Ansari, Kite and Ramirez modelled artificial aerosols such as ~9-micrometre conductive nanorods made from Mars materials, finding they could warm Mars more than 5,000 times more effectively than the best greenhouse gases.

Hoffman, Hecht and colleagues reported MOXIE produced oxygen from Martian atmospheric CO2 by solid oxide electrolysis seven times in 2021, the first demonstration of in situ resource utilization on another planet.

Wordsworth, Kerber and Cockell showed through experiments and modelling that a thin layer of silica aerogel could warm regions of the Martian surface via a solid-state greenhouse effect, making them habitable to photosynthetic life.

Jakosky and Edwards inventoried CO2 reservoirs on Mars and concluded there is not enough accessible CO2 for significant greenhouse warming, so terraforming Mars is not possible with present-day technology.
