NASA Conducts RS-25 Engine Test in Support of Future Artemis Missions

Preparations for Next Moonwalk Simulations Underway (and Underwater)

NASA tested RS-25 engine No. 10001 on Oct. 21 on the Fred Haise Test Stand at NASA’s Stennis Space Center near Bay St. Louis, Mississippi.

Test teams fired the developmental engine for almost eight-and-a-half minutes (500 seconds), the same amount of time RS-25 engines fire during launch of NASA’s SLS (Space Launch System) rocket.

During the test, operators also fired the engine up to the 111% power level, matching the thrust needed for new production engines to launch the SLS rocket and the Orion spacecraft to orbit.

The main objectives of the test were to acceptance test RS-25 flight components for future Artemis missions and validate the new thermal protection system, which protects the RS-25 engine nozzle from the thermal environment surrounding SLS during launch.

While this developmental engine will not be used in flight, the hot fire test provides NASA and NASA’s prime contractor L3Harris Technologies with the capability to capture critical data to improve engine performance and reliability.

Four RS-25 engines produce up to 2 million pounds of combined thrust to help launch the SLS rocket for each Artemis mission.

All RS-25 engines are tested and proven flightworthy at NASA Stennis prior to use. Tests are conducted by a team of operators from NASA, L3Harris, and Nova Space Solutions.

Interstellar probes. Lunar drones. Helicopters on Mars.

When a group of Caltech graduate students and enthusiasts began conducting rocket-propulsion tests in Pasadena’s Arroyo Seco on Oct. 31, 1936, they had no idea that their work marked the inception of the Jet Propulsion Laboratory. Ninety years later, the lab, now managed by Caltech for NASA, isn’t only celebrating the long line of historic firsts accomplished here; it’s paving the way for many to come.

Initially a contractor for the U.S. Army, JPL launched America’s first satellite, Explorer 1 in 1958. But rather than just orbiting Earth like the Soviet Union’s Sputnik, Explorer 1 became the first spacecraft to conduct science, thanks to an onboard Geiger counter that discovered the protective radiation belts encircling Earth.

The lab joined part of the newly formed NASA that same year. Within six years, in 1964, JPL sent the first U.S. mission to the Moon, Ranger 7. It also went on to lead the first planetary flyby, the first probe to visit all four gas giants, the first infrared telescope, the first rovers to roll on Mars, and the first rotorcraft to fly there, among many other historic milestones.

More firsts are on the way.

“Over the course of 90 years, JPL’s first-of-a-kind missions have transformed our understanding of the universe and our place in it,” said Dave Gallagher, JPL’s director since 2025. In 1992, only a couple years after he started as an engineer at the lab, Gallagher led the JPL team that built and tested the Wide-Field and Planetary 2 Camera for NASA’s Hubble Space Telescope, which delivered many of the mission’s most iconic images. “We stand on an extraordinary foundation, and we’re ready to push the boundaries with exciting new missions so that future generations can go even further.”

Aiming for a 2028 launch, the JPL-managed SkyFall mission will deploy three helicopters mid-descent over Mars to search to map hidden ice deposits and analyze weather patterns. Helping advance NASA’s Moon Base, JPL is developing MoonFall, a mission that will land a group of large propulsive drones at the lunar South Pole that same year. Set for a 2027 launch, SunRISE (Sun Radio Interferometer Space Experiment) features six toaster-oven-size satellites that will fly in formation to create a miles-wide radio antenna dish in order to study the Sun’s activity. What it reveals could help make space exploration safer for humans.

Protecting humanity is also the goal of the asteroid-hunting NEO Surveyor (Near-Earth Object Surveyor) mission, which, managed by JPL, will hunt for potentially hazardous space rocks that other telescopes can’t find. Once an object is spotted, NASA can offer a threat assessment and plan accordingly.

Closer to home, the same lab that launched the first oceanographic satellite in 1978 is at work on several missions that will offer a deeper reading of Earth’s vital signs. Where one mission will monitor the movement of water by measuring slight changes in gravity, another will study how powerful tropical convective storms form. A third will detail how different types of air pollution affect human health.

They add to a fleet of other Earth missions and projects JPL helps lead, including NISAR (NASA-ISRO Synthetic Aperture Radar) a joint mission with the Indian Space Research Organisation that can pinpoint how Earth’s surface changes in relation to natural disasters. Another, one of a series of instruments called AVIRIS (Airborne Visible Infrared Imaging Spectrometer), can even detect rare Earth elements critical to modern technology.

Flown on airplanes, the AVIRIS sensors were developed at JPL’s Microdevices Laboratory, which invented the “camera on a chip” technology that enables cellphones to take pictures. It’s also where the detectors are being developed for PRIMA (PRobe far-Infrared Mission for Astrophysics), a newly announced NASA mission that will strengthen humanity’s understanding of the universe by studying radiant energy visible only in the far-infrared. 

“Bringing together the very best of scientific brilliance and engineering ingenuity from across Caltech and JPL continues to advance NASA’s priorities and empower America’s space leadership,” said Caltech’s president Ray Jayawardhana, who is also a professor of astronomy. “I can only imagine what those Caltech students experimenting with rockets in a little patch of dry riverbed would think if they could to see what Caltech and JPL have accomplished since, and where we’re headed next. Ninety years later, the same spirit of daring is still opening new frontiers and inspiring humanity.”

The 90th anniversary comes just a few weeks before another milestone, when on Nov. 18 Voyager 1 reaches a full light-day — the distance light will travel in 24 hours, which is some 16 billion miles, or 26 billion kilometers — from Earth. Ed Stone led the mission for 50 years, serving as JPL’s director for 10 of them. Stone died in 2024, but the Voyagers are continuing on their journey deeper into interstellar space, a place no other spacecraft have ventured. Turning 50 next year, they rely on NASA’s Deep Space Network (developed by JPL in the Apollo era) to receive commands and send back science data. Stone said that with both Voyagers exploring regions never before visited, “every day is a day of discovery.” The same could be said for JPL.

Tracks Along the Longest Drive on Another World

2026-10-21 15:50

A wide view of the Martian surface taken by the Perseverance rover. The foreground features an arid, tan-colored terrain scattered with rocks and pebbles of varying sizes. Faint, parallel rover tracks curve through the dirt from the middle-left towards a shallow sandy depression in the midground. A distinct, slightly larger rock sits near the tracks on the far left. The background consists of smooth, gently rolling hills and distant ridges that fade into a hazy, pale yellow-brown sky.
This image, taken by Perseverance on Mars, shows wheel tracks from the drive that broke the record for the farthest distance driven on another celestial body. The image was acquired with its Left Navigation Camera on Oct. 11, 2026 (Sol 2006) at a local mean solar time of 14:40:39.
NASA/JPL-Caltech

Written by Vandi Verma, Chief Engineer for Robotic Operations at NASA’s Jet Propulsion Laboratory

Oct. 12, 2026

Since the last blog update, Perseverance has achieved a major milestone on Mars. On Sol 2006 (Oct. 11, 2026), its odometer reached 45.22 kilometers (28.10 miles), setting a new record for the farthest distance driven on another celestial body. Its engineering twin here on Earth even received a plaque from Guinness World Records celebrating the achievement. 

Two months ago, on Sol 1947, the odometer sat about 200 meters away from the milestone, a distance easily achievable with a single drive using Autonomous Navigation (AutoNav). However, the rover found itself in a very scientifically interesting area and spent time executing short drives to perform rock abrasions and proximity science on ancient rock outcrops. When Perseverance was finally ready to move on to a new site, it sailed past the record. 

On its way to the drive record, Perseverance has navigated challenging terrain while also pioneering new ways to drive across the Martian surface. Perseverance’s various encounters with dense boulder fields and steep slopes have pushed the team to re-evaluate driving guidelines so the rover is better prepared to handle tough terrain. After running thousands of simulations, the team raised the rover’s tilt limit to 24 degrees and reduced the clearance required under the rover’s belly pan to 20 centimeters (about 7.9 inches). The team also updated the rover’s braking software to avoid rock hazards, nearly doubled steer motor current limits, updated flight software with “dynamic slip tables” to model expected slip, and used cross-slope driving to better anchor wheels on exposed bedrock.  

One of the most exciting updates the team has made is an autonomous drive capability called onboard Global Localization (GBLC). GBLC repurposes the high-speed commercial processor inside the Ingenuity Helicopter Base Station to compare ground and orbital imagery to autonomously locate the rover in global coordinates at the end of a drive (as though we had GPS on a world without it), enabling Perseverance to drive longer distances without human intervention. Unlike Perseverance’s main flight computer, this coprocessor is not hardened against the punishing radiation environment of the Martian surface, where a thin atmosphere and the lack of a global magnetosphere leave little shielding. This radiation can induce “transient bit flips” in memory the software needs to function, and the team developed an effective software-based approach to radiation hardening. Looking forward to the greater demands of longer drives and to planning more activity with fewer resources, the team is also exploring the use of generative SI to help efficiently propose solutions to steer AutoNav along the many legs of a strategic path.  

The team is using hard-won lessons from 45 kilometers (more than 28 miles) of driving to reinvent how the rover drives across the Martian surface. As Perseverance climbs higher along the crater rim, the next leap in autonomous exploration on Mars is just getting started.
