yes it is...?

not really, these dark lines were identified like five years ago or something and flowing water has been number one explanation ever since. > NASA Spacecraft Data Suggest Water Flowing on Mars > 08.04.11 http://www.nasa.gov/mission_pages/MRO/news/mro20110804.html http://www.nasa.gov/mission_pages/MRO/news/mro20110804.html

  First three links and fifth are all talking about ice, not liquid flowing water. Fourth link isn't conclusive These results are the closest scientists have come to finding evidence of liquid water on the planet's surface today. The last link summarises that liquid water has not been conclusively found yet, and it is the most recent: While recent orbiter missions have confirmed the presence of subsurface ice, and melting ground-ice is believed to have formed some geomorphologic features on Mars, this study used meteorites of different ages to show that significant ground water-ice may have existed relatively intact over time. Curiosity’s observations in a lakebed, in an area called Mount Sharp, indicate Mars lost its water in a gradual process over a significant period of time. So none of your links contradict what the person you are replying to said.
