Saturn mission: Cassini instrument learns new tricks

Dec. 20, 2012 ? For seven years, a mini-fridge-sized instrument aboard NASA's Cassini spacecraft reliably investigated weather patterns swirling around Saturn; the hydrocarbon composition of the surface of Saturn's moon Titan; the aerosol layers of Titan's haze; and dirt mixing with ice in Saturn's rings. But this year the instrument -- the visual and infrared mapping spectrometer (VIMS) -- has been testing out some new telescopic muscles.

This Friday, Dec. 21, the spectrometer will be tracking the path of Venus across the face of the sun from its perch in the Saturn system. Earthlings saw such a transit earlier this year, from June 5 to 6. But the observation in December will be the first time a spacecraft has tracked a transit of a planet in our solar system from beyond Earth orbit.

Cassini will collect data on the molecules in Venus's atmosphere as sunlight shines through it. But learning about Venus actually isn't the point of the observation. Scientists actually want to use the occasion to test the VIMS instrument's capacity for observing planets outside our solar system.

"Interest in infrared investigations of extrasolar planets has exploded in the years since Cassini launched, so we had no idea at the time that we'd ask VIMS to learn this new kind of trick," said Phil Nicholson, the VIMS team member based at Cornell University, Ithaca, N.Y., who is overseeing the transit observations. "But VIMS has worked so well at Saturn so far that we can start thinking about other things it can do."

VIMS will be able to complement exoplanet studies by space telescopes such as NASA's Hubble and Spitzer space telescopes. VIMS scientists are particularly interested in investigating atmospheric data -- such as signatures of methane -- from far-off star systems in near-infrared wavelengths.

The pointing has to be very accurate to get one of those extrasolar planets in VIMS's viewfinder, but the instrument has had lots of practice pointing at other stars. Earlier this year, VIMS obtained its first successful observation of a transit by the exoplanet HD 189733b. Scientists want to improve these observations by reducing the amount of noise in the signal.

In April, VIMS demonstrated another kind of flexibility by turning its eyes to the warm fissures slashing cross the surface of Saturn's moon Enceladus. VIMS is particularly good at taking thermal data in temperatures around minus 100 degrees Fahrenheit (200 kelvins). So while it is good at tracking hotspots and turbulent clouds on Saturn, VIMS is generally unable to detect thermal emission from Titan, the icy satellites or the rings, since their temperatures are much colder than that.

But the fissures on Enceladus, which scientists have called tiger stripes, are just hot enough for VIMS to detect heat coming from them.

"For the first time, we were able to see that the jets coming from the surface of Enceladus originated in very small, very hot spots," said Bonnie Buratti, a VIMS scientist at NASA's Jet Propulsion Laboratory, Pasadena, Calif. "This new observation is good evidence for liquid water underneath the surface."

VIMS is one of 12 instruments on Cassini, which launched in 1997 and began orbiting Saturn in 2004. "We built Cassini to be hardy, and we're pleased that the spacecraft has been weathering the extreme conditions of the Saturn system remarkably well," said Robert Mitchell, Cassini program manager at JPL. "It isn't too tired to try something new."

The Cassini-Huygens mission is a cooperative project of NASA, the European Space Agency and the Italian Space Agency. The Jet Propulsion Laboratory, a division of the California Institute of Technology, Pasadena, manages the mission for NASA's Science Mission Directorate, Washington, D.C. The visual and infrared mapping spectrometer team is based at the University of Arizona, Tucson.

WASHINGTON (AP) ? Three State Department officials resigned under pressure Wednesday, less than a day after a damning report blamed management failures for a lack of security at the U.S. diplomatic mission in Benghazi, Libya, where militants killed the U.S. ambassador and three other Americans on Sept. 11.

The resignations came as lawmakers expressed anger and frustration over the findings of an independent review panel, and the State Department struggled to find a balance between protecting its diplomats while allowing them to do their jobs connecting with people in high-risk posts.

An Obama administration official said Eric Boswell, the assistant secretary of state for diplomatic security, Charlene Lamb, the deputy assistant secretary responsible for embassy security, and an unnamed official with the Bureau of Near East Affairs, had stepped down. The official spoke on condition of anonymity because he wasn't authorized to discuss personnel matters publicly.

The department declined immediate comment on the resignation of the officials whose decisions had been criticized in the unclassified version of the Accountability Review Board's report that was released late Tuesday.

The board's co-chairman, retired Adm. Mike Mullen, told reporters that the board had not determined that any officials had "engaged in willful misconduct or knowingly ignored his or her responsibilities,"

But Mullen, a former Joint Chiefs of Staff chairman, added, "We did conclude that certain State Department bureau level senior officials in critical levels of authority and responsibility in Washington demonstrated a lack of leadership and management ability appropriate for senior ranks in their responses to security concerns posed by the special mission."

Mullen said the mission's security fell through bureaucratic cracks caused in part because buildings were categorized as temporary. The report said that budget constraints had caused some officials to be more concerned with saving scarce money than in security.

Co-chairman Thomas Pickering, a retired ambassador, said the personnel on the ground in Benghazi had reacted to the attack with bravery and professionalism. But, he said, the security precautions were "grossly inadequate" and the contingent was overwhelmed by the heavily armed militants.

"They did the best they possibly could with what they had but what they had wasn't enough," Pickering said.

Pickering and Mullen spoke shortly after briefing members of Congress in private. Lawmakers from both parties emerged from the sessions with harsh words for the State Department.

"My impression is the State Department clearly failed the Boy Scout motto of be prepared," said Sen. John Barrasso, R-Wyo.

"They failed to anticipate what was coming because of how bad the security risk already was there. ... They failed to connect the dots," he said. "They didn't have adequate security leading up to the attack and once the attack occurred, the security was woefully inadequate."

Rep. Adam Schiff, a member of the House intelligence committee, said security was "plainly inadequate, intelligence collection needs to be improved, and our reliance on local militias was sorely misplaced.

"These are not mistakes we can afford to make again," he said.

The House intelligence committee chairman, Rep. Mike Rogers, R-Mich., said the report laid bare "the massive failure of the State Department at all levels, including senior leadership, to take action to protect our government employees abroad," and complained that no one was being held accountable.

Rogers also said he was dissatisfied with the lack of progress in finding the attackers.

Lamb, the deputy assistant secretary of state for diplomatic security who was in charge of embassy protection, testified in October before the House Oversight and Government Reform Committee and defended the security measures.

"I made the best decisions I could with the information I had," Lamb said at the time. "We had the correct number of assets in Benghazi at the time of 9/11."

She also told Rep. Dan Burton, R-Ind., that she rejected requests for more security in Benghazi, instead training "local Libyans and army men" to provide security, a policy in force at U.S. diplomatic facilities around the world.

Pickering and Mullen set the stage for public hearings set for Thursday on Capitol Hill., Scheduled to testify were Deputy Secretary of State William Burns, who is in charge of policy, and Deputy Secretary of State Thomas Nides, who is in charge of management.

Secretary of State Hillary Rodham Clinton was to have appeared at Thursday's hearings, but canceled after fainting and sustaining a concussion last week while recovering from a stomach virus. Clinton is under doctors' orders to rest.

Senate Republicans and Democrats said they hoped Clinton would testify on the Hill even though she is planning to step down from her Cabinet post.

In a letter that accompanied the transmission of the report to Capitol Hill, Clinton thanked the board for its "clear-eyed, serious look at serious systemic challenges" and said she accepted its 29 recommendations to improve security at high-threat embassies and consulates.

She said the department had begun to put in place some of the recommendations. They include increasing by several hundred the number of Marine guards stationed at diplomatic missions throughout the world; relying less on local security forces for protection at embassies, consulates and other offices; and increasing hiring and deployment of highly trained Diplomatic Security agents at at-risk posts.

Clinton agreed with the panel's finding that Congress must fully fund the State Department's security initiatives. The panel found that budget constraints in the past had led some management officials to emphasize savings over security, including rejecting numerous requests from the Benghazi mission and the embassy in Tripoli for enhanced protection.

House and Senate negotiators working on a defense bill agreed on Tuesday to fund 1,000 more Marines at embassy security worldwide.

The report singled out the Bureau of Diplomatic Security and the Bureau of Near East Affairs for criticism. It said there was a lack of cooperation and confusion over protection at the mission in Benghazi, a city in eastern Libya that was relatively lawless after the revolution that toppled Libyan leader Moammar Gadhafi.

But it broke little new ground about the timeline of the Benghazi attack. Killed were U.S. Ambassador Chris Stevens, information specialist Sean Smith, and former Navy SEALs Glen Doherty and Tyrone Woods ? who were contractors working for the CIA. Stevens was the first U.S. ambassador killed since 1988.

The board determined that there had been no immediate, specific tactical warning of a potential attack on the 11th anniversary of Sept. 11, 2001. But the report said there had been several worrisome incidents before to the attack that should have set off warning bells.

It did confirm, though, that contrary to initial accounts, there was no protest outside the facility.

In the immediate aftermath of the attack, administration officials linked the attack to the spreading protests that had begun in Cairo earlier that day over an American-made, anti-Islamic film. Those comments came after evidence already pointed to a distinct militant attack in Benghazi.

U.N. Ambassador Susan Rice appeared on numerous TV talk shows the Sunday after the attack and used the administration talking points linking it to the film. An ensuing brouhaha in the heat of the presidential campaign eventually led her to withdraw her name from consideration to replace Clinton as secretary of state in President Barack Obama's second term.

Sen. Jim Inhofe, R-Okla., emerging from the Senate briefing on the report, kept up the congressional criticism of Rice.

"Now we all know she had knowledge. She knew what the truth was. It was a cover-up," he said.

While criticizing State Department management in Washington along with the local militia force and contract guards that the mission depended on for protection, the report said U.S. personnel on the ground in Benghazi "performed with courage and readiness to risk their lives to protect their colleagues in a near-impossible situation."

It said the response by Diplomatic Security agents on the scene and CIA operatives at a nearby compound that later came under attack itself had been "timely and appropriate" and absolved the military from any blame. "There was simply not enough time for armed U.S. military assets to have made a difference," it said.

The report also discounted speculation that officials in Washington had refused appeals for additional help after the attack had begun.

The report said the evacuation of the dead and wounded 12 hours after the initial attack was due to "exceptional U.S. government coordination and military response" that helped save the lives of two seriously wounded Americans.

Austin Dillon tests at Mid-Ohio ahead of the Car Course?s NASCAR debut in 2013 ? NASCAR news

The 22-year-old NASCAR Nationwide driver Austin Dillon got a taste of driving at Mid-Ohio, the race course which will be hosting Nationwide Children?s Hospital 200 on August 17 next year. 2013 Children?s Hospital 200 will be the first NASCAR event to be held at Mid-Ohio.

The Mid-Ohio test was aimed at two things. To get information about the performance of Chevrolet Camaro, the car that Dillon will be driving in 2013, on 13 turns of the Mid-Ohio road course and to get some seat time for Dillon.

?We came over here mainly to understand the basic characteristic of what we need in a Nationwide Series car on this track,? racing veteran Max Papis said. ?It?s something I really pushed Richard Childress Racing to do, especially for Austin to get acquainted to the track and learn his way around.?

Mid-Ohio, the 2.4-mile road course in Lexington awaits the Nationwide Series drivers scheduled to race at Mid-Ohio in August next year. According to Jesse Ghiorzi, Mid-Ohio spokesman, with only 12 more days to go until the start of 2013, Dillon became the first and may very well be the last driver to have made a test run in Lexington because NASCAR drivers are not allowed to do test runs at tracks which are on the current year?s schedule.

Ghiorzi further added that Mid-Ohio may make an exception from NASCAR?s rule that disallows drivers from making in-year test runs at on-schedule tracks for the current year because 2013 will be the first year a NASCAR race is being held at Mid-Ohio. If that happens, the tests could include multiple cars which in turn would make it easier for drivers to get a feel of the 13 turns and 150-foot elevation changes at the Mid-Ohio race course.

It is a common fact that every track has its own conditions and the challenges that each track presents for the drivers is different than the other.

According to the Mid-Ohio spokesman, ?Any kind of road course can have different types of turns, speeds and elevations,? Ghiorzi said. ?They all are a little bit different.?

So it will be in the best interest of the sport if in-year tests are allowed by NASCAR at Mid-Ohio.
