Mars rover "Opportunity" get out of Victoria Crater


NASA Opportunity rover has successfully climbed out of Victoria Crater, which it studied for nearly a year. Now he explores the area around the crater, studying rocks, hollowed out, believed to be from the surface of the powerful meteor strikes. Opportunity descended into the crater 800 meters wide in September 2007, after a study of its edges during the entire previous year.

The crater was deeper than any previously studied rover. Thus, scientists have studied the layers of rock in its walls to see how the geological conditions that shaped each subsequent layer, changed over time.

But about a month ago, there was a sharp spike voltage in the wiring of the left front wheel. A similar failure occurred in 2006 in the right-front wheel rover twin Spirit the day before the wheel stopped working.

Thus, the mission engineers prepared an escape route, deciding to withdraw the rover in the same way that he came into the crater. Scientists are concerned that any failure in the aging Mars rover could drive the rover to the crater trap.

Later Thursday, the rover has passed over the edge of the crater and out of the surrounding plain.

Now, Opportunity will study the stones scattered on the plain-stones the size of a fist. These stones seem to differ in color and composition from the sandstone, generated the first few hundred meters of the surface area of study.

According to the scientist Bruce Banerta sandstone tends to crumble into dust instead of forming such chunks of rock. According to him, these stones come from somewhere else. Some of them are likely to be meteorites, and some - the result of rock outcrops on the surface after heavy meteorite impacts.

After examining the rubble engineers who plan the rover’s next steps will be required to decide which job should be addressed as follows Opportunity.

If the rover, designed to work for about three months, but managed to work on Mars for more than four years, will be able to continue to properly perform the job, the team could send him to a huge crater, which is located 15 kilometers south of Victoria.
