Hassanalian Proposes 1,000s of Dandelion Drones to Map 746-Mile Martian Lava Tubes

Mostafa Hassanalian outlined a Mars-cave concept in which a pillbug-like robot drops through a skylight and releases thousands of wind-driven “dandelion drones” to survey lava tubes rovers cannot enter.
The design targets tunnels up to 250 meters wide and more than 1,200 kilometers long, where school-bus-sized rovers are impractical and surface winds can reach 60 mph.
Each drone would use piezoelectric power instead of solar panels, fly white-coated for thermal efficiency, and relay humidity, temperature and mapping data by radio from the dark cave interior.
A key unknown is whether Martian cave winds are strong enough, though Hassanalian says skylight ventilation could help and the carrier robot would bring a high-powered fan as backup.
The proposal joins a broader push into extraterrestrial caves after NASA’s 72 Ingenuity flights and European lava-tube tests in Spain, with Arsia Mons seen as a prime future target.
Can fragile 'dandelion' drones truly conquer the brutal, uncharted lava tubes of Mars?
Are these vast Martian caves humanity's future home, or just a tomb for our robots?
Could our drone swarm search for Martian life accidentally destroy it forever?
Swarm of 1,000 Dandelion-Inspired Micro-Drones: Biomimetic Solutions for Martian Lava Tube Exploration and Beyond
Overview
The Dandelion Drone Project, led by Mostafa Hassanalian at New Mexico Tech, is in an advanced research and prototyping phase as of May 2026. This project focuses on creating biomimetic micro-drones inspired by dandelion seeds. The main goal is to explore hard-to-reach places like Martian lava tubes, which traditional rovers cannot access due to their surface limitations. By mimicking the natural design of dandelion seeds, these micro-drones aim to overcome the challenges of navigating complex and confined environments, opening new possibilities for planetary exploration.
