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.

(Explore an interactive time line of Mars exploration in National Geographic magazine.)

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."

(See "Curiosity Landing on Mars Greeted With Whoops and Tears of Jubilation.")

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."

McAfee Arrested for Entering Guatemala Illegally













Eccentric software tycoon John McAfee, wanted in Belize for questioning in the shooting death of his neighbor, has been arrested in Guatemala for entering the country illegally, his Guatemala attorney told ABC News.


Before McAfee's arrest, he told ABC News in an exclusive interview he would be seeking asylum in Guetemala. McAfee was arrested by the Central American country's immigration police and not the national police, said his attorney, who was confident his client would be released within hours.


"Thank God I am in a place where there is some sanity," said McAfee, 67, before his arrest. "I chose Guatemala carefully."


McAfee said that in Guatemala, the locals aren't surprised when he says the Belizean government is out to kill him.


"Instead of going, 'You're crazy,' they go, 'Yeah, of course they are,'" he said. "It's like, finally, I understand people who understand the system here."


But McAfee added he has not ruled out moving back to the United States, where he made his fortune as the inventor of anti-virus software, and that despite losing much of his fortune he still has more money than he could ever spend.


In his interview with ABC News, a jittery, animated but candid McAfee called the media's representation of him a "nightmare that is about to explode," and said he's prepared to prove his sanity.


McAfee has been on the run from police in Belize since the Nov. 10 murder of his neighbor, fellow American expatriate Greg Faull.


During his three-week journey, said McAfee, he disguised himself as handicapped, dyed his hair seven times and hid in many different places during his three-week journey.


He dismissed accounts of erratic behavior and reports that he had been using the synthetic drug bath salts. He said he had never used the drug, and said statements that he had were part of an elaborate prank.

Anti-Virus Pioneer John McAfee Hiding in Belize: Police Watch Video





Investigators said that McAfee was not a suspect in the death of the former developer, who was found shot in the head in his house on the resort island of San Pedro, but that they wanted to question him.


McAfee told ABC News that the poisoning death of his dogs and the murder just hours later of Faull, who had complained about his dogs, was a coincidence.


McAfee has been hiding from police ever since Faull's death -- but Telesforo Guerra, McAfee's lawyer in Guatemala, said the tactic was born out of necessity, not guilt.


"You don't have to believe what the police say," Guerra told ABC News. "Even though they say he is not a suspect they were trying to capture him."


Guerra, who is a former attorney general of Guatemala, said it would take two to three weeks to secure asylum for his client.


According to McAfee, Guerra is also the uncle of McAfee's 20-year-old girlfriend, Samantha. McAfee said the government raided his beachfront home and threatened Samantha's family.


"Fifteen armed soldiers come in and personally kidnap my housekeeper, threaten Sam's father with torture and haul away half a million dollars of my s***," claimed McAfee. "If they're not after me, then why all these raids? There've been eight raids!"


Before his arrest, McAfee said he would hold a press conference on Thursday in Guatemala City to announce his asylum bid. He has offered to answer questions from Belizean law enforcement over the phone, and denied any involvement in Faull's death.


False Report of McAfee Arrest on Mexico Border


Over the weekend, a post on McAfee's blog claimed that he had been detained on the Belizean/Mexico border.


On Monday, a follow-up post said that the "John McAfee" taken into custody was actually a "double" who was carrying a North Korean passport with McAfee's name.


That post claimed that McAfee had already escaped Belize and was on the run with Samantha and two reporters from Vice Magazine.


McAfee did not reveal his location in that post, and a spokesman for Belize's National Security Ministry, Raphael Martinez, told ABC News on Monday that no one by McAfee's name was ever detained at the border and that Belizean security officials believed McAfee was still in their country.


However, a photo posted by Vice magazine on Monday with their article, "We Are With John McAfee Right Now, Suckers," apparently had been taken on an iPhone 4S and had location information embedded in it that revealed the exact coordinates where the photo was taken -- in the Rio Dulce National Park in Guatemala -- as reported by Wired.com.

N. Korea completes installing rocket






SEOUL: North Korea has completed installing a long-range rocket on its launch pad, ahead of its planned launch this month in defiance of widespread international condemnation, a report said Wednesday.

All three stages of the Unha-3 rocket have been placed on the pad at the North's Sohae satellite launch station, a South Korean government source told Yonhap news agency.

"Some workers are pulling out of the site," the source said.

Pyongyang announced on Saturday that it intends to launch the rocket between December 10 and 22.

The United States and its key Asian allies South Korea and Japan have condemned the move as a disguised ballistic missile test that violates UN resolutions triggered by Pyongyang's two nuclear tests in 2006 and 2009.

North Korea is now expected to install support equipment, such as radar and cameras, before fueling the carrier, Yonhap said.

US Secretary of State Hillary Clinton on Tuesday urged her NATO allies and Russia to press North Korea to call off the mission.

"The United States is deeply concerned about North Korea's recent announcement that it plans to carry out another rocket launch," Clinton told a meeting of the NATO-Russia council.

"We urge everyone here to publicly call upon North Korea to comply fully with its UN Security Council obligations."

Pyongyang insists the launch is a "peaceful" and purely scientific mission aimed at placing a satellite in orbit.

A previous attempt in April failed when the carrier exploded shortly after take-off.

China has expressed "concern" at the launch plan, with the foreign ministry urging "relevant parties (to) act in a way that is more conducive to the stability of the Korean peninsula".

Russia added its "regret" and noted that North Korea was obliged to abide by UN resolutions.

But analysts say the international community is running out of options for pressuring the impoverished but nuclear-armed North, which is already under layers of sanctions.

The six-party, aid-for-denuclearisation talks have been at a standstill since Pyongyang walked of the forum in April 2009. It staged its second nuclear test a month later.

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.

Subway Push Murder Suspect Implicated Self: Police













A suspect believed to be responsible for throwing a man into the path of an oncoming New York City subway train who was taken into custody today has made statements implicating himself, police said.


According to Deputy Commissioner for Public Information Paul Browne, the suspect has been questioned by police since at least early afternoon and while the suspect is in police custody, he has not been officially charged.


Police are continuing to question the suspect and more lineups have been scheduled for tomorrow, Browne said.


Police have not released the suspect's name but began questioning him Tuesday afternoon about the death of Ki-Suck Han, 58, of Queens, N.Y.


Han was tossed onto the subway track at 49th Street and Seventh Avenue around 12:30 p.m. Monday after Han confronted a mumbling man who was alarming other passengers on the train platform. Han tried to scramble back onto the platform, but was crushed by an oncoming train.


The suspect fled the station, prompting a police dragnet for a man described by witnesses and see on surveillance video as a 6-foot-tall, 200-pound black man wearing dreadlocks in his hair.


Witnesses tried to revive the victim after he was hit and provided descriptions of the suspect to police.


Dr. Laura Kaplan, medical resident at Beth Israel Medical Center who was standing on the platform during the incident rushed to give Han aid after he was hit, she said in a statement released by her medical practice today.

"A security guard and I performed 3-4 minutes of chest compressions. I hope the family may find some comfort in knowing about the kindness of these good Samaritans, as they endure this terrible loss," Kaplan said.


"I would like the family to know that many people in the station tried to help Mr. Han by alerting the subway personnel," she said.


Kaplan said she wanted to console the family of Han, who she called "a brave man trying to protect other passengers that he did not know."


The suspect had reportedly been mumbling to himself and disturbing other passengers, according to ABC News affiliate WABC. Police told WABC that the suspect could be mentally disturbed.


The suspect could be heard arguing with Han just moments before he hurled Han onto the track bed, according to surveillance video released by the police. The suspect is heard telling the victim to stand in line and "wait for the R train."


A freelance photographer for the New York Post was on the platform and said he ran towards the train flashing his camera hoping to alert the train to stop in time, but the train caught Han against the shoulder deep platform wall.


The photographer, R. Umar Abbasi, caught an eerie photo of Han with his head and arms above the platform and staring at the oncoming train.


Han was treated by EMS workers on the platform for traumatic arrest and rushed to Roosevelt Hospital, where he was pronounced dead, according to the Fire Department of New York.


"I just heard people yelling. The train came to an abrupt stop about three-quarters into the station and that's when I heard a man was hit by a train," Patrick Gomez told ABC News affiliate WABC.


Police set up a command post outside the train station Monday night searching nearby surveillance cameras to try and get a clear image of the suspect, reports WABC. They said Tuesday that the investigation is ongoing.


Anyone with information is asked to call Crime Stoppers at 1-800-577-TIPS (8477). The public can also submit tips by logging onto the Crime Stoppers website at www.nypdcrimestoppers.com or by texting their tips to 274637 (CRIMES) then enter TIP577. All calls are strictly confidential.

Tough new anti-dumping measures in Australia






SYDNEY: Australia Tuesday announced tough new anti-dumping measures to counter an influx of cheap products that are hurting its struggling manufacturing industry and costing jobs.

Prime Minister Julia Gillard said the moves would "deliver stronger protection for Australian industry against unfair competition from overseas".

"It is not acceptable for Australian jobs to be put at risk by products being dumped into this country," she said, while refusing to single out any specific nations or put a value on dumped goods.

Dumping refers to the unfair trade practice where imported goods are sold at prices below their normal value, hurting local businesses and their workers.

"The government will support manufacturing by strengthening the system for investigating dumping and applying remedies where dumping is injuring local producers," Gillard said.

The measures include establishing a new Anti-Dumping Commission to probe complaints while boosting funding to Customs by nearly A$25 million (US$26 million) so it can double the number of investigators.

New laws will also be introduced to deal with overseas producers who deliberately circumvent Australia's anti-dumping rules.

Australia's manufacturing industry employs a million people with products affected by dumping in recent years including steel, chemicals, aluminium goods and paper products.

While Australia's mining-driven economy dodged recession during the global financial crisis, its manufacturers have been hit not only by cheap dumped products, but a high Australian dollar and intense global competition.

The Construction, Forestry, Mining and Energy Union, which has long campaigned with other unions for a dedicated anti-dumping commission, welcomed the announcement.

"Australian industry and jobs have been suffering from the impact of dumped goods for too long," said CFMEU national secretary Michael O'Connor.

"This new agency should help level the playing field for locally produced goods through investigating and penalising dumpers."

Burney writes to Pak PM, president condemning temple demolition

AMRITSAR: Pakistan's former federal minister for human rights Ansar Burney has shot off letters to Pakistan's prime minister and president seeking immediate action against the real estate builder on whose behest the century-old Sri Rama Pir temple in Karachi was demolished on Saturday.

Talking to TOI over phone from Karachi, Burney said that it was a case of blasphemy and government of Pakistan should deal with iron hand against the persons responsible for demolition of the temple.

Karachi based President of Pak Hindu Seva Trust, Sanjesh S Dhanja said that there was great disappointment among Hindus of Pakistan following demolition of temple. "I wonder that despite stay orders, how could anyone demolish the temple?," he questioned, adding that Hindus of Pakistan believed in police and judiciary of the country.

Delhi Minorities Commission has also condemned demolition of the temple and has demanded from Pakistan government to reconstruct the temple to restore confidence among the minority Hindu community in Pakistan. Chairman, Delhi Minorities Commission, Safdar H Khan said that razing of a religious place of any community was the most deplorable act. Khan, who is also vice-president of India Islamic Cultural Center said that he would write to Pakistan high commission to express his resentment and would also demand reconstruction of the temple by Pakistan government.

Mars Rover Detects Simple Organic Compounds


NASA's Mars rover Curiosity has detected several simple carbon-based organic compounds on Mars, but it remains unclear whether they were formed via Earthly contamination or whether they contain only elements indigenous to the planet.

Speaking at the American Geophysical Union annual meeting in San Francisco, Curiosity mission leaders also said that the compound perchlorate—identified previously in polar Mars—appeared to also be present in Gale Crater, the site of Curiosity's exploration.

The possible discovery of organics—or carbon-based compounds bonded to hydrogen, also called hydrocarbons—could have major implications for the mission's search for more complex organic material.

It would not necessarily mean that life exists now or ever existed on Mars, but it makes the possibility of Martian life—especially long ago when the planet was wetter and warmer—somewhat greater, since available carbon is considered to be so important to all known biology.

(See "Mars Curiosity Rover Finds Proof of Flowing Water—A First.")

The announcements came after several weeks of frenzied speculation about a "major discovery" by Curiosity on Mars. But project scientist John Grotzinger said that it remains too early to know whether Martian organics have been definitely discovered or if they're byproducts of contamination brought from Earth.

"When this data first came in, and then was confirmed in a second sample, we did have a hooting and hollering moment," he said.

"The enthusiasm we had was perhaps misunderstood. We're doing science at the pace of science, but news travels at a different speed."

Organics Detected Before on Mars

The organic compounds discovered—different combinations of carbon, hydrogen, and chlorine—are the same or similar to chlorinated organics detected in the mid-1970s by the Viking landers.

(Related: "Life on Mars Found by NASA's Viking Mission?")

At the time, the substances were written off as contamination brought from Earth, but now scientists know more about how the compounds could be formed on Mars. The big question remains whether the carbon found in the compounds is of Martian or Earthly origin.

Paul Mahaffy, the principal investigator of the instrument that may have found the simple organics—the Sample Analysis at Mars (SAM)—said that while the findings were not "definitive," they were significant and would require a great deal of further study.

Mahaffy also said the discovery came as a surprise, since the soil sample involved was hardly a prime target in the organics search. In fact, the soil was scooped primarily to clean out the rover's mobile laboratory and soil-delivery systems.

Called Rocknest, the site is a collection of rocks with rippled sand around them—an environment not considered particularly promising for discovery. The Curiosity team has always thought it had a much better chance of finding the organics in clays and sulfate minerals known to be present at the base of Mount Sharp, located in the Gale Crater, where the rover will head early next year.

(See the Mars rover Curiosity's first color pictures.)

The rover has been at Rocknest for a month and has scooped sand and soil five times. It was the first site where virtually all the instruments on Curiosity were used, Grotzinger said, and all of them proved to be working well.

They also worked well in unison—with one instrument giving the surprising signal that the minerals in the soil were not all crystalline, which led to the intensive examination of the non-crystalline portion to see if it contained any organics.

Rover Team "Very Confident"

The simple organics detected by SAM were in the chloromethane family, which contains compounds that are sometimes used to clean electronic equipment. Because it was plausible that Viking could have brought the compounds to Mars as contamination, that conclusion was broadly accepted.

But in 2010, Chris McKay of NASA's Ames Research Center and Rafael Navarro-Gonzalez of the National Autonomous University of Mexico published an influential paper describing how dichloromethane can be a byproduct of the heating of other organic material in the presence of the compound perchlorate.

They conducted the experiment because NASA's Phoenix mission had discovered large amounts of perchlorate in the northern polar soil of Mars, and it seems plausible that it would exist elsewhere on the planet.

"In terms of the SAM results, there are two important conclusions," said McKay, a scientist on the SAM team.

"The first is confirming the perchlorate story—that it's most likely there and seems to react at high temperatures with organic material to form the dichloromethane and other simple organics."

"The second is that we'll have to either find organics without perchlorates nearby, or find a way to get around that perchlorate wall that keeps us from identifying organics," he said.

Another SAM researcher, Danny Glavin of Goddard, said his team is "very confident" about the reported detection of the hydrocarbons, and that they were produced in the rover's ovens. He said it is clear that the chlorine in the compounds is from Mars, but less clear about the carbon.

"We will figure out what's going on here," he said. "We have the instruments and we have the people. And whatever the final conclusions, we will have learned important things about Mars that we can use in the months ahead."

Author of the National Geographic e-book Mars Landing 2012, Marc Kaufman has been a journalist for more than 35 years, including the past 12 as a science and space writer, foreign correspondent, and editor for the Washington Post. He is also author of First Contact: Scientific Breakthroughs in the Hunt for Life Beyond Earth, published in 2011, and has spoken extensively to crowds across the United States and abroad about astrobiology.
