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.

Asked if I was gay, hit on head when I didn't respond: B'luru man assaulted in restaurant washroom
Bengaluru: A 23-year-old executive from a private company was allegedly assaulted by an individual at a restaurant in Bengaluru’s Ashoknagar following a minor disagreement.
The man, a resident of Cox Town, alleged that he was assaulted by an unknown person in the restaurant's washroom around 11:00 PM last week, as reported by Deccan Herald on Saturday.
He visited the restaurant with two friends and went to the washroom after the meal.
The man told the police that an unknown individual asked him if he was gay, but he chose not to respond, as mentioned by DH. “He kept asking me. He asked me again when I was heading out and hit me on my head when I didn’t answer,” the man said.
His friend contacted the police helpline, but by the time they arrived, the suspect had already fled, as per the FIR filed with the Cubbon Park police.
The police are currently searching for the individual responsible for the alleged assault. An FIR has been lodged under BNS sections 126(2) (wrongful restraint) and 115(2) (voluntarily causing hurt).
