Researchers from NASA’s Jet Propulsion Laboratory in Southern California, private companies, and academic institutions are developing the first space-based quantum sensor for measuring gravity. Supported by NASA’s Earth Science Technology Office (ESTO), this mission will mark a first for quantum sensing and will pave the way for groundbreaking observations of everything from petroleum reserves to global supplies of fresh water.
A map of Earth’s gravity. Red indicates areas of the world that exert greater gravitational pull, while blue indicates areas that exert less. A science-grade quantum gravity gradiometer could one day make maps like this with unprecedented accuracy. Image Credit: NASA Earth’s gravitational field is dynamic, changing each day as geologic processes redistribute mass across our planet’s surface. The greater the mass, the greater the gravity.
You wouldn’t notice these subtle changes in gravity as you go about your day, but with sensitive tools called gravity gradiometers, scientists can map the nuances of Earth’s gravitational field and correlate them to subterranean features like aquifers and mineral deposits. These gravity maps are essential for navigation, resource management, and national security.
“We could determine the mass of the Himalayas using atoms,” said Jason Hyon, chief technologist for Earth Science at JPL and director of JPL’s Quantum Space Innovation Center. Hyon and colleagues laid out the concepts behind their Quantum Gravity Gradiometer Pathfinder (QGGPf) instrument in a recent paper in EPJ Quantum Technology.
Gravity gradiometers track how fast an object in one location falls compared to an object falling just a short distance away. The difference in acceleration between these two free-falling objects, also known as test masses, corresponds to differences in gravitational strength. Test masses fall faster where gravity is stronger.
QGGPf will use two clouds of ultra-cold rubidium atoms as test masses. Cooled to a temperature near absolute zero, the particles in these clouds behave like waves. The quantum gravity gradiometer will measure the difference in acceleration between these matter waves to locate gravitational anomalies.
Using clouds of ultra-cold atoms as test masses is ideal for ensuring that space-based gravity measurements remain accurate over long periods of time, explained Sheng-wey Chiow, an experimental physicist at JPL. “With atoms, I can guarantee that every measurement will be the same. We are less sensitive to environmental effects.”
Using atoms as test masses also makes it possible to measure gravity with a compact instrument aboard a single spacecraft. QGGPf will be around 0.3 cubic yards (0.25 cubic meters) in volume and weigh only about 275 pounds (125 kilograms), smaller and lighter than traditional space-based gravity instruments.
Quantum sensors also have the potential for increased sensitivity. By some estimates, a science-grade quantum gravity gradiometer instrument could be as much as ten times more sensitive at measuring gravity than classical sensors.
The main purpose of this technology validation mission, scheduled to launch near the end of the decade, will be to test a collection of novel technologies for manipulating interactions between light and matter at the atomic scale.
“No one has tried to fly one of these instruments yet,” said Ben Stray, a postdoctoral researcher at JPL. “We need to fly it so that we can figure out how well it will operate, and that will allow us to not only advance the quantum gravity gradiometer, but also quantum technology in general.”
This technology development project involves significant collaborations between NASA and small businesses. The team at JPL is working with AOSense and Infleqtion to advance the sensor head technology, while NASA’s Goddard Space Flight Center in Greenbelt, Maryland is working with Vector Atomic to advance the laser optical system.
Ultimately, the innovations achieved during this pathfinder mission could enhance our ability to study Earth, and our ability to understand distant planets and the role gravity plays in shaping the cosmos. “The QGGPf instrument will lead to planetary science applications and fundamental physics applications,” said Hyon.

Creating a golden streak in the night sky, a SpaceX Falcon 9 rocket carrying Intuitive Machines’ Nova-C lunar lander (IM-2) and NASA’s Lunar Trailblazer soars upward after liftoff from Launch Complex 39A at NASA’s Kennedy Space Center in Florida at 7:16 p.m. EST, Wednesday, Feb. 26. The IM-2 launch, which is part of NASA’s CLPS (Commercial Lunar Payload Services) initiative, is carrying NASA technology and science demonstrations, and other commercial payloads to Mons Mouton, a lunar plateau to advance our understanding of the Moon and planetary processes, while paving the way for future crewed missions. (Credit: NASA) The next set of NASA science and technology demonstrations is on its way to the lunar surface, where they will gather data about Earth’s nearest neighbor and help pave the way for American astronauts to explore the Moon and beyond, for the benefit of all.
Carrying NASA instruments as part of the agency’s CLPS (Commercial Lunar Payload Services) initiative and Artemis campaign, Intuitive Machines’ IM-2 mission launched at 7:16 p.m. EST, Feb. 26, aboard a SpaceX Falcon 9 rocket from Launch Complex 39A at the agency’s Kennedy Space Center in Florida. Intuitive Machines’ lunar lander is scheduled to touch down on Thursday, March 6, in Mons Mouton, a plateau in the Moon’s South Pole.
“With each CLPS mission, the United States is leading the way in expanding our reach and refining our capabilities, turning what was once dreams into reality,” said NASA acting Administrator Janet Petro. “These science and technology demonstrations are more than payloads – they represent the foundation for future explorers who will live and work on the Moon. By partnering with American industry, we are driving innovation, strengthening our leadership in space, and preparing for sending humans farther into the solar system, including Mars.”

Credit: Intuitive Machines Once on the Moon, the NASA CLPS investigations will aim to measure the potential presence of volatiles or gases from lunar soil – one of the first on-site demonstrations of resource use on the Moon. In addition, a passive Laser Retroreflector Array on the top deck of the lander will bounce laser light back at any future orbiting or incoming spacecraft to give them a permanent reference point on the lunar surface. Other technology instruments on this delivery will demonstrate a robust surface communications system and deploy a propulsive drone designed to hop across the lunar surface.
NASA’s Lunar Trailblazer spacecraft, which launched as a rideshare with the IM-2 mission, also began its journey to lunar orbit, where it will map the distribution of the different forms of water on the Moon. Lunar Trailblazer will discover where the Moon’s water is, what form it is in, and how it changes over time. Observations gathered during its two-year prime mission will contribute to the understanding of water cycles on airless bodies throughout the solar system while also supporting future human and robotic missions to the Moon by identifying where water is located.
NASA’s Artemis campaign includes conducting more science to better understand planetary processes and evolution, to search for evidence of water and other resources, and support long-term, sustainable human exploration.
The NASA science and technology instruments that launched aboard the IM-2 mission are:
Polar Resources Ice Mining Experiment-1 (PRIME-1): This experiment will explore the Moon’s subsurface and analyze where lunar resources may reside. The experiment’s two key instruments will demonstrate the ability to extract and analyze lunar soil to detect volatile chemical compounds that turn into gas. The two instruments will work in tandem: The Regolith and Ice Drill for Exploring New Terrains will drill into the Moon’s surface to collect samples, while the Mass Spectrometer Observing Lunar Operations will analyze these samples to determine the gas composition released across the sampling depth. The PRIME-1 technology will provide valuable data to better understand the Moon’s surface and how to work with and on it. Laser Retroreflector Array (LRA): This collection of eight retroreflectors will 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 is a passive optical instrument and will function as a permanent location marker on the Moon for decades to come. Micro Nova Hopper: Funded by NASA’s Space Technology Mission Directorate Tipping Point initiative, Intuitive Machines’ Micro Nova hopper, Grace, is designed to enable high-resolution surveying of the lunar surface under its flight path. This autonomous propulsive drone aims to deploy to the surface and hop into a nearby crater to survey the lunar surface and send science data back to the lander. It’s designed to hop in and out of a permanently shadowed region, providing a first look into undiscovered regions that may provide critical information to sustain a human presence on the Moon. Nokia Lunar Surface Communications System (LSCS): Also developed with funding from NASA’s Tipping Point initiative, Nokia’s LSCS 4G/LTE communications system will demonstrate cellular communications between the Intuitive Machines lander, a Lunar Outpost rover, and the Micro Nova hopper. Engineered to transmit high-definition video, command-and-control messages, and sensor and telemetry data, the LSCS aims to demonstrate an ultra-compact advanced communication solution for future infrastructure on the Moon and beyond.

Quantum computing, a transformative field leveraging quantum mechanics, has the potential to solve complex problems far beyond the reach of classical computers. While it promises significant advancements, it also poses risks, such as breaking cryptographic codes, threatening global data security.
For example: At NASA's Quantum Artificial Intelligence Laboratory (QuAIL), experiments revealed unprecedented computational power and successfully solved the unsolvable problem. However, the quantum computer began generating independent and unconventional outputs, leading to speculation that it could think for itself or even connect with extraterrestrial intelligence. Concerned about the implications, NASA halted its quantum computing project in 2023, though some believe the research continued in secret.
Separately, researchers have hypothesized that advanced extraterrestrial civilizations might use black holes as quantum computers for computation and communication. highlighting the mysterious potential of these quantum systems to explore phenomena beyond Earthly understanding.
A fictional scenario (watch video below) illustrates the dangers of quantum technology spiraling out of control:
A mysterious data transfer lights up NSA monitors at 3 AM. Within hours, hospital records flash across Times Square billboards. Dating app messages spill onto every screen in the city.
Bank accounts vanish. Traffic lights freeze. Autonomous vehicles crash through shopping malls. Intelligence agencies scramble as decades of encrypted messages suddenly unlock. Someone or something has broken the unbreakable - the mathematical foundations that protect everything from banking passwords to nuclear launch codes.
The quantum apocalypse arrives years ahead of schedule. But as chaos spreads, patterns start to surface. The timing seems too perfect, the targets too precise.
Deep beneath the Pentagon, analysts notice something strange: some messages were decrypted months ago. The chaos isn't random - it's cover for something bigger.
