  • SwRI models hint at longer timescale for Mars formation

      SwRI models hint at longer timescale for Mars formation The early solar system was a chaotic place, with evidence indicating that Mars was likely struck by planetesimals, small protoplanets up to 1,200 miles in diameter, early in its history. Southwest Research Institute scientists modeled the mixing of materials associated with these impacts, revealing that…

  • New Insight into How Much Atmosphere Mars Lost

      New Insight into How Much Atmosphere Mars Lost A key tracer used to estimate how much atmosphere Mars lost can change depending on the time of day and the surface temperature on the Red Planet. Previous measurements of this tracer – isotopes of oxygen – have disagreed significantly. Getting an accurate measurement is important…
