Mystery Object Impacts Jupiter


CNN) -- Jupiter is sporting a new scar after a mystery object hit the gaseous planet this week, NASA scientists say.

An amateur astronomer in Australia noticed the new mark on the planet Sunday and tipped off scientists at NASA's Jet Propulsion Laboratory (JPL) in Pasadena, California, who then confirmed it was the result of a new impact, NASA said.

It's not clear what the object was that crashed into Jupiter's poisonous atmosphere.

Glenn Orton, a JPL scientist, told the magazine New Scientist that it could have been a block of ice from somewhere in Jupiter's neighborhood, or a wandering comet that was too faint for astronomers to have detected before impact.

"We were extremely lucky to be seeing Jupiter at exactly the right time, the right hour, the right side of Jupiter to witness the event. We couldn't have planned it better," Orton said in a NASA interview.

Scientists also don't know how large the object was, but the impact scar it created is about the same size as Earth, JPL astronomer Leigh Fletcher told the magazine.

Apollo 11

Apollo 11: "

Almost lost in the hoopla celebrating the 40th anniversary of the first human landing on the Moon is the fact that astronauts and cosmonauts are at work on the International Space Station - together.

On that summer night in 1969, Neil Armstrong and Buzz Aldrin's steps on the Moon marked the finish line for the Cold War space race. Kennedy's promise had been kept, and the U.S. had won. There wasn't a question of partnership in those days.

Seven astronauts took off last Wednesday in the space shuttle Endeavour from the same launch pad that sent Armstrong, Aldrin and command module pilot Michael Collins toward their rendezvous with history in and over the lunar Sea of Tranquility. Some of the others in orbit today lifted off in Russian Soyuz capsules from the same launch pad in Kazakhstan where Yuri Gagarin started the human adventure in space on April 12, 1961.

The combined shuttle and station crews have been busy since Endeavour docked, finishing up the Japanese laboratory module and getting the station ready for the day when space shuttles are no longer flying. Overall there are 13 space travelers on the ISS right now -- two each from Russia and Canada, one from Japan, one from Belgium and nine from the U.S. For the first time, all of the station's partner agencies are represented on board.

Every day before the station crew goes to bed the controllers on the ground take turns giving them any last-minute instructions or receiving final reports from orbit. The call signs of that daily tagup -- passed from west to east -- are literally a trip around the world.

It starts in Houston, which was the the first word spoken from the Moon. From there it goes to Huntsville, Ala., where many of the science payloads are controlled; to Munich, where Europe's Columbus lab is managed; to Moscow; to Tsukuba, Japan, home of the Kibo ground crew. Sometimes there are calls to St. Hubert, Quebec, where the Canadian-built robotics are monitored, and Toulouse, France, flight control center for the European Space Agency's Automated Transfer Vehicle.

Yesterday Brian Smith, the first-shift lead ISS flight director in Houston, commented on the Apollo 11 landing as he stopped by to brief reporters on the day's events.

'Back when we landed on the Moon, it was pretty much two countries involved and obviously they weren't working together,' he told the handful of journalists following the mission, a tiny fraction of the press mob that covered NASA operations 40 years ago. 'One was trying to beat the other in accomplishments for manned space. And now you look at what happens when the countries team up together. We can do so much more and set an example for the rest of the world on exactly how much you can accomplish when you work together. And we can serve as a model for countries working together in a peaceful and a productive way.'

The Apollo program was one of the premier feats in the history of engineering. So, in my view, is the assembly on orbit of the ISS, but with a tremendous dose of diplomacy added in. You could say that the lunar landings were really an act of war, albeit a cold one, in the sense Clausewitz meant when he said war is a continuation of politics by other means. Assembling the ISS is the opposite of that, and Brian Smith hit the nail right on the head about it.

With the space race won, the U.S. quickly retreated from the Moon. It's far from certain that NASA will go back there anytime soon, given other priorities on the U.S. agenda today. But it will be harder to retreat from the ISS. Humans have lived there continuously for almost nine years now, and are only beginning to reap the engineering lessons and scientific results it was built to deliver.

Certainly that is not to discount the courage and imagination that went into Apollo, or to ignore the foundation it set for future spaceflight. In just one example, the astronauts spacewalking outside the station today learned their stuff underwater. In doing so they were applying a training technique that Aldrin -- a scuba enthusiast -- proposed after Gemini-astronaut Ed White and other early spacewalker had trouble maneuvering in zero-g.

'Everything we've accomplished with the space station is built upon what was done in the Mercury, Gemini and Apollo programs, and even the Apollo-Soyuz Test Program following that and then Skylab,' Smith said. 'We built on that experience.'

The consoles at Mission Control Center - Houston and its counterpart in the Moscow suburbs are filled with idealistic young engineers like Smith. They have a different life experience than their predecessors, and they are finding important new ways to work together 'in a peaceful and productive way.'

'I wasn't born yet when we landed on the Moon, so I don't have a first-hand recollection and I can't tell you what I was feeling at the time or what my memories were,' Smith said in response to a question from Gina Sunseri of ABC News. 'They don't exist.'

I was a witness to this magnificent event.

Looking back - we were really very privileged to live in that thin slice of history where we changed how man looks at himself and what he might become and where he might go.

U.S.-based hotels hit by bombs in Jakarta

U.S.-based hotels hit by bombs in Jakarta: "Blasts hit two luxury hotels this morning in Jakarta, Indonesia, killing at least nine people in what the country's president called a terrorist attack. Officials said more than 50 people were injured at the Ritz-Carlton and J. W. Marriott hotels, which are based in the U.S. The U.S. State Department says several American citizens were hurt.

12 Afghan insurgents die in latest strike


12 Afghan insurgents die in latest strike: "KANDAHAR, Afghanistan — International troops and Afghan police killed 12 Taliban insurgents in a gunbattle in southern Afghanistan, police said Sunday.

The joint force attacked a compound north of the capital of Uruzgan province where the militants were hiding Saturday evening, sparking the fighting, police spokesman Mohammad Musa said. He said no Afghan police or international troops were killed.In eastern Kunar province, meanwhile, one civilian was killed and five wounded when shelling from a gunbattle between insurgents and Afghan and international forces hit a house.Provincial Police Chief Gen. Abdul Jalal Jalal said everyone in the house initially survived Saturday’s blast, but one man died from his injuries after being rushed to a hospital. Jalal said it was unclear which side fired the shots that hit the house.Also Saturday, at least six police officers were killed by roadside bombs — two in southern Helmand province and at least four south of Kabul in Logar province, officials said.

In Logar, the officers were driving in a private car in Charkh district when the explosion hit, said provincial police chief Gen. Mustafa Mosseini.NATO forces, who secured the site and treated one wounded officer, said in a statement that four police were killed. Mosseini said five officers died.The bombing in Helmand took place Saturday night in Lashkar Gah, the provincial capital, killing two police and wounding three, said Dawood Ahmadi, the governor’s spokesman.Police officers are regular targets of Taliban and other insurgents in Afghanistan. Mosseini said the officers had been traveling in a civilian car in order to avoid drawing the attention of potential attackers.In another gunbattle in eastern Paktia province between insurgents and Afghan police, two militants and one police officer were killed, said Rahullah Samon, a spokesman for the governor.———Associated Press writer Amir Shah contributed to this report from Kabul."
