JFK challenged Americans to take to the skies half a century ago -- but as human space flight embraced rockets rather than reusable spacecraft, what did we lose?
Fifty years ago, on May 25, 1961, President John F. Kennedy stood before Congress and laid out his famous challenge for the nation to "commit itself to achieving the goal, before this decade is out, of landing a man on the moon and returning him safely to earth."
It was a lofty goal that set in motion the intense technology development of the Apollo era, and a moment we remember happily because, after all, we succeeded! Against all odds, Neil Armstrong and Buzz Aldrin set foot on the lunar surface on July 20, 1969, a full five months before the challenge deadline.
Achieving that success took a tremendous investment and focus of money and national resources, of course--an investment that was available because, as Kennedy made clear in his speech, going to the moon was not just an interesting scientific endeavor.
"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 [on May 5, 1961, Alan Shepard had become the first American in space] 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," Kennedy said, stressing that taking a "clearly leading role" in space might even "hold the key to our future on earth."
Why the moon? Because, Kennedy said, "no single space project in this period will be more impressive to mankind."
Kennedy was undoubtedly correct in that assessment. Furthering knowledge and understanding about the universe by increments is not nearly as inspiring a goal or as strong a competitive political masterstroke as "land a man on the moon, in this decade, and return him safely to earth." A moon mission has imagination, a clear victory point--and, as retired astronaut Story Musgrave likes to point out, all the elements of great project management: a clear focus, clear requirements, a clear goal, and a clear timeline in which to accomplish that goal.
The eight-year Apollo effort leading to the moon landing also sparked the development of all kinds of new technology: from rockets to life-support systems, from lightweight materials to protective coatings, and to really cool pens that wrote in zero gravity. It also undoubtedly inspired many school children in the 1960s to pursue engineering, in the hopes of becoming part of the grand space adventure when they grew up.
But while the moon landing was unquestionably inspirational--I still remember racing home from a camping trip to watch it on TV--and a decisive public-relations victory for the U.S. in its "space war" with the Soviet Union, it came at a price. In the late 1950s, NASA was working on other, more sophisticated ways of getting into space. The X-15 rocket plane (pictured below) incorporated exotic materials, the first throttle-controlled rocket engine and was designed to fly more than six times the speed of sound, at altitudes above 250,000 feet. Up at those altitudes, it used small bursts by hydrogen-peroxide thrust rockets for control (normal aircraft control surfaces, which depend on air pressure, would be useless outside the atmosphere) and then glided back for an unpowered landing on earth.
And yes, that's Neil Armstrong in that photo--Armstrong served as an X-15 test pilot before joining the astronaut corps.
The military was also working on a space plane project called Dyna-Soar, while other researchers at NASA worked on concepts for lifting bodies--highly efficient, if odd-shaped, spacecraft that could handle the heat of re-entry while still being controllable within the atmosphere. (see the examples below)
There was, in fact, a division within NASA between the "airplane" folks, who wanted to develop more sophisticated, reusable spacecraft that could fly into space and back, and the "rocket" folks who advocated the brute force of a rocket launcher with a capsule on top as the best (and fastest) way to get space capability. But with the tight deadline imposed by Kennedy's challenge to getting a man to the moon and back within nine years, it became clear that the more complex reusable engines and spacecraft would take too long to develop. The rockets won the day, and the funding and focus turned away from hypersonic space vehicles and space "flight."
The Space Shuttle did, in fact, incorporate some of the earlier design concepts from the airplane side of NASA--including its reliance on gliding back to an unpowered landing on earth. But concepts like a single-stage-to-orbit rocket engine, scram and ram jets for ultra-high-speed transport planes, and better reusable spacecraft designs never made it off the drawing board. If they had, we might now have commercial spaceflight vehicles hopping from Japan to Chicago on a regular basis. As it is, even the Shuttle has to rely on the brute force of disposable rocket engines to get out of the earth's atmosphere, at a cost of around half a billion dollars a pop.
The moon program also seemed to lock our collective imagination into a fixed formula for human spaceflight, and spaceflight as an engineering project, even if those missions had questionable scientific value (with notable exceptions like the launch and repair of the Hubble Space Telescope). After all, even the moon mission was primarily an engineering challenge, not a scientific research mission.
As Story Musgrave put it in the interview noted above,
We could have had multiple Voyagers landed or floating in the atmosphere on every planet and on every moon of every planet. That is what we gave up when we went with [the International Space Station]. If you sent multi-media robotic machines [into space], people would be unbelievably excited about going everywhere out there. And we could have gone everywhere. But we opted to stay in low-earth orbit and do a jobs program because we had no imagination.
Musgrave is not the only one of that opinion. John M. Logsdon, a space policy specialist who's written a new book on the subject (John F. Kennedy and the Race to the Moon), told a New York Times writer last week that despite having praised the Apollo program in an earlier book, he's since come to the conclusion that the Apollo program's impact on the space program has "on balance, been negative." Apollo, Logsdon said, was "a dead-end undertaking in terms of human travel beyond the immediate vicinity of this planet."
Certainly the human space flight program, and the International Space Station, have more than a few critics. And the money and focus on the human spaceflight side of NASA have deflected huge amounts of money and brainpower away from other research efforts. The question is ... could the situation have been different?
I'm a huge fan of the more sophisticated design ideas that languished at NASA in the post-Kennedy-challenge era, as well as many of the other technologies that could have been developed with that money. Not to mention the scientific discoveries we could have made if we'd put the effort there instead of sending crew after crew into the same orbit around the earth. The materials and mind-bending physics know-how required to build a spacecraft capable of really-distant space flight outside our galaxy still lie beyond our reach. But we might be closer if we'd put a big chunk of the human space flight budget toward that effort.
On the other hand, the prodigious Apollo funding would likely not have been approved for anything less clear, less politically impactful or less mesmerizing than putting a human on the moon. So in many ways, whether or not the Apollo money could have been better spent is a moot point. And there is something to be said--something pretty compelling--for having gotten a human off the planet, onto another celestial body, and back home again.
The issue with Apollo is just that it set expectations so strongly in one direction, and left NASA so geared up to pursue human spaceflight, that it was difficult to shift gears after the moon landing was accomplished. Important scientific and aerospace technology research has continued at numerous NASA Centers around the country (think Mars Rover, satellite and GPS technology, and a host of telescopes, safety technology, and aircraft design and efficiency improvements). But the human space flight side of NASA continued to get a big chunk of the budget pie, even after the Apollo program concluded and there wasn't another clear goal for humans to accomplish in space.
But if our focus never shifted to the amazing scientific discoveries that might have been found, it's at least in large part because what drove the Apollo program--as President Kennedy made abundantly clear in that speech 50 years ago--wasn't science. It was a strategic blow against the Soviet Union, and for the achievements of democracy, in a world where communism was seen as a real and growing threat. Period. Paragraph. End of discussion.
Still--one of the many intriguing parts of Kennedy's speech (and there are many) is how strongly he stressed to Congress and the American people that if they were not willing to sacrifice for this goal, and commit fully to its achievement, no matter what it took, then it would be better not to attempt it at all.
"If we are to go only half way, or reduce our sights in the face of difficulty, in my judgment it would be better not to go at all," Kennedy said. "There is no sense in agreeing or desiring that the United States take an affirmative position in outer space, unless we are prepared to do the work and bear the burdens to make it successful."
Of course, it was easier to say that in 1961, before NASA had as many Center and work forces whose jobs would be endangered if the nation decided that, in fact, it would rather not bear all those burdens and pay all those costs.
But 50 years later, Kennedy's point is still valid. Some of the work in low-earth orbit that NASA used to do is being handed off to private industry. The great promise of NASA's current space program is now in the field of technology advancement and exploratory science. Of course, those developments might lead, some day, to another clear goal worth pursuing in-person, an exotic, distant place brought almost within reach that's worth a mighty, focused effort for humans to go explore.
But the true challenge Kennedy threw down in that 1961 speech still applies. Without a Soviet rival to "race," and without the imperative of a cold war threat to counter, do we really care enough about space for science and exploration's sake to pay the costs and bear the burdens for that effort to bear dramatic fruit? The jury is still out on that one, in part because I don't know that the country's been asked to sacrifice much for NASA's scientific efforts. But in any event, as Kennedy said, we shouldn't attempt something halfway. We should figure out what scientific, engineering, or technology goals we really do care enough about to pursue, get excited about, and focus on carrying those through to completion--and let the rest go.
The part of that 1961 speech that Kennedy is remembered for is the moon challenge. But his challenge to Congress and the nation to think about whether or not space was worth the effort, and to walk away unless "every scientist, every engineer, every serviceman, every technician, contractor, and civil servant gives his pledge that this nation will move forward ... [without] undue work stoppages, inflated costs of material or talent, wasteful interagency rivalries, or a high turnover of key personnel" is the part of the speech that has the most lasting relevance.
What goal, if any, do we care enough about to commit to that fully? Fifty years later, the question still lingers in the air, awaiting an answer again.
“Well, you’re just special. You’re American,” remarked my colleague, smirking from across the coffee table. My other Finnish coworkers, from the school in Helsinki where I teach, nodded in agreement. They had just finished critiquing one of my habits, and they could see that I was on the defensive.
I threw my hands up and snapped, “You’re accusing me of being too friendly? Is that really such a bad thing?”
“Well, when I greet a colleague, I keep track,” she retorted, “so I don’t greet them again during the day!” Another chimed in, “That’s the same for me, too!”
Unbelievable, I thought. According to them, I’m too generous with my hellos.
When I told them I would do my best to greet them just once every day, they told me not to change my ways. They said they understood me. But the thing is, now that I’ve viewed myself from their perspective, I’m not sure I want to remain the same. Change isn’t a bad thing. And since moving to Finland two years ago, I’ve kicked a few bad American habits.
His paranoid style paved the road for Trumpism. Now he fears what’s been unleashed.
Glenn Beck looks like the dad in a Disney movie. He’s earnest, geeky, pink, and slightly bulbous. His idea of salty language is bullcrap.
The atmosphere at Beck’s Mercury Studios, outside Dallas, is similarly soothing, provided you ignore the references to genocide and civilizational collapse. In October, when most commentators considered a Donald Trump presidency a remote possibility, I followed audience members onto the set of The Glenn Beck Program, which airs on Beck’s website, theblaze.com. On the way, we passed through a life-size replica of the Oval Office as it might look if inhabited by a President Beck, complete with a portrait of Ronald Reagan and a large Norman Rockwell print of a Boy Scout.
Why the ingrained expectation that women should desire to become parents is unhealthy
In 2008, Nebraska decriminalized child abandonment. The move was part of a "safe haven" law designed to address increased rates of infanticide in the state. Like other safe-haven laws, parents in Nebraska who felt unprepared to care for their babies could drop them off in a designated location without fear of arrest and prosecution. But legislators made a major logistical error: They failed to implement an age limitation for dropped-off children.
Within just weeks of the law passing, parents started dropping off their kids. But here's the rub: None of them were infants. A couple of months in, 36 children had been left in state hospitals and police stations. Twenty-two of the children were over 13 years old. A 51-year-old grandmother dropped off a 12-year-old boy. One father dropped off his entire family -- nine children from ages one to 17. Others drove from neighboring states to drop off their children once they heard that they could abandon them without repercussion.
Trinidad has the highest rate of Islamic State recruitment in the Western hemisphere. How did this happen?
This summer, the so-called Islamic State published issue 15 of its online magazine Dabiq. In what has become a standard feature, it ran an interview with an ISIS foreign fighter. “When I was around twenty years old I would come to accept the religion of truth, Islam,” said Abu Sa’d at-Trinidadi, recalling how he had turned away from the Christian faith he was born into.
At-Trinidadi, as his nom de guerre suggests, is from the Caribbean island of Trinidad and Tobago (T&T), a country more readily associated with calypso and carnival than the “caliphate.” Asked if he had a message for “the Muslims of Trinidad,” he condemned his co-religionists at home for remaining in “a place where you have no honor and are forced to live in humiliation, subjugated by the disbelievers.” More chillingly, he urged Muslims in T&T to wage jihad against their fellow citizens: “Terrify the disbelievers in their own homes and make their streets run with their blood.”
Even in big cities like Tokyo, small children take the subway and run errands by themselves. The reason has a lot to do with group dynamics.
It’s a common sight on Japanese mass transit: Children troop through train cars, singly or in small groups, looking for seats.
They wear knee socks, polished patent-leather shoes, and plaid jumpers, with wide-brimmed hats fastened under the chin and train passes pinned to their backpacks. The kids are as young as 6 or 7, on their way to and from school, and there is nary a guardian in sight.
A popular television show called Hajimete no Otsukai, or My First Errand, features children as young as two or three being sent out to do a task for their family. As they tentatively make their way to the greengrocer or bakery, their progress is secretly filmed by a camera crew. The show has been running for more than 25 years.
A professor of cognitive science argues that the world is nothing like the one we experience through our senses.
As we go about our daily lives, we tend to assume that our perceptions—sights, sounds, textures, tastes—are an accurate portrayal of the real world. Sure, when we stop and think about it—or when we find ourselves fooled by a perceptual illusion—we realize with a jolt that what we perceive is never the world directly, but rather our brain’s best guess at what that world is like, a kind of internal simulation of an external reality. Still, we bank on the fact that our simulation is a reasonably decent one. If it wasn’t, wouldn’t evolution have weeded us out by now? The true reality might be forever beyond our reach, but surely our senses give us at least an inkling of what it’s really like.
The same part of the brain that allows us to step into the shoes of others also helps us restrain ourselves.
You’ve likely seen the video before: a stream of kids, confronted with a single, alluring marshmallow. If they can resist eating it for 15 minutes, they’ll get two. Some do. Others cave almost immediately.
This “Marshmallow Test,” first conducted in the 1960s, perfectly illustrates the ongoing war between impulsivity and self-control. The kids have to tamp down their immediate desires and focus on long-term goals—an ability that correlates with their later health, wealth, and academic success, and that is supposedly controlled by the front part of the brain. But a new study by Alexander Soutschek at the University of Zurich suggests that self-control is also influenced by another brain region—and one that casts this ability in a different light.
“All the world has failed us,” a resident of the Syrian city of Aleppo told the BBC this week, via a WhatsApp audio message. “The city is dying. Rapidly by bombardment, and slowly by hunger and fear of the advance of the Assad regime.”
In recent weeks, the Syrian military, backed by Russian air power and Iran-affiliated militias, has swiftly retaken most of eastern Aleppo, the last major urban stronghold of rebel forces in Syria. Tens of thousands of besieged civilians are struggling to survive and escape the fighting, amid talk of a rebel retreat. One of the oldest continuously inhabited cities on earth, the city of the Silk Road and the Great Mosque, of muwashshah and kibbeh with quince, of the White Helmets and Omran Daqneesh, is poised to fall to Bashar al-Assad and his benefactors in Moscow and Tehran, after a savage four-year stalemate. Syria’s president, who has overseen a war that has left hundreds of thousands of his compatriots dead, will inherit a city robbed of its human potential and reduced to rubble.
Why has Trump shown such eagerness to select former military brass for his Cabinet? The reasons may be both pragmatic and political.
Donald Trump didn’t always speak highly of military brass. “I know more about ISIS than the generals do,” he said in fall 2016. “Believe me.” In September, he added, “I think under the leadership of Barack Obama and Hillary Clinton, the generals have been reduced to rubble. They have been reduced to a point where it’s embarrassing for our country…. And I can just see the great—as an example—General George Patton spinning in his grave as ISIS we can’t beat.”
But Trump’s disdain had a caveat: “I have great faith in the military. I have great faith in certain of the commanders, certainly.”
These days, he’s leaning toward the second pole. Already, Trump has selected three retired generals for Cabinet-level jobs. On Tuesday, he formally announced that he’s nominating retired Marine General James Mattis as defense secretary. On Wednesday, multiple outlets reported that he has selected John Kelly, another retired Marine general, as secretary of homeland security. Former Lieutenant General Michael Flynn got the nod as national security adviser on November 17.
A recent study shows that people who simply ate more fiber lost about as much weight as those who went on a complicated diet.
By this time of year, many peoples’ best-laid New Year’s Resolutions have died, just seven short weeks after they were born. One reason why it’s difficult to lose weight—the most common resolution—is that dieting is so confusing.
For instance, the American Heart Association's recommended diet is one of the most effective food plans out there. It’s also one of the most complicated. It requires, according to a recent study, “consuming vegetables and fruits; eating whole grains and high-fiber foods; eating fish twice weekly; consuming lean animal and vegetable proteins; reducing intake of sugary beverages; minimizing sugar and sodium intake; and maintaining moderate to no alcohol intake.” On top of that, adherents should derive half of their calories from carbs, a fifth from protein, and the rest from fat—except just 7 percent should be saturated fat. (Perhaps the goal is to keep people busy doing long division so they don't have time to eat food.)
