NASA Scientists Build Harpoon to Shoot Comets (SPACE.com)

Captain Ahab may have wanted to harpoon a giant white whale, but NASA has a whole other target in mind.

Scientists at NASA?s Goddard Space Flight Center are designing a small harpoon that would fire into and collect samples from nearby comets. Because comets are frozen chunks of ice and dust dating back to the formation of our solar system, they may hold clues to the origin of the planets and life as we know it.

"One of the most inspiring reasons to go through the trouble and expense of collecting a comet sample is to get a look at the 'primordial ooze' ? biomolecules in comets that may have assisted the origin of life," Donald Wegel, lead engineer for the project, said in a statement.

Previous NASA missions have already found amino acids ? molecules that are important for life and serve as the building blocks of proteins ? in comets and meteorites. The new project could discover other ingredients necessary for life, supporting the theory that comet and meteorite impacts may have given a boost to the development of life on Earth by delivering vital biomolecules.

Another goal of collecting comet samples is to figure out how comets are formed. This information would provide scientists with important details on how best to deflect any dangerous space rocks hurling toward Earth.

The NASA team is currently trying to figure out the best tip design, explosive powder charge, mass and cross-section for the harpoon. To do this, they are using a six-foot tall crossbow with a half-inch thick steel cable bow string to fire harpoon tips at various speeds into different materials, such as sand, ice and rock salt. They are also developing a sample collection chamber to nestle into the hollow tip. ?"[The chamber] has to remain reliably open as the tip penetrates the comet's surface, but then it has to close tightly and detach from the tip so the sample can be pulled back into the spacecraft," explained Wegel. [How NASA Could Get Its Groove Back]

NASA envisions that a single spacecraft would carry multiple harpoons with a variety of powder charges to handle different areas on a comet. The spacecraft would rendezvous with a comet, choose a target and fire the appropriate harpoon based on the presumed material composition of the area. The open collection chamber will gather samples as the harpoon tip dives deeper into the surface of the comet. Once the harpoon reaches its maximum depth, the collection chamber will snap shut and the spacecraft will reel it in, leaving the harpoon tip in the comet. This design will allow scientists to collect comet samples without the difficulty of actually having land on the comet.

The NASA team is still in the proof-of-concept stage for the project. Once they prove that the harpoon will work, they will have to apply for funding to build the instrument.

Oil prices up on economic news, Mideast tension (AP)

NEW YORK ? Oil prices jumped about 2 percent Tuesday as tensions rose in Iran and strong retail sales put a rosier glow on the U.S. economy.

Benchmark crude rose $2.37, or 2.4 percent, to end the day at $100.14 per barrel in New York. Brent crude, which is used to price foreign oil imported by some U.S. refineries, rose $2 to finish at $109.08 a barrel in London.

Analysts said traders reacted to more saber-rattling by Iran, as the country continues to deny accusations that it is developing nuclear weapons. Iran's navy now plans to run drills, practicing a closing of the narrow Strait of Hormuz at the mouth of the Persian Gulf.

About a third of the world's oil tanker traffic passes through that strategic waterway, and even a brief closure could crimp oil supplies around the world. Longer, more expensive routes would have to be used to transport crude from the region.

"There's just a lot of chatter out there," said Addison Armstrong, director of market research at Tradition Energy. "There are a lot of possibilities of what might happen," but traders are choosing to err on the side of buying rather than selling.

Rumors swirled during the day about what the Federal Reserve might do to further stimulate the economy. The Fed, which met Tuesday, left open the possibility for new steps to stimulate the economy next year if needed, but said the nation's economy appeared to be slowly recovering..

The Organization of Petroleum Exporting Countries will meet Wednesday in Europe to decide how much oil to bring to the market. OPEC trimmed its forecast for global oil demand in 2012. But at 88.9 million barrels per day, OPEC's outlook still puts world demand at a record high next year.

On Tuesday the government said that U.S. consumers' retail spending rose in November for the sixth straight month. The U.S. economy is driven by consumer spending, and more spending points to stronger demand for oil. A separate government report said that U.S. businesses built up their stockpiles in October. That's another encouraging sign for the economy, suggesting growing business confidence.

Still, a private survey showed that Americans continue to cut back on gasoline purchases. MasterCard SpendingPulse reported Tuesday that the four-week average for U.S. retail gasoline demand fell by 4.2 percent year-over-year. That's the 38th week in a row that gasoline demand fell.

Gas pump prices slipped by less than a penny Tuesday to a national average of $3.269 per gallon, according to AAA, Wright Express and Oil Price Information Service. A gallon of regular is about 15 cents cheaper than a month ago and 29 cents cheaper than a year ago.

In other energy trading, heating oil rose 3.27 cents to finish at $2.9288 per gallon, and gasoline futures increased by 6.18 cents to end at $2.6254 per gallon. Natural gas rose 2.5 cents to finish the day at $3.279 per 1,000 cubic feet.

'Grim new precedent': Dozens killed at Afghan shrine

Twin blasts at Afghan shrines on a Shiite holy day have killed dozens. ITN's Paul Davies reports.

By NBC News, msnbc.com staff and news services

KABUL, Afghanistan -- A suicide bomber struck a crowd of Shiite worshippers who packed a Kabul mosque Tuesday to mark a holy day, killing at least 56 people, and a second bombing in another city killed four more Shiites. They were the first major sectarian assaults since the fall of the Taliban a decade ago.?

A Pakistan-based militant?group?claimed responsibility for the attack.

The attacker blew himself up in the midst of a crowd of men, women and children. The mosque had been packed with worshippers and many who could not fit inside were?outside the building.


The blast came shortly after a bicycle bomb?near a mosque in the?northern city of?Mazar-i-Sharif killed at least four people and wounded 21.?Another?bomb in a motorcycle exploded in the southern city of Kandahar on Tuesday afternoon, injuring six people, but police said that attack did not target Shiites.

Afghanistan has a history of tension and violence between Sunnis and the Shiite minority, but while such attacks have become commonplace in neighboring Pakistan and parts of the Middle East such as Iraq, they have not occurred in Afghanistan.

"Afghanistan has been at war for 30 years and terrible things have happened, but one of the things that Afghans have been spared generally has been what appears to be this kind of very targeted sectarian attack," Kate Clark, from the Afghanistan Analysts Network, told?Reuters.?"We don't know who planted the bomb yet and it is dangerous to jump to conclusions but if it was Taliban, it marks something really serious, and dangerous, and very troubling."?

Updated at 10:40 a.m. ET: Lashkar-e-Jhangvi al-Alami, a Pakistan-based militant organization, has claimed responsibility for the Kabul suicide attack. In a call to NBC News,?someone who claimed to be a spokesman for the group?said they had succeeded in their mission to attack Shiites. "It is the first time that?someone outside of Afghanistan has claimed responsibility for?a?attack in the country," NBC News' Mushtaq Yusufzai said.

Three coordinated suicide bombings across Afghanistan have killed at least 58 people, making the attacks the worst on civilians there in more than a decade.? NBC's Atia Abawi reports.

Updated at 8:50 a.m. ET:? The Ministry of Interior said 55 were killed in Kabul?? including two women and four children. Sayed Kabir Amiri, who is in charge of Kabul hospitals, told the Associated Press that more than 160 were wounded in the blast. Police confirm that a second bomb was defused in Mazar-i-Sharif near the one that blew up.

Updated at?7:05 a.m. ET: A Taliban spokesman tells Reuters that the group did not carry out the Kabul or Mazar-i-Sharif attacks.

"People were killed by the enemy's un-Islamic and inhuman activity," Zabihullah Mujahid?writes in an emailed statement. He?adds that the?Taliban "strongly condemns such a cruel, indiscriminate and un-Islamic attack."

Updated at 6:30 a.m. ET: Gareth Price,?a senior research fellow at?London-based?think tank Chatham House, says the?attacks may have come now because Afghan and Western forces aren't the easy targets they once were.

"Shia shrines are a softer target than foreign troops or the Afghan army," he tells msnbc.com.

However,?discrimination against?Shiites?--? and in particular the largely Shiite Hazaras --? has deep roots in Afghan history. "All the groups pick on the Hazaras," Price says.

Updated at 6:25 a.m. ET: Citing an official with Afghanistan's health ministry, NBC News reports that the Kabul shrine blast killed 54 people and injured 150 others.

Updated at 5:55 a.m. ET: Afghan officials tell The Associated Press that the death toll in Kabul?suicide bombing has reached 48.?Mohammed Zahir, chief of the Kabul Criminal Investigation Department, adds that more than 100 people were wounded.

Updated at 5:15 a.m. ET: "The shrine's loudspeaker continued to blast a recitation of the Quran as ambulances carried bodies and wounded away," The Associated Press reports.?It adds that the Abul Fazl shrine is located close to the palace where President Hamid?Karzai lives.?Its blue minaret is one of Kabul's better known landmarks.??

Updated at 4:55 a.m. ET:?Britain's Telegraph newspaper reportsthat?"Shiites were banned from marking Ashoura in public under the Taliban who ruled Afghanistan until 2001. This year, there are more Ashoura monuments around the city than usual including black shrines and flags."

Updated at 4:35 a.m. ET: Jonathan Boone (@jon_boone), a Kabul-based correspondent for The Guardian, tweetsquoting US General John Allen as describing the attack as "the latest example of the insurgents' blatant disregard for human life."

Updated at 4:25 a.m. ET:? Mohammad Bakir Shaikzada, the top Shiite cleric in Kabul, says that Shiites haven't been attacked in decades in Afghanistan.?"This is a crime against Muslims during the holy day of Ashoura. We Muslims will never forget these attacks. It is the enemy of the Muslims who are carrying them out," he said. He says he does not know who could have carried out such an attack.

Updated at 4:15 a.m. ET: Afghan President Hamid Karzai says it is first time that "terrorism" of this kind has occurred in the country on such a religious day, Reuters reports.

Updated at 4:10 a.m. ET:?Ahmad Shuja (@ahmadshuja),?director of Foundation for Afghanistan, tweets: "My hunch: Today's attacks WON'T, per se, touch off chain of sectarian violence. No Shiite group organized enough or duly experienced."

Updated at 4:00 a.m ET: NBC News cites a health official as saying that at least 50 people were injured in the Kabul blast.

Updated at 3.55 a.m. ET: Mohammad Zahir, head of Kabul's Criminal Investigation Department,?tells Reuters?that he?counted up to 20 bodies at a Kabul hospital, and expected the toll to rise following the explosion at a Shiite shrine in the Afghan capital. A?second attack near the main mosque in the northern city of Mazar-i-Sharif?killed four people and injured 17 others.

Reuters journalists Mirwais Harooni and?Emma Graham-Harrison?point out that although "Afghanistan has a history of tension and violence between Sunnis and the Shiite minority ... since the fall of the Taliban the country had been spared the large-scale sectarian attacks that have troubled neighboring Pakistan. The noon bomb in a riverside shrine, in the heart of old Kabul, appears to set a grim new precedent."

Updated at 3:47 a.m. ET:?At least?34 people were killed on Tuesday after blasts hit Shiite shrines in Afghanistan during the festival of Ashoura,Al Jazeera English reports citing local media reports and police.

Published at 3:30 a.m. ET: A blast at a shrine in Afghanistan's capital during the Shiite festival of Ashoura killed up to 24 people Tuesday, according to reports.

Meanwhile, four others were killed in the northern city of Mazar-i-Sharif when a bomb on bicycle exploded, Reuters said. The victims included a soldier.

The Kabul explosion was caused by a suicide bomber, Al Jazeera reported. It put the death toll at 24.

However, Hashmatullah Stanekzai, a spokesman for Kabul police, told the Associated Press that it wasn't clear if the explosives were planted in the shrine or if a suicide bomber was behind the attack.

The AP reported that at least 15 had been killed in the attack on the shrine, where worshippers were gathering for Ashoura, the Shiite Muslim holiday marking the death of Hussein, the grandson of Prophet Muhammad.

NBC News, msnbc.com staff, the Associated Press and Reuters contributed to this report.

Iran says oil would go over $250 if exports banned (Reuters)

TEHRAN (Reuters) ? Iran warned the West on Sunday any move to block its oil exports would more than double crude prices with devastating consequences on a fragile global economy.

"As soon as such an issue is raised seriously the oil price would soar to above $250 a barrel," Foreign Ministry spokesman Ramin Mehmanparast said in a newspaper interview.

The comments come as Iran strives to contain international reaction to the storming of the British embassy last week, a move which drew immediate condemnation from around the world and may galvanize support for tougher action against Tehran.

Washington and EU countries were already discussing measures to restrict oil exports after the United Nations nuclear watchdog issued a report in November with what it said was evidence that Tehran had worked on designing an atom bomb.

Iran says its nuclear program is entirely peaceful.

The U.S. Senate voted on Thursday to penalize foreign financial institutions that do business with Iran's central bank

-- which takes payment for the 2.6 million barrels Iran exports a day. The European Union is considering a ban -- already in place in the United States -- on Iranian oil imports.

So far neither Washington nor Brussels has finalized its move against the oil trade or the central bank amid fears of the possible impact on the global economy of restricting oil flows from the world's fifth biggest exporter.

But the British embassy attack dragged relations with Europe to a long-time low and Iran is now facing rising rhetoric about a direct hit on its main source of foreign earnings.

Until recently, Iran had dismissed as ineffective mounting sanctions aimed at forcing it to halt its nuclear activities. Mehmanparast's comments show a more defensive stance.

"No one welcomes the sanctions, we know that sanctions create obstacles, but we want to say we will overcome these obstacles," Mehmanparast told Sharq daily.

"Imposing sanctions on oil and gas is among the sanctions that, if one wants to do that, the consequences should be fully considered before taking any action," Mehmanparast said.

"I do not think the situation in the world and especially in the West today is prepared enough to raise such discussions."

Britain's embassy in Tehran was ransacked on Tuesday after London announced unilateral sanctions on Iran's central bank. London evacuated staff, closed the embassy and the biggest EU states withdrew their ambassadors in protests.

Rising tensions were enough to push up crude prices with ICE Brent January crude up 95 cents on Friday to settle at $109.94 a barrel.

Mehmanparast warned the EU on Saturday to avoid tying itself to British interests.
