Landing on the Moon is not easy, particularly when a crew or spacecraft must meet exacting requirements. For Artemis missions to the lunar surface, those requirements include an ability to land within an area about as wide as a football field in any lighting condition amid tough terrain.
NASA’s official lunar landing requirement is to be able to land within 50 meters (164 feet) of the targeted site and developing precision tools and technologies is critically important to mission success.
NASA engineers recently took a major step toward safe and precise landings on the Moon – and eventually Mars and icy worlds – with a successful field test of hazard detection technology at NASA’s Kennedy Space Center Shuttle Landing Facility in Florida.
A joint team from the Aeroscience and Flight Mechanics Division at NASA’s Johnson Space Center’s in Houston and Goddard Space Flight Center in Greenbelt, Maryland, achieved this huge milestone in tests of the Goddard Hazard Detection Lidar from a helicopter at Kennedy in March 2025.
NASA’s Hazard Detection Lidar field test team at Kennedy Space Center’s Shuttle Landing Facility in Florida in March 2025. NASA The new lidar system is one of several sensors being developed as part of NASA’s Safe & Precise Landing – Integrated Capabilities Evolution (SPLICE) Program, a Johnson-managed cross-agency initiative under the Space Technology Mission Directorate to develop next-generation landing technologies for planetary exploration. SPLICE is an integrated descent and landing system composed of avionics, sensors, and algorithms that support specialized navigation, guidance, and image processing techniques. SPLICE is designed to enable landing in hard-to-reach and unknown areas that are of potentially high scientific interest.
The lidar system, which can map an area equivalent to two football fields in just two seconds, is a crucial program component. In real time and compensating for lander motion, it processes 15 million short pulses of laser light to quickly scan surfaces and create real-time, 3D maps of landing sites to support precision landing and hazard avoidance.
Those maps will be read by the SPLICE Descent and Landing Computer, a high-performance multicore computer processor unit that analyzes all SPLICE sensor data and determines the spacecraft’s velocity, altitude, and terrain hazards. It also computes the hazards and determines a safe landing location. The computer was developed by the Avionics Systems Division at Johnson as a platform to test navigation, guidance, and flight software. It previously flew on Blue Origin’s New Shepard booster rocket.
The NASA team prepares the Descent and Landing Computer for Hazard Detection Lidar field testing at Kennedy Space Center. NASA For the field test at Kennedy, Johnson led test operations and provided avionics and guidance, navigation, and control support. Engineers updated the computer’s firmware and software to support command and data interfacing with the lidar system. Team members from Johnson’s Flight Mechanics branch also designed a simplified motion compensation algorithm and NASA’s Jet Propulsion Laboratory in Southern California contributed a hazard detection algorithm, both of which were added to the lidar software by Goddard. Support from NASA contractors Draper Laboratories and Jacobs Engineering played key roles in the test’s success.
Primary flight test objectives were achieved on the first day of testing, allowing the lidar team time to explore different settings and firmware updates to improve system performance. The data confirmed the sensor’s capability in a challenging, vibration-heavy environment, producing usable maps. Preliminary review of the recorded sensor data shows excellent reconstruction of the hazard field terrain.

NASA Beyond lunar applications, SPLICE technologies are being considered for use on Mars Sample Return, the Europa Lander, Commercial Lunar Payload Services flights, and Gateway. The DLC design is also being evaluated for potential avionics upgrades on Artemis systems.
Additionally, SPLICE is supporting software tests for the Advancement of Geometric Methods for Active Terrain Relative Navigation (ATRN) Center Innovation Fund project, which is also part of Johnson’s Aeroscience and Flight Mechanics Division. The ATRN is working to develop algorithms and software that can use data from any active sensor – one measuring signals that were reflected, refracted, or scattered by a body’s surface or its atmosphere – to accurately map terrain and provide absolute and relative location information. With this type of system in place, spacecraft will not need external lighting sources to find landing sites.
With additional suborbital flight tests planned through 2026, the SPLICE team is laying the groundwork for safer, more autonomous landings on the Moon, Mars, and beyond. As NASA prepares for its next era of exploration, SPLICE will be a key part of the agency’s evolving landing, guidance, and navigation capabilities.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
JunoCam, the visible light imager aboard NASA’s Juno, captured this enhanced-color view of Ju-piter’s northern high latitudes from an altitude of about 36,000 miles (58,000 kilometers) above the giant planet’s cloud tops during the spacecraft’s 69th flyby on Jan. 28, 2025. Image data: NASA/JPL-Caltech/SwRI/MSSS Image processing: Jackie Branc (CC BY) New data from the agency’s Jovian orbiter sheds light on the fierce winds and cyclones of the gas giant’s northern reaches and volcanic action on its fiery moon.
NASA’s Juno mission has gathered new findings after peering below Jupiter’s cloud-covered atmosphere and the surface of its fiery moon, Io. Not only has the data helped develop a new model to better understand the fast-moving jet stream that encircles Jupiter’s cyclone-festooned north pole, it’s also revealed for the first time the subsurface temperature profile of Io, providing insights into the moon’s inner structure and volcanic activity.
Team members presented the findings during a news briefing in Vienna on Tuesday, April 29, at the European Geosciences Union General Assembly.
“Everything about Jupiter is extreme. The planet is home to gigantic polar cyclones bigger than Australia, fierce jet streams, the most volcanic body in our solar system, the most powerful aurora, and the harshest radiation belts,” said Scott Bolton, principal investigator of Juno at the Southwest Research Institute in San Antonio. “As Juno’s orbit takes us to new regions of Jupiter’s complex system, we’re getting a closer look at the immensity of energy this gas giant wields.”

While Juno’s microwave radiometer (MWR) was designed to peer beneath Jupiter’s cloud tops, the team has also trained the instrument on Io, combining its data with Jovian Infrared Auroral Mapper (JIRAM) data for deeper insights.
“The Juno science team loves to combine very different datasets from very different instruments and see what we can learn,” said Shannon Brown, a Juno scientist at NASA’s Jet Propulsion Laboratory in Southern California. “When we incorporated the MWR data with JIRAM’s infrared imagery, we were surprised by what we saw: evidence of still-warm magma that hasn’t yet solidified below Io’s cooled crust. At every latitude and longitude, there were cooling lava flows.”
The data suggests that about 10% of the moon’s surface has these remnants of slowly cooling lava just below the surface. The result may help provide insight into how the moon renews its surface so quickly as well as how as well as how heat moves from its deep interior to the surface.
“Io’s volcanos, lava fields, and subterranean lava flows act like a car radiator,” said Brown, “efficiently moving heat from the interior to the surface, cooling itself down in the vacuum of space.”
Looking at JIRAM data alone, the team also determined that the most energetic eruption in Io’s history (first identified by the infrared imager during Juno’s Dec. 27, 2024, Io flyby) was still spewing lava and ash as recently as March 2. Juno mission scientists believe it remains active today and expect more observations on May 6, when the solar-powered spacecraft flies by the fiery moon at a distance of about 55,300 miles (89,000 kilometers).

Data from the mission indicates these storms are enduring fea-tures.NASA/JPL-Caltech/SwRI/ASI/INAF/JIRAM Colder Climes
On its 53rd orbit (Feb 18, 2023), Juno began radio occultation experiments to explore the gas giant’s atmospheric temperature structure. With this technique, a radio signal is transmitted from Earth to Juno and back, passing through Jupiter’s atmosphere on both legs of the journey. As the planet’s atmospheric layers bend the radio waves, scientists can precisely measure the effects of this refraction to derive detailed information about the temperature and density of the atmosphere.
So far, Juno has completed 26 radio occultation soundings. Among the most compelling discoveries: the first-ever temperature measurement of Jupiter’s north polar stratospheric cap reveals the region is about 11 degrees Celsius cooler than its surroundings and is encircled by winds exceeding 100 mph (161 kph).
Polar Cyclones
The team’s recent findings also focus on the cyclones that haunt Jupiter’s north. Years of data from the JunoCam visible light imager and JIRAM have allowed Juno scientists to observe the long-term movement of Jupiter’s massive northern polar cyclone and the eight cyclones that encircle it. Unlike hurricanes on Earth, which typically occur in isolation and at lower latitudes, Jupiter’s are confined to the polar region.
By tracking the cyclones’ movements across multiple orbits, the scientists observed that each storm gradually drifts toward the pole due to a process called “beta drift” (the interaction between the Coriolis force and the cyclone’s circular wind pattern). This is similar to how hurricanes on our planet migrate, but Earthly cyclones break up before reaching the pole due to the lack of warm, moist air needed to fuel them, as well as the weakening of the Coriolis force near the poles. What’s more, Jupiter’s cyclones cluster together while approaching the pole, and their motion slows as they begin interacting with neighboring cyclones.
“These competing forces result in the cyclones ‘bouncing’ off one another in a manner reminiscent of springs in a mechanical system,” said Yohai Kaspi, a Juno co-investigator from the Weizmann Institute of Science in Israel. “This interaction not only stabilizes the entire configuration, but also causes the cyclones to oscillate around their central positions, as they slowly drift westward, clockwise, around the pole.”
The new atmospheric model helps explain the motion of cyclones not only on Jupiter, but potentially on other planets, including Earth.
“One of the great things about Juno is its orbit is ever-changing, which means we get a new vantage point each time as we perform a science flyby,” said Bolton. “In the extended mission, that means we’re continuing to go where no spacecraft has gone before, including spending more time in the strongest planetary radiation belts in the solar system. It’s a little scary, but we’ve built Juno like a tank and are learning more about this intense environment each time we go through it.”

Intuitive Machines’ IM-2 captured an image March 6, 2025, after landing in a crater from the Moon’s South Pole. The lunar lander is on its side near the intended landing site, Mons Mouton. In the center of the image between the two lander legs is the Polar Resources Ice Mining Experiment 1 suite, which shows the drill deployed.Intuitive Machines NASA’s PRIME-1 (Polar Resources Ice Mining Experiment 1) mission was designed to demonstrate technologies to help scientists better understand lunar resources ahead of crewed Artemis missions to the Moon. During the short-lived mission on the Moon, the performance of PRIME-1’s technology gave NASA teams reason to celebrate.
“The PRIME-1 mission proved that our hardware works in the harshest environment we’ve ever tested it in,” said Janine Captain, PRIME-1 co-principal investigator and research chemist at NASA’s Kennedy Space Center in Florida. “While it may not have gone exactly to plan, this is a huge step forward as we prepare to send astronauts back to the Moon and build a sustainable future there.”
Intuitive Machines’ IM-2 mission launched to the Moon on Feb. 26, 2025, from NASA Kennedy’s Launch Complex 39A, as part of the company’s second Moon delivery for NASA under the agency’s CLPS (Commercial Lunar Payload Services) initiative and Artemis campaign. The IM-2 Nova-C lunar lander, named Athena, carried PRIME-1 and its suite of two instruments: a drill known as TRIDENT (The Regolith and Ice Drill for Exploring New Terrain), designed to bring lunar soil to the surface; and a mass spectrometer, Mass Spectrometer Observing Lunar Operations (MSOLO), to study TRIDENT’s drill cuttings for the presence of gases that could one day help provide propellant or breathable oxygen to future Artemis explorers.
The IM-2 mission touched down on the lunar surface on March 6, just around 1,300 feet (400 meters) from its intended landing site of Mons Mouton, a lunar plateau near the Moon’s South Pole. The Athena lander was resting on its side inside a crater preventing it from recharging its solar cells, resulting in an end of the mission.
“We were supposed to have 10 days of operation on the Moon, and what we got was closer to 10 hours,” said Julie Kleinhenz, NASA’s lead systems engineer for PRIME-1, as well as the in-situ resource utilization system capability lead deputy for the agency. “It was 10 hours more than most people get so I am thrilled to have been a part of it.”
Kleinhenz has spent nearly 20 years working on how to use lunar resources for sustained operations. In-situ resource utilization harnesses local natural resources at mission destinations. This enables fewer launches and resupply missions and significantly reduces the mass, cost, and risk of space exploration. With NASA poised to send humans back to the Moon and on to Mars, generating products for life support, propellants, construction, and energy from local materials will become increasingly important to future mission success.
“In-situ resource utilization is the key to unlocking long-term exploration, and PRIME-1 is helping us lay this foundation for future travelers.” Captain said.
The PRIME-1 technology also set out to answer questions about the properties of lunar regolith, such as soil strength. This data could help inform the design of in-situ resource utilization systems that would use local resources to create everything from landing pads to rocket fuel during Artemis and later missions.
“Once we got to the lunar surface, TRIDENT and MSOLO both started right up, and performed perfectly. From a technology demonstrations standpoint, 100% of the instruments worked.” Kleinhenz said.
The lightweight, low-power augering drill built by Honeybee Robotics, known as TRIDENT, is 1 meter long and features rotary and percussive actuators that convert energy into the force needed to drill. The drill was designed to stop at any depth as commanded from the ground and deposit its sample on the surface for analysis by MSOLO, a commercial off-the-shelf mass spectrometer modified by engineers and technicians at NASA Kennedy to withstand the harsh lunar environment. Designed to measure the composition of gases in the vicinity of the lunar lander, both from the lander and from the ambient exosphere, MSOLO can help NASA analyze the chemical makeup of the lunar soil and study water on the surface of the Moon.
Once on the Moon, the actuators on the drill performed as designed, completing multiple stages of movement necessary to drill into the lunar surface. Prompted by commands from technicians on Earth, the auger rotated, the drill extended to its full range, the percussion system performed a hammering motion, and the PRIME-1 team turned on an embedded core heater in the drill and used internal thermal sensors to monitor the temperature change.
While MSOLO was able to perform several scans to detect gases, researchers believe from the initial data that the gases detected were all anthropogenic, or human in origin, such as gases vented from spacecraft propellants and traces of Earth water. Data from PRIME-1 accounted for some of the approximately 7.5 gigabytes of data collected during the IM-2 mission, and researchers will continue to analyze the data in the coming months and publish the results.

Nemanja Jovanovic, lead instrument scientist at Caltech, presents at the Emerging Technologies for Astrophysics workshop, held at NASA’s Ames Research Center in California’s Silicon Valley. The workshop brought together experts in astrophysics to discuss how advanced technologies could impact future mission planning.NASA/Donald Richey The future of astrophysics research could unlock the secrets of the universe, and emerging technologies like artificial intelligence, quantum sensing, and advanced materials may hold the key to faster, more efficient discovery. Advancements and implementations of new technologies are imperative for observational astrophysics to achieve the next level of detection.
NASA’s Emerging Technologies for Astrophysics workshop brought together subject matter experts from industry, government, and academia to explore the state of new and disruptive technologies. The meeting was an effort to identify specific applications for astrophysics missions and better understand how their infusion into future NASA space telescopes could be accelerated.
The workshop took place at NASA’s Ames Research Center in California’s Silicon Valley,. supporting the agency’s efforts to make partnership with public and private industry and collaborative mission planning possible.
“The profound questions about the nature of our universe that astrophysics at NASA answers require giant leaps in technology,” explained Mario Perez, chief technologist for the Astrophysics Division at NASA Headquarters in Washington. “Spotting potential in early-stage tech by encouraging discussions between imaginative researchers helps expand the scope of science and lessen the time required to achieve the next generation of astrophysics missions.”
Emerging technologies like artificial intelligence can support the design and optimization of future missions, and participants focused efforts on combining technologies to push research further. “Cross-pollination” of advanced materials like composites with advanced manufacturing, metamaterials, and photonic chips could support advancement in imaging missions beyond existing mechanical stability needs.
The United Nations Educational, Scientific and Cultural Organization (UNESCO) has dubbed 2025 the “International Year of Quantum Science and Technology” in recognition of a century of quantum mechanics. Workshop participants discussed how quantum sensing could enable more precise measurements, achieve “super resolution” by filling in missing details in lower resolution images, and provide greater capabilities in forthcoming space telescopes.
“This gathering of experts was an opportunity to find ways where we can increase the capabilities of future space instrumentation and accelerate technology development for infusion into NASA astrophysics missions,” said Naseem Rangwala, astrophysics branch chief at NASA Ames. “We can speed up the process of how we develop these future projects by using the emerging technologies that are incubated right here in Silicon Valley.”
The findings from this workshop and ongoing discussions will support efforts to study and invest in technologies to advance astrophysics missions with greater speed and efficiency.

Multinational corporations are using the M2M Intelligence platform in data centers and other settings. The system offers automated, secure communications on a ground-based global 5G network. Getty Images Artificial intelligence (AI) is advancing rapidly, as intelligent software proves capable of various tasks. The technology usually requires a “human in the loop” to train it and ensure accuracy. But long before the arrival of today’s generative artificial intelligence, a different kind of AI was born with the help of NASA’s Ames Research Center in California’s Silicon Valley — one that only exists between machines, running without any human intervention.
In 2006, Geoffrey Barnard founded Machine-to-Machine Intelligence Corp. (M2Mi) at Ames’ NASA Research Park, envisioning an automated, satellite-based communication network. NASA Ames established a Space Act Agreement with the company to develop artificial intelligence that would automate communications, privacy, security, and resiliency between satellites and ground-based computers.
Central to the technology was automating a problem-solving approach known as root cause analysis, which NASA has honed over decades. This methodology seeks to identify not only the immediate cause of a problem but also all the factors that contributed to the cause. This would allow a network to identify its own issues and fix itself.
NASA Ames’ director of nanotechnology at the time wanted to develop a communications network based on small, low-powered satellites, so Ames supported M2Mi in developing the necessary technology.
Barnard, now CEO and chief technology officer of Tiburon, California-based branch of M2Mi, said NASA’s support laid the foundation for his company, which employs the same technology in a ground-based network.
The company’s M2M Intelligence software performs secure, resilient, automated communications on a system that runs across hundreds of networks, connecting thousands of devices, many of which were not built to communicate with each other. The M2Mi company worked with Vodafone of Berkshire, England, to build a worldwide network across more than 500 smaller networks in over 190 countries. The companies M2M Wireless and TriGlobal have begun using M2M Intelligence for transportation logistics.
With NASA’s help, emerging industries are getting the boost they need to rapidly develop technologies to enhance our lives.
