Three robotic systems funded by NASA are converging on a single goal: proving that machines can scout, dig, and communicate on the lunar surface well enough to support a permanent human outpost. The Micro Nova Hopper, the TRIDENT drill, and the RASSOR excavator each solve a different piece of the puzzle, from mapping frozen craters to extracting water ice to moving regolith for construction. Together, they represent the clearest test yet of whether autonomous hardware can turn the Moon from a destination for brief visits into a place where people actually live.
A Hopper Named Grace Scouts the Darkest Craters
The hardest real estate to survey on the Moon sits in permanently shadowed regions near the south pole, where temperatures plunge below minus 200 degrees Celsius and sunlight never reaches the ground. Traditional rovers cannot easily descend into these craters and return. That is why Intuitive Machines developed the Micro Nova Hopper, an autonomous propulsive drone nicknamed “Grace” that launched as part of the IM-2 payload. Grace is designed to hop into a permanently shadowed region, gather data on ice deposits, and relay findings back to the lander, turning a single touchdown point into a much wider exploration footprint.
The hopper traces its funding to NASA’s 2020 Tipping Point program, which awarded Intuitive Machines $41.6 million to develop a small deployable vehicle capable of traveling more than 2.5 kilometers into craters. That range matters because many of the most promising ice deposits sit deep inside terrain that wheeled vehicles cannot reach without unacceptable risk. If Grace performs as intended, it will deliver the first close-range measurements from inside one of these frozen vaults, data that future Artemis crews will need before they can plan any serious water-extraction operation or site a long-term base near the lunar south pole.
Drilling for Water With TRIDENT and MSOLO
Knowing where ice exists is only half the problem. Confirming its concentration and accessibility requires drilling into the regolith and analyzing what comes out. That job belongs to PRIME-1, NASA’s in-situ resource utilization demonstration riding aboard the same IM-2 mission. PRIME-1 pairs two instruments: TRIDENT, a drill that bores to roughly a meter, and MSOLO, a mass spectrometer built to detect water and other volatiles in the extracted material. Working together, they are meant to answer a deceptively simple question: can machines reliably pull usable water from lunar soil at depths shallow enough to support industrial-scale operations?
The stakes are high because water is not just for drinking. As lunar scientist David Kring explained on NASA’s Gravity Assist podcast, “water is one of those very important ingredients for the sustenance of an astronaut. You need it to drink.” Beyond hydration, water can be split into hydrogen and oxygen for rocket propellant and breathable air, making it the single most valuable resource for any sustained presence on the Moon. If TRIDENT confirms extractable ice at shallow depths, it would validate years of orbital remote-sensing data and shift the conversation from “is there water?” to “how fast can we harvest it?” The absence of updated volatility analysis results from the drill, however, means the scientific community is still waiting for hard numbers on actual yield, a reminder that even well-funded hardware must still prove itself in the unforgiving conditions of the lunar surface.
RASSOR: The Excavator Built for Lunar Gravity
Even after water is located and confirmed, someone or something has to move enormous volumes of regolith to process it at scale. Enter the Regolith Advanced Surface Systems Operations Robot, known as RASSOR. Unlike conventional earthmoving equipment, RASSOR was designed from scratch for the Moon’s one-sixth gravity, where heavy machines lose much of the traction they enjoy on Earth. Its opposed bucket drums scoop soil from both sides simultaneously, generating enough downward force to dig without needing the massive weight that anchors terrestrial excavators. According to NASA’s patent documentation, RASSOR can dump material without a ramp and continue operating even if it flips over, thanks to a fully reversible drivetrain and symmetric geometry.
NASA envisions RASSOR supporting in-situ resource utilization, construction operations, and space mining. That breadth of application is what separates it from single-purpose science instruments that fly once and retire. A fleet of RASSOR units could, in theory, feed regolith into processing plants that extract oxygen and water, and then haul the leftover material to construction sites where it becomes building material for radiation shielding or landing pads. The concept is elegant, but it has not yet been tested in an integrated Artemis habitat scenario. No official NASA records currently document how RASSOR would plug into a full base architecture, which leaves a gap between the patent-level hardware description and the operational reality of a working lunar outpost that must run continuously for months or years.
Nokia’s LTE Network Ties the Machines Together
Autonomous robots are only as useful as the communications links that connect them. A hopper deep inside a shadowed crater, a drill on the surface, and an excavator hauling regolith all need reliable, low-latency data paths to coordinate. That is why NASA also awarded Nokia of America $14.1 million through the same 2020 Tipping Point program to deploy LTE/4G communications on the lunar surface, creating an infrastructure layer as essential as power or propellant. The Nokia Lunar Surface Communications System aboard IM-2 is designed to link the lander, a rover, and the hopper into a single network, effectively turning a patch of the Moon into a testbed for space-rated cellular technology.
A joint NASA and Nokia technical publication on lunar communications concepts describes a roadmap for extending 3GPP and 802.11 (Wi‑Fi) standards to future astronaut operations. The paper lays out environmental and operational constraints, including coverage range, signal reliability, and the need for mission-critical communications in extreme cold and darkness. What it does not yet provide is direct performance data from the lunar environment itself. Engineers are still working from models rather than field measurements. If the IM-2 LTE demo succeeds, it will generate the first real-world benchmarks for cellular networking on another world, benchmarks that every subsequent Artemis surface mission will likely use when designing its own communications and navigation systems.
From Robotic Pathfinders to a Living Moon
Although these technologies focus on the Moon, they are part of a much broader push to understand how humans and machines can operate together in extreme environments. NASA’s public-facing platforms, such as the NASA+ streaming hub, have increasingly highlighted the role of robotics and communications in exploration, using documentaries and live coverage to connect complex engineering work to everyday audiences. Within that catalog, the curated series collections often frame lunar missions as stepping stones in a longer arc that runs from Earth orbit to deep space. This underscores how each new robot or sensor is meant to answer a specific question about living off-world.
The same systems thinking shows up across NASA science. Research on our home planet, organized under the agency’s Earth science division, has long treated Earth as a complex, coupled system where atmosphere, oceans, land, and ice interact. That systems approach is now being exported outward, with lunar engineers considering how power, communications, mobility, and resource extraction will interlock on the Moon. At the other end of the scale, work in the Universe science portfolio explores galaxies, black holes, and cosmic structure. This provides the grand context that makes a single crater-hopping robot feel like part of a much larger story about humanity’s place in space. The Micro Nova Hopper, TRIDENT, RASSOR, and Nokia’s LTE system are thus more than isolated experiments: they are early building blocks in a networked, robotic infrastructure that could turn the Moon into a proving ground for living and working far from Earth.
