NASA has examined thousands of “dark streaks” on Mars which
might have formed due to liquid water, ice or vapor. The results of the
study give “additional support for the notion that significant amounts
of near-surface water can be found on Mars today."
The agency posted a series of photographs obtained from the Valles Marineris region near Mars' equator which depict numerous dark lines found around the planet’s canyons.
According to the scientists, the mysterious streaks might be indications of the presence of either frozen or liquid water, or vapor.
Fast Facts:
› Big canyons on Mars hold thousands of seasonal dark streaks examined in a new study of such features, which might be signs of liquid water.
› The seasonal streaks at many locations are unlikely to result from underground water reaching the surface.
› Salts drawing water vapor from the atmosphere might be a key mechanism in how these streaks form, but puzzles and other possibilities remain.
