Spectacular Martian cloud formation through this small camera
It is known as VMC (Visual Monitoring Camera), and its objective was simply to monitor the separation of the Beagle 2 of the Mars Express and nothing more. Once his goal, which allowed him to see that surface probe for the last time before it disappeared in the drama of a failed landing, was disconnected. But not by much, since it soon became clear that having an operational camera, however limited, and letting it sleep forever was a waste. And so was born the one that is popularly known as Mars Webcam, which for years, and on a daily basis, It publishes images that are perhaps not very useful from a scientific point of view but are of tremendous value when it comes to popularizing space exploration.
Your images, like a terrestrial webcam, offer us the possibility to look Mars almost in real time, and there are few who scrutinize all of them in search of strange elements. And recently the Mars Webcam It was in the spotlight in many forums and social networks, because through it could be seen the appearance of a strange cloud formation that seemed to originate in one of the volcanoes of Mars. The first impression, and so the rumor spread, is that perhaps we were witnessing the awakening of one of those colossi, apparently extinct although indications that not so much of his last awakening.
The explanation, which comes from the hand of Tanya Harrison, director of research at the ASU News Space at the University of Arizona, is less spectacular, although more consistent with what we know about Mars:"These are clouds of water ice that condense on the summit of Arsia Mons, one of the great volcanoes of Mars. They are very common in Arsia at this time of year, from late southern hemisphere to summer" These are born as a result of what can be called "orographic effect", the movement of air currents around this mass of 21 kilometers in height, which causes the condensation of water vapor that is present in the atmosphere at this time of the year. year. In the land we can also see similar things although not so spectacular.
Beyond its nature, perhaps the most striking thing is that a camera as simple and limited as VMC, doing now a task for which it was not originally designed, is capable of revealing such curious details, as well as getting so many people really interested in the exploration of the red planet. Unlike most terrestrial webcams, that of the Mars Express, the most distant active, really makes a difference in positive.

This is how the VMC (Visual Monitoring Camera), the furthest webcam in the world, created with a unique purpose, sees the departure of Beagle 2, but now it is an essential part of the Mars Express probe.
The Beagle 2 moving away and captured by the VMC. That was his goal and after this moment he would be disconnected, although only temporarily. It would return converted into the Mars Webcam.
The first look of the VMC after being awakened after 3 years disconnected. Although it was not correctly oriented and we can only see Mars lean out a bit on the right, it showed that the long sleep had not affected her and she was ready to return to the activity.
Since his return he is one of the stars of the Mars Express, especially because it is an instrument open to the public, so it helped more than any other activity of the probe in bringing it closer to the people on the street.
There is not a volcanic eruption on Mars: they are clouds
