No, not that kind of streaking.
Streaks appear running down slopes on Mars, in the mid-latitude and now in the equatorial regions. They appear seasonally, in the warmest parts of the Martian year. Some scientists think the streaks are caused by flowing salt water-- salt water stays liquid at lower temperatures than fresh water-- or brine.
If it is water, it suggests there's a lot more water near the surface than previously thought. That would alter the picture for possible past life on Mars, extant life, and possible future human colonization.
