to get bad for a crew?” Urban said. “This kind of work is done for every other inhabited structure here on Earth – buildings, planes, trains, automobiles, mines, submarines, ships – but we hadn’t done this research for spacecraft until Saffire.”
Like previous Saffire experiments, Saffire-VI took place inside a unit on an uninhabited Cygnus spacecraft that had already departed from the space station, ensuring the safety of the orbiting laboratory and a more representative flight environment. However, this final iteration of the experiment was unique because of the higher oxygen concentration and lower pressure generated in the test unit to simulate the conditions within crewed spacecraft.

NASA ignited the final set of space fire experiments for Saffire-VI inside Northrop Grumman’s Cygnus cargo spacecraft at the end of the NG-19 resupply mission to the International Space Station. Saffire, or Spacecraft Fire Safety Experiment, was a series of six investigations that provided insights into how fires grow and spread in space. This research is especially important as it will inform future spacecraft designs bound for the Moon and Mars. Video credit: NASA During the 19 Saffire-VI experiment runs, the NASA team and counterparts at Northrop Grumman made various adjustments to air conditions. They then ignited a flame on materials such as plexiglass, cotton, Nomex, and Solid Inflammability Boundary at Low-Speed fabrics. A bead-lined wire inside the unit ignited the materials.
“The Saffire flow unit is a wind tunnel. We’re pushing air through it,” Ruff said. “Once test conditions are set, we run electrical current through a thin wire, and the materials ignite.”
Cameras inside allowed the team to observe the flame while remote sensors outside the Saffire flow unit collected data about what was happening in the Cygnus vehicle. The images and information were gathered in real-time before being sent to Earth for scientists to analyze.
“You’ve got a heat release rate and a rate of release of combustion products,” Ruff said. “You can take those as model input and predict what will happen in a vehicle.”
The next decade of exploration and science missions will see astronauts flying deeper into space and to locations that have yet to be explored. Though the Saffire experiments have been extinguished, NASA has learned valuable lessons and gathered mountains of data on fire behavior that will help the agency design safer spacecraft and accomplish its ambitious future missions.

NASA/Danny Nowlin Clouds of white vapor pile up at NASA’s Stennis Space Center in Bay St. Louis, Mississippi during a full-duration, 500-second hot fire of an RS-25 certification engine Jan. 17, 2024. This test series is critical for future flights of NASA’s SLS (Space Launch System) rocket in support of the Artemis campaign.
During the Jan. 17 test, operators followed a “test like you fly” approach, firing the engine for the same amount of time – almost eight-and-a-half minutes (500 seconds) – needed to launch SLS and at power levels ranging between 80% to 113%.

Data collected from the test series will be used to certify production of new RS-25 engines by lead contractor Aerojet Rocketdyne, an L3Harris Technologies company, to help power the SLS rocket on future Artemis missions to the Moon and beyond, beginning with Artemis V.
Teams are evaluating the performance of several new engine components, including a nozzle, hydraulic actuators, flex ducts, and turbopumps. The current series is the second and final series to certify production of the upgraded engines. NASA completed an initial 12-test certification series with the upgraded components in June 2023.
During the Jan. 17 test, operators followed a “test like you fly” approach, firing the engine for the same amount of time – almost eight-and-a-half minutes (500 seconds) – needed to launch SLS and at power levels ranging between 80% to 113%.
The Jan. 17 test comes three months after the current series began in October. During three tests last fall, operators fired the engine for durations from 500 to 650 seconds. The longest planned test of the series occurred on Nov. 29 when crews gimbaled, or steered, the engine during an almost 11-minute (650 seconds) hot fire. The gimbaling technique is used to control and stabilize SLS as it reaches orbit.
Each SLS flight is powered by four RS-25 engines, firing simultaneously during launch and ascent to generate over 2 million pounds of thrust.
The first four Artemis missions with SLS are using modified space shuttle main engines that can power up to 109% of their rated level. The newly produced RS-25 engines will power up to the 111% level to provide additional thrust. Testing to the 113% power level provides an added margin of operational safety.
With the completion of the test campaign in 2024, all systems are expected to be “go” for production of 24 new RS-25 engines for missions beginning with Artemis V.
Through Artemis, NASA will establish a long-term presence at the Moon for scientific exploration with commercial and international partners, learn how to live and work away from home, and prepare for future human exploration of Mars.
