Opportunity rover goes dark during Mars dust storm

"If the rover's computer determines that its batteries don't have enough charge, it will again put itself back to sleep", NASA officials said.
Engineers last received a transmission from the 15-year-old Opportunity on Sunday morning.
The storm is one of the most intense ever observed on the Red Planet. It survived a less severe dust stormin 2007. The main concern, he said, was that the rover would get too cold.
One complication, he said, is if the rover's power drops low enough that it can not operate an onboard clock. The doctors are telling you to give it time, and the vital signs are good.
We are concerned but we are hopeful that the storm will clear and the rover will be able to communicate with us.
Another NASA rover called Curiosity, which arrived on Mars in 2012, does not face the same level of threat from the storm, which was detected on May 30.
The dust storm's total area is big enough to cover North American and Russian Federation. Although the rover now steers with two wheels instead of four and one of its arm joints is a bit creaky, it's currently exploring Perseverance Valley, a feature carved into the rim of Endeavor Crater.
Operators at NASA's Jet Propulsion Laboratory (JPL) attempted to contact the rover on Tuesday but did not receive a signal, which means the craft has likely entered a "low power fault mode" wherein all systems, save a mission clock, are shut down.
UK PM Theresa May backs Trudeau after Trump attacks
But then Trump pulled out of a joint statement while citing "false statements " by Canada's prime minister, Justin Trudeau . He also attacked Trudeau's character, calling the Liberal Party leader meek, weak and dishonest.
Monitoring Opportunity's power levels will indicate how successfully the rover is able to balance a lower-than-normal battery charge with the need to keep heaters operating to offset the frigid temperatures. Dust storms reduce the rover's access to sunlight and therefore its ability to charge.
Jim Watzin, director of the Mars Exploration Program, said this attention to build quality is what has kept the Opportunity rover going so far past its 90-day mission forecast.
Scientists are not almost as concerned about the newer, nuclear-powered Curiosity rover on the other side of Mars, which is already seeing darkening skies.
"We're all pulling for Opportunity, it has been a remarkable rover", he said. The final frame, on the right, is a simulation based on the rover's data. The rover needs help from heaters to protect its batteries, much like running a vehicle in the winter to protect battery life.
Although the rover needs solar energy, it has about 8 watts of thermal energy available in its insulated box.
NASA is now listening constantly for any communication from the rover, but that won't happen until the storm clears. At most, it could endure for a month or two. Dust would be whipping around as Opportunity sits on the rusty ground, with all but its mission clock turned off, waiting for the storm to end. This storm, Zurek said, should die out before that landing, although there is a chance a second storm could later form. Engineers hope that the storm will provide some atmospheric shielding against the planet's dramatic daily temperature swings, Callas said.
A saving grace about these storms is that they limit the extreme temperature swings, and the dust they kick up can also absorb solar radiation, thus raising ambient temperatures around Opportunity.
The storms' cyclical nature, however, are poorly understood.
This partnership has yet to be formally announced by either company, but sources say that the announcement "could happen any day". This is an "interactive narrative story", an extension of the interactive videos that Netflix already has on its service .
Montopoli, speaking for the Canadian portion of the bid, said only that they had the government guarantees they had required. The two highest-ranked teams according to FIFA's rankings will receive byes, while the other four will play knockout games.
The two men are expected to meet on their own for the better part of an hour, with only a pair of interpreters in the room. That decision has raised concerns about the risk of holding such a monumental meeting with barely anyone to bear witness.
The software upgrades improve fuel consumption and emissions-neutral performance, and refines the automatic gear selection. The Brembo calipers are painted gold, peaking out from new lightweight wheels for the Volvo S60 Polestar Engineered .
The Fed has long aimed for 2 percent inflation, a level policymakers think is key to a healthy economy. United States stocks dropped slightly on the news, notes MarketWatch , and bond yields nudged higher.
The loss is Morocco's fifth in a World Cup bidding process after previous tries in 1994, 1998, 2006 and 2010. Trump tweeted his congratulations to those involved in winning the right to host the competition.

Suga, Japan's top government spokesman, welcomed the easing of tensions on the Korean Peninsula because of the Trump-Kim summit. Pompeo faced immediate questioning from his traveling press about the content of the agreement with North Korea.
His economic adviser then went on CNN to say that Trudeau had "stabbed Trump in the back" with his comments on tariffs. But, not surprisingly, the Twitterverse blew up with people curious about what De Niro had uttered.
