Optimistic about Mars Opportunity rover, says NASA
Washington, Aug 20 : There's reason to be optimistic about Mars Opportunity rover that has been silent since June 10, after getting caught in a massive dust storm on the Red Planet that cut off solar power for the nearly 15-year-old rover, NASA said in a statement.
According to the scientists, the global dust storm is "decaying" -- meaning more dust is falling out of the atmosphere than is being raised back into it. As a result, skies might soon clear enough for the solar-powered rover to recharge and attempt to "phone home."
Studies on the state of batteries and temperatures at the location showed that they were relatively in good health before the storm, and there is not likely to be too much degradation.
Moreover, because dust storms tend to warm the environment -- and the storm happened in summer -- the rover should have stayed warm enough to survive, the US space agency noted.
Engineers at NASA's Jet Propulsion Laboratory in California are now looking for signs for recovery efforts.
According to them, Opportunity will need a tau -- the veil of dust blowing around -- of less than 2.0 before the solar-powered rover will be able to recharge its batteries.
The higher the tau, the less sunlight is available; the last tau measured by Opportunity was 10.8 on June 10. To compare, an average tau for its location on Mars is usually 0.5.
Several times a week, the engineers are using NASA's Deep Space Network, which communicates between planetary probes and Earth, to attempt to talk with Opportunity.
The massive DSN antennas ping the rover during scheduled "wake-up" times, and then search for signals sent from Opportunity in response.
In addition, JPL's radio science group uses special equipment on DSN antennas that can detect a wider range of frequencies. Each day, they record any radio signal from Mars over most of the rover's daylight hours, then search the recordings for Opportunity's "voice."
However, even after the first time engineers hear from Opportunity, it would take time to fully recover, NASA said.

Delhi Police registers case in connection with doctored videos of Home Minister Amit Shah
New Delhi, Apr 28: The Delhi Police registered a case on Sunday after a complaint by the Ministry of Home Affairs in connection with the doctored videos of Union Home Minister Amit Shah being circulated on social media platforms, officials said.
The Special Cell has registered an FIR under various sections of the IPC and relevant provision of the IT Act, they said. Sources in the Special Cell said that now arrests are likely to follow across the country.
According to the complaint filed by Sinku Sharan Singh, DC, Indian Cybercrime Coordination Centre (I4C), some doctored videos are being circulated on social media with "the intent of creating disharmony among communities which is likely to affect public tranquility and public order."
According to the complainant, links from which the videos were shared were also attached for further action.
A copy of the FIR was also sent to the IFSO unit of the Delhi Cyber Police.
