Study casts doubt on water flows as cause of streaks on Martian slopes

Tuesday Telescope: Finally, some answers on those Martian streaks

Alas, these probably are not reservoirs of life.

NASA’s Mars Streak Mystery Might Finally Be Solved – And It’s Not Great News

A sweeping machine learning study scanning over 86,000 high-res Mars images reveals that the mysterious streaks seen on Martian slopes are likely dry dust slides, not evidence of flowing water as previously hoped. Long debated as possible indicators of present-day water (and thus habitability), these streaks—some recurring seasonally—now appear to be more aligned with wind [...]

Mystery Behind Unusual Markings on Mars Has Been Solved—And They Aren't What Researchers Hoped For

Hopes for flowing water on Mars appear dashed after recent work from Brown University and the University of Bern in Switzerland examined the cause behind mysterious markings on the red planet‘s surface. From the heights of Martian cliffsides and crater walls, unexplained streaks appear, with the possible flow of water put forward as one possible explanation for these intriguing markings on the Red Planet. If true, such assertions would indicate …

Major theory about potential for life on Mars called into question by researchers

The cause of one of the planet’s most iconic features remains a disputed topic

Dark streaks on Mars may not come from water after all, scientists say

Satellite images suggest long, dark streaks on Mars may not actually be related to water on the Red Planet.

Scientists Thought They Had Spotted Flowing Water on Mars. It Turned Out to Be Something Else Entirely.

Images sent back by NASA's Viking spacecraft in the 1970s revealed some unusual streaks stretching across the arid landscapes of Mars. The sighting had scientists excited about the possibility of free-flowing water on an otherwise desolate planet. The streaks — which, at times, were thousands of feet long — appeared much darker, contrasting against the mostly monotonal, surrounding hills, looking as if somebody had spilled an enormous glass of w…
