ISS astronauts land safely in Kazakhstan

MOSCOW (AFP)– A Soyuz space capsule carrying an Italian, a Russian and an American back from the International Space Station (ISS) has landed safely in Kazakhstan, Russian mission control said Tuesday.

"They have landed and all is well. They landed at approximately 0627 (02:27 GMT)," a spokesman for mission control told AFP.

Russia's Dmitry Kondratyev, Paolo Nespoli of the European Space Agency, and NASA's Catherine Coleman landed in the correct location to the east of the town of Jezkazgan after spending 159 days in space, mission control said in a statement.

"All the operations in leaving orbit and landing went according to plan," mission control said.

Live television footage showed the astronauts sitting wrapped in blankets on the sunny steppe after emerging from the capsule. Coleman was shown smiling and chatting to a cosmonaut retrieval worker while holding a bouquet of flowers.

Tornado kills one, damages 200 houses in Kansas

KANSAS CITY (Reuters)– Tornadoes overnight in northeast Kansas killed one person and damaged some 200 homes, and resulted in a state of emergency being declared for 16 counties, state officials said on Sunday.

Elsewhere in the country, towns along the lower Mississippi River were coping with floodwaters, and parts of the Midwest and Southeast faced the threat of violent thunderstorms, hail and strong winds.

In Kansas the known tornado damage was centered around the town of Reading, said Kansas Division of Emergency Management spokeswoman Sharon Watson.

Initial reports"indicate there are 200 homes in the town and surrounding community that have some type of damage ranging from minor to severe ... Another 20 homes have been destroyed," she told Reuters by phone.

A separate statement from the Emergency Management Division said most of the destroyed homes were in the town.

Gail Lewis was on her way to Reading to visit friends when the tornado struck. She said she arrived in town before most responders and saw downed trees and damaged homes.

"Our church had one side completely blown out," said Lewis, whose father is pastor of the Reading First Baptist Church.

"People were in shock last night," Lewis said."It's a devastating blow for such a small community."

Reading residents were given access to town until 6 p.m. Sunday to check on property and then tentatively will be allowed to return at 9 a.m. Monday, said Tammy Vopat, spokeswoman for the Lyon County Emergency Management office.

A fatality had also been confirmed early on Sunday morning from the twister that struck at around 9:15 p.m. on Saturday night in the town of around 250 people and the surrounding area. There were reports of at least five injuries.

"Our thoughts and prayers are with the family of the victim and everyone impacted by this storm," Governor Sam Brownback was quoted as saying in the Emergency Management statement.

It said that earlier in the evening a tornado reportedly touched down in Jefferson County at a campground. A mobile home was destroyed and an elderly couple trapped inside until emergency responders could clear the debris. The couple was uninjured.

Damage from tornadoes and storms in other parts of the state was still being assessed, Watson said, but included broken windows in cars and buildings, mostly from hail and strong winds.

There was potential for more storms on Sunday, she said.

Elsewhere in the nation, AccuWeather.com meteorologists have forecast"violent" thunderstorms across the Mississippi River and Ohio River valleys on Sunday, with most of the strongest storms beginning in the afternoon.

Central Texas, central Arkansas, northern Mississippi and western Tennessee are also expected to experience severe weather.

Meteorologists said the main threats will be large hail and damaging wind gusts, but flash flooding and isolated tornadoes also could be problems.

"Cities under the gun include St. Louis, Springfield, Chicago, Dallas and Abilene," an AccuWeather.com report said.

"Fairly significant" rains are predicted to continue in the Ohio and Mississippi river valleys during the next five days, said National Weather Service meteorologist Larry Vannozzi.

But the rains won't be as widespread or intense as the weeks of heavy downpours that contributed to the Mississippi River rising to historic levels, said Vannozzi.

The river, which hit record crests in Mississippi at Vicksburg and Natchez, will slowly inch downward at those gauges in the next few days and is unlikely to rise again as a result of the additional rain, Vannozzi said.

"It's just going to prevent it from getting better sooner," he said.

NASA Clears Shuttle Endeavour Heat Shield of Concerns

Space shuttle Endeavour's heat shield has been deemed safe for the ship's last landing thanks to imagery taken by its astronauts and sent down for study on Saturday.

"We're essentially clearing the vehicle for reentry at this point," said NASA's shuttle mission management team chair, LeRoy Cain.

Earlier this week, engineers and mission managers were able to clear six of seven areas of minor damage they had found dotting the right-side ofEndeavour's tile-covered underbelly. The damage was likely caused by debris, such as ice and insulating foam, that fell from the shuttle's external fuel tank during its launch May 16. {Photos of Space Endeavour's Final Launch}

Fuzzy photos of the seventh gouge, which straddled twothermal protection system(TPS) tiles, couldn't be analyzed to the same degree, so the shuttle astronauts were tasked with using cameras and sensors mounted at the end of a robotic arm inspection boom to get a close-up look at the site early on Saturday morning.

The ding is 2.43 inches (6.17 cm) by 2.95 inches (7.49 cm) wide, and 0.89 inches (2.26 cm) deep.

By Saturday afternoon, imagery and tile experts at NASA's Johnson Space Center in Houston had processed the newly-downlinked data, even creating a physical 3D model of the divot.

"With the data, to include the laser data that the team was able to acquire from the focused inspection, the analyses team went back and essentially what they did was verify how much tile was still in the cavity, because of course it is more important what remains than it is what is gone," said Cain."What we're interested in is protecting the structure underneath the tile and the associated systems."

The team found the damage was well within margins of safety, and advised that the shuttle was safe to return to Earth. Endeavour, flying its final spaceflight, is scheduled to make its last landing from space on June 1, weather permitting. The shuttle crew has been delivering a $2 billion astrophysics experiment and a shipment of spare supplies to the International Space Station. {Most Memorable Shuttle Missions}

"So with that we've cleared the TPS," said Cain."The vehicle is otherwise in great shape as well. It continues to perform outstanding."

Endeavour Shuttle Crew to Inspect Damaged Heat Shield Tile

Astronauts on the space shuttle Endeavour will take another look at their spacecraft's heat shield this weekend to inspect a damaged tile on the orbiter's vital heat shield, NASA managers said Friday (May 20).

Endeavour's crew will spend about two hours on Saturday inspecting a ding in the black heat-resistanttiles lining the shuttle's underbelly, said LeRoy Cain, chair of Endeavour's mission managiement team, in a briefing. The survey, known as a focused inspection, should give engineers on Earth the data they need to clear Endeavour's heat shield of any remaining concerns for its eventual landing on June 1.

The ding is one of seven damage sites spotted in photo surveys of Endeavour's heat shield following the shuttle's final launch on Monday (May 16). It is about 3.2 inches (8.1 centimeters) long and 2.5 inches (6.4 cm), and located slightly aft of the Endeavour's rear right-side landing gear door. {Photos of Space Endeavour's Final Launch}

Cain said engineers have already cleared the rest of Endeavour's heat shield of any concerns, including the six other tile damage sites and heat shield panels along the orbiter's wings and nose cap. They are confident this follow-up inspection will clear the remaining ding, too, he added.

"There's nothing alarming here, and we're really not concerned," Cain said.

NASA has kept a vigilant eye on shuttle heat shield damage since 2003, when wing damage caused by falling fuel tank insulation during launch led to the loss of the shuttle Columbia during its return to Earth. Seven astronauts were killed.

Since then, every shuttle mission has included meticulous heat shield surveys just after launch and just before landing, with some extra time scheduled in for a focused inspection in case one is needed. {Most Memorable Shuttle Missions}

For Saturday's survey, Endeavour pilot Gregory H. Box will control the shuttle's robotic arm to position a 50-foot (15-meter) inspection pole tipped with a camera laser sensor just beneath the damage site. A digital camera will snap three close-up images while the laser instrument records data that will help analysts build a three-dimensional map of the damage.

"This is one that we feel pretty confident that we're going to be able to clear once we get some additional data," Cain said. An answer could be ready within 24 hours of the survey, he added.

Endeavour's six-astronaut crew is currently in the midst of a 16-day mission to the International Space Station to deliver a major astrophysics experiment along with other supplies and equipment.

The astronauts were planning to take some time off late Friday (actually the crew's"morning" due to a skewed overnight schedule) to rest up from the busy mission. The astronauts are also expecting aphone call from Pope Benedict XVIin the Vatican early Saturday morning to mark the fact that two Italian astronauts— station crewmember Paolo Nespoli and shuttle astronaut Roberto Vittori— are in space at the same time.

Those events should not be affected by Endeavour's extra heat shield inspection, Cain said.

"We're not losing any activities by doing this," he added.

Endeavour's current mission is NASA's 134th shuttle flight and the second-to-last flight before the 30-year-old program ends later this year. After Endeavour lands, NASA will fly onefinal mission on the shuttle Atlantisbefore shutting down the program. That flight is currently slated to lift off July 8.

NASA Studies Tile Damage on Shuttle Endeavour Heat Shield

HOUSTON— NASA engineers are taking a close look at several spots on the  space shuttle Endeavour's belly where its vital heat shield tiles were during the spacecraft's launch earlier this week.,

Endeavour blasted off Monday (May 16) to begin a 16-day trip to the International Space Station. It is the shuttle's last mission before the orbiter is retired to a museum. {Photos of Shuttle Endeavour's Final Launch}

The damaged spots are onEndeavour's heat shield, which protects the spaceship from the fiery temperatures it experiences when re-entering Earth's atmosphere.

Most likely, the damage will turn out to be of no consequence, NASA officials said, but for now they must continue to analyze the patches to make sure.

"I am not concerned about the damage that we're seeing here," LeRoy Cain, chair of Endeavour's mission management team, told reporters Thursday (May 19)."It's certainly not alarming, and the team is not concerned about it."

NASA has kept a close eye on the health of space shuttle heat shields during mission since the tragic 2003 loss of the shuttle Columbia. A piece of fuel tank debris damaged Columba's heat shield during launch, leading to the shuttle's destruction during re-entry. Seven astronauts were killed.

Since then, shuttle astronauts have conducted several in-space inspections of their spacecraft to make sure the vehicle is safe for re-entry. Several repair tools and techniques are also available, should they be needed.

The damage on Endeavour is not on the same scale as that during the Columbia accident.

Photos of Endeavour's heat shield taken during a routine inspection by shuttle astronauts after launch, as well as by the space station's crew before the shuttledocked at the orbiting labyesterday, revealed seven areas of damage, Cain said.

Of those seven spots, mission managers have already dismissed five of those since they pose no risk, Cain added. Mission managers are very close to clearing a sixth, he said.

But one area about 3.2 inches (8.1 centimeters) long and 2.5 inches (6.4 cm) wide may still pose a potential hazard, and requires further study to be sure.

It's possible NASA will need to have the Endeavour astronauts go forward with an extra heat shield inspection to gather better photos of the area for closer analysis. This activity, called a focused inspection, is relatively rare.

NASA has only had to conduct focused inspections four times since adding them as an optional activity to every shuttle mission following the Columbia shuttle accident.

"The team has not completed our assessments on this site, but the work we've done so far, we believe that we may need to do a focused inspection in order to get some fidelity," Cain said. The existing pictures of that area, he said"are kind of fuzzy."

Most likely, if such an inspection is necessary at all, it will be all that's needed to clear the last spot of any potential risk to the orbiter, Cain said.

"I feel pretty confident that if in fact were not able to clear it by the morning, when we get the focused inspection data that we'll be able to clear this problem and not have to do anything," he said.

If, however, it does turn out that the damaged area make the vehicle unsafe to fly back to Earth, NASA has options to fix it.

"We do have some repair capability," Cain said."Astronauts would go out with a gun-type applicator and we put some material in the cavity. We also have what's called tile overlay. We have a lot of confidence in both of those repair capabilities if we should need to use them."

Senate stops move to repeal Big Oil tax breaks

WASHINGTON (Reuters)– The Senate blocked a move by Democrats to repeal billions of dollars in tax breaks enjoyed by the biggest oil companies operating in the United States, but Majority Leader Harry Reid said that paring back the incentives would be included in an upcoming budget deal.

Democratic sponsors of the bill, which would have used the savings from ending the tax breaks to pay down$21 billion of the deficit in ten years, got only 52 of the 60 votes needed to proceed on the measure on Tuesday. The bill would have cut back tax breaks enjoyed by Exxon Mobil Corp, Chevron ConocoPhillips, BP and Shell Oil, the U.S. unit of Royal Dutch Shell.

Before the widely expected outcome, Reid said the issue would be included in a budget deal."I am confident before we finish our budget negotiations here in anticipation of raising the debt ceiling that will be part of it," Reid told reporters earlier on Tuesday.

Vice President Joe Biden is steering a deal between Democrats and Republicans to increase the debt limit and pare back spending that lawmakers hope reach before August 2.

Reducing the tax breaks that the companies have enjoyed for decades has long been a goal of President Barack Obama and his fellow Democrats. The call to do so has gotten louder ahead of next year's elections and as the big five oil companies made about$36 billion in profits during the first quarter of the year as oil prices rose to about$100 a barrel.

"The administration believes that, at a time when it is working with the Congress on proposals to reduce federal deficits, the nation cannot afford to maintain these wasteful subsidies," the White House said earlier on Tuesday.

On Wednesday Republicans in the Senate are expected to push a bill to open up offshore oil drilling, which they say has been locked up by Obama regulations after last year's BP oil spill in the Gulf of Mexico. But the measure faces an uphill battle in the Democratic-led Senate.

Environmentalists blasted Tuesday's outcome in the Senate.

"The Senate today had the chance to do right by American taxpayers," Frances Beinecke, the president of the Natural Resources Defense Council, said in a release.

"Instead, pressured by oil industry lobbyists and a misguided Republican leadership, it decided to continue to give tax breaks to highly profitable Big Oil companies that don't need any taxpayer incentives."

Student Balloon Photographs Shuttle Endeavour's Launch Into Orbit

A camera-toting balloon captured unique views of NASA's space shuttle Endeavour as it soared into space for the final time today (May 16), snapping pictures from the stratosphere as part of a student-led project.

The helium-filled balloon carrying the so-called"Senatobia-1" payload was launched near Gainesville, Fla. at 7:30 a.m. EDT (1130 GMT) this morning.Endeavour blasted offfrom NASA's Kennedy Space Center in Cape Canaveral, Fla. at 8:56 a.m. EDT (1256 GMT). The shuttle is now en route to the International Space Station on its 25th and final mission before it is retired. {See the Student Balloon Photo of Endeavour Launch}

"Senatobia-1 has multiple video and still cameras to catch Endeavour's climb into space," Quest for Stars officials said via Twitter.

The balloon's earlier launch time allowed the payload to be in position at an altitude of approximately 100,000 feet (almost 30,500 meters) to witness Endeavour's supersonic streak beyond the stratosphere. {Shuttle Endeavour Launch Photos: Mission STS-134}

The balloon was built and flown by students as part of a venture conducted by Quest for Stars, a non-profit educational organization, in coordination with the Challenger Center for Space Science Education and the Coalition for Space Exploration.

The intent of the balloon flight is to bring together students and citizens from across a broad range of backgrounds who would not normally have contact with a mission to the edge of space, organization officials said in a statement. {Video: Endeavour's Lift-0ff into History}

Endeavour's flight was the second shuttle launch a Quest for Stars balloon has observed. The group's"Robonaut-1" balloon snapped picturesof the space shuttle Discovery's launch from the edge of space in February 2011.

The payload of this balloon, Senatobia-1, takes its name from the city of Senatobia, Miss., which has long shared a special connection with Endeavour. Senatobia was one of two communities that originally suggested the name"Endeavour" as a possible name forNASA's youngest space shuttle, which was built as a replacement after Challenger was tragically lost in 1986.

In addition to carrying a still and video camera, a GPS and radio tracking devices, the balloon also toted signatures gathered from a large number of students in Senatobia wishing a speedy recovery for wounded Congresswoman Gabrielle Giffords, wife of Endeavour's STS-134 commander Mark Kelly. Giffords (D-Ariz.) suffered a gunshot wound to the head in a failed assassination attempt at a January constituent meeting in Tucson.

The balloon burst at high altitude and drifted back down to Earth as planned today, its mission complete. Recovery personnel grabbed it and reported that everything had apparently worked well.

"Recovery team reports Senatobia-1 Balloon payload recovered in'pristine' condition w/ all cameras still operating after mission to 95K+ ft," Quest for Stars officials tweeted today.
