Mars streaks are sand, not water, reports NASA News 21 November 2017, Science (AAAS) News 22 November 2017, Astronomy Now 26 November 2017, and Nature Geoscience doi:10.1038/s41561-017-0012-5, 20 November 2017.
Dark streaks on crater slopes that came and went with the passing seasons have been presented as evidence of liquid water flowing on the surface of Mars. These were first discovered in 2011 and named “recurrent slope lineae” (RSL). The streaks appeared at the top of the slopes at the beginning of warm seasons and gradually elongated down the slopes and then faded away in the cold seasons. On earth this regular cycle of streaks can be caused by seeping water.
A group of scientists led by Alfred McEwen of University of Arizona and Colin Dundas of U.S. Geological Survey have now analysed images taken by the High Resolution Imaging Science Experiment (HiRISE) camera on the Mars Reconnaissance Orbiter (MRO) and found that the streaks only occurred on slopes steeper than 27° and each streak ends at the same angle. Seeping water would continue to flow down slopes that are less steep than this.
The researchers concluded that the streaks “match the stopping angle for granular flows of cohesionless sand in active Martian aeolian dunes”. (Aeolian means wind-blown) Colin Dundas explained: “We’ve thought of RSL as possible liquid water flows, but the slopes are more like what we expect for dry sand. This new understanding of RSL supports other evidence that shows that Mars today is very dry”.
In spite of these results Alfred McEwen is still hopeful of finding life on Mars and elsewhere in the Solar System. In an interview with Science he stated: “It’s inconceivable to me that there aren’t places where there’s liquid water today within Mars. If there was ever life on Mars – that originated somewhere – why wouldn’t there still be life today in these underground pockets?”
When asked where else we could look for life he replied: “I’m heavily involved in one mission – the Europa Clipper. Extant life there is much more likely today than on the surface of Mars. On the other hand, they’re further away, and Europa in particular is in a harsh radiation environment”.
Editorial Comment: Yet another failure to find water on Mars in a long line of expensive evolutionist disappointments. (See our report Sand, Not Water, Flowed on Mars). The Mars Reconnaissance Orbiter was specifically designed and sent to Mars, at great expense to the US taxpayers, to find water on Mars. The reason? People want to know “whether water was ever around long enough to provide a habitat for life”. (See MRO overview). However, finding water on Mars, Europa, or anywhere else, will not prove there was ever life anywhere else at all.
Repetition is a necessity for such a wilfully ignorant scientism community. The assumption that finding water means finding life is based exclusively on the evolutionary assumption that life is just chemistry and will happen anywhere conditions are right, without any outside intelligent intervention. Life on earth certainly does require liquid water, but the presence of water will not make life, irrespective of what chemicals may be in it. Life requires outside information that is only known to have come from the mind of the Creator Christ. Water and chemicals will not produce information out of nothing, even though Jesus did!
Furthermore, the Creator of life has told us His purpose for the objects we see in the sky – they are to serve mankind as signs, times and seasons (Genesis 1:14-15) and to declare the glory of God (Psalm 19). Therefore, it is appropriate for us to study them and learn from them, so we can give praise to the Creator, whose power and greatness are displayed in the sky every night for all to see.
