A groundbreaking study released on Monday, utilizing data collected by NASA’s Mars InSight lander, has revealed compelling evidence of liquid water existing deep below the surface of the fourth planet. This significant discovery not only advances the quest for life on Mars but also sheds light on the possible fate of the planet’s ancient oceans.
Since its arrival on the Red Planet in 2018, the InSight lander has been diligently collecting seismic data for over four years, analyzing the impact of Marsquakes on the planet’s crust and unveiling the composition of subterranean materials.
The researchers have found compelling evidence suggesting the presence of liquid water deep beneath the lander. Water, a key component for sustaining life, is believed to have existed on Mars’ surface in the form of lakes, rivers, and oceans over three billion years ago.
According to Vashan Wright from the University of California San Diego’s Scripps Institution of Oceanography, “The ingredients required for life as we know it exist in Mars’ subsurface, if our interpretations hold true.” The study points to substantial reservoirs of liquid water situated between 11.5 to 20 kilometers beneath the Martian surface as the most plausible explanation for the InSight data.
Moreover, the study suggests that the predicted volume of liquid water below Mars’ surface exceeds the estimated water levels of the hypothesized ancient Martian oceans. This finding underscores the importance of understanding Mars’ water cycle, investigating past surface water, searching for signs of past or existing life, and evaluating potential resources for future missions.
The study, authored by Vashan Wright, Matthias Morzfeld, and Michael Manga, emphasizes the transformative impact of collaborative human efforts in exploring and unraveling the mysteries of distant planets. This significant research was published in the Proceedings of the National Academy of Sciences during the week of Aug. 12.
Reflecting on this monumental achievement, Wright expressed hope that both the scientific community and the general public would find inspiration in the collective endeavor to unravel the secrets of Mars and expand the horizons of human understanding.
