The mouth of a dry river on Mars

27 Mar

Mars RiverAutomatic station Mars Reconnaissance Orbiter has made a picture of the fan on the side of the crater on Mars formed, according to geophysicists, once the existing water flows in the river mouth. This was reported on the website of NASA.

Picture taken January 23, 2016 with the help of the camera High Resolution Imaging Science Experiment Mars Reconnaissance Orbiter station.

This image, scientists plan to use to determine the dynamics that existed in the past, the river systems of the planet. According to scientists, the removal of the cone in the crater is one of the best preserved on Mars.

September 28, 2015, NASA announced that the world found the river – seasonally appearing flows of salty liquid water. Thanks to some hydrated salts water remains liquid at temperatures of minus 70 degrees Celsius. Previously, scientists have detected on Mars, however, the hydrated form – for the first time.

Alluvial fan is a kind of relief, formed by streams of water in the world in the area of ​​estuaries or temporary streams. The characteristic structure and has the shape of half-cone is formed from the debris resulting from changes river flow rate.

At the moment five stations are located in the orbit of Mars. Three of them – the US: Mars Odyssey (2001), Mars Reconnaissance Orbiter and the MAVEN . On the surface of the Red Planet are American rovers Opportunity (2004) and Curiosity . Rover Opportunity – record for uptime and machine Curiosity – the most difficult planetary rovers (its weight – 900 kg). To Mars sent to Russian-European station Exo Mars-2019 includes the orbiter TGO (Trace Gas Orbiter) and landing demonstration module Schiaparelli. The station is to reach the Red Planet in the middle of October 2016.
