      On Feb. 22, 2024, Intuitive Machines’ Odysseus lunar lander captures a wide field of view image of Schomberger crater on the Moon approximately 125 miles (200 km) uprange from the intended landing site, at approximately about 6 miles (10 km) altitude. Credit: Intuitive Machines For the first time in more than 50 years, new NASA science instruments and technology demonstrations are operating on the Moon following the first successful delivery of the agency’s CLPS (Commercial Lunar Payload Services) initiative.
      Intuitive Machines’ Nova-C lander, called Odysseus, completed a seven-day journey to lunar orbit and executed procedures to softly land near Malapert A in the South Pole region of the Moon at 5:24 p.m. CST on Feb. 22. The lander is healthy, collecting solar power, and transmitting data back to the company’s mission control in Houston. The mission marks the first commercial uncrewed landing on the Moon.
      Carrying six NASA science research and technology demonstrations, among other customer payloads, all NASA science instruments completed transit checkouts en route to the Moon. A NASA precision landing technology demonstration also provided critical last-minute assistance to ensure a soft landing. As part of NASA’s Artemis campaign, the lunar delivery is in the region where NASA will send astronauts to search for water and other lunar resources later this decade.
      “For the first time in more than half a century, America returned to the Moon. Congratulations to Intuitive Machines for placing the lunar lander Odysseus carrying NASA scientific instruments to a place no person or machine has gone before, the lunar South Pole,” said NASA Administrator Bill Nelson. “This feat from Intuitive Machines, SpaceX, and NASA demonstrates the promise of American leadership in space and the power of commercial partnerships under NASA’s CLPS initiative. Further, this success opens the door for new voyages under Artemis to send astronauts to the Moon, then onward to Mars.” 
      During the journey to the Moon, NASA instruments measured the quantity of cryogenic engine fuel as it has been used, and while descending toward the lunar surface, teams collected data on plume-surface interactions and tested precision landing technologies.
      Odysseus’ surface operations are underway and expected to take place through Thursday, Feb. 29.
      New lunar science, technology
      NASA’s Navigation Doppler Lidar for Precise Velocity and Range Sensing (NDL) guidance system for descent and landing ultimately played a key role in aiding the successful landing. A few hours ahead of landing, Intuitive Machines encountered a sensor issue with their navigation system and leaned on NASA’s guidance system for an assist to precisely land. NASA’s instrument operates on the same principles of radar and uses pulses from a laser emitted through three optical telescopes. It measures speed, direction, and altitude with high precision during descent and touchdown.
      “We are thrilled to have NASA on the Moon again, and proud of the agency’s contribution to the successful landing with our NDL technology. Congratulations for completing this first lunar delivery for NASA, paving the way for a bright future for our CLPS initiative,” said Nicky Fox. “Some of the NASA science instruments on this mission will bring us insight on lunar plume interactions and conduct radio astronomy. The valiant efforts and innovation demonstrated by Intuitive Machines is exemplary and we are excited for the upcoming lunar deliveries that will follow this first mission.”  
      Now that they are on the lunar surface, NASA instruments will focus on investigating lunar surface interactions and radio astronomy. The Odysseus lander also carries a retroreflector array that will contribute to a network of location markers on the Moon for communication and navigation for future autonomous navigation technologies.
      Additional NASA hardware aboard the lander includes:
      Lunar Node 1 Navigation Demonstrator: A small, CubeSat-sized experiment that will demonstrate autonomous navigation that could be used by future landers, surface infrastructure, and astronauts, digitally confirming their positions on the Moon relative to other spacecraft, ground stations, or rovers on the move. Laser Retroreflector Array: A collection of eight retroreflectors that enable precision laser ranging, which is a measurement of the distance between the orbiting or landing spacecraft to the reflector on the lander. The array is a passive optical instrument and will function as a permanent location marker on the Moon for decades to come.    Radio Frequency Mass Gauge: A technology demonstration that measures the amount of propellant in spacecraft tanks in a low-gravity space environment. Using sensor technology, the gauge will measure the amount of cryogenic propellant in Nova-C’s fuel and oxidizer tanks, providing data that could help predict fuel usage on future missions.    Radio-wave Observations at the Lunar Surface of the Photoelectron Sheath: The instrument will observe the Moon’s surface environment in radio frequencies, to determine how natural and human-generated activity near the surface interacts with and could interfere with science conducted there. Stereo Cameras for Lunar Plume-Surface Studies: A suite of four tiny cameras to capture imagery showing how the Moon’s surface changes from interactions with the spacecraft’s engine plume during and after descent. NASA is committed to supporting its U.S. commercial vendors as they navigate the challenges of sending science and technology to the surface of the Moon.
      “In daring to confront one of humanity’s greatest challenges, Intuitive Machines created an entire lunar program that has ventured farther than any American mission to land on the Moon in over 50 years,” said Altemus. “This humbling moment reminds us that pursuing the extraordinary requires both boldness and resilience.”

      Preparations for Next Moonwalk Simulations Underway (and Underwater)
      NASA recently completed a series of tests to reduce risks prior to Phase 2 of its Quesst mission, which will test the ability of the X-59 experimental aircraft to make sonic booms quieter. Credits: NASA/Steve Parcel NASA’s X-59 experimental aircraft is unique – it’s designed to fly faster than the speed of sound, but without causing a loud sonic boom. To confirm the X-59’s ability to fly supersonic while only producing quiet sonic “thumps,” NASA needs to be able to record these sounds from the ground. The agency recently completed tests aimed at understanding equipment and procedures needed to make those recordings.
      NASA’s Carpet Determination In Entirety Measurements (CarpetDIEM) flights examined the quality and ruggedness of a new generation of ground recording systems, focusing on how to deploy the systems for X-59 testing, and retrieve the data they collect. In all, researchers set up 10 microphone stations over a 30-mile stretch of desert near NASA’s Armstrong Flight Research Center in Edwards, California.
      “We’re trying to answer questions like how many people does it take to go out and service these instruments on a daily basis, how to get the data back, how many vehicles are needed – all those sorts of things on how we operate,” said Forrest Carpenter, principal investigator for the third flight series, known as CarpetDIEM III. “We’re kind of learning how to dance now so that when we get to the big dance, we’re ready to go.”
      The X-59 itself is not yet flying, so using an F-15 and an F-18 from NASA Armstrong, the CarpetDIEM III testing involved 20 supersonic passes with speeds ranging from Mach 1.15 to Mach 1.4, at altitudes ranging from 40,000 to 53,000 feet. Three of the passes involved an F-18 conducting a special inverted dive maneuver to simulate a quiet sonic boom, with one getting as quiet as 67 perceived level decibels, a measure of the perceived noisiness of the jet for an observer on the ground.
      Aerospace engineer Larry Cliatt, Quesst Phase 2 sub-project manager and technical lead for the acoustic validation phase of the Quesst mission, sets up a ground recording system in the California desert. The Quesst mission recently completed testing of operations and equipment to be used in recording the sonic thumps of the X-59. The testing was the third phase of Carpet Determination in Entirety Measurements flights, called CarpetDIEM for short. An F-15 and an F-18 from NASA’s Armstrong Flight Research Center in Edwards, California, created sonic booms, both loud and soft, to verify the operations of ground recording systems spread out across 30 miles of open desert.NASA/Steve Freeman “We expect the X-59 sonic thump to be as low as about 75 perceived loudness decibels,” said Larry Cliatt, sub-project manager for the Quesst acoustic validation phase. “That is a lot quieter than the Concord, which was over 100 perceived loudness decibels.”
      In order to measure these very quiet sonic thumps, the ground recording systems used in the CarpetDIEM flights were calibrated to measure as low as about 50 perceived loudness decibels – the equivalent to being in the room with a running refrigerator.
      CarpetDIEM III also validated the use of Automatic Dependent Surveillance-Broadcast, an existing technology flown on all commercial aircraft and most private aircraft to report speed and position. This system triggers the ground recording systems to begin recording.
      “We can’t have 70 different people at every single instrumentation box,” Cliatt said. “We had to find a way to automate that process.”
      Dr. Forrest Carpenter, left, principal investigator for the third phase of CarpetDIEM, Carpet Determination in Entirety Measurements flights, monitors a test from one of the control rooms at NASA’s Armstrong Flight Research Center in Edwards, California. Next to Carpenter is Brian Strovers, chief engineer for Commercial Supersonic Technology. The third phase of CarpetDIEM tested logistics and upgraded ground recording systems in preparation for the acoustic validation phase of the Quesst mission.NASA/Steve Freeman The recording systems are designed to withstand the desert elements, the extreme heat of summer and the cold of winter, and to be resistant to damage from wildlife, such as chewing by rodents, coyotes, and foxes.
      “When we get to Phase 2 of the Quesst mission, we expect to be doing these recordings of sonic thumps for up to nine months,” Cliatt said. “We need to be able to have instrumentation and operations that can facilitate such a long deployment.”
      Another lesson learned – setup time for the recording stations was just under an hour, compared to the anticipated 2 1/2 hours. Given the performance of the systems, the team will assess whether they need to visit all the sites every day of Phase 2 testing.
      The team also learned about the coordination and documentation processes needed for such research, both with internal organizations, such as NASA Armstrong’s Environmental and Safety offices, and with outside parties including:
      The U.S. Bureau of Land Management, which gave approval to use public lands for the testing Law enforcement, which helped secure the test site The Federal Aviation Administration, which gave approval for NASA jets to fly outside the Edwards Air Force Base restricted airspace in order to conduct a portion of the CarpetDIEM tests To prepare for Quesst Phase 2, researchers expect to conduct practice sessions in 2024, incorporating all the lessons learned and best practices from all three phases of CarpetDIEM.

      Teams at NASA’s Stennis Space Center install a new RS-25 engine nozzle in early February in preparation for continued testing on the Fred Haise Test Stand. NASA is conducting a series of tests to certify production of new RS-25 engines for future (Space Launch System) missions, beginning with Artemis V.NASA/Danny Nowlin NASA will conduct an RS-25 hot fire Friday, Feb. 23, moving one step closer to production of new engines that will help power the agency’s SLS (Space Launch System) rocket on future Artemis missions to the Moon and beyond.
      Teams at NASA’s Stennis Space Center near Bay St. Louis, Mississippi, are set to begin the second half of a 12-test RS-25 certification series on the Fred Haise Test Stand, following installation of a second production nozzle on the engine.
      Teams at NASA’s Stennis Space Center install a new RS-25 engine nozzle in early February in preparation for continued testing on the Fred Haise Test Stand.

NASA is conducting a series of tests to certify production of new RS-25 engines for future (Space Launch System) missions, beginning with Artemis V.NASA/Danny Nowlin The six remaining hot fires are part of the second, and final, test series collecting data to certify an updated engine production process, using innovative manufacturing techniques, for lead engines contractor Aerojet Rocketdyne, an L3Harris Technologies company.
      As NASA aims to establish a long-term presence on the Moon for scientific discovery and exploration, and prepare for future missions to Mars, new engines will incorporate dozens of improvements to make production more efficient and affordable while maintaining high performance and reliability.
      Four RS-25 engines, along with a pair of solid rocket boosters,  launch NASA’s powerful SLS rocket, producing more than 8.8 million pounds of thrust at liftoff for Artemis  missions.
      During the seventh test of the 12-test series, operators plan to fire the certification engine for 550 seconds and up to a 113% power level.
      “NASA’s commitment to safety and ‘testing like you fly’ is on display as we plan to fire the engine beyond 500 seconds, which is the same amount of time the engines must fire to help launch the SLS rocket to space with astronauts aboard the Orion spacecraft,” said Chip Ellis, project manager for RS-25 testing at Stennis.
      The Feb. 23 test features a second certification engine nozzle to allow engineers to gather additional performance data on the upgraded unit. The new nozzle was installed on the engine earlier this month while it remained at the test stand. Using specially adapted procedures and tools, the teams were able to swap out the nozzles with the engine in place.
      Teams at NASA’s Stennis Space Center install a new RS-25 engine nozzle in early February in preparation for continued testing on the Fred Haise Test Stand. NASA is conducting a series of tests to certify production of new RS-25 engines for future (Space Launch System) missions, beginning with Artemis V.NASA/Danny Nowlin In early February 2024, teams at NASA’s Stennis Space Center near Bay St. Louis, Mississippi, completed an RS-25 nozzle remove-and-replace procedure as part of an ongoing hot fire series on the Fred Haise Test Stand. The new nozzle will allow engineers to collect and compare performance data on a second production unit. The RS-25 nozzle, which directs engine thrust, is the most labor-intensive component on the engine and the hardest to manufacture, said Shawn Buckley, Aerojet Rocketdyne’s RS-25 nozzle integrated product team lead.
      Aerojet Rocketdyne has focused on streamlining the nozzle production process. Between manufacture of the first and second production units, the company reduced hands-on labor by 17%.
      “The nozzle is a work of machinery and work of art at the same time,” Buckley said. “Our team sees this nozzle as more than a piece of hardware. We see the role we play in the big picture as we return humans to the Moon.”
      With completion of the certification test series, all systems will be “go” to produce the first new RS-25 engines since the space shuttle era. NASA has contracted with Aerojet Rocketdyne to produce 24 new RS-25 engines using the updated design for missions beginning with Artemis V. NASA and Aerojet Rocketdyne modified 16 former space shuttle missions for use on Artemis missions I through IV.
      Through Artemis, NASA will establish the foundation for long-term scientific exploration at the Moon, land the first woman, first person of color, and first international partner astronaut on the lunar surface, and prepare for human expeditions to Mars for the benefit of all.
