Debate about mysterious Mars streaks finally put to rest?

Slope streaks in the Acheron Fossae of Mars. Credit: HiRISE, MRO, LPL (U. Arizona), NASA Dark streaks of unknown origin which appear spontaneously on Martian slopes before fading slowly over years to decades have puzzled planetary scientists since they were first observed in the late 1970s. These odd features, known as slope streaks, are generally darker than their surroundings and extend for hundreds of meters down steep terrain. In 2011 astron…

Ultraviolet And Biological Effective Dose Observations At Gale Crater, Mars - Astrobiology

The incident ultraviolet (UV) irradiance on the surface of Mars is strongly sterilizing and plays a critical role in atmospheric and near-surface photochemistry. The Rover Environmental Monitoring Station (REMS) instrument, which includes the first UV sensor sent to Mars on board the Curiosity rover, has been measuring the UV irradiance at Gale Crater since 2012, […] The post Ultraviolet And Biological Effective Dose Observations At Gale Crater,…

Mars Streaks: New Research Flags Possible Causes

Bright and dark streaks on Mars has sparked decades of debate. Some experts interpret them as streaks, also cited as recurring slope lineae (RSL), created by flows of salty water, or brine, that could remain liquid long enough to form them. If so, perhaps they offer rare habitable zones on the Red Planet, a world […]

Study Suggests Streaked Slopes on Mars May Not Indicate Water Flow

A groundbreaking study led by planetary scientists from Brown University and the University of Bern in Switzerland has fundamentally challenged long-held assumptions about the presence of water on Mars. For decades, researchers have been puzzled by the enigmatic streaks observed on the Martian surface, interpreting them as potential indicators of liquid water flows, thus implying that habitable conditions may exist on the Red Planet today. Howev…

A recent study by scientists from Brown University (USA) and the University of Bern (Switzerland) challenges the established hypothesis about the presence of liquid water on the surface of Mars. For a long time, dark lines extending hundreds of meters along the slopes of craters and mountains on Mars were considered evidence of flowing water. However, the results of an extensive analysis of orbital data show that these lines are most likely... T…
