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.
Orr: “It’s a pleasure to meet you, Your Grace. My name is Tyrion Lannister.”
At last! I know I speak for quite a few book readers when I say that pretty much the only thing that kept me going through the eleventy thousand discursive, digressive pages of George R. R. Martin’s fifth tome, A Dance With Dragons, was the promise of Tyrion finally meeting up with Daenerys Targaryen. And, of course, after eleventy thousand pages, it never happened. So on behalf of myself and everyone else who sacrificed sleep, work, family, and friends waiting for this moment, let me say thank you, David Benioff and D. B. Weiss. Bonus points for what seemed to be a cameo by Strong Belwas (a book character who was written out of the show) as the nameless fighter who freed Tyrion from his chains.
The Islamic State is no mere collection of psychopaths. It is a religious group with carefully considered beliefs, among them that it is a key agent of the coming apocalypse. Here’s what that means for its strategy—and for how to stop it.
What is the Islamic State?
Where did it come from, and what are its intentions? The simplicity of these questions can be deceiving, and few Western leaders seem to know the answers. In December, The New York Times published confidential comments by Major General Michael K. Nagata, the Special Operations commander for the United States in the Middle East, admitting that he had hardly begun figuring out the Islamic State’s appeal. “We have not defeated the idea,” he said. “We do not even understand the idea.” In the past year, President Obama has referred to the Islamic State, variously, as “not Islamic” and as al-Qaeda’s “jayvee team,” statements that reflected confusion about the group, and may have contributed to significant strategic errors.
Some fans are complaining that Zack Snyder’s envisioning of the Man of Steel is too grim—but it’s less a departure than a return to the superhero’s roots.
Since the official teaser trailer for Batman v Superman: Dawn of Justice debuted online in April, fans and critics alike have been discussing the kind of Superman Zack Snyder is going to depict in his Man of Steel sequel. The controversy stems from Snyder’s decision to cast Superman as a brooding, Dark Knight-like character, who cares more about beating up bad guys than saving people. The casting split has proved divisive among Superman fans: Some love the new incarnation, citing him as an edgier, more realistic version of the character.
But Snyder’s is a different Superman than the one fans grew up with, and many have no problem expressing their outrage over it. Even Mark Waid, the author of Superman: Birthright (one of the comics the original film is based on), voiced his concern about Man of Steel’s turn toward bleakness when it came out in 2013:
The country’s political dysfunction has undermined all efforts to build an effective fighting force.
The Obama Administration has run out of patience with Iraq’s Army. On Sunday, Secretary of Defense Ashton Carter appeared on CNN’s “State of the Union” to discuss the recent fall of Ramadi, one of Iraq’s major cities, to ISIS. Despite possessing substantial advantages in both numbers and equipment, he said, the Iraqi military were unable to prevent ISIS forces from capturing the city.
“That says to me and, I think, to most of us, that we have an issue with the will of the Iraqis to fight ISIL and defend themselves.”
Carter’s frustrations are shared by his boss. When asked about the war against ISIS in a recent interview with the Atlantic’s Jeffrey Goldberg, President Obama said that “if the Iraqis are not willing to fight for the security of their country, then we cannot do it for them.”
New research confirms what they say about nice guys.
Smile at the customer. Bake cookies for your colleagues. Sing your subordinates’ praises. Share credit. Listen. Empathize. Don’t drive the last dollar out of a deal. Leave the last doughnut for someone else.
Sneer at the customer. Keep your colleagues on edge. Claim credit. Speak first. Put your feet on the table. Withhold approval. Instill fear. Interrupt. Ask for more. And by all means, take that last doughnut. You deserve it.
Follow one of those paths, the success literature tells us, and you’ll go far. Follow the other, and you’ll die powerless and broke. The only question is, which is which?
Of all the issues that preoccupy the modern mind—Nature or nurture? Is there life in outer space? Why can’t America field a decent soccer team?—it’s hard to think of one that has attracted so much water-cooler philosophizing yet so little scientific inquiry. Does it pay to be nice? Or is there an advantage to being a jerk?
Changing neighborhoods may be a class issue, but in America, that means it's also a racial one.
Ask city-dwellers to describe what, precisely, gentrification is you’ll get an array of answers. The term is a murky one, used to describe the many different ways through which money and development enter poorer or less developed neighborhoods, changing them both economically and demographically.
For some, gentrification and gentrifiers are inherently bad—pushing out residents who are often older, poorer, and darker than the neighborhood’s new occupants. For others, a new group of inhabitants brings the possibility of things residents have long hoped for, better grocery stores, new retail, renovations, and an overall revitalization that often eludes low-income neighborhoods.
Rebel groups that employ terror in civil wars seldom win or gain concessions—but they tend to prolong conflicts, a new paper finds.
Nearly 14 years into the war on terror, there are signs of terrorism all around us, from Memorial Day tributes to the victims of the wars in Iraq and Afghanistan to the raging congressional debate over reauthorizing the Patriot Act.
Yet some of the most basic information about terrorism remains surprisingly elusive. For example: Does it work?
There have been some attempts at answering the question, but many of them are either largely anecdotal or geographically constrained. Other studies have focused on international terror. But as political scientist Page Fortna of Columbia University notes, the vast majority of terrorism isn’t transnational—it’s localized, utilized in the context of civil wars and fights for territorial control. Many of the intractable conflicts the U.S. is involved in today fit this definition: the fighting between ISIS, Jabhat al-Nusra, and other groups in Iraq and Syria; the Boko Haram insurgency in Nigeria; al-Shabab’s terrorism in Somalia and Kenya; Yemen’s civil war; the Israel-Palestinian conflict. Is terrorism an effective tool when used in those conflicts?
In an interview, the U.S. president ties his legacy to a pact with Tehran, argues ISIS is not winning, warns Saudi Arabia not to pursue a nuclear-weapons program, and anguishes about Israel.
On Tuesday afternoon, as President Obama was bringing an occasionally contentious but often illuminating hour-long conversation about the Middle East to an end, I brought up a persistent worry. “A majority of American Jews want to support the Iran deal,” I said, “but a lot of people are anxiety-ridden about this, as am I.” Like many Jews—and also, by the way, many non-Jews—I believe that it is prudent to keep nuclear weapons out of the hands of anti-Semitic regimes. Obama, who earlier in the discussion had explicitly labeled the supreme leader of Iran, Ayatollah Ali Khamenei, an anti-Semite, responded with an argument I had not heard him make before.
“Look, 20 years from now, I’m still going to be around, God willing. If Iran has a nuclear weapon, it’s my name on this,” he said, referring to the apparently almost-finished nuclear agreement between Iran and a group of world powers led by the United States. “I think it’s fair to say that in addition to our profound national-security interests, I have a personal interest in locking this down.”
Think that these odd finger-shoes are "bullshit"? Think again.
I gather that there is much gleeful stomping on the grave image of Vibram and the weirdo/chic "finger shoes" it has popularized, because the company has settled a suit claiming the shoes offered no health benefits. That's me and one of my sons, modeling Vibram shoes, in the picture above. I'll let you figure out the extremities.
That picture comes from four years ago. I'd been running regularly for many decades before that, but since the early 2000s I'd been vexed by one wear-and-tear problem after another. Never involving the knees, miraculously; most frequently afflicting the Achilles tendons.
Then, as I shifted to Vibram shoes, I also shifted to what has been (again miraculously) a multi-year stint of injury-free running. True, my change of footwear coincided with some other injury-buffering changes: Always taking at least a day off between runs. Opting for rubberized tracks rather than hard paved roads. Stopping as soon as something started to hurt, rather than "running through" the distress; and generally acting like a senior-status wimp.
