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.

Missing Iowa Girls: One Mother Takes 2nd Polygraph Watch Video

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.

Kerry balances refocused devotion to Senate, talk of Cabinet nomination

An international treaty promoting the rights of the disabled across the globe failed in the Senate Tuesday, but it gave Sen. John F. Kerry , chairman of the Foreign Relations Committee, a chance to lay out a diplomatic vision that could serve as blueprint if he becomes President Obama’s next secretary of state.

The point of the treaty, Kerry said, was to urge the world to be more the United States.

Britain braces for key budget update

LONDON: British finance minister George Osborne unveils his budget update on Wednesday, and will likely admit it could take longer than expected to slash the deficit as a result of the weaker-than-expected economy.

Chancellor of the Exchequer Osborne was to deliver his Autumn Statement before parliament at 1230 GMT, when the Office for Budget Responsibility (OBR) fiscal watchdog will also publish its latest growth and borrowing forecasts.

Osborne has already warned that economic recovery will take longer than hoped but insisted that abandoning the government's tough deficit-slashing austerity measures would be catastrophic amid the ongoing eurozone debt crisis.

"We had two targets, one was to get debt share falling as a share of national income by 2015/16 and also to balance the current budget," the chancellor told BBC television over the weekend.

"It's clearly taking longer to deal with Britain's debts; it's clearly taking longer to recover from the financial crisis than anyone would have hoped but we have made real progress."

Ahead of the budget update, Osborne pledged Tuesday to invest £5.0 billion in schools, transport and science over the next two fiscal years, with the cash sourced from a new raft of spending cuts across most civil service departments.

And on Monday, Osborne launched a campaign against "tax dodgers" and "cowboy advisers" to claw back £2.0 billion a year, as lawmakers alleged that multinationals such as Starbucks and Google are avoiding huge tax bills.

The OBR was meanwhile expected to lower its gross domestic product (GDP) forecasts as the economy faces major headwinds from state austerity, inflationary pressures and the eurozone's ongoing crisis.

Osborne had in March forecast that the British economy would grow by 0.8 per cent this year, followed by 2.0 per cent in 2013 and 2.7 per cent in 2014.

Weaker economic growth would slash taxation receipts and spark upward revisions to its official borrowing targets, according to analysts.

Alongside Osborne's budget in March, the OBR predicted that public sector net borrowing (PSNB) as a proportion of economic output would begin to fall in 2015/2016, after peaking at 76.3 per cent of GDP in 2014/15.

And it forecast state borrowing would reach £120 billion ($192 billion, 148 billion euros) in the 2012/2013 financial year ending in March, compared with £121.4 billion in 2011/2012.

But with PSNB already standing at £73.3 billion and four months of the financial year to go, Osborne could breach the target.

Recent official data showed Britain had escaped from recession in the third quarter of this year, with its economy growing 1.0 per cent.

However, experts argue this was due to one-off factors like the London Olympics and rebounding activity after public holidays in the second quarter.

The Conservative-Liberal Democrat coalition government imposed austerity measures to slash a record deficit inherited from the previous Labour administration. Opposition Labour politicians maintain that the cuts pushed the economy into a painful double-dip recession.

The Organisation for Economic Co-operation and Development urged Osborne last week to push back his debt reduction targets rather than drive through more growth-damaging austerity.

Meanwhile, the country's official statistics watchdog on Tuesday warned the government to stop claiming that real-terms National Health Service spending had increased after calculating funds had actually fallen slightly.

The UK Statistics Authority said Health Secretary Jeremy Hunt should "clarify" claims on the Conservative party website that "we have increased the NHS budget in real terms in each of the last two years".

India urges Israel to speed up defence projects

NEW DELHI: India has asked Israel to speed up crucial bilateral defence projects, including the around Rs 13,000 crore development of two advanced surface-to-air missile (SAM) systems to arm Indian armed forces against hostile aircraft, drones and helicopters.

This came at the 10th joint working group on defence cooperation here, co-chaired by defence secretary Shashikant Sharma and Israeli defence ministry director-general Major-General Ehud Shani.

While the regional and global security situation, including the recent Israel-Hamas ceasefire, figured in the talks, the focus was on bilateral defence training programmes, exchanges, R&D projects and armament deals.

Israel is India's second largest defence supplier, second only to Russia, but the expansive ties are largely kept under wraps due to political sensitivities. Tel Aviv records military sales worth around $1 billion to New Delhi every year, ranging from Heron and Searcher UAVs, Harpy and Harop 'killer' drones to Barak anti-missile defence systems and Green Pine radars, Python and Derby air-to-air missiles.

Sources said India expressed "concern'' at the "two-year delay'' in completion of the long-range SAM (LR-SAM) project, sanctioned in December 2005 at a cost of Rs 2,606 crore to arm Indian warships.

There are "minor hitches'' even in the bigger Rs 10,076 crore medium-range SAM (MR-SAM) project, sanctioned in February 2009 for air defence squadrons of IAF.

Both the SAM systems, being developed by Israeli Aerospace Industries (IAI) in collaboration with DRDO, have the same missile with an interception range of 70-km. They are to be produced in bulk by defence PSU Bharat Dynamics (BDL) to plug the existing holes in India's air defence cover.

"While the multi-function surveillance and threat radars, weapon control systems with data links and the like of the LR-SAM have all been tested, there has been delay in the missiles being developed by IAI,'' said a source.

"But the Israelis said everything was sorted out now and they will try to make up for the delay. DRDO has already finished its work on the propulsion and other systems,'' he added. Incidentally, the LR-SAM project was to be completed by May this year.

Another major missile project, worth around $1 billion, that Israel could bag is the one to supply third-generation anti-tank guided missiles (ATGMs) to the 1.13-million strong Indian Army. The Army has already trial-evaluated the Israeli 'Spike' ATGM after the US offer of its 'Javelin' missiles was shelved due to Washington's reluctance to undertake "transfer of technology'' to ensure BDL can make them in large numbers, as reported by TOI earlier.

India is also in commercial negotiations for another two advanced Israeli Phalcon AWACS (airborne warning and control systems), capable of detecting hostile aircraft, cruise missiles and other incoming aerial threats far before ground-based radars, at a cost of over $800 million. The first three Phalcon AWACS were inducted by IAF in 2009-2010 under the $1.1 billion tripartite agreement between India, Israel and Russia.

Scientific Results From Challenger Deep

Jane J. Lee

The spotlight is shining once again on the deepest ecosystems in the ocean—Challenger Deep in the Mariana Trench (map) and the New Britain Trench near Papua New Guinea. At a presentation today at the American Geophysical Union's conference in San Francisco, attendees got a glimpse into these mysterious ecosystems nearly 7 miles (11 kilometers) down, the former visited by filmmaker James Cameron during a historic dive earlier this year.

Microbiologist Douglas Bartlett with the University of California, San Diego described crustaceans called amphipods—oceanic cousins to pill bugs—that were collected from the New Britain Trench and grow to enormous sizes five miles (eight kilometers) down. Normally less than an inch (one to two centimeters) long in other deep-sea areas, the amphipods collected on the expedition measured 7 inches (17 centimeters). (Related: "Deep-Sea, Shrimp-like Creatures Survive by Eating Wood.")

Bartlett also noted that sea cucumbers, some of which may be new species, dominated many of the areas the team sampled in the New Britain Trench. The expedition visited this area before the dive to Challenger Deep.

Marine geologist Patricia Fryer with the University of Hawaii described some of the deepest seeps yet discovered. These seeps, where water heated by chemical reactions in the rocks percolates up through the seafloor and into the ocean, could offer hints of how life originated on Earth.

And astrobiologist Kevin Hand with the Jet Propulsion Laboratory in Pasadena, California, spoke about how life in these stygian ecosystems, powered by chemical reactions, could parallel the evolution of life on other planets.

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.

Shimla takes first step towards modern transportation

SHIMLA: Shimla residents can now hope to get a new transportation system in the near future with Global Energy Basil (GBL) of Germany, a partner of European Union, showing keen interest in Rs 3,000cr comprehensive mobility plan prepared by Shimla municipal corporation. Having shortlisted Shimla for funding purpose, GBL has invited Shimla municipal corporation for presentation in January.

Shimla town faces a serious problem of traffic congestion due to peculiar geography and age-old construction. The road infrastructure was created during the British rule to cater to the needs of the then population, and little progress has been made till now. With the passage of time, increase in population and inflow of tourists further increased the problems.

To decongest Shimla, Himachal Pradesh government has decided to form satellite towns on the outskirts to save original character of the city which otherwise is bursting at seams with over-population and over-construction. Three satellite towns have been proposed at Vaknaghat on Shimla-Chandigarh highway, Fagu on Shimla-Rampur highway and Ghandal in-between Ghanahatti and Shalaghat on Shimla-Bilaspur highway.

If GBL agrees to fund the comprehensive mobility plan of Shimla, the city would get relief from traffic congestion and pollution. Sources said that GBL has already funded around 40 such projects in other parts of the world, including Beijing, Kampala and Islamabad.

Comprehensive mobility plan submitted to Global Energy Basil has provision of regulating 48,000 vehicles in the city in a planned manner. Submitted plan has the provision for ropeways at the cost of $623 million and tunnels estimated at $63 million, sources said.

Confirming the development, municipal commissioner Dr M P Sood said that acceptance of proposal by GBL is a big success. "For the first time, a mega project has been planned for Shimla and in January, a presentation would be made to GBL during its annual convention," he said.

Sood said that after Kochin, Shimla is second city in India where GBL has shown interest to fund the project. "The project envisages cable ropeways, mono rail, widening of existing corridors and construction of escalators," he said.
