Mars Rover Curiosity Completes First Full Drill

For the first time in history, humans have drilled a hole into rock on Mars and are collecting the powdered results for analysis, NASA announced Saturday.

After weeks of intensive planning, the Mars rover Curiosity undertook its first full drill on Friday, with NASA receiving images on Saturday showing that the procedure was a success.

Curiosity drilled a hole that is a modest 2.5 inches (6.35 centimeters) deep and .6 inches (1.52 centimeters) wide but that holds the promise of potentially great discoveries. (Watch video of the Mars rover Curiosity.)

"The most advanced planetary robot ever designed now is a fully operating analytical laboratory on Mars," John Grunsfeld, NASA associate administrator for the agency's Science Mission Directorate, said in a statement on Saturday.

"This is the biggest milestone accomplishment for the Curiosity team since the sky-crane landing last August."

The site of the much-anticipated penetration is a flat section of Mars rock that shows signs of having been underwater in its past.

Called Yellowknife Bay, it's the kind of environment where organic materials—the building block of life—might have been deposited and preserved long ago, at a time when Mars was far wetter and warmer than it is today.

The contents of the drilling are now being transferred into the rover's internal collection system, where the samples will be sieved down to size and scoured to minimize the presence of contamination from Earth. (Watch video of Curiosity's "Seven Minutes of Terror.")

Then the sample will be distributed to the two instruments most capable of determining what the rocks contain.

The first is the Sample Analysis on Mars (SAM), which has two ovens that can heat the powdered rock to almost 2000°F (1093°C) and release the rock's elements and compounds in a gaseous form.

The gases will then be analyzed by instruments that can identify precisely what they are, and when they might have been deposited. Scientists are looking for carbon-based organics believed to be essential for any potentially past life on Mars.

Powder will also go to the Chemistry and Mineralogy (CheMin) instrument for a related analysis that looks especially at the presence of minerals—especially those that can only be formed in the presence of water.

Louise Jandura, chief engineer for Curiosity's sample system at NASA's Jet Propulsion Laboratory, said that designing and testing a drill that can grab hold of Martian rock and commence first a percussive shallow drilling and then dig a deeper hole was difficult.

The drill, which is at the end of a 7-foot arm, is capable of about 100 discrete maneuvers.

"To get to the point of making this hole in a rock on Mars, we made eight drills and bored more than 1,200 holes in 20 types of rock on Earth," Jandura said in a statement.

Results from the SAM and CheMin analyses are not expected for several days to weeks.

After Blizzard, Northeast Begins to Dig Out

The Northeast began the arduous process of cleaning up after a fierce storm swept through the region leaving behind up to three feet of snow in some areas.

By early this morning, 650,000 homes and businesses were without power and at least five deaths were being blamed on the storm: three in Canada, one in New York and one in Connecticut, The Associated Press reported.

The storm dumped snow from New Jersey to Maine, affecting more than 25 million people, with more than two feet falling in areas of Massachusetts, Rhode Island and New Hampshire. The Postal Service closed post offices and suspended mail delivery today in New England.

As the storm waned, officials in the hardest hit areas cautioned residents to remain indoors and off the roads to ease the clean-up.

Massachusetts was hard hit by the storm, with more than two feet of snow in Boston and even more in coastal areas. State police and national guard troops helped rescue more than 50 stranded motorists and even helped deliver a baby girl, according to Massachusetts Gov. Deval Patrick.

Patrick enacted the first statewide driving ban since the 1978 blizzard, which left 27 inches of snow and killed dozens. The ban was to be lifted at 4 p.m. today, the governor said.

However, Patrick cautioned residents to act with extreme caution even after the ban is over.

"Stay inside and be patient," Patrick said.

In Massachusetts a boy reportedly died of carbon monoxide poisoning as he helped his father shovel snow on Saturday, according to ABCNews.com affiliate WCVB-TV in Boston.

For residents along the coast, the waning snowfall didn't mean the end of the storm. Storm surges along the Massachusetts coastline forced some residents out of their homes Saturday morning.

"We've got 20-foot waves crashing and flooding some homes," Bob Connors on Plum Island told WCVB. "We have power and heat and all that. We just have a very angry ocean. In my 33 years, I've never seen the seas this high."

In Connecticut, Gov. Dannel Malloy declared a state of emergency and closed all roads in the state. The state police responded to more than 1,600 calls over the last 24 hours and the governor called up an additional 270 National Guard members.

"If you're not an emergency personnel that's required to be somewhere, stay home," Malloy said.

Overnight, snow fell at a rate of up to five to six inches per hour in parts of Connecticut. In Milford, more than 38 inches of snow had fallen by this morning.

In Fairfield, Conn. firefighters and police officers on the day shift were unable to make it to work, so the overnight shift remained on duty.

The wind and snow started affecting the region during the Friday night commute.

In Cumberland, Maine, the conditions led to a 19-car pile-up and in New York, hundreds of commuters were stranded on the snowy Long Island Expressway. Police and firefighters were still working to free motorists early this morning.

"The biggest problem that we're having is that people are not staying on the main portion or the middle section of the roadway and veering to the shoulders, which are not plowed," said Lt. Daniel Meyer from the Suffolk County Police Highway Patrol.

In New York, authorities are digging out hundreds of cars that got stuck overnight on the Long Island Expressway.

Bob Griffith of Syosset, N.Y., said he tried leave early to escape the storm, but instead ended up stuck in the snow by the side of the road.

"I tried to play it smart in that I started early in the day, when it was raining," said Griffith. "But the weather beat us to the punch."

Suffolk County Executive Steven Bellone said the snow had wreaked havoc on the roadways.

"I saw state plows stuck on the side of the road. I've never seen anything like this before," Bellone said.

However, some New York residents, who survived the wrath of Hurricane Sandy, were rattled by having to face another large and potentially dangerous storm system with hurricane force winds and flooding.

"How many storms of the century can you have in six months?" said Larry Racioppo, a resident of the hard hit Rockaway neighborhood in Queens, New York.

In New York, a little more than 11 inches fell in the city.

By this morning, New York Mayor Michael Bloomberg said nearly all of the primary roads had been plowed and the department of sanitation anticipated that all roads would be plowed by the end of the day.

"It looks like we dodged a bullet, but keep in mind winter is not over," said Bloomberg.

Data-wiping algorithm cleans your cellphone

Paul Marks, chief technology correspondent

Mailing your cellphone to a recycling company might make you a few pounds, but it can leave you at risk of identity theft. The deletion techniques recycling companies use are meant for hard discs, and so don't work on the solid-state flash memory used in mobile phones. That means personal data like banking info, texts, contacts and pictures can end up in the hands of, well, anyone the phone ends up with.  

To remedy the problem, British company BlackBelt Smartphone Defence of Skelmersdale, Lancashire claims to have developed a software algorithm that can securely delete data on cellphone memory chips. The trouble with data in a flash memory chip is that it is protected by an on-chip protection algorithm called the wear leveller. This hard-coded routine does its best to ensure the chip's lifetime is maximised so that each memory cell's ability to store charge is not worn out.

"The problem is that the wear-levelling algorithm ends up working
against the data wiping technique used for hard drives, which tries to
overwrite all the data,"
says the company's Ken Garner.

What the firm has done is write their own algorithm, called BlackBelt DataWipe, that works with,
rather than against, the leveller routine to render data
irrecoverable. "It is like having a shredder for personally identifiable
data," says Garner.

However, they don't yet know if their method is proof against sophisticated, nation-state level attacks - which might use electron microscopes
to read the last vestiges of the zeros and ones on a memory chip. "I imagine
if you're GCHQ you'll probably have technology that could get around
this and recover it in some way," says Garner.

Blizzard brings US northeast to a halt

NEW YORK: Planes, cars and trains came to a standstill across the densely populated US northeast Friday in the face of a blizzard raging from New York to Boston.

The storm was forecast to bring the heaviest snow so far this winter along the New England coast, threatening power and transport links for tens of millions of people.

By late Friday, New York, one of the world's busiest air travel hubs, was cut off from the skies as snow and wind led airlines to suspend all operations at LaGuardia, Newark Liberty and John F Kennedy International airports.

Tom Bosco, general manager of LaGuardia, told NY1 television that the airport was "battling" the storm and would strive to remain open even after the airlines shut down for the night.

He estimated that if a foot of snow fell -- the worst case scenario forecasted for New York -- flights would resume "probably by mid-morning."

The heaviest impact of the storm was expected overnight in and around Boston, and Governor Deval Patrick temporarily ordered all normal traffic off Massachusetts roads, with the threat of up to a year in jail for violators.

"There are a number of exemptions for... emergency workers and the like. Please exercise caution and use common sense," Patrick said at his emergency centre in Framingham.

In Connecticut, Governor Dannel Malloy issued a "ban on motor vehicle travel on limited access highways" to free up emergency services traffic.

Rhode Island, where some of America's most exclusive summer homes are located, also instituted driving restrictions.

In addition to the road and air snarl-ups, the rail service Amtrak said trains from New York northbound and also to the capital Washington, DC, were being suspended.

The storm came a little over three months after Hurricane Sandy devastated swathes of New York and New Jersey, killing 132 people and causing damage worth some $71.4 billion.

Snow began in light flurries across the region early Friday, but thickened and by Saturday was expected to leave depths of between half and one foot in New York and as much as two feet in Boston.

The National Weather Service warned that "in addition to the heavy snowfall, wind gusts of up to hurricane force are possible, especially near the coast. This will result in blizzard conditions with drifting and blowing snow."

On Friday night travel "will be extremely hazardous, if not impossible," the National Weather Service said.

Among the more glamorous victims of the travel upsets was designer Marc Jacobs, who said he had to reschedule his two shows at New York Fashion Week due to "the snow storm in the US and production problems."

New York Mayor Michael Bloomberg, who came under withering criticism for the city's flat-footed response to a blizzard in 2010, said residents should stock up with vital supplies and prepare for the worst.

"Stay off the city streets, stay out of your cars," he said at a news conference. "Staying off the streets will make it easier for city workers to clear the streets of snow."

New York's four zoos also announced they were closing for the duration of the storm.

"You can't take nature too lightly. Hopefully it won't be anything too drastic," Bloomberg said.

The good news was that the storm's peak was due as the weekend began, meaning far fewer people would be on the roads. Forecasters said the system should blow through on Saturday, with milder temperatures to follow.

Locals were comparing the coming storm to the ferocious Blizzard of 1978, which killed 100 people and buried Boston in more than 27 inches (68 centimetres) of snow and Providence, Rhode Island in nearly 28 inches (71 centimetres).

During that storm, people were forced to abandon cars stuck on highways and made their way around Boston on cross-country skis and snowshoes.

Faber)

Dining can be a delicate thing. Finding the right balance of flavors and ingredients can be tricky, but the meal is only half the story. Surrounding whatever food is on the plate, of course, is the environment. The setting could be anything from the soft glow of a candlelight dinner to the bright glare of a midday meal. Or, it could be any number of options dialed up from the range hood. Yes, that oft-overlooked thing above the stovetop.

The color of meal-making can now be controlled with the Arkea range hood made by the European firm Faber. The striking hood makes a big first impression with its stark, spherical design. However, it's when the lights go dim that the kitchen accessory really shines. Hidden inside, there lies a series of LEDs capable of illuminating the kitchen in the lighting scheme of your choice.

From energetic red to cool violet (as well as what lies between), the kitchen hood is designed to make an impression. It's not fearful of utility, however; the range hood makes sure it can get the job done, no matter the presentation. Featuring operation via remote control, the range hood can be raised or lowered at the press of a button. In addition to its ability to vent steam and smoke away from the stovetop, the hood features four white spotlights to illuminate the actual cooking area. No matter what happens to end up on the plate, with the range hood's combination of style and functionality, it will certainly form a complete meal.

From Our Vault: Busy Postman on Break, 1951

The United States Post Office announced this week that it intends to stop Saturday letter delivery beginning in August, 32 years after Congress mandated a sixth day of mail service.

First class mail volume has been dropping by about five billion pieces annually since 2007. And the USPS operated almost $16 billion dollars in the red in 2012.

In the 1950s, when this photo was taken, the federal agency was more flush with money. Five hundred thousand employees carried 54 billion items when National Geographic magazine published the article "Everyone's Servant, the Post Office" in July of 1954. Mail volume had doubled since the previous decade, and was growing at a rate of about seven percent a year.

This photo from 1951 didn't make it into that article, landing instead in the National Geographic image archive. Working during the postal boom years, this mailman delivering to houses in Hays, Kansas, likely didn't have time to notice the slight.

National Geographic photographer John E. Fletcher explained the mailman's decision to lunch in a mailbox in a note on the back of the photo.

"He told me that a new regulation from the Washington headquarters of the U.S. Post Office required that postmen while on delivery at noontime must stop and have their lunch at the spot, rather than taking time off to go home and eat," Fletcher wrote.

"This mailman told me that each day his wife would drive to this particular corner and meet him and hand him his lunch box," he continued. "The most convenient spot that he could find to eat his lunch was to open a storage mail box, get himself comfortably seated, and eat his lunch right on the street corner."

Editor's note: This is the first in a series of pieces that looks at the news through the lens of the National Geographic photo archives.

'Stay Home': Northeast Shuts Down as Blizzard Hits

A blizzard of possibly historic proportions is set to strike the Northeast, starting today and could bring more than two feet of snow and strong winds that could shut down densely populated cities such as Boston and New York City.

A storm from the west will join forces with one from the south to form a nor'easter that will sit and spin just off the East Coast, affecting more than 43 million Americans. Wind gusts will reach 50 to 60 mph from Philadelphia to Boston.

"[It] could definitely be a historic winter storm for the Northeast," Adrienne Leptich of the National Weather Service in Upton, N.Y., said. "We're looking at very strong wind and heavy snow and we're also looking for some coastal flooding."

The snow began falling in New York City shortly before 7 a.m. ET. The snow is expected to mix with some sleet and then turn back into snow after 3 p.m.

Airlines have started shutting down operations between 2 p.m. and 5 p.m. at major airports in the New York area as well as in Boston, Portland, Maine, Providence, and other Northeastern airports. More than 4,000 flights have been cancelled on Friday and Saturday, according to FlightAware. Airlines hope to resume flights by Saturday afternoon.

New York City is expecting up to 14 inches, which is expected to start this morning with the heaviest amounts falling at night and into Saturday. Wind gusts of 55 mph are expected in New York City and Cape Cod, Mass., could possibly see 75 mph gusts.

Winter Storm to Hit Northeast With Winds and Snow Watch Video

Boston, Providence, R.I., Hartford, Conn., and other New England cities canceled school today. Boston and other parts of New England could see more than 2 feet of snow by Saturday.

Massachusetts Governor Deval Patrick declared a state of emergency Friday afternoon and announced a ban on all traffic from roads after 4 p.m. It is believed that the last time the state enacted such a ban was during the blizzard of 1978.

Beach erosion and coastal flooding is possible from New Jersey to Long Island, N.Y., and into New England coastal areas. Some waves off the coast could reach more than 20 feet.

"Stay off the streets of our city. Basically, stay home," Boston Mayor Tom Menino warned Thursday.

Blizzard warnings were posted for parts of New Jersey and New York's Long Island, as well as portions of Massachusetts, Rhode Island and Connecticut, including Hartford, New Haven, Conn., and Providence. The warnings extended into New Hampshire and Maine.

To the south, Philadelphia was looking at a possible 4 to 6 inches of snow.

Thousands of flights have already been canceled in anticipation of the storm. Amtrak said its Northeast trains will stop running this afternoon.

Bruce Sullivan of the National Weather Service says travel conditions will deteriorate fairly rapidly Friday night.

"The real concern here is there's going to be a lot of strong winds with this system and it's going to cause considerable blowing and drifting of snow," he said.

Parts of New York, still reeling from October's Superstorm Sandy, are still using tents and are worried how they will deal with the nor'easter.

"Hopefully, we can supply them with enough hot food to get them through before the storm starts," Staten Island hub coordinator Donna Graziano said.

New York City Mayor Michael Bloomberg said plows and 250,000 tons of salt were being put on standby.

"We hope forecasts are exaggerating the amount of snow, but you never can tell," Bloomberg said Thursday.

Residents of the Northeast have already begun to hit stores for groceries and tools to fight the mounting snow totals.

The fire department was called in to a grocery store in Salem, Mass., because there were too many people in the store Thursday afternoon trying to load up their carts with essential items.

"I'm going to try this roof melt stuff for the first time," Ian Watson of Belmont, Mass., said. "Just to prevent the ice dam. ... It's going be ugly on that roof."

ABC News' Max Golembo and The Associated Press contributed to this report.

Robot inquisition keeps witnesses on the right track

MEMORY is a strange thing. Just using the verb "smash" in a question about a car crash instead of "bump" or "hit" causes witnesses to remember higher speeds and more serious damage. Known as the misinformation effect, it is a serious problem for police trying to gather accurate accounts of a potential crime. There's a way around it, however: get a robot to ask the questions.

Cindy Bethel at Mississippi State University in Starkville and her team showed 100 "witnesses" a slide show in which a man steals money and a calculator from a drawer, under the pretext of fixing a chair. The witnesses were then split into four groups and asked about what they had seen, either by a person or by a small NAO robot, controlled in a Wizard of Oz set-up by an unseen human.

Two groups - one with a human and one a robot interviewer - were asked identical questions that introduced false information about the crime, mentioning objects that were not in the scene, then asking about them later. When posed by humans, the questions caused the witnesses' recall accuracy to drop by 40 per cent - compared with those that did not receive misinformation - as they remembered objects that were never there. But misinformation presented by the NAO robot didn't have an effect.

"It was a very big surprise," says Bethel. "They just were not affected by what the robot was saying. The scripts were identical. We even told the human interviewers to be as robotic as possible." The results will be presented at the Human-Robot Interaction conference in Tokyo next month.

Bilge Mutlu, director of the Human-Computer Interaction Laboratory at the University of Wisconsin-Madison, suggests that robots may avoid triggering the misinformation effect simply because we are not familiar with them and so do not pick up on behavioural cues, which we do with people. "We have good, strong mental models of humans, but we don't have good models of robots," he says.

The misinformation effect doesn't only effect adults; children are particularly susceptible, explains the psychologist on the project, Deborah Eakin. Bethel's ultimate goal is to use robots to help gather testimony from children, who tend to pick up on cues contained in questions. "It's a huge problem," Bethel says.

At the Starkville Police Department, a 10-minute drive from the university, officers want to use such a robotic interviewer to gather more reliable evidence from witnesses. The police work hard to avoid triggering the misinformation effect, says officer Mark Ballard, but even an investigator with the best intentions can let biases slip into the questions they ask a witness.

Children must usually be taken to a certified forensic child psychologist to be interviewed, something which can be difficult if the interviewer works in another jurisdiction. "You might eliminate that if you've got a robot that's certified for forensics investigations, and it's tough to argue that the robot brings any memories or theories with it from its background," says Ballard.

The study is "very interesting, very intriguing", says Selma Sabanovic, a roboticist at Indiana University. She is interested to see what happens as Bethel repeats the experiment with different robot shapes and sizes. She also poses a slightly darker question: "How would you design a robot to elicit the kind of information you want?"

This article appeared in print under the headline "The robot inquisition"

It's all about how you say it

When providing new information, rather than helping people recall events (see main story), a robot's rhetoric and body language can make a big difference to how well it gets its message across.

Bilge Mutlu of the University of Wisconsin-Madison had two robots compete to guide humans through a virtual city. He found that the robot which used rhetorical language drew more people to follow it. For example, the robot saying "this zoo will teach you about different parts of the world" did less well than one saying "visiting this zoo feels like travelling the world, without buying a plane ticket". The work will be presented at the Human-Robot Interaction conference in Tokyo next month.

Microsoft wins latest round in Motorola patent case

SAN FRANCISCO: A federal judge on Thursday tossed out more than a dozen patent infringement claims filed against Microsoft by Google-owned Motorola Mobility.

US District Court Judge James Robart, in Microsoft's home state of Washington, sided with the software colossus, dismissing 13 claims of infringement on a trio of Motorola patents involving digital video encoding and decoding, according to court records.

The Motorola patents were evidently not specific enough regarding the computer code involved, according to the documents.

The decision significantly narrowed the case.

If the remaining claims survive a similar legal challenge, Microsoft would likely be entitled to pay a reasonable rate to license what is considered a "standards-essential" technology, according to intellectual property specialist Florian Mueller, of FossPatents.com.

FAA approves Boeing test flights of grounded 787 Dreamliner

The first Boeing 787 Dreamliner takes off on its initial flight in 2009.

Daniel Terdiman/CNET)

Boeing was granted permission today to conduct test flights of its 787 Dreamliner as the aircraft maker tries to determine the cause of battery fires that have kept the fleet of planes grounded around the world.

The test flights will be subject to a number of restrictions, the Federal Aviation Administration said today, including limiting the flights to specific airspace over unpopulated areas. Other conditions include pre-flight testing and inspections, and in-flight monitoring.

"The traveling public's safety is our highest priority," the FAA said in a statement. "These test flights will be an important part of our efforts to ensure the safety of passengers and return these aircraft to service."

The Seattle-based aircraft builder said it hopes to resume flight test activities soon using its fifth flight test airplane, although it didn't say how many flights were planned.

"While our work to determine the cause of the recent battery incidents continues in coordination with appropriate regulatory authorities and investigation agencies, we are confident that 787 is safe to operate for this flight test activity," the company said in a statement. "As additional precautions, we have implemented additional operating practices for test flights, including a one-time preflight inspection of the batteries, monitoring of specific battery related status messages, and a recurring battery inspection."

The FAA ordered airlines to ground their fleets of the much-hyped Dreamliner last month after a series of fires involving the aircraft's lithium-ion batteries. The action came on the heels of Japanese carriers All Nippon Airways and Japan Airlines grounding their 787s after a battery fire forced the evacuation of an ANA flight.

A similar incident occurred January 7 when a JAL 787 on the ground at Boston's Logan International Airport caught fire. In response, the FAA announced it would conduct a comprehensive review of the aircraft, which features innovative use of composite materials.

The National Transportation Safety Board announced today it had traced the JAL battery fire to a single cell that short circuited and then spread to other cells. The safety board further said it will focus on the design and certification requirements of the battery system.

The NTSB said a Boeing risk assessment conducted during the plane's certification process found that the likelihood of a battery smoke emission event would occur on the 787 less than once in every 10 million flight hours.

Noting that there have already been two incidents in less than 100,000 flight hours, NTSB Chairman Deborah A.P. Hersman said in a statement that "the failure rate was higher than predicted as part of the certification process and the possibility that a short circuit in a single cell could propagate to adjacent cells and result in smoke and fire must be reconsidered."
