NASA’s next Mars helicopters will survey the Red Planet to collect science data and scout areas to uncover clues about climate history and the presence of potential subsurface ice.

NASA’s SkyFall Mars Helicopters
NASA’s SkyFall mission will use an innovative mid-air deployment, delivering a team of three Mars helicopters evolved from the Ingenuity design, to map subsurface ice and demonstrate scouting and aerial mapping of potential landing sites for human-scale exploration. SkyFall continues to build on the heritage of Ingenuity with enhanced payload capability, extended operational range, with no rover required for communications relay. NASA announced the mission as part of the agency’s “Ignition” event on March 24, 2026.

There, SR-1 Freedom will release SkyFall, which will enter the Martian atmosphere and deploy its helicopters mid-air.
SkyFall Entry, Descent, and Landing
The Mars Entry, Descent, and Landing sequence (EDL) gets redefined with the SkyFall maneuver, in which rotorcraft are released midair during descent, enabling them to fly themselves safely to the Martian surface for the very first time.
SkyFall Science
The three SkyFall helicopters will carry an advanced instrument package featuring ground-penetrating radar and imagers, and they will be capable of measuring air temperature, wind speed, and direction. The radar will collect data about subsurface features that can be combined with data from the imagers, which could help map the terrain and characterize environments on Mars that are different from those we have explored before. If subsurface ice is detected, these measurements may help determine its extent and depth, which could help scientists understand potential formation mechanisms and implications for Mars’ climate history.
Each SkyFall helicopter is equipped with a suite of integrated operational and scientific instruments:
Subsurface Mapping: A compact ground-penetrating radar (GPR) designed to characterize subsurface geological structures and detect the presence of ice between depths of 1.6 to 10 feet (0.5 to 3.0 meters).
Visible Light Imagery: 13-megapixel color cameras to capture overlapping mid-flight views, generating centimeter-scale 3D terrain maps. This data is used to determine fine surface details and geological changes over time, while identifying small hazards to certify safe landing zones for future crewed Mars missions.
Infrared Surface Mapping: Specialized near-IR cameras to analyze to analyze the composition of Martian regolith — loose rocks, dust, and other surface material — and characterize these features beyond the visual spectrum.
Advanced Meteorology: Specialized sensors will profile ambient air temperatures. In addition, by leveraging the platform’s unique ability to hover, the helicopters will measure wind speed and direction across various elevations.
Radiation Monitoring: A dedicated commercial off-the-shelf (COTS) Micro Dosimeter, with direct flight heritage on the Lunar Reconnaissance Orbiter (LRO), will systematically measure and record total surface ionizing radiation doses to assess long-term safety environments for human explorers.
Atmospheric Dynamics: Combined readings — multi-altitude wind data with visual and infrared imaging — will provide insights about dust-transport mechanisms across the Martian surface.
Ground-Penetrating Radar
The Rundown on SkyFall
Where to Land?
SkyFall’s landing site has not yet been selected. A landing site selection process is being planned to determine the best possible landing sites for SkyFall to maximize the scientific return of the helicopters and their payloads, keeping within the capabilities of the Entry, Descent, and Landing system. Flat, low-elevation areas, free of many geological obstacles on Mars are being targeted. Those with potentially interesting subsurface features either within the landing ellipse or nearby could be particularly valuable to investigate with the planned science payload.
But First, They’ll Fly
The mission design includes a daring mid-air deployment during initial descent — hence the name “SkyFall.” This eliminates the need and cost for a lander. A parachute and then braking rockets will slow the SkyFall descent stage, and the three aircraft will fly off and land individually.
Ground Truth
The ground-penetrating radar on each of the SkyFall helicopters will scan the upper 10 feet (3.0 meters) of the Martian crust — and even deeper under ideal conditions — to differentiate layered dust, rock, and ice, in effect “reading” the strata resulting from changes in the planet’s climate, and offering clues to why it turned from warm and wet to frozen desert. The radar will also reveal hidden unstable areas — underground voids, hollow lava tubes, and weak regolith layers — that could make a landing site treacherous for robotic or crewed missions. Future astronauts could use the subsurface ice to provide breathable oxygen and rocket fuel for the trip home. The SkyFall helicopters will independently transmit their findings to spacecraft orbiting Mars, unlike Ingenuity, which had to use the Perseverance rover as a relay station.
Zone Coverage
During a single flight (approximately 2.5 minutes), one SkyFall helicopter is expected to cover about 0.6 to 1.2 miles of Martian surface (about 1 to 2 kilometers). With high-resolution visible-light and near-infrared cameras complementing ground-penetrating radar, the SkyFall helicopters will deliver surface and subsurface mapping — with a level of detail not possible from orbit, and covering a range faster than conventional rovers.
The Wright Stuff
NASA’s Ingenuity Mars Helicopter made aviation and space exploration history when it became the first aircraft to fly on another planet, April 19, 2021. When that lightweight helicopter arrived on Mars, attached to the underside of the Perseverance rover, its goal was to survive a month and make up to five flights. Instead, it flew 72 times over 2½ years, proving that powered, controlled flight was possible in the thin Martian atmosphere. SkyFall builds on Ingenuity’s legacy and proven technology.

The Legacy of Ingenuity
After making history with its initial test flights, Ingenuity embarked on a new mission as an operations demonstration, serving as an aerial scout for mission scientists and rover planners. In its final phase, the helicopter entered a new engineering demonstration period where it executed experimental flight tests that further expanded the team’s knowledge of the vehicle’s aerodynamic limits. Designed to be a monthlong technology demonstration, Ingenuity broke expectations, going higher, farther, and faster than previously imagined. It flew for the last time on Jan. 18, 2024.

Flight Heritage
The SkyFall helicopters will utilize or adapt proven features and capabilities from the Ingenuity technology demonstration, including:
Structure
Rotors
Motors
Landing gear
Flight software
Autonomous navigation
Significant improvements in the Ingenuity design were subsequently made through development work on a sample fetch helicopter design to scale up the lift capacity, partially by increasing the size and speed of the rotor blades. That carrying capability now allows the SkyFall helicopter to carry the ground-penetrating radar and other science instruments. A separate technology development that is enabling for SkyFall is an ultra low-mass direct-to-orbit communications radio, which allows the SkyFall helicopters to operate independently by transmitting commands to/from Earth via orbiters at Mars (as opposed to relaying via a rover or lander, as Ingenuity did). The lessons learned from Ingenuity’s 72 flights on Mars directly informed the helicopter team’s p …
