• •A new study suggests that artificially engineered dust particles sourced from Mars itself could be used to raise temperatures on the Red Planet by more than 50 degrees Fahrenheit (30 degrees Celsius).
• •The researchers say that the process is more feasible than previous proposals because it uses resources already available on Mars and is 5,000 times more efficient.
• •The nanorods would be tiny, about 9 millionths of a meter in length, but would be designed to be half the wavelength of thermal radiation so as to more efficiently absorb heat leaking away from Mars.

A new study suggests that Mars could be terraformed using artificially engineered dust particles sourced from the Red Planet itself. The researchers say that this method is more feasible than other proposals, as it uses resources already available on the Red Planet and is 5,000 times more efficient.
