Editing Carbon monoxide (section)

===Proposed use as a rocket fuel ===
Carbon monoxide has been proposed for use as a fuel on Mars by NASA researcher [[Geoffrey Landis]]. [[Carbon monoxide/oxygen engine]]s have been suggested for early surface transportation use as both carbon monoxide and oxygen can be straightforwardly produced from the carbon dioxide [[atmosphere of Mars]] by [[zirconia]] [[electrolysis]], without using any [[Water on Mars|Martian water resources]] to obtain hydrogen, which would be needed to make methane or any hydrogen-based fuel.<ref name="landis2001">{{cite journal|last=Landis|date=2001|title=Mars Rocket Vehicle Using In Situ Propellants|journal=Journal of Spacecraft and Rockets|volume=38|issue=5|pages=730–735|bibcode=2001JSpRo..38..730L|doi=10.2514/2.3739}}</ref>

Landis also proposed manufacturing the fuel from the similar carbon dioxide atmosphere of Venus for a sample return mission, in combination with solar-powered UAVs and rocket balloon ascent.<ref name="o253">{{cite web |date=2024-01-04 |title=Sample Return from the Surface of Venus |url=https://www.nasa.gov/general/sample-return-from-the-surface-of-venus/ |access-date=2024-05-29 |website=NASA}}</ref>
