Endeavour - From the American Soil Back to Space!


History was made on May 30, 2020, when NASA and SpaceX successfully launched two American astronauts, Bob Behnken and Doug Hurley, to Space in a Dragon capsule named Endeavour.

This first manned mission from the American soil in almost forty years ends NASA's dependence on foreign launch providers to send their astronauts to the International Space Station.

On May 31, the Endeavour successfully docked on to the ISS. The two astronauts were cordially welcomed by the ISS crew. They will remain in the Space for 110 days before returning back to Earth.

The launch and the docking maneuver were transmitted live on social media and broadcast on television networks all over the world. At least ten million people watched this historical event.

One Small Step For A Man...


"Here men from the planet Earth first set foot upon the moon. 
July 1969 A.D. We came in peace for all mankind." - 
text from a commemorative plaque on one of the Eagle's legs.

Fifty years ago, at 10: 56 EDT on July 20, 1969, Neil Armstrong was ready to step out of the "Eagle" and become the first human being in history to set his foot on the surface of the Moon. 

More than half a billion people all over the world were watching the first televised images. As Armstrong climbed down the ladder, the viewers could hear him say his famous words: 

"That's one small step for a man, one giant leap for mankind."

A few minutes later, Buzz Aldrin joined Armstrong on the Moon surface. For Aldrin the Moon was a "magnificent desolation." 

The two astronauts planted an American flag and spent the next two and a half hours exploring the surface of the Moon, collecting rock samples, and taking photographs. 

The mission was a success. It ended when the Columbia capsule carrying the astronauts splashed into the ocean off the coast of Hawaii on July 24, 1969. 

A new era has begun. New missions to the Moon followed over the next three and a half years. Some people, most notably Wernher von Braun, Vice President Spiro Agnew, and the Apollo 11 astronaut Mike Collins, were talking about mission to Mars that could be accomplished before the end of the 20th century. Kids like me hoped that by the year 2000 we would be spending our summer vacations on the Moon. In 1973 NASA abandoned its lunar program and all our dreams became science fiction once again.

50th Anniversary of the Apollo 11 Lift Off


Fifty years ago on July 16, 1969, an incredible human adventure has begun: Apollo 11 was launched by a Saturn V rocket at 9:32 ET (13:32 UTC) from Cape Kennedy (formerly Cape Canaveral,) Florida, and headed for the Moon.

The spacecraft carried three American astronauts - Commander Neil Armstrong, Command Module Pilot Michael Collins and Lunar Module Pilot Edwin "Buzz" Aldrin. It consisted of three parts: a Command Module with the cabin for the three astronauts; a Service Module designed to support the Command Module with propulsion, electrical power, oxygen, and water; and a Lunar Module "Eagle" that had two stages - the descent stage for the landing on the Moon's surface, and the ascent stage for the transport of the astronauts back into the lunar orbit.

Almost a million people descended on Cape Kennedy to watch the lift off of Apollo 11. Millions of people all over the world watched the lift off and followed the progress of the mission on television. It would take another four days for the spacecraft to reach its destination.

The mission to the Moon was initiated on May 25, 1961, when President John F. Kennedy issued his famous challenge to Congress and the American people: “I believe that this Nation should commit itself to achieving the goal, before this decade is out, of landing a man on the Moon and returning him safely to Earth.”

Incredible 410,000 people were involved in the mission's success, many nameless, but many well known and remembered to this day. The Saturn V rocket itself was a pet project of a German aerospace engineer, former SS Wernher von Braun, who was involved in  the construction of the V2 rocket in Peenemünde during the WWII. The American space program included a few more Germans with a Nazi past, some of them war criminals like Arthur Rudolph who also worked on the V2; and  Hubertus Strughold who conducted various medical experiments on inmates from the concentration camp in Dachau.

These "details" cast a very dark shadow over the American space program. They were not revealed to the American public at that time. In the middle of Cold War, NASA simply wanted to succeed in the space race against the Soviets and this would not have been possible without the knowledge and expertise of the German scientists. History was made. The mission was a success. This was all that mattered.

By Dominique Teng

*Hitler's secret V2 project at Peenemünde was an incredible advancement in war technology with grim statistics. In 1944 more than 1,300 rockets were fired at England, Belgium and France killing 2,724 people in Britain alone. Estimated 20,000 slave workers lost their lives in harsh working conditions at the facilities at Peenemünde and Mittelwerk manufacturing the deadly weapon.

Legendary American Astronaut John Glenn Dead at 95

Legendary American Astronaut John Glenn Dead at 95
John Herschel Glenn Jr. (July 18, 1921 – December 8, 2016)

John H. Glenn Jr, the first American to orbit the Earth passed away in Columbus, Ohio on December 8, 2016 at the age 95. America has lost one of its greatest pioneers.

Glenn was an aviator, engineer at NASA, astronaut, politician, and recipient of the Congressional Space Medal of Honor. He was an officer in the US Marine Corps and a war hero who served his country as a fighter pilot in the Pacific during WWII and during the Korean War. 

In 1962 he became the first American to orbit the Earth. he flew the Friendship 7 mission and was also a backup pilot to Alan Shepard and Gus Grissom, on the Freedom 7 and Liberty Bell 7 respectively.

In 1974 he won elections for the US Senate and became a congressman representing the State of Ohio for a quarter of a century.

A legend and a true here, he will be missed by many.

Godspeed, John Glenn!

Entering Space


Today the human race is a single twig on the tree of life, a single species on a single planet. Our condition can thus only be described as extremely fragile, endangered by forces of nature currently beyond our control, our own mistakes, and other branches of the wildly blossoming tree itself. Looked at this way, we can then pose the question of the future of humanity on Earth, in the solar system, and in the galaxy from the standpoint of both evolutionary biology and human nature. The conclusion is straightforward: Our choice is to grow, branch, spread and develop, or stagnate and die. - Robert Zubrin, Entering Space, 1999

In time, a Martian colony would grow to the point of being self- sustaining. When this stage was reached, humanity would have a precious insurance policy against catastrophe at home. During the next millennium there is a significant chance that civilization on Earth will be destroyed by an asteroid, a killer plague or a global war. A Martian colony could keep the flame of civilization and culture alive until Earth could be reverse- colonized from Mars. - Paul Davies, The New York Times, 2004

128,000 ft Jump!

Everyone has limits. Not every one accepts them. - Felix Baumgartner

Everyone has limits. Not every one accepts them. - Felix Baumgartner

Austrian extreme athlete Felix Baumgartner, aka Fearless Felix, jumped from the altitude of 128,097 feet around noon this Sunday, October 14, just outside of Roswell, NM, breaking several world records: highest free-fall, fastest free-fall, and highest manned balloon flight.

The free-fall lasted 4 minutes 22 seconds.

Although Baumgartner broke several world records today, he was unable to break Kittinger's free-fall record.

The Red Bull Stratos mission to the Edge of Space attempted to transcend human limits that had been set by Joseph W. Kittinger some 50 years ago. 

The Red Bull Stratos team brought together the world's leading minds in aerospace medicine, engineering, pressure suit development, capsule creation and balloon fabrication. It included retired United States Air Force Colonel Joseph Kittinger, who holds three of the records Felix wanted to break.

Joe's record jump from 102,800 ft in 1960 was during a time when no one knew if a human could survive a jump from the edge of space. Joe was a Captain in the U.S. Air Force and had already taken a balloon to 97,000 feet in Project ManHigh and survived a drogue mishap during a jump from 76,400 feet in Excelsior I. The Excelsior III mission was his 33rd parachute jump. This was the time he established a world record that remains unbroken to this day. Kittinger's free-fall lasted 4 minutes 36 seconds - 14 seconds longer than Baumgartner's. 

 Felix Baumgartner in free-fall

Although researching extremes was part of the program's goals, setting records wasn't the mission's purpose. Joe ascended in helium balloon launched from the back of a truck. He wore a pressurized suit on the way up in an open, unpressurized gondola. Scientific data captured from Joe's jump was shared with U.S. research personnel for development of the space program. Today Felix and his specialized team hoped to take what was learned from Joe's jumps more than 50 years ago and press forward to test the limits of the human capacity.
 
Landed safely east of Roswell
 
Baumgartenr ascended to the low stratosphere in a capsule that was carried by a balloon which itself was a technological marvel.

The balloon was constructed of strips of high-performance polyethylene (plastic) film that was only 0.0008 inches thick or 10 times thinner than a lunch bag. In total, these strips would cover 40 acres if they were laid flat. Polyester-fibre reinforced load tapes were incorporated to do the weight bearing.

The Stratos balloon was filled with 30 million cubic feet of helium which10 times larger than Joe Kittinger's balloon in 1960.

The Roswell-jump not only terminated Baumgartner's skydiving career, but it also marked the 65th anniversary of US test pilot Chuck Yeager successful attempt to become the first man ever to officially break the sound barrier aboard an airplane.

Global Consciousness


You develop an instant global consciousness, a people orientation, an intense dissatisfaction with the state of the world, and a compulsion to do something about it. From out there on the moon, international politics look so petty. You want to grab a politician by the scruff of the neck and drag him a quarter of a million miles out and say, ‘Look at that, you son of a bitch. -  Apollo 14 astronaut Edgar Mitchell

Neil Armstrong, the first human ever to walk on the surface of the moon, died Saturday, August 25, at age 82.

Armstrong was catapulted onto the world stage on July 20, 1969, when, as commander of NASA's Apollo 11 mission, he stepped on to the moon's surface for the first time and said words that will forever be remembered: "That is one small step for (a) man, one giant leap for mankind."

Armstrong died due to complications from recent heart surgery. He was a Navy test pilot before joining NASA's astronaut corps in 1962 and was one of a handful of pilots to fly the X-15 rocket.

"We will never forget that one small step you took so the rest of us could take a giant leap toward the stars."

Curiosity on Mars

 Mars Rover Curiosity

A week ago on August 5, NASA successfully landed its most advanced rover Curiosity on Mars. This landing marks another giant step in space exploration.

The one-ton rover, hanging by ropes from a rocket backpack, touched down onto Mars surface last Sunday to end a 36-week long flight and begin its two-year surface investigation.

The Mars Science Laboratory (MSL) spacecraft that carried Curiosity succeeded in every step of the most complex landing ever attempted on Mars, including the final severing of the bridle cords and flyaway maneuver of the rocket backpack.

"Today, the wheels of Curiosity have begun to blaze the trail for human footprints on Mars. Curiosity, the most sophisticated rover ever built, is now on the surface of the Red Planet, where it will seek to answer age-old questions about whether life ever existed on Mars - or if the planet can sustain life in the future," said NASA Administrator Charles Bolden. "This is an amazing achievement, made possible by a team of scientists and engineers from around the world and led by the extraordinary men and women of NASA and our Jet Propulsion Laboratory. President Obama has laid out a bold vision for sending humans to Mars in the mid-2030's, and today's landing marks a significant step toward achieving this goal."

Curiosity landed near the foot of a mountain three miles tall and 96 miles in diameter inside Gale Crater. During a nearly two-year prime mission, the rover will investigate whether the region ever offered conditions favorable for microbial life.

Successful landing

"The Seven Minutes of Terror has turned into the Seven Minutes of Triumph," said NASA Associate Administrator for Science John Grunsfeld. "My immense joy in the success of this mission is matched only by overwhelming pride I feel for the women and men of the mission's team."

Curiosity returned its first view of Mars, a wide-angle scene of rocky ground near the front of the rover. More images are anticipated in the next several days as the mission blends observations of the landing site with activities to configure the rover for work and check the performance of its instruments and mechanisms.

Curiosity carries 10 science instruments with a total mass 15 times as large as the science payloads on the Mars rovers Spirit and Opportunity. Some of the tools are the first of their kind on Mars, such as a laser-firing instrument for checking elemental composition of rocks from a distance. The rover will use a drill and scoop at the end of its robotic arm to gather soil and powdered samples of rock interiors, then sieve and parcel out these samples into analytical laboratory instruments inside the rover.

To handle this science toolkit, Curiosity is twice as long and five times as heavy as the other Mars rovers - the Spirit and the Opportunity. 

The Gale Crater landing site places the rover within driving distance of layers of the crater's interior mountain. Observations from orbit have identified clay and sulfate minerals in the lower layers, indicating a wet history. 

High resolution image from Mars

To satisfy our and NASA's curiosity, the rover began sending images from Mars. The images from Curiosity's just-activated navigation cameras, or Navcams, include the rover's first self-portrait, looking down at its deck from above. Another Navcam image set, in lower-resolution thumbnails, is the first 360-degree view of Curiosity's new home in Gale Crater. We also had a chance to admire a higher-resolution images providing the most detailed depiction to date of the surface adjacent to the rover.

Meanwhile, a healthy Curiosity spent Sol 4, its fifth day on Mars, preparing for this weekend's planned "brain transplant" - a transitioning to a new version of flight software on both of its redundant main computers. The new software is better suited for Mars surface operations, such as driving and using Curiosity's robotic arm. 


Image from Mars - Mount Sharp

The "brain transplant" will take place during a series of steps beginning this evening and continuing through Aug. 13. The new software was uploaded to the rover's memory during the Mars Science Laboratory spacecraft's flight from Earth. Key capabilities in the new software enable full use of Curiosity's powerful robotic arm and drill, and advanced image processing to check for obstacles while driving. This will ultimately allow Curiosity to make longer drives by giving the rover more autonomy to identify and avoid potential hazards and to drive along a safe path that the rover identifies for itself.

Most of us will probably forget about this mission by the end of the Summer, but for countless scientists Curiosity opens new horizons. The data coming from Mars will help them in their next endeavor - a manned Mission to Mars.

Space - The Missing Frontier

The last frontier?
Stellar cluster NGC 2467 in southern constellation of Puppis

By Douglas Mackinnon

As most of us who have worked in and around politics for any length of time know, if a certain issue is not an immediate vote-getter or “tangible” for a politician, there is a better than even chance that the issue will be ignored or deposited upon the furthest back-burner.

For many of our elected officials, everyday political calculation comes down to this: “What’s best for my re-election and what’s best for my party?” In that order. With fewer and fewer people in power whose first thought is: “What’s the best decision I can make that will be in the best interests of my constituents?” It’s no wonder that more young people are giving up on politics while their elders abandon the political parties to become Independents.

While the if-it’s-not-tangible-and-I-can’t-game-it-immediately-to-my-benefit test may be great for a politician, it’s often very bad for the country. “Tangible” being political slang for “that federal office building will now be located in my district.”

As for the “non-tangible,” a great example would be our space program. Or to be more accurate, our non-space program. It has never really been relevant for most of our politicians or presidents. The truth is that only one president really thought that space exploration was a tangible national vote-getter.

Whatever his real motivation, on Sept.12, 1962 at Rice University, John F. Kennedy stated in no uncertain terms that in the interests of science, industry and national security, the United States would become the “world’s leading spacefaring nation.” And so we did – for nearly five decades.

Today, that preeminence is nothing more than a fading memory. While President Obama - who as a candidate made it very clear that he valued education over space exploration - may have pushed our human spaceflight program over the cliff, other presidents led it to the edge.

With Florida a key battleground state in the presidential election, the White House and the political appointees at NASA will argue furiously that the president has not walked away from our human space program. They will point to his plans to land astronauts on the asteroids one day. Right. That goal, exactly like George H.W. Bush’s plan in 1989 to send astronauts to Mars, is simply fiction.

I worked in politics for a long time, but I began life as a space geek. I started a scrapbook on the Soviet space program when I was 10 and decades later got to write a book about the 12 men who have walked on the moon. After my time in government, I worked as a consultant for NASA and the Space Shuttle team. In other words, I admit that I have always been a fan of humans in space. Any humans in space.

That said, the humans who are now winning the space race come from the People’s Republic of China. It is clear from their own propaganda that China means to replace us as the “world’s leading spacefaring nation.”

It has been argued in the past that while the United States and other Western nations see the future in terms of months or years, the Chinese see it in terms of decades or even centuries. With that perspective in mind, the Chinese government intends to win not the space race, but the space marathon. They intend to take military, industrial and scientific advantage there.

After the just completed launch and recovery of China’s first female astronaut - Liu Yang, who with two male astronauts, was part of a very successful 13 day mission to dock with a Chinese space station - many in the media covered it as a human-interest story or even a politically correct equal-rights story. Nice, but the completely wrong way to view the Chinese achievement.

Naïve and irresponsible beliefs aside, China’s space program is essentially military. Its every function is designed to carry out a military objective or one that improves the welfare of the state. Nothing else matters to the Chinese leadership.

Toward that end, the Chinese government has been investing a great deal of time and talent in a wide range of anti-satellite weapons and technologies. Aside from direct ascent kinetic kill vehicles (like the one it tested in 2007), the Chinese military space program is also working on laser, jamming, microwave and cyber-weapons.

Why?  Because the Chinese leadership - the same leadership that has made hacking our military and commercial computers a priority - understands that no nation on earth is more dependent for its overall survival on its satellites than the United States. Satellites control our military communications, our financial transactions and our day-to-day lives. What if they went dark or were destroyed in orbit?

The Chinese leaders - and others - would certainly say that a military advantage in space is “tangible” and a goal worth attaining. But preeminence is space is about much more than military advantage.  Neil deGrasse Tyson, the director of the Hayden Planetarium at the American Museum of Natural History in New York, outlined that argument when he told Popular Science earlier this year:
If China sets up a permanent base on the moon, and tries to explore Mars on a time scale shorter than ours, that will be another space race. I am just certain of it. I am trying to get people to do this without having to view it as an act of war, or an act of a response to an adversary. One way is because of economics; the government could do this, and they could say, “The economic return is the scientists and technologists who invent the new tomorrow.” Space exploration is the carrot that incites people to become scientifically literate. So I view it as an economic development plan.
Maybe it’s time for the president and his Republican opponent to elevate a few issues to the “tangible” list regardless of personal or partisan self-interest. As China launches military satellite after military satellite while declaring its intention to colonize the moon, maybe preeminence in space should be one of them.

During the transition period after he defeated John McCain, Obama contemplated combining the best of the space programs at the Pentagon and NASA to compete with the rapidly accelerating Chinese space program. For whatever reasons, he declined to follow through on that plan when he became president.

The president should dust off those plans. Given the fact that during the height of the war in Iraq, our government was spending nearly a billion dollars a day, I suspect the American people would support spending a month’s worth of that budget every year to ensure that our assets in space and our future on earth are more secure. But to support it, they first need to be convinced of its importance. So do our leaders.

Much Ado About Nothing


By Michael Shermer

Why is there something rather that nothing? This is one of those profound questions that is easy to ask but difficult to answer. For millennia humans simply said, “God did it”: a creator existed before the universe and brought it into existence out of nothing. But this just begs the question of what created God - and if God does not need a creator, logic dictates that neither does the universe. Science deals with natural (not supernatural) causes and, as such, has several ways of exploring where the “something” came from.

Multiple universes. There are many multiverse hypotheses predicted from mathematics and physics that show how our universe may have been born from another universe. For example, our universe may be just one of many bubble universes with varying laws of nature. Those universes with laws similar to ours will produce stars, some of which collapse into black holes and singularities that give birth to new universes - in a manner similar to the singularity that physicists believe gave rise to the big bang.

M-theory. In his and Leonard Mlodinow’s 2010 book, The Grand Design, Stephen Hawking embraces “M-theory” (an extension of string theory that includes 11 dimensions) as “the only candidate for a complete theory of the universe. If it is finite - and this has yet to be proved - it will be a model of a universe that creates itself.”   

Quantum foam creation. The “nothing” of the vacuum of space actually consists of subatomic spacetime turbulence at extremely small distances measurable at the Planck scale - the length at which the structure of spacetime is dominated by quantum gravity. At this scale, the Heisenberg uncertainty principle allows energy to briefly decay into particles and antiparticles, thereby producing “something” from “nothing.” 

Nothing is unstable. In his new book, A Universe from Nothing, cosmologist Lawrence M. Krauss attempts to link quantum physics to Einstein’s general theory of relativity to explain the origin of a universe from nothing: “In quantum gravity, universes can, and indeed always will, spontaneously appear from nothing. Such universes need not be empty, but can have matter and radiation in them, as long as the total energy, including the negative energy associated with gravity [balancing the positive energy of matter], is zero.” Furthermore, “for the closed universes that might be created through such mechanisms to last for longer than infinitesimal times, something like inflation is necessary.” 

Observations show that the universe is in fact flat (there is just enough matter to slow its expansion but not to halt it), has zero total energy and underwent rapid inflation, or expansion, soon after the big bang, as described by inflationary cosmology. Krauss concludes: “Quantum gravity not only appears to allow universes to be created from nothing - meaning absence of space and time - it may require them. ‘Nothing’ - in this case no space, no time, no anything! - is unstable.” 

The other hypotheses are also testable. The idea that new universes can emerge from collapsing black holes may be illuminated through additional knowledge about the properties of black holes, which are being studied now. Other bubble universes might be detected in the subtle temperature variations of the cosmic microwave background radiation left over from the big bang of our own universe. NASA’s Wilkinson Microwave Anisotropy Probe (WMAP) spacecraft is collecting data on this radiation. Additionally, the Laser Interferometer Gravitational Wave Observatory (LIGO) is designed to detect exceptionally faint gravitational waves. If there are other universes, perhaps ripples in gravitational waves will signal their presence. Maybe gravity is such a relatively weak force (compared with electromagnetism and the nuclear forces) because some of it “leaks” out to other universes. 

Even if God is hypothesized as the creator of the laws of nature that caused the universe (or multiverse) to pop into existence out of nothing - if such laws are deterministic - then God had no choice in the creation of the universe and thus was not needed. In any case, why turn to the supernatural when our understanding of the natural is still in its incipient stages? We would be wise to heed this skeptical principle: before you say something is out of this world, first make sure that it is not in this world.

SpaceX Makes History! Dragon in Space!

Falcon 9 over Florida
Falcon 9 over Florida
“Never doubt that a small group of committed people can change the world. In fact, it is the only thing that ever has.” - Margaret Mead
A privately owned company made history today! The California-based Space Exploration Technologies SpaceX successfully launched its unmanned Dragon capsule into orbit at 3.44 this morning, May 22,  from the Cape Canaveral Air Force Station in Florida.

The Dragon was carried by the Falcon 9 rocket and reached the orbit 9 minutes after lift off. Its mission is the International Space Station. The craft is programmed to perform a number of maneuvers which include docking with the ISS.

After successful docking the astronauts will be able to access the Dragon which carries supplies for the ISS.

Every launch into space is exciting, but success of a privately owned company after decades of NASA is really something special. The future belongs to the visionaries!

First Man on the Moon

Neil Armstrong on the surface of the Moon, July 20, 1969
 Neil Armstrong on the surface of the Moon, July 20, 1969

Forty two years ago, on July 20, 1969, Neil Armstrong became the first human to step on the surface of the Moon. This historic moment was viewed by millions of people all over the world. 

Everything began in 1961 when John F. Kennedy was the president of the United States. He wanted to land humans on the Moon. But was NASA ready to go to the Moon? The president and NASA knew they could do it. 

Apollo 11 blasted off on July 16, 1969. Neil Armstrong, Edwin "Buzz" Aldrin and Michael Collins were the astronauts on Apollo 11. Four days later, on July 20, Armstrong and Aldrin landed on the moon. They landed on the moon in the Lunar Module. It was called the Eagle. Collins stayed in the orbit around the moon. He did experiments and took photographs.

Armstrong and Aldrin walked on the surface of the Moon for three hours. They performed various experiments  and took samples of the moon dirt and some rocks. They left an American flag on the Moon and a sign that read "Here men from the planet Earth first set foot upon the moon July 1969, A.D. We came in peace for all mankind."

The two astronauts returned to orbit, joining Collins. On July 24, 1969, all three astronauts landed safely on Earth.

Atlantis - The Final Flight of the Space Shuttle Program

Space shuttle Atlantis at the launch pad 39A.
Kennedy Space Center, Cape Canaveral - July 7, 2011.

Space shuttle Atlantis is scheduled to liftoff today, July 8 on its final flight, STS-135, a 12-day mission to the International Space Station. The liftoff will mark the end of the 30-year old space shuttle program.

Atlantis will carry a crew of four and the Raffaello multipurpose logistics module containing supplies and spare parts for the space station. The STS-135 astronauts are: Commander Chris Ferguson, Pilot Doug Hurley, and Mission Specialists Sandy Magnus and Rex Walheim. 

The final U.S. space shuttle flight may, however, be postponed due to thunderstorms, but according to NASA officials the countdown was still under way hours before the scheduled launch.

We wish the entire team best of luck for this historic mission. And of course, good weather for the liftoff!

Valentina Tereschkova - First Woman in Space


Colonel-Engineer Valentina Vladimirovna Tereshkova (born March 6, 1937) was a Soviet cosmonaut and the first woman in Space. She was on the Vostok 6 mission which launched on June 16, 1963, and orbited the Earth 48 times. The flight lasted 70.8 hours.

The Vostok 5 spacecraft was recovered on June 19, 1963, in the Soviet Union. Tereshkova had parachuted from the spacecraft after earth's atmospheric re-entry. She landed about 380 miles northeast of Karaganda, Kazakhstan. 

Tereshkova had been an expert in parachuting and a factory worker before she wrote to the Soviet Space program, volunteering to become the first woman in Space. She was selected out of more than 400 applicants and was subjected to extensive tests and interviews that began in December 1961. 

Two women, Valentina Tereshkova and Tatyana Torchillova were chosen in May 1963, to train for the Vostok 6 flight. Tereshkova, however, was the final choice. 

Tereshkova was given the title "Hero of the Soviet Union," received the Order of Lenin, and was honored with the United Nations Gold Medal of Peace. She never flew into Space again.

Race in Space

President John F. Kennedy speaking before Congress in May 25, 1961
 President John F. Kennedy speaking before Congress in May 25, 1961
If we are to win the battle that is now going on around the world between freedom and tyranny, the dramatic achievements in space which occurred in recent weeks should have made clear to us all, as did the Sputnik in 1957, the impact of this adventure on the minds of men everywhere, who are attempting to make a determination of which road they should take. Since early in my term, our efforts in space have been under review. With the advice of the Vice President, who is Chairman of the National Space Council, we have examined where we are strong and where we are not, where we may succeed and where we may not. Now it is time to take longer strides - time for a great new American enterprise - time for this nation to take a clearly leading role in space achievement, which in many ways may hold the key to our future on earth. (...) I believe that this nation should commit itself to achieving the goal, before this decade is out, of landing a man on the moon and returning him safely to the earth. - John F. Kennedy
On May 25, 1961, President John F. Kennedy announced before a special joint session of Congress the dramatic and ambitious goal of sending an American safely to the Moon before the end of the decade.

A number of political factors affected Kennedy's decision and the timing of it. In general, Kennedy felt great pressure to have the United States "catch up to and overtake" the Soviet Union in the "space race." 

Four years after the Sputnik shock of 1957, the cosmonaut Yuri Gagarin had become the first human in space on April 12, 1961, greatly embarrassing the U.S. While Alan Shepard became the first American in space on May 5, he only flew on a short suborbital flight instead of orbiting the Earth, as Gagarin had done. In addition, the Bay of Pigs fiasco in mid-April put unquantifiable pressure on Kennedy. He wanted to announce a program that the U.S. had a strong chance at achieving before the Soviet Union. 

After consulting with Vice President Johnson, NASA Administrator James Webb, and other officials, he concluded that landing an American on the Moon would be a very challenging technological feat, but an area of space exploration in which the U.S. actually had a potential lead. 

Thus the cold war is the primary contextual lens through which many historians now view Kennedy's speech. The decision involved much consideration before making it public, as well as enormous human efforts and expenditures to make what became Project Apollo a reality by 1969. Only the construction of the Panama Canal in modern peacetime and the Manhattan Project in war were comparable in scope. 

NASA's overall human spaceflight efforts were guided by Kennedy's speech. Projects Mercury (at least in its latter stages), Gemini, and Apollo were all designed to execute Kennedy's goal. His goal was achieved on July 20, 1969, when Apollo 11 commander Neil Armstrong stepped off the Lunar Module's ladder and onto the Moon's surface.

Successful Launch of Space Shuttle Endeavour!

Endeavour's final liftoff

Space shuttle Endeavour and its crew of six astronauts completed a successful launch today, May 16, 2011, at 8:56 a.m. EDT on a mission to the International Space Station. The mission will last 16 days.

This is the last mission of Endeavour which carries the Alpha Magnetic Spectrometer and a pallet loaded with spare parts to the International Space Station. The AMS is a cutting-edge physics experiment designed to look for anti-matter in the cosmos and perhaps unlock the mystery of what makes up most of the mass in the universe.

Space Shuttle Endeavour Last Flight

After nearly two decades of achievements in space, space shuttle Endeavour was scheduled to make one last reach for the stars on its 25th and final mission. The fourteen day mission would be the 36th shuttle mission to the International Space Station.

The crew members for the shuttle STS-134 mission are Commander Mark Kelly, Pilot Gregory H. Johnson and Mission Specialists Michael Fincke, Greg Chamitoff, Andrew Feustel and European Space Agency astronaut Roberto Vittori.

The mission Commander, Navy Capt. Mark Kelly, is a husband of the wounded Congresswoman Gabrielle Giffords, who will attend the shuttle launch. She has been in Houston, where she is undergoing rehabilitation for a gunshot wound to the head. She was attacked January 8 in her Tucson, Arizona, hometown.

Space shuttle Endeavour has spent nineteen years pushing boundaries, and its final mission will allow that legacy to live on. It was the last shuttle built, and made its maiden flight in May, 1992. After retirement, it will be placed on permanent display at the California Science Center in Los Angeles.

Among Endeavour’s missions was the first to include four spacewalks, and then the first to include five. Its STS-67 mission set a length record almost two full days longer than any shuttle mission before it. Its airlock is the only one to have seen three spacewalkers exit through it for a single spacewalk. And in its cargo bay, the first two pieces of the International Space Station were joined together.

On STS-134, however, it will help push boundaries of a different sort as it delivers a new, cutting edge science experiment to the space station: the Alpha Magnetic Spectrometer.

The Alpha Magnetic Spectrometer is a state-of-the-art, high energy particle physics experiment built in Geneva by a collaboration of 16 different countries. It will search for clues on what the universe is made of and how it began, the origin of dark matter, antimatter and strangelets, pulsars, blazers and gammaray bursters. And that’s just what the scientists know to look for.

After AMS is installed on station’s truss during the fourth day of the mission, a pallet of spare parts will be added to the space station on the mission’s flight day 5. Then there will be a string of spacewalks – the last spacewalks to be performed by a shuttle crew – dedicated to getting the station in the best possible shape for the end of the space shuttle program.

The spacewalkers will top off a leaky ammonia loop and lubricate one of the massive joints that turn the station’s solar array wings. They’ll also add to the Russian segment of the station a handhold for the station’s robotic arm, extending the arm’s range to that area, and make a permanent home on the station’s truss for the shuttle robotic arm’s 50-foot long boom extension, so that it can be left behind to give the station’s arm a greater reach.

The weather forecast calls for a 70 percent chance of favorable conditions at launch time, according to Shuttle Weather Officer Kathy Winters. The only concerns for launch may be the crosswinds at the Shuttle Landing Facility and a low cloud ceiling associated with a front moving into Central Florida.

The final lift off was scheduled for 3:47 p.m. EDT on April 29, 2011 at the NASA Kennedy Space Center's Launch Pad 39A, but due to some technical difficulties it was postponed.

Officials said a delay of at least three days was needed to fix heaters that are being used in the equipment that powers both the movement of both the shuttle’s engines and the flaps during the shuttle's ride into space. The crowd of hundreds of thousands who gathered to witness what was supposed to be the second-to-last takeoff in the space shuttle program - were very disappointed by the delay.

Yuri Gagarin - First Human in Space

Yuri Alekseyevich Gagarin (9 March 1934 - 27 March 1968)

Yuri Alekseyevich Gagarin (9 March 1934 - 27 March 1968) - a Soviet pilot and cosmonaut - was the first human being to travel into outer space. Fifty years ago, on April 12, 1961, the Vostok 1 spacecraft completed the orbit of the Earth. The journey lasted 108 minutes.

Upon his safe return to Earth, Gagarin was celebrated as the greatest man in human history not only in the former Soviet Union, but worldwide and was allowed by the authorities to visit many countries to promote the Soviet achievement in space. Gagarin's flight marked the beginning of a new era in space exploration.
