The remote possibility of remoteness on Mars is still in awe



When we remember officially deadly Opportunity this week, one fact still seems to me: this machine has gone a huge 28 miles across the surface of another planet. And it did so in short, irritable nerves. Spread over 14 years, the 28 miles may not sound so much, but think of the many obstacles Oppy faces, including the tough 38 days that are spinning in a soft sand dune.

kilometers) on the Martian surface. This is more than the distance traversed by the Apollo lunar revolver (22.2 miles), the Soviet Lunar 2 (24 miles), the Twentieth Mile (12.3 miles), or the Opportunity partner from Spirit Spirit (4.8 miles). Enormous plains, sand dunes and craters are photographed along the way – and found evidence of the Red Planet's water.

Opi's impressive march

If Oppy started sliding to a rock, for example, engineers would not be able to send commands to stop it until it was too late. So they need to send commands to move a short distance, retrieve new data, reassess and then send new commands. As NASA describes on the information page, the movement of Oppy is a tricky process. Rover and his team overcame many technical failures related to management, heaters and built-in memory. Magic dust storms threatened Rover, covering solar panels with debris and depriving him of the energy source. Probably the best example of the challenges Opi faced was the 38 days of Mars, who were in the dune, unable to get the thrust needed to push the soft sand. After carefully planned wheel rotation more than 629 feet, the team finally managed to push the Rover and continue its journey ahead.

After all, what finally broke the rivers was not a sand dune, but a massive Martian dust. storm. However, the mission was a wild success that revolutionized our understanding of Mars. During their long journeys, Opportunity shot a wide variety of strange and wonderful images on the Red Planet.
