Rover NASA «Opportunity" for almost a month did not get in touch
Rover "Opportunity" space agency NASA is still a "silent" as to cover the entire planet Mars dust storm and did not think to end. Recall that the storm began back on May 30. A few weeks later the storm covered almost the entire planet. The Mars air is now contained a quantity of dust that the sunlight that feeds on "Opportunity", can not reach its solar panels. Marskhod itself is in hibernation mode.
"We do not receive any signals from the rover for the past several weeks," - said Ray Arvidson of Washington University in St. Louis. Arvidson is the first deputy head of the scientific mission Mars Exploration Rover, under the auspices of which two twin rover-work - "Opportunity" and "Spirit." Both rovers with a break of a few weeks, landed in different areas of the Red Planet.
After a long silence, "Spirit" was released on bond in 2009, saying that was stuck in a sand dune. March 22, 2010, he finally broke down. His twin brother "Opportunity" to the present day was in working order and continued to perform scientific tasks. Last time the rover sent photos from the surface of Mars on 10 June. Since then about it or hearing, nor spirit.
Currently, the rover is likely is in the low power consumption mode. His computer wakes up from time to time, check the amount of energy coming from solar panels, and if it turns out to be low, again "go to sleep", shared Arvidson portal Inside Outer Space.
The graph shows the ratio available for the rover "Opportunity" amount of energy (in watts / hour, marked yellow) and the level of transparency / opacity of the atmosphere of the planet (parameter indicated in tau, in blue)
"At some point, when the storm recede," Opportunity "should wake up and decide whether it is enough energy for signal transmission via antenna with low gain. This will happen within a few Sols (martian days, lasting about 40 minutes longer than the earth) until it ultimately will not solve reach the full level of efficiency, "- said Arvidson.
"We continue to listen to, but as long as the transmitter of the rover's no news. Yes, this storm continues to rage with full force. "
"The storm covered the entire planet, and its power continues to grow. However, I remain confident that we will be able to survive it ", - said Jim Rice of Arizona State University, head of the group astrogeology Mars Exploration Rover project.
