NASA’s Mars 2020 “Perseverance” rover, China’s first Mars mission “Tianwen-1”, and the United Arab Emirates’ “Hope” Mars orbiter have all recently successfully launched to eventually orbit or land on the red planet. Their scheduled arrivals in seven months will undoubtedly advance our understanding of Mars. From the first fly-by space probes to more recent Mars rovers, “follow the water” is one of the key themes of martian exploration, as water, and volatiles more broadly, are essential for discovering extraterrestrial life and examining habitability.
In this talk, Kun Wang will reassess several key geochemical and isotopic constraints for the volatile budgets of Mars and Earth. He will also introduce K isotopes, a newly proposed tracer for comparing planetary volatiles.
