The study proposes injecting 9-micrometer-long rods, made from iron and aluminum found in Martian dust, into Mars’s atmosphere. These particles could trap heat and raise the planet’s temperature by more than 10°C within months, enough to sustain liquid water. This method could be more feasible than other proposed techniques, which involve transporting vast amounts of materials from Earth. By using materials already present on Mars, the researchers aim to sidestep the immense logistical challenges associated with interplanetary transport.
