If you’ve been a longtime reader of my blog, you may remember, In 2015 NASA scientists have confidently announced that they have discovered the existence of a stream of water flowing on Mars. Soon after, scientists speculated that since water had been found on Mars, life might have been found there. But researchers at the US Geographical Survey, another US agency, poured cold water on all these speculations.

According to them, the flow claimed by NASA is not actually water, but they have flowing dry sand. Scientists have been increasingly optimistic about the presence of water on Mars since 2011 when NASA’s Mars Reconnaissance Orbiter (MRO) spacecraft sent images of some grooves that looked like water flowing to Earth. Extremely cold weather on Mars caused those grooves to change with the changing seasons, which led NASA scientists to become optimistic about the existence of water on Mars and the existence of life in that water. But scientists at the U.S. Geographical Survey say they have noticed features in the grooves that aren’t actually in the water flow, but are more likely to be dry sand and dust streams.

At first glance, they may seem watery, as the currents descend from the steep slopes of Mars’ mountains. But new research suggests that these currents only flow from steep slopes of 28 degrees or more, but are not seen on relatively low slopes, although the latter feature is somewhat distorted when it comes to water flow. And after analyzing more than one and a half hundred such lines, now the scientists of USGS have come up with the idea Doing The potential for water in those streams is very low – at least less than NASA’s previous strong claim.

However, scientists are not giving up here. They speculate that there may be water in some other part of Mars. And from that, aliens can also be found there. None of this is just an idea so far. On this site to learn about the next discovery By subscribing Stay with me!
