NASA spots silent Opportunity rover on Mars
Washington, Sep 26 : A NASA Mars orbiter has spotted the agency's Opportunity rover on the Red Planet for the first time since it went into hibernation after a dust storm swept over the region a little more than 100 days ago and blocked sunlight from reaching the rover.
A high-resolution camera aboard NASA's Mars Reconnaissance Orbiter (MRO) captured the image of the rover on the slopes of the Red Planet's Perseverance Valley, NASA said in a statement on Tuesday.
But the future of Opportunity is still in limbo as NASA has still not heard from the 14-year-old solar-powered rover. The image of the rover, taken on September 20, was produced from about 267 kilometres above the Martian surface.
The image showed that the dust storm over Perseverance Valley has substantially cleared.
NASA scientists estimated that the tau -- a measurement of how much sunlight reaches the surface -- over Opportunity to be a little higher than 10 during some points during the dust storm.
The higher the tau, the less sunlight is available.
The tau has steadily fallen in the last several months. On September 20, tau was estimated to be about 1.3 by MRO's Mars Color Imager camera.
According to scientists at NASA's Jet Propulsion Laboratory in California, Opportunity will need a tau of less than 2.0 before the solar-powered rover will be able to recharge its batteries.
No signal from Opportunity has been heard since june 10.
In an attempt to talk to the rover, the Opportunity team is increasing the frequency of commands it beams to the rover via the dishes of NASA's Deep Space Network from three times a week to multiple times per day.

England sticking with Key, McCullum and Stokes despite Ashes humbling
London (AP): England is not sacking anybody following the 4-1 Ashes loss in Australia.
A review of the tour by the England and Wales Cricket Board, announced within hours of the final match in January, was concluded on Monday. Firing people would “be the easy thing to do,” ECB chief executive Richard Gould said but he insisted, "This is not the time to throw everything out."
Managing director Rob Key, coach Brendon McCullum and captain Ben Stokes kept their jobs after the best England side to go to Australia in 14 years lost the Ashes in 11 days with two games to spare.
“Moving people on can sometimes be the easy thing to do. That's not the route that we're going to take,” Gould said. “I've seen the driving ambition and determination that we're lucky enough to have within our leadership group to take the lessons from the Ashes and move forward.”
Gould previously was the chief executive of Bristol City soccer club and said the ECB would not follow the same route as soccer's hire-and-fire culture.
“Cricket is a very unique sport in that it takes a team of leadership ... it's not like football where there's a single point of failure or success with a manager," he said. He added the ECB would not “select or deselect management based on a popularity campaign.”
The main criticisms of England's tour were poor preparation, player misbehavior, and selection mistakes.
At a press conference at Lord's, Gould and Key said McCullum and Stokes have not had a “bust up,” they did not want McCullum to “completely change” but “to evolve,” the behavior of some players was “unprofessional,” there will be more consequences for underperforming, and a commitment to “better long-term planning” ahead of major test series.
Some changes were already implemented for the Twenty20 World Cup, where England reached the semifinals. Gould implied that performance saved McCullum.
Key acknowledged that England supporters would be disappointed to see the management team go unpunished.
“I know people want punishment and that people then should be sacked for that,” Key said. “That doesn't mean we don't feel like we've gone through some serious pain: Brendon, myself, Ben. It's been as tough a time as I think I've had.”
