NASA Conducts 1st Hot Fire of New RS-25 Certification Test Series

NASA conducted the first hot fire of a new RS-25 test series Oct. 17, beginning the final round of certification testing ahead of production of an updated set of the engines for the SLS (Space Launch System) rocket. The engines will help power future Artemis missions to the Moon and beyond.

A full duration test of the RS-25 certification engine was conducted at NASA's Stennis Space Center on October 17, 2023.

Operators fired the RS-25 engine for more than nine minutes (550 seconds), longer than the 500 seconds engines must fire during an actual mission, on the Fred Haise Test Stand at NASA’s Stennis Space Center, near Bay St. Louis, Mississippi. Operators also fired the engine up to the 111% power level needed during an SLS launch. The hot fire marked the first in a series of 12 tests scheduled to stretch into 2024. The tests are a key step for lead SLS engines contractor Aerojet Rocketdyne, an L3Harris Technologies company, to produce engines that will help power the SLS rocket, beginning with Artemis V.

The test series will collect data on the performance of several new key engine components, including a nozzle, hydraulic actuators, flex ducts, and turbopumps. The components match design features of those used during the initial certification test series completed at the south Mississippi site in June. Aerojet Rocketdyne is using advanced manufacturing techniques, such as 3D printing, to reduce the cost and time needed to build the new engines. Four RS-25 engines help power SLS at launch, including on its Artemis missions to the Moon.

Through Artemis, NASA is returning humans, including the first woman and the first person of color, to the Moon to explore the lunar surface and prepare for flights to Mars. SLS is the only rocket capable of sending the agency’s Orion spacecraft, astronauts, and supplies to the Moon in a single mission.

      NASA Science, Cargo Launches Aboard Northrop Grumman CRS-23
      By NASA
      A SpaceX Falcon 9 rocket carrying Northrop Grumman’s Cygnus XL spacecraft is launched on NASA’s Northrop Grumman Commercial Resupply Services 23 mission to the International Space Station on Sunday, Sept. 14, 2025.Credit: NASA NASA is sending more science, technology demonstrations, and crew supplies to the International Space Station following the successful launch of the agency’s Northrop Grumman Commercial Resupply Services 23 mission, or Northrop Grumman CRS-23.
      The company’s Cygnus XL spacecraft, carrying more than 11,000 pounds of cargo to the orbiting laboratory, lifted off at 6:11 p.m. EDT Sunday on a SpaceX Falcon 9 rocket from Space Launch Complex 40 at Cape Canaveral Space Force Station in Florida. This mission is the first flight of the larger, more cargo-capable version of the solar-powered spacecraft. 
      Cygnus XL is scheduled to be captured at 6:35 a.m. on Wednesday, Sept. 17, by the Canadarm2 robotic arm, which NASA astronaut Jonny Kim will operate with assistance from NASA astronaut Zena Cardman. Following capture, the spacecraft will be installed to the Unity module’s Earth-facing port for cargo unloading.
      The resupply mission is carrying dozens of research experiments that will be conducted during Expedition 73, including materials to produce semiconductor crystals in space and equipment to develop improvements for cryogenic fuel tanks. The spacecraft also will deliver a specialized UV light system to prevent the growth of microbe communities that form in water systems and supplies to produce pharmaceutical crystals that could treat cancer and other diseases.
      These are just a sample of the hundreds of scientific investigations conducted aboard the station in the areas of biology and biotechnology, Earth and space science, physical sciences, as well as technology development and demonstrations. For nearly 25 years, NASA has supported a continuous U.S. human presence aboard the orbiting laboratory, where astronauts have learned to live and work in space for extended periods of time. The space station is a springboard for developing a low Earth economy and NASA’s next great leaps in exploration, including Artemis missions to the Moon and American astronaut missions to Mars.
      NASA’s arrival, capture, and installation coverage are as follows (all times Eastern and subject to change based on real-time operations):
      Wednesday, Sept. 17
      5 a.m. – Arrival coverage begins on NASA+, Amazon Prime, and more.
      6:35 a.m. – Capture of Cygnus XL with the space station’s robotic arm.
      8 a.m. – Installation coverage begins on NASA+, Amazon Prime, and more.
      All coverage times are estimates and could be adjusted based on operations after launch. Follow the space station blog for the most up-to-date information.
      Cygnus XL is scheduled to remain at the orbiting laboratory until March 2026, before it departs and disposes of several thousand pounds of trash through its re-entry into Earth’s atmosphere, where it will harmlessly burn up. The spacecraft is named the S.S. William “Willie” C. McCool, in honor of the NASA astronaut who perished in 2003 during the space shuttle Columbia accident.

      Drag Prediction Workshop Series
      By NASA
      The Drag Prediction Workshop series is an extensive international effort to improve transonic aerodynamic predictions. This long-running collaborative effort seeks to mobilize the international aerospace community to improve the computational methods and tools to predict transonic aircraft performance, particularly drag.

      More details on the workshop can be found at the workshop website: https://www.aiaa-dpw.org

      NASA has a storied history with the workshop series from DPW-I (hosted in 2001) through the upcoming DPW-8, held in concert with Aeroelastic Prediction Workshop 4. In addition to code and methods improvements, the series also resulted in the NASA/Boeing Common Research Model (https://commonresearchmodel.larc.nasa.gov/), an open-access, commercially-relevant aircraft geometry. This geometry has been extensively tested in many facilities throughout the world and been the subject of multiple workshop series.

      NASA’s contributions to the upcoming DPW-8 and subsequent work will be highlighted on this page.
