A 2020 Rover Return to Mars?

NASA is so delighted with Curiosity's Mars mission that the agency wants to do it all again in 2020, with the possibility of identifying and storing some rocks for a future sample return to Earth.

The formal announcement, made at the American Geophysical Union's annual fall meeting, represents a triumph for the NASA Mars program, which had fallen on hard times due to steep budget cuts. But NASA associate administrator for science John Grunsfeld said that the agency has the funds to build and operate a second Curiosity-style rover, largely because it has a lot of spare parts and an engineering and science team that knows how to develop a follow-on expedition.

"The new science rover builds off the tremendous success from Curiosity and will have new instruments," Grunsfeld said. Curiosity II is projected to cost $1.5 billion—compared with the $2.5 billion price tag for the rover now on Mars—and will require congressional approval.

While the 2020 rover will have the same one-ton chassis as Curiosity—and could use the same sky crane technology involved in the "seven minutes of terror"—it will have different instruments and, many hope, the capacity to cache a Mars rock for later pickup and delivery to researchers on Earth. Curiosity and the other Mars rovers, satellites, and probes have garnered substantial knowledge about the Red Planet in recent decades, but planetary scientists say no Mars-based investigations can be nearly as instructive as studying a sample in person here on Earth.

Return to Sender

That's why "sample return" has topped several comprehensive reviews of what NASA should focus on for the next decade regarding Mars.

"There is absolutely no doubt that this rover has the capability to collect and cache a suite of magnificent samples," said astronomer Steven Squyres, with Cornell University in New York, who led a "decadal survey" of what scientists want to see happen in the field of planetary science in the years ahead. "We have a proven system now for landing a substantial payload on Mars, and that's what we need to enable sample return."

The decision about whether the second rover will be able to collect and "cache" a sample will be up to a "science definition team" that will meet in the years ahead to weigh the pros and cons of focusing the rover's activity on that task.  

As currently imagined, bringing a rock sample back to Earth would require three missions: one to select, pick up, and store the sample; a second to pick it up and fly it into a Mars orbit; and a third to take it from Mars back to Earth.

"A sample return would rely on all the Mars missions before it," said Scott Hubbard, formerly NASA's "Mars Czar," who is now at Stanford University. "Finding the right rocks from the right areas, and then being able to get there, involves science and technology we've learned over the decades."

Renewed Interest

Clearly, Curiosity's success has changed the thinking about Mars exploration, said Hubbard. He was a vocal critic of the Obama Administration's decision earlier this year to cut back on the Mars program as part of agency belt-tightening but now is "delighted" by this renewed initiative.

More than 50 million people watched NASA coverage of Curiosity's landing and cheered the rover's success, Hubbard said. If things had turned out differently with Curiosity, "we'd be having a very different conversation about the Mars program now."

If Congress gives the green light, the 2020 rover would be the only $1 billion-plus "flagship" mission—NASA's largest and most expensive class of projects—in the agency's planetary division in the next decade. There are many other less ambitious projects to other planets, asteroids, moons, and comets in the works, but none are flagships. That has left some planetary scientists not involved with Mars unhappy with NASA's heavy Martian focus.

Future Plans

While the announcement of the 2020 rover mission set the Mars community abuzz, NASA also outlined a series of smaller missions that will precede it. The MAVEN spacecraft, set to launch next year, will study the Martian atmosphere in unprecedented detail; a lander planned for 2018 will study the Red Planet's crust and interior; and NASA will renew its promise to participate in a European life-detection mission in 2018. NASA had signed an agreement in 2009 to partner with the European Space Agency on that mission but had to back out earlier this year because of budget constraints.

NASA said that a request for proposals would go out soon, soliciting ideas about science instruments that might be on the rover. And as for a sample return system, at this stage all that's required is the ability to identify good samples, collect them, and then store them inside the rover.

"They can wait there on Mars for some time as we figure out how to pick them up," Squyres said. "After all, they're rocks."

Bodies Found in Hunt for Missing Iowa Cousins

Nearly five months after Iowa cousins Lyric Cook and Elizabeth Collins disappeared, the girls' families have been told two bodies were found by hunters in a wooded area, though the identities of the bodies have not been confirmed, authorities said.

Capt. Rick Abben of the Black Hawk County Sheriff's Office said at a press conference this afternoon that the bodies are being transported to the state's medical office in Ankeny, Iowa, for positive identification.

"It's definitely not the outcome that we wanted, obviously," Abben said. "This is a difficult thing for us to go through."

Lyric, 11, and Elizabeth , 9, vanished shortly after noon on July 13 while on a bike ride in the small town of Evansdale, Iowa, triggering a massive search that brought the town to a standstill. The girls' bicycles and a purse were quickly found near Meyers Lake, but there was no sign of the girls.

On the two-month anniversary of the girls' disappearance, local residents held a prayer vigil and authorities urged members of the public to provide any new information that might help them solve the case.

Authorities said the girls left Elizabeth's house in Evansdale around 12:15 p.m., were spotted at approximately 12:23 p.m. at a nearby intersection and then were seen between 12:30 and 1 p.m. on a road by the lake.

During the following week, authorities canvassed the area and drained the town's lake. Lyric's estranged parents, Misty and Dan Morrissey, at one point became the subject of intense police scrutiny because of their criminal pasts and their lack of cooperation.

Over the summer, the families received a boost when Elizabeth Smart, one of the country's most famous kidnapping survivors, offered some words of encouragement. Police found Smart after a nine-month search in Utah a decade ago.

"For as many bad things that we hear about that happen, for as many kidnappings and terrible stories about finding the remains of children, why can't these girls be the exception?" Smart told the Des Moines Register.

Elizabeth's mother, Heather Collins, told ABC News' Alex Perez in July that the wait for the girls to reappear was an agonizing one.

"A day doesn't seem like a normal day," Collins said. "It's just like it doesn't stop. It keeps dragging and dragging. You're just waiting for a time to go up to your room. You're just waiting, waiting, waiting."

"Whoever's out there, we're just begging you to bring our girls back home," she said.

A $50,000 reward had been offered for information that led to the arrest and conviction of the person responsible for the girls' disappearance.

Australian economy grows 0.5% in Sep quarter

SYDNEY: Australia's economy grew 0.5 per cent in the three months to September and 3.1 per cent from a year earlier, data showed Wednesday, with China's slowdown dampening growth.

The Australian Bureau of Statistics said gross domestic product (GDP) grew a seasonally adjusted 0.5 per cent in the quarter, in line with expectations, driven by the mining and manufacturing sectors.

It compares with growth of 0.6 per cent in the three months to June and year-on-year growth of 3.7 per cent last quarter, lending weight to the central bank's decision to lower interest rates on Tuesday to stimulate the economy.

Mining contributed 0.4 per cent to quarterly GDP growth, despite a plunge in commodity prices due to a cooling in China's economy that saw a 4.0 per cent drop in Australia's terms of trade -- the value of its exports against its imports.

Private business investment accounted for 0.5 per cent of GDP growth and consumer spending added 0.2 per cent. Falling government spending detracted 0.5 per cent.

The Reserve Bank of Australia slashed the official interest rate by 25 basis points to 3.0 per cent this week -- their equal lowest since RBA independence in the early 1990s.

FDI in retail will not help farmers: V K Singh

NEW DELHI: Former Army chief Gen V K Singh slammed the government's decision to bring in FDI in multi-brand retail saying the move would not benefit farmers as procurement would be outsourced from other countries at cheaper prices.

Joining in a Parliament gherao by farmers under the banner of the Rashtriya Kisan Mazdoor Sangathan (RKMS) on Tuesday, Singh demanded that the Rangarajan committee report on freeing the sugar sector be junked.

On FDI, he said even when Pepsico came to India, it was said that it would help farmers but that was never the case. "In India, we have an excellent model in terms of Amul to empower farmers. We can bring about the same change what people are trying to bring through FDI by making suitable modifications to the Amul model," he said.

Singh said farmers would not be benefited because the multi-brand retailers would import cheap items from other countries and not procure them from within India.

On the Rangarajan committee report, Singh said, "No politician has worked for farmers. They get votes from you people by promising many things, but they forget that there is a community called farmers after the elections. Next time, when you go to the polling booth, think who will fight for you and then vote only for that person.''

However, the former Army chief said he was not supporting any particular party but was only asking farmers to keep their "betterment in mind" before pressing the EVM button.

The protesters gathered near Parliament Street police station, less than a kilometre from Parliament House, and raised slogans demanding that the report be rejected.

RKMS's V M Singh said there was a need to raise a 'Kisan Sena' in the country that would fight for farmers' rights. He added that if the government did not pay heed to the farmers' demands, they would go on indefinite dharna at Boat Club.

Dubbing as "anti-farmer" the Rangarajan committee report which has recommended phased decontrol of the highly regulated Rs 80,000-crore sugar industry, he said the prime minister and Parliament should not accept the report.

North Star Closer to Earth Than Thought

The North Star has been a guiding light for countless generations of navigators. But a new study reveals that its distance to Earth may have been grossly overestimated.

In fact, the North Star—also called Polaris—is 30 percent closer to our solar system than previously thought, at about 323 light-years away, according to an international team who studied the star's light output.

Using Russia's 6-Meter Telescope, the researchers were able to calculate the North Star's distance from our solar system by analyzing its spectrum of light and obtaining data on its temperature and changes in intrinsic brightness over time.

That significantly revises the previously accepted value of 434 light-years, which was obtained by the European star-mapping satellite Hipparcos in the 1990s. (Take a solar system quiz.)

The new discovery of a closer North Star is "most unexpected for what is considered to be one of the Hipparcos satellite's most solid results," said study leader David Turner, an astronomer at Saint Mary's University in Halifax, Nova Scotia.

North Star a Celestial Beacon

The North Star's claim to fame is due to its fixed position in the sky for Northern Hemisphere observers—aligned with Earth's northern axis—while other stars appear to wheel around it.

Known to fade and brighten over a four-day period, this celestial beacon of true north is considered the closest and brightest member of a class of stars called Cepheids that change in brightness over time. (See star pictures.)

The star is also a type of cosmological yardstick used by researchers to measure great cosmic distances out to billions of light-years.

For this reason, it's vital for our understanding of the cosmos that scientists get a reliable grip on the North Star's true distance, emphasized Turner, whose study will appear in Astrophysical Journal Letters.

For instance, research on dark energy—the mysterious force thought to be causing the universe to fly apart faster over time—is dependent on stars such as the North Star.

(See "New Galaxy Maps to Help Find Dark Energy Proof?")

Unseen Object Orbiting North Star?

The new results also located nearly a half dozen stars that appear to be surrounding the North Star and show signs that they have all once belonged to the same star cluster, which has now dispersed.

"This system is known to contain two other stars in addition to the Cepheid stars, but there may be yet another unseen object orbiting Polaris ... a massive orbiting planet for example," he added.

"There definitely remain a few oddities to keep Polaris an object of study for many years to come."

Tasting DNA-Altered Salmon That May Hit US Plates

Deep in the rain forests of Panama, in a secret location behind padlocked gates, barbed-wire fences and over a rickety wooden bridge, grows what could be the most debated food product of our time.

It may look like the 1993 hit movie "Jurassic Park," but at this real-life freshwater farm scientists are altering the genes not of dinosaurs -- but of fish.

They are growing a new DNA-altered saltwater fish in the mountains, far from the sea -- a salmon that could be the first genetically altered animal protein approved for the world to eat. If it is approved, this would be a landmark change for human food.

But it is one critics call "Frankenfish."

"The idea of changing an animal form, I think, is really creepy," said Gary Hirshberg, founder of Stonyfield Farm, an organic dairy farm. "When you move the DNA from a species into another species ... you create a new life form that's so new and so unique that you can get a patent for it."

And until now, AquaBounty, the multinational biotech company that for 20 years has been developing this giant fish, has kept it under close wraps.

The press has never been invited to its Prince Edward Island laboratory on the Canadian maritime coast, and its fish farm location in Panama has been kept secret out of fear of sabotage.

The Food and Drug Administration has seen it, but few from the outside. In fact, the last public tour of any kind was four years ago.

AquaBounty Creates 'Fort Knox for Fish'

ABC News was given exclusive access to see the facilities up close and an opportunity to taste this mysterious fish that FDA scientists say "is as safe as food from conventional Atlantic salmon," although have yet to officially approve it for public sale.

Ron Stotish, the president and CEO of AquaBounty Technologies, the company that created and hopes to market the eggs of this salmon to independent fish farms around the world, told ABC News it has employed bio-security measures, creating a "Fort Knox for fish," to ensure safety for the fish and prevent cross-contamination with the wild.

Entry to both facilities begins with body suits and iodine baths for shoes, which serves to keep the fish safe from germs.

Inside these protected tanks, America gets the first up-close look at the final product, the fish that has the food police up in arms.

"These are very healthy, beautiful Atlantic salmon," Stotish said.

With one big difference -- the growth rate of a regular salmon compared to that of an AquaBounty genetically modified fish.

While the AquaBounty fish do not grow to a size larger than normal salmon, they get to full size much faster, cutting costs for producers.

A normal-size 1-year-old Atlantic salmon averages 10 inches long, while the genetically modified fish at the same age is more than two times larger, coming in at 24 inches.

Salmon is the second most popular seafood in America. According to the National Oceanic and Atmospheric Administration, the average size of an Atlantic salmon is 28 inches to 30 inches and 8 pounds to 12 pounds after two years at sea.

How do they accomplish the accelerated growth?

"They differ by a single gene," Stotish said.

But, it's that single gene change that makes the DNA-altered salmon grow much faster than a normal Atlantic salmon, because it's really three fish in one.

AquaBounty scientists have taken a growth gene from the Chinook salmon and inserted it into the DNA of the Atlantic salmon because Chinooks grow fast from birth, while Atlantics do not.

"Salmon in their first two years of life grow very slowly," Stotish said.

Boehner, House GOP leaders offer ‘fiscal cliff’ counterproposal

House GOP leaders endorsed a debt-reduction plan Monday that would raise tax collections by $800 billion over the next decade, but they refused to budge on higher tax rates for the wealthy, the central issue dividing Republicans and Democrats.

In making a counteroffer to President Obama, House Speaker John A. Boehner (R-Ohio) and other senior Republicans suggested that a framework laid out by Democrat Erskine Bowles last year could serve as a starting point for talks aimed at averting the year-end “fiscal cliff.”

Police raid highway operator over Japan tunnel collapse

TOKYO: Japanese police on Tuesday raided offices belonging to a highway operator over a weekend tunnel collapse that killed nine people.

More than eight officers from the Yamanashi Police Department entered the office of NEXCO in Hachioji, western Tokyo, a spokesman for the highway operator said.

"We are fully cooperating with the authorities over the accident," the spokesman told AFP.

Police also plan to raid more of the company's offices in connection with the tragedy at the Sasago tunnel, which passes through hills near Mount Fuji, Japanese broadcaster NHK said.

On Monday, the Japanese government ordered inspections of ageing highway tunnels following the accident as suspicion over the cause of the accident centred on decaying ceiling supports.

Patels clearly hold the key

AHMEDABAD: Ever since former Congress chief minister Madhavsinh Solanki formulated KHAM - a political axis comprising kshatriyas, harijans, adivasis and Muslims - that helped Congress a record 149 seats in 1985 - Patels have steadily gravitated towards the BJP. The Congress has not tasted power in Gujarat after 1990 thanks to rising Patel power.

In all, there are 148 Patel candidates in fray representing the three main players - BJP, Congress and GPP. Leuvas, a Patel sub-caste which Keshubhai Patel represents, dominate at least 40 out of the total 182 seats in Gujarat, mostly in Saurashtra, south and central Gujarat. Leuva Patels constitute anything between 20% to 50% votes in these 40 seats. Kadva Patels are in large numbers in north Gujarat. With Keshubhai threatening to make a dent into BJP's vote share, mainly due to the clout he enjoys in his community, BJP has also fielded a large number of Patels. But BJP's Patel leaders like Purshottam Rupala, Anandiben Patel and RC Faldu are no match to Keshubhai.

Modi tried his best to rope in Naresh Patel, a community leader who has become a rallying point for the economically powerful community, which now wants to re-gain its lost political glory by helping both the GPP and Congress.

Besides, the Bharatiya Kisan Sangh, which has a large following among Patel farmers, is aggressively campaigning against Modi. VHP leader Pravin Togadia, himself a Leuva Patel, is likely to make matters worse for the Gujarat CM.
