    50 Years of Space Exploration

    It doesn't seem like much, but this week it has been 50 years since humans started to explore space.

    It all started on October 4, 1957 with the launch of Sputnik. As one of the historians said, 1000s years on if we were to ask a person what significant even had happened in the 20th century, they will say Sputnik. And yet, this anniversary that produced so much that we have right now, is not well known.

    Here are some of the videos about Sputnik

    MOSCOW (Reuters) - World space chiefs on Thursday celebrated 50 years since the launch of Sputnik, the first man-made satellite, marked the start of the space age.

    People across the planet gasped in 1957 when the Soviet Union fired the 87-kg (180-pound) Sputnik into orbit and took the lead in the Cold War space race with the U.S.

    "I am convinced that the Sputnik accomplishment by the Russian people was responsible for the creation of the American space program that I head today," NASA administrator Michael Griffin told space veterans at Russia's Academy of Science.

    The ceremony was one of a number commemorating the Sputnik anniversary in Russia. Earlier, military officials laid flowers at the Kremlin Wall grave of Sputnik mastermind Sergei Korolyov.

    "Without Sputnik there would have been no Apollo. Indeed when the space race of the 1960s was over, it may be said that we in America lost some of our own momentum," said Griffin, referring to the Apollo project, which put a man on the moon in 1969.

    The world would be very different today without the satellites that followed on from Sputnik and now ensure communications, help people find directions, spy on foes and track the weather across the globe.

    Although it would dictate the course of his life, top Russian top space scientist Alexander Basilevsky recalled being too busy celebrating his 20th birthday at a scientific camp in Siberia to be impressed when Sputnik beeped a signal to earth.

    He saw no practical use for it.

    "Of course we were drinking some vodka and singing, but when I heard this on the radio, I wasn't interested at all," he said.

    Enjoying his 70th birthday, Basilevsky explained how he spent the rest of his working life studying planetary surfaces.

    He helped pick the location for Russian robotic lunar landings in the 1960s and is now working on Russia's 2009 mission to the Martian moon of Phobos, the country's first major space project in over a decade.

    NEW MONEY

    Russia's space program went through a difficult period during the chaotic decade following the Soviet Union's collapse but now has a budget of 487 billion rubles ($19.5 billion) for the period from 2006-15.

    These days, Russia and the United States also cooperate on some aspects of space exploration. They signed a pact to use Russian technology on future NASA missions to seek water on the moon and Mars.

    Basilevsky and colleague Andrei Ivanov confirmed as "more or less" true the often-told story that at the height of the space race the United States spent millions developing a pen to work in space, while the Soviets settled for an ordinary pencil.

    "When you don't have much, you must be inventive and that's sometimes what drove our success," said Ivanov, laughing.

    Proudly displaying his row of Soviet-era medals, Efraim Akim, 78, remembered working on the 1966 Luna-9 mission, the first to succeed in making a soft landing on the moon and sending back photos

    Wistfully recalling the achievements in the early years of space exploration, Jean-Jacques Dordain, the director general of the European Space Agency, said a fresh spurt of discovery would entice another generation into space research.

    Other scientists looked as excited as teenagers at their first pop concert.

    "Sputnik changed my life though I was only born two years afterwards," said Dr David Greenspoon, a NASA scientist seconded to the European Space Agency for the Venus Express project.

    Rekindling something of the old spirit of competition, Boris Gryzlov, leader of Russia's biggest political party United Russia, demanded a big increase in the space budget.

    He also announced that a Russian MP and supermarket tycoon, Vladimir Gruzdev, 40, who in August planted a Russian flag on the North Pole seabed, would become the country's first space tourist this month.

    "Sputnik showed that going into space was something that was viable," said Ed Weiler, an astronomer who now directs NASA's Center in Greenbelt, Md.

    "It inspired an entire generation of kids in this country to become scientists and engineers and it was that generation that gave us all the technology that we're so happy to use today — communication satellites, Blackberries, computers, etc.," Weiler said.

    Re: 50 Years of Space Exploration

    MOSCOW - When Sputnik took off 50 years ago, the world gazed at the heavens in awe and apprehension, watching what seemed like the unveiling of a sustained Soviet effort to conquer space and score a stunning Cold War triumph. if(window.yzq_d==null)window.yzq_d=new Object(); window.yzq_d['PsnNfULEYrA-']='&U=13bkavis6%2fN%3dPsnNfULEYrA-%2fC%3d619213.11492542.12049046.1414694%2fD%3dLREC%2fB%3d4940782';

    But 50 years later, it emerges that the momentous launch was far from being part of a well-planned strategy to demonstrate communist superiority over the West. Instead, the first artificial satellite in space was a spur-of-the-moment gamble driven by the dream of one scientist, whose team scrounged a rocket, slapped together a satellite and persuaded a dubious Kremlin to open the space age.

    And that winking light that crowds around the globe gathered to watch in the night sky? Not Sputnik at all, as it turns out, but just the second stage of its booster rocket, according to Boris Chertok, one of the founders of the Soviet space program.

    In a series of interviews in recent days with The Associated Press, Chertok and other veterans told the little-known story of how Sputnik was launched, and what an unlikely achievement it turned out to be.

    Chertok couldn't whisper a word about the project through much of his lifetime. His name, and that of Sergei Korolyov, the chief scientist, were a state secret. Today, at age 95 and talking to a small group of reporters in Moscow, Chertok can finally give full voice to his pride at the pivotal role he played in the history of space exploration.

    "Each of these first rockets was like a beloved woman for us," he said. "We were in love with every rocket, we desperately wanted it to blast off successfully. We would give our hearts and souls to see it flying."

    This very rational exuberance, and Korolyov's determination, were the key to Sputnik's success.

    So was happenstance.

    As described by the former scientists, the world's first orbiter was born out of a very different Soviet program: the frantic development of a rocket capable of striking the United States with a hydrogen bomb.

    Because there was no telling how heavy the warhead would be, its R-7 ballistic missile was built with thrust to spare — "much more powerful than anything the Americans had," Georgy Grechko, a rocket engineer and cosmonaut, told AP.

    The towering R-7's high thrust and payload capacity, unmatched at the time, just happened to make it the perfect vehicle to launch an object into orbit — something never done before.

    Without the looming nuclear threat, Russian scientists say, Sputnik would probably have gotten off the ground much later.

    "The key reason behind the emergence of Sputnik was the Cold War atmosphere and our race against the Americans," Chertok said. "The military missile was the main thing we were thinking of at the moment."

    When the warhead project hit a snag, Korolyov, the father of the Soviet space program, seized the opportunity.

    Korolyov, both visionary scientist and iron-willed manager, pressed the Kremlin to let him launch a satellite. The U.S. was already planning such a move in 1958, he pointed out, as part of the International Geophysical Year.

    But while the government gave approval in January 1956, the military brass wanted to keep the missile for the bomb program, Grechko, 76, said in an interview. "They treated the satellite as a toy, a silly fantasy of Korolyov."

    The U.S. had its own satellite program, Grechko said. "The Americans proudly called their project 'Vanguard,' but found themselves behind us."

    The Soviet Union already had a full-fledged scientific satellite in development, but it would take too long to complete, Korolyov knew. So he ordered his team to quickly sketch a primitive orbiter. It was called PS-1, for "Prosteishiy Sputnik" — the Simplest Satellite.

    Grechko, who calculated the trajectory for the first satellite's launch, said he and other young engineers tried to persuade Korolyov to pack Sputnik with some scientific instruments. Korolyov refused, saying there was no time.

    "If Korolyov had listened to us and started putting more equipment on board, the Americans could have opened the space era," Grechko said.

    The satellite, weighing just 184 pounds, was built in less than three months. Soviet designers built a pressurized sphere of polished aluminum alloy with two radio transmitters and four antennas. An earlier satellite project envisaged a cone shape, but Korolyov preferred the sphere.

    "The Earth is a sphere, and its first satellite also must have a spherical shape," Chertok, a longtime deputy of Korolyov, recalled him saying.

    Sputnik's surface was polished to perfection to better deflect the sun's rays and avoid overheating.

    The launch was first scheduled for Oct. 6. But Korolyov suspected that the U.S. might be planning a launch a day earlier. The KGB was asked to check, and reported turning up nothing.

    Korolyov was taking no chances. He immediately canceled some last-minute tests and moved up the launch by two days, to Oct. 4, 1957.

    "Better than anyone else Korolyov understood how important it was to open the space era," Grechko said. "The Earth had just one moon for a billion years and suddenly it would have another, artificial moon!"

    Soon after blastoff from the arid steppes of the Soviet Republic of Kazakhstan, the satellite sent out what would be the world's most famous beep. But the engineers on the ground didn't immediately grasp its importance.

    "At that moment we couldn't fully understand what we had done," Chertok recalled. "We felt ecstatic about it only later, when the entire world ran amok. Only four or five days later did we realize that it was a turning point in the history of civilization."

    Immediately after the launch, Korolyov called Soviet leader Nikita Khrushchev to report the success. Khrushchev's son, Sergei, who was alongside his father at the moment, recalled that they listened to the satellite's beep-beep and went to bed.

    Sergei Khrushchev said that at first they saw the Sputnik's launch as simply one in a series of Soviet technological achievements, like a new passenger jet or the first atomic power plant.

    "All of us — Korolyov's men, people in the government, Khrushchev and myself — saw that as just yet another accomplishment showing that the Soviet economy and science were on the right track," the younger Khrushchev, now a senior fellow at Brown University's Watson Institute for International Studies, said in a telephone interview.

    The first official Soviet report of Sputnik's launch was brief and buried deep in Pravda, the Communist Party daily. Only two days later did it offer a banner headline, quoting the avalanche of foreign praise.

    Pravda also published a description of Sputnik's orbit to help people watch it pass. The article failed to mention that the light seen moving across the sky was the spent booster rocket's second stage, which was in roughly same orbit, Chertok said.

    The tiny orbiter was invisible to the naked eye.

    Excited by the global furor, Khrushchev ordered Korolyov immediately to launch a new satellite, this time, to mark the Nov. 7 anniversary of the 1917 Bolshevik Revolution.

    "We didn't believe that you would outpace the Americans with your satellite, but you did it. Now you should launch something new by Nov. 7," Korolyov quoted Khrushchev telling him, according to Grechko.

    Working round-the-clock, Korolyov and his team built another spacecraft in less than a month. On Nov. 3, they launched Sputnik 2, which weighed 1,118 pounds. It carried the world's first living payload, a mongrel dog named Laika, in its tiny pressurized cabin.

    The dog died of the heat after a week, drawing protests from animal-lovers. But the flight proved that a living being could survive in space, paving the way for human flight.

    The first Sputnik beeped for three weeks and spent about three months in orbit before burning up in the atmosphere. It circled Earth more than 1,400 times, at just under 100 minutes an orbit.

    For Korolyov there was bitterness as well as triumph. He was never mentioned in any contemporary accounts of the launch, and his key role was known to only a few officials and space designers.

    Leonid Sedov, a member of the Soviet Academy of Sciences with no connection to space program, was erroneously touted in the West as the Father of Sputnik. Korolyov, meanwhile, was only allowed to publish his non-sensitive research under the pseudonym "Professor K. Sergeyev."

    Khrushchev rejected the Nobel committee's offer to nominate Korolyov for a prize, insisting that it was the achievement of "the entire Soviet people."

    Sergei Khrushchev said his father thought singling out Korolyov would anger other rocket designers and hamper the missile and space programs.

    "These people were like actors; they would all have been madly jealous at Korolyov," he said. "I think my father's decision was psychologically correct. But, of course, Sergei Korolyov felt deeply hurt."

    Korolyov's daughter, Natalia, recalled in a book that the veil of secrecy vexed her father. "We are like miners — we work underground," she recalls him saying. "No one sees or hears us."

    The Soviet Union and the rest of the world learned Korolyov's name only after his death in 1966. Today his Moscow home, where Chertok met reporters, is a museum in the chief scientist's honor.

    Chertok was permitted to travel abroad only in the late 1980s, after Soviet leader Mikhail Gorbachev liberalized the Soviet Union.

    The surviving leaders of the space program are no longer anonymous or silent, and revel in the accolades so long denied them.

    "The rivalry in space, even though it had military reasons, has pushed the mankind forward," said Valery Korzun, a cosmonaut who serves as a deputy chief of the Star City cosmonaut training center. "Our achievements today are rooted in that competition."

    In the end, it was the Americans who won the race to the moon, nearly 22 years later. Khrushchev wasn't interested in getting there, his son says, and the effort made under his successor, Leonid Brezhnev, was underfunded and badly hampered by rifts between Korolyov and other designers.

    "We wouldn't have been the first on the moon anyway," Grechko said. "We lost the race because our electronics industry was inferior."

    Today, even as Sputnik recedes into the history books, its memory still exercises a powerful grip. In August, when a Russian flag was planted on the sea bed at the North Pole, the Kremlin compared it to Neil Armstrong stepping on the moon — an indication, perhaps, of how much Russians still treasure that first victory in space.

    Re: 50 Years of Space Exploration

    a ticket for sale.......

    Fly me to the moon? That’ll be $100 million

    The company that pioneered commercial space travel by sending “tourists” up to the International Space Station is planning a new mission: rocketing people around the far side of the moon.

    The price of a round-trip ticket: $100 million.

    The first mission by Space Adventures could happen in 2008 or 2009 and is planned as a stepping stone to an eventual lunar landing by private citizens.

    The trip, aboard a modified Russian spacecraft, will offer the chance to see the Earth rise from lunar orbit and a view of the far side of the moon from an altitude of 62 miles.

    The far side of the moon has a special appeal, because it takes most of the hits from asteroids, meteorites and other objects from deep space. That results in many more craters than on the side seen from Earth.

    “It’s much more interesting to look at than the near side,” he said, adding that the lunar orbits will be done when the far side is illuminated by the sun.

    Space Adventures plans to offer multiple trip itineraries aboard Russia’s Soyuz TMA spacecraft. One possibility is a 5½-day lunar flight and up to 21 days at the ISS; another is a nine-day mission with three days of free flight in low-Earth orbit and the rest flying around the moon. In both cases, the spacecraft would dock with a booster, carried up by a separate launch vehicle, to propel it to the moon.

    The Soyuz was originally designed for lunar missions, although none ever occurred.

    It has 10 cubic meters of crew space, about the size of a large SUV. The cosmonaut and two passengers will sleep in reclining chairs, said Nikolai Sevastyanov, president of rocket maker Rocket and Space Corporation Energia.

    Space Adventures has a partnership with the rocket maker and the Federal Space Agency of the Russian Federation, through which they have sent American businessman Dennis Tito and South African Mark Shuttleworth on a Soyuz for stays on the space station.

    The next mission is slated to send a team up to the space station for 10 days starting Oct. 1. One of the crew members is Gregory Olsen, a New Jersey scientist who has been training for the mission in Russia on and off since 2004.

    “Who wouldn’t want to go to the moon?” said Olsen, 60, a surprise guest at the news conference. “I’m really interested, but one flight at a time.”

    Modifications to the Soyuz will include altering its docking system and installing an 18-inch window so passengers can take high-resolution photos of the lunar surface.

    Re: 50 Years of Space Exploration

    MOSCOW - Goose-stepping guards and medal-bedecked space veterans laid flowers at the Kremlin wall tomb of the father of the Soviet space program Thursday as Russia celebrated the 50th anniversary of the launch of Sputnik, the world’s first artificial satellite.

    The name of Sergei Korolyov, the visionary rocket scientist whose brains and determination made it possible for the Soviet Union to thrust open the door to the space age, was a top state secret during his lifetime. It became known only became known after he died and was given a lavish state funeral.

    “We take a rightful pride in the fact that it was our nation which opened the way to the stars for humanity,” President Vladimir Putin said in a statement.

    Image: Sputnik anniversary

     

    Ceremonies were held at the Russia’s cosmonaut training center, Star City, outside Moscow, and engineers gathered at the Academy of Sciences to recall the events leading up to the Oct. 4, 1957, launch of the 184-pound (84-kilogram) metal ball with the spiked antennas that beeped as it orbited the Earth.

    Engineers who worked on Sputnik’s launch recalled that they did not immediately fathom the impact of their achievement.

    Its launch “sparked an unexpected furor around the world. No one expected this, even including our engineers,” Viktor Frusmon, a co-worker of Korolyov’s, said in a televised comments.

    Stunning the world
    The success of Soviet engineers stunned the world, and the launch was followed just four years later by another historic achievement — the voyage of Yuri Gagarin, the first human in space.

    Sputnik galvanized the United States to pour money into space research and technology with the goal of landing a man on the moon — an event that occurred in 1969.

    “The Sputnik accomplishment by the Russian people was responsible for the creation of the American space program,” said NASA Administrator Michael Griffin, who hailed Russia’s space achievements in a speech before space veterans and scientists.

    getCSS("3053751")
    After decades of rivalry, Russia and the United States have developed a close cooperation in space. Russian spacecraft now ferry crews and cargo to the international space station, and the two nations also cooperate on other missions.

    On Wednesday, Griffin and Russian Space Agency chief Anatoly Perminov signed an agreement to put Russian scientific instruments on board U.S. probes that would be sent to the moon and Mars to search for potential water deposits.

    “We have much learned from each other, and I think we can go father together than either of us can go separately,” Griffin said.

    In recent years, the Kremlin has used some of Russia’s booming oil revenues to revive space program, which had experienced a severe funding shortage amid the post-Soviet economic turmoil.
