NASA’s First Moon Drones Won’t Fly. They’ll Hop.

NASA is sending drones to the Moon, and not one of them has a rotor. Firefly Aerospace won a $75 million subcontract to fly four hopping drones to the lunar south pole under a mission called MoonFall, with delivery targeted for no earlier than 2028.

NASA’s Jet Propulsion Laboratory is building the drones. Firefly’s job is getting them there, after which they’ll scout terrain, hunt for water ice, and mark the corners of a future moon base.

The MoonFall Contract

The $75 million subcontract splits the work cleanly. JPL designs, builds, and manages the four MoonFall drones. NASA sources the launch vehicle, and Firefly handles transport and delivery to the lunar surface.

That delivery runs on Firefly’s Elytra Dark, a spacecraft that can carry up to 2,205 pounds. Elytra Dark inherits its avionics, carbon composite structure, and Spectre engines from the company’s Blue Ghost Mission 1 lander, which means this hardware traces back to a vehicle Firefly has already flown to the Moon rather than a clean-sheet design.

The spacecraft transits for roughly 45 days before reaching lunar orbit. From there, it deploys the four hoppers at an altitude of about 31 miles above the south pole.

Why These Drones Hop Instead of Fly

Here’s the technical reality that separates a Moon drone from anything in a DJI catalog. The Moon has no atmosphere, and rotors need air to bite into. Nothing up there pushes back against a propeller, which makes a quadcopter on the lunar surface a paperweight.

So MoonFall’s drones move by propulsion. They fire engines to hop, arc over a stretch of terrain, and set back down.

NASA frames the concept as a descendant of the Ingenuity Mars helicopter, and at the institutional level that lineage is literal. JPL built Ingenuity, and JPL is building these.

The engineering is another matter. Ingenuity flew on rotors because Mars, thin as its air is, still has an atmosphere. The Moon offers none, so the only way to get airborne is to bring your own reaction mass and burn it.

That distinction matters for anyone who follows drone hardware. The word “drone” is doing heavy lifting here, and the resemblance to terrestrial aircraft ends with the name.

What the Hoppers Will Actually Do

As CBS News reports, the mission is reconnaissance. The hoppers will survey terrain, map the permanently shadowed regions near the pole, and scout for resources, water ice chief among them, in craters where a wheeled rover struggles to reach.

Each drone is built to operate through a single lunar day, about 14 Earth days, capturing high-definition optical imagery of the surface below. A survive-the-night payload is designed to keep working for several months after that first day, pushing data back well beyond the initial window.

They’ll also stake out the base itself. Carlos García-Galán, who manages NASA’s Moon Base program from agency headquarters, said the drones will “basically put them at the corners of the areas where we think we have either key scientific objectives or we want to build up the moon base.” The first survey markers of a permanent lunar settlement will be dropped by hopping robots.

That sprawl is not a design flourish. NASA says the base needs to cover hundreds of square miles partly because its planned nuclear power systems have to sit more than half a mile away from the habitat for radiation protection. When your power plant lives that far from your front door, your perimeter gets big, and you need a fast way to survey it.

The Bigger Moon Base Picture

MoonFall is one piece of a much larger build. NASA’s roadmap leans on Blue Origin for the landers that put hardware and crew on the surface, on Astrolab for a crewed lunar rover, and on Lunar Outpost for additional terrain vehicles. The whole effort is pegged at roughly $20 billion over seven years.

The timeline stacks up behind Artemis. After the Artemis II flyaround earlier this year, NASA is targeting crewed lander docking tests in mid-2027 and a first surface landing of two astronauts in 2028. MoonFall’s hoppers are meant to be on the ground doing survey work in that same window, scouting the real estate before boots arrive.

DroneXL’s Take

The part that doesn’t make the headline is the word “drone” itself. NASA and Firefly use it because it’s the term the public understands, but a thruster-powered hopper that runs through the lunar day and hands off to a survive-the-night payload has almost nothing in common with the aircraft this audience flies. It’s a great story, just not a quadcopter story, and the coverage blurring that line does readers a disservice.

What’s worth respecting is the engineering of the choice. Nobody at JPL pretended a rotor could work in a vacuum. They went to propulsive hopping because physics left them no other option, and they leaned on the Ingenuity playbook for the parts that do transfer: autonomy, lightweight design, and the basic idea that an aerial scout sees what a rover never will.

If MoonFall flies in 2028 and those four hoppers map the south pole and mark a base perimeter, it will be the first time anything we’d loosely call a drone operates off-world beyond Mars. That’s a milestone worth the hype, as long as we’re clear-eyed about what’s doing the flying. The rotor era stays on Earth, and the Moon belongs to the hoppers.
