A SpaceX Falcon 9 rocket stands vertical on Tuesday, Feb. 25, 2025, at Launch Complex 39A at NASA’s Kennedy Space Center ahead of Intuitive Machines’ IM-2 mission as part of the agency’s Commercial Lunar Payload Services initiative and Artemis campaign. SpaceX Sending instruments to the Moon supports a growing lunar economy on and off Earth, and the next flight of NASA science and technology is only days away. NASA’s CLPS (Commercial Lunar Payload Services) initiative is a lunar delivery service that sends NASA science and technology instruments to various geographic locations on the Moon using American companies. These rapid, cost-effective commercial lunar missions at a cadence of about two per year improve our understanding of the lunar environment in advance of future crewed missions to the Moon as part of the agency’s broader Artemis campaign.
Of the 11 active CLPS contracts, there have been three CLPS launches to date: Astrobotic’s Peregrine Mission One, which collected data in transit but experienced an anomaly that prevented it from landing on the Moon; Intuitive Machines’ IM-1 mission, which landed, tipped over, and operated on the lunar surface; and Firefly Aerospace’s Blue Ghost Mission One that is currently enroute and scheduled to land in early March 2025. The CLPS contract awards cover end-to-end commercial payload delivery services, including payload integration, launch from Earth, landing on the surface of the Moon, and mission operations.
NASA’s fourth CLPS flight is from Intuitive Machines with their IM-2 mission. The IM-2 mission is carrying NASA science and technology instruments to Mons Mouton, a lunar plateau just outside of 5 degrees of the South Pole of the Moon, closer to the pole than any preceding lunar mission.
Scheduled to launch no earlier than Wednesday and land approximately eight days later, Intuitive Machines’ Nova-C lander, named Athena, will carry three NASA instruments to the lunar South Pole region – the Polar Resources Ice Mining Experiment-1 (PRIME-1) suite and the Laser Retroreflector Array (LRA).
The PRIME-1 suite consists of two instruments, the TRIDENT drill (The Regolith Ice Drill for Exploring New Terrain) and MSolo (Mass Spectrometer observing lunar operations), which will work together to extricate lunar soil samples, known as regolith, from the subsurface and analyze their composition to further understand the lunar environment and gain insight on potential resources that can be extracted for future examination.
The meter-long TRIDENT drill is designed to extract lunar regolith, up to about three feet below the surface. It will also measure soil temperature at varying depths below the surface, which will help to verify existing lunar thermal models that are used for ice stability calculations and resource mapping. By drilling into the lunar regolith, information is gathered to help answer questions about the lunar regolith geotechnical properties, such as soil strength, both at the surface and in the subsurface that will help inform Artemis infrastructure objectives. The data will be beneficial when designing future systems for on-site resource utilization that will use local resources to create everything from landing pads to rocket fuel. The lead development organization for TRIDENT is Honeybee Robotics, a Blue Origin Company.
The MSOLO instrument is a mass spectrometer capable of identifying and quantifying volatiles (or gasses that easily evaporate) found at or beneath the lunar surface, including– if it’s present in the regolith within the drill’s reach – water and oxygen, brought to the surface by the TRIDENT drill. This instrument can also detect any gases that emanate from the lander, drilling process, and other payloads conducting operations on the surface. Using MSolo to study the volatile gases found on the Moon can help us understand how the lander’s presence might alter the local environment. The lead development organization is INFICON of Syracuse, New York, in partnership with NASA’s Kennedy Space Center in Florida.
NASA’s LRA is 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 LRA instrument is passive, meaning it does not power on. It will function as a permanent location marker on the Moon for decades to come, similar to its predecessors. The lead development organization is NASA’s Goddard Space Flight Center in Greenbelt, Maryland.
In addition to the CLPS instruments, two technology demonstrations aboard IM-2 were developed through NASA’s Tipping Point opportunity. These are collaborations with the agency’s Space Technology Mission Directorate and industry that support development of commercial space capabilities and benefit future NASA missions.
Intuitive Machines developed a small hopping robot, Grace, named after Grace Hopper, computer scientist and mathematician. Grace will deploy as a secondary payload from the lander and enable high-resolution imaging and science surveying of the lunar surface, including permanently shadowed craters around the landing site. Grace is designed to bypass obstacles such as steep inclines, boulders, and craters to cover a lot of terrain while moving quickly, which is a valuable capability to support future missions on the Moon and other planets, including Mars.
Nokia will test a Lunar Surface Communications System that employs the same cellular technology here on Earth. Reconceptualized by Nokia Bell Labs to meet the unique requirements of a lunar mission, this tipping point technology aims to demonstrate proximity communications between the lander, a Lunar Outpost rover, and the hopper.
Launching as a rideshare alongside the IM-2 mission, NASA’s Lunar Trailblazer spacecraft also will begin its journey to lunar orbit where it will map the distribution of water – and other forms of water – on the Moon.
Future CLPS flights will continue to send payloads to the near side, far side, and South Pole regions of the Moon where investigations and exploration are informed by each area’s unique characteristics. With a pool of 13 American companies under CLPS, including a portfolio of 11 lunar deliveries by five vendors sending more than 50 individual science and technology instruments to lunar orbit and the surface of the Moon, NASA continues to advance long-term exploration of the Moon, and beyond to Mars.

5 Min Read NASA’s EZIE Launching to Study Magnetic Fingerprints of Earth’s Aurora
High above Earth’s poles, intense electrical currents called electrojets flow through the upper atmosphere when auroras glow in the sky. These auroral electrojets push about a million amps of electrical charge around the poles every second. They can create some of the largest magnetic disturbances on the ground, and rapid changes in the currents can lead to effects such as power outages. In March, NASA plans to launch its EZIE (Electrojet Zeeman Imaging Explorer) mission to learn more about these powerful currents, in the hopes of ultimately mitigating the effects of such space weather for humans on Earth.
Results from EZIE will help NASA better understand the dynamics of the Earth-Sun connection and help improve predictions of hazardous space weather that can harm astronauts, interfere with satellites, and trigger power outages.
The EZIE mission includes three CubeSats, each about the size of a carry-on suitcase. These small satellites will fly in a pearls-on-a-string formation, following each other as they orbit Earth from pole to pole about 350 miles (550 kilometers) overhead. The spacecraft will look down toward the electrojets, which flow about 60 miles (100 kilometers) above the ground in an electrified layer of Earth’s atmosphere called the ionosphere.
During every orbit, each EZIE spacecraft will map the electrojets to uncover their structure and evolution. The spacecraft will fly over the same region 2 to 10 minutes apart from one another, revealing how the electrojets change.

NASA’s EZIE (Electrojet Zeeman Imaging Explorer) mission will use three CubeSats to map Earth’s auroral electrojets — intense electric currents that flow high above Earth’s polar regions when auroras glow in the sky. As the trio orbits Earth, each satellite will use four dishes pointed at different angles to measure magnetic fields created by the electrojets. NASA/Johns Hopkins APL/Steve Gribben Previous ground-based experiments and spacecraft have observed auroral electrojets, which are a small part of a vast electric circuit that extends 100,000 miles (160,000 kilometers) from Earth to space. But for decades, scientists have debated what the overall system looks like and how it evolves. The mission team expects EZIE to resolve that debate.
“What EZIE does is unique,” said Larry Kepko, EZIE mission scientist at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. “EZIE is the first mission dedicated exclusively to studying the electrojets, and it does so with a completely new measurement technique.”

This technique involves looking at microwave emission from oxygen molecules about 10 miles (16 kilometers) below the electrojets. Normally, oxygen molecules emit microwaves at a frequency of 118 Gigahertz. However, the electrojets create a magnetic field that can split apart that 118 Gigahertz emission line in a process called Zeeman splitting. The stronger the magnetic field, the farther apart the line is split.
Each of the three EZIE spacecraft will carry an instrument called the Microwave Electrojet Magnetogram to observe the Zeeman effect and measure the strength and direction of the electrojets’ magnetic fields. Built by NASA’s Jet Propulsion Laboratory (JPL) in Southern California, each of these instruments will use four antennas pointed at different angles to survey the magnetic fields along four different tracks as EZIE orbits.
The technology used in the Microwave Electrojet Magnetograms was originally developed to study Earth’s atmosphere and weather systems. Engineers at JPL had reduced the size of the radio detectors so they could fit on small satellites, including NASA’s TEMPEST-D and CubeRRT missions, and improved the components that separate light into specific wavelengths.

NASA’s EZIE (Electrojet Zeeman Imaging Explorer) mission will investigate Earth’s auroral electrojets, which flow high above Earth’s polar regions when auroras (northern and southern lights) glow. By providing unprecedented measurements of these electrical currents, EZIE will answer decades-old mysteries. Understanding these currents will also improve scientists’ capabilities for predicting hazardous space weather. NASA/Johns Hopkins APL The electrojets flow through a region that is difficult to study directly, as it’s too high for scientific balloons to reach but too low for satellites to dwell.
“The utilization of the Zeeman technique to remotely map current-induced magnetic fields is really a game-changing approach to get these measurements at an altitude that is notoriously difficult to measure,” said Sam Yee, EZIE’s principal investigator at the Johns Hopkins Applied Physics Laboratory (APL) in Laurel, Maryland.
The mission is also including citizen scientists to enhance its research, distributing dozens of EZIE-Mag magnetometer kits to students in the U.S. and volunteers around the world to compare EZIE’s observations to those from Earth. “EZIE scientists will be collecting magnetic field data from above, and the students will be collecting magnetic field data from the ground,” said Nelli Mosavi-Hoyer, EZIE project manager at APL.

The EZIE spacecraft will launch aboard a SpaceX Falcon 9 rocket from Vandenberg Space Force Base in California as part of the Transporter-13 rideshare mission with SpaceX via launch integrator Maverick Space Systems.
The mission will launch during what’s known as solar maximum — a phase during the 11-year solar cycle when the Sun’s activity is stronger and more frequent. This is an advantage for EZIE’s science.
“It’s better to launch during solar max,” Kepko said. “The electrojets respond directly to solar activity.”
The EZIE mission will also work alongside other NASA heliophysics missions, including PUNCH (Polarimeter to Unify the Corona and Heliosphere), launching in late February to study how material in the Sun’s outer atmosphere becomes the solar wind.
According to Yee, EZIE’s CubeSat mission not only allows scientists to address compelling questions that have not been able to answer for decades but also demonstrates that great science can be achieved cost-effectively.
“We’re leveraging the new capability of CubeSats,” Kepko added. “This is a mission that couldn’t have flown a decade ago. It’s pushing the envelope of what is possible, all on a small satellite. It’s exciting to think about what we will discover.”
The EZIE mission is funded by the Heliophysics Division within NASA’s Science Mission Directorate and is managed by the Explorers Program Office at NASA Goddard. APL leads the mission for NASA. Blue Canyon Technologies in Boulder, Colorado, built the CubeSats.
