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.
The First Lady took to the stage at the Democratic National Convention, and united a divided hall.
Most convention speeches are forgotten almost before they’re finished. But tonight in Philadelphia, Michelle Obama delivered a speech that will be replayed, quoted, and anthologized for years. It was as pure a piece of political oratory as this campaign has offered, and instantly entered the pantheon of great convention speeches.
Obama stepped out onto a stage in front of a divided party, including delegates who had booed almost every mention of the presumptive nominee. And she delivered a speech that united the hall, bringing it to its feet.
She did it, moreover, her own way—forming a striking contrast with the night’s other speakers. She did it without shouting at the crowd. Without overtly slamming Republicans. Without turning explicitly negative. Her speech was laden with sharp barbs, but she delivered them calmly, sometimes wryly, biting her lower lip, hitting her cadence. It was a masterful performance.
A 30-step review of the mayhem in Philadelphia, and what Clinton’s convention says about the future of the American political system.
Hillary Clinton, her advisers, and their allies at the Democratic National Committee watched Donald Trump’s nominating convention in Cleveland with smug satisfaction.
Team Trump had insulted Ohio’s governor, approved a Melania Trump speech that plagiarized Michelle Obama, lied about the plagiarism, and allowed Ted Cruz to expose party divisions in a prime-time speech.
“Hey @Reince,” Democratic National Committee chairwoman Debbie Wasserman Schultz tweeted GOP chairman Reince Priebus. “I’m in Cleveland if you need another chair to keep your convention in order.”
Schultz reflected the Democratic establishment’s false sense of security. Headed to their convention in Philadelphia, Democrats felt more united than Republicans, better organized, and less vulnerable to the long-term disruption of a populist insurgency.
All hell broke loose.
WikiLeaks released 20,000 emails stolen from DNC computers, proof of the worst-kept secret in Democratic politics: The party worked against socialist-populist Bernie Sanders to ease Hillary Clinton’s path to the nomination. The FBI said it would investigate whether Russia hacked the DNC to influence the U.S. election.
All hell broke loose.
“Lock her up!” chanted Democratic activists in the streets of Philadelphia. These Sanders supporters carried signs and wore T-shirts that called for Clinton’s indictment, channeling those GOP delegates in Cleveland who drew rebukes for defying old rules of political decorum.
Schultz cut a deal with the Clinton team to resign, effective upon the conclusion of the convention. She planned to open and close the gathering with remarks lauding her leadership.
All hell broke loose.
Addressing delegates from her home state of Florida, Shultz chastised an unruly crowd carrying signs reading “Division!” and “EMAILS.” She said, “We know that the voices in this room that are standing up and being disruptive, we know that is not the Florida we know.”
“Shame! Shame! Shame!” crowd members chanted. Schultz scurried out of the room.
Sanders himself tried to prevent a show of disunity on the convention floor, pleading with his supporters to back Clinton. Having promised his followers “a revolution,” he now fed them bitter pragmatism. “Brothers and sisters,” Sanders said, “this is the real world that we live in.”
All hell broke loose.
While the streets filled with a sweaty mass of angry Sanders supporters—mostly young and white and disconnected from the political system—the Clinton team told Shultz she couldn’t address the convention.
Sanders sent his supporters a text message, urging them not to protest on the convention floor.
All hell broke loose.
As the convention came to order, hundreds of Democrats protested outside. “No, no, DNC—we won’t vote for Hillary!”
Inside, Cynthia Hale mentioned Clinton’s name during the opening prayer. Some delegates booed, others chanted for Sanders.
There would be more protests.
Eventually, Clinton likely will regain control of her convention. Like in Cleveland, the desire to defeat a hated enemy will overcome internal differences. The blues will line up against the reds, Wall Street will support both teams, Clinton will win in November, and the status quo will declare victory over change. Populist unrest will broaden and intensify.
Or Trump will win. He won’t keep his promises, because he never does. He won’t make America any greater than it already is. He might make it worse. The status quo will declare victory over change. Populist unrest will broaden and intensify.
Whether it’s Clinton or Trump, historians will note how a billionaire celebrity took over the GOP with an anti-trade, anti-immigration nativism, setting fire to the political playbook that guided campaigns for the last half of the 20th century and the first decade of the 21st.
Today will be long remembered, too. Sanders couldn’t calm the churning of his supporters and, as in a mutiny aboard a pirate ship, the deckhands have seized control from the captain.
This could be the start of something big inside the Democratic Party. What if, for instance, Sanders’s coalition banded together with Black Lives Matters to create Tea Party-like takeover of the Democratic Party?
People have witnessed disruption in the retail, entertainment, and financial industries—in virtually every institution except for government and politics. In an era of choice and technological efficiency, the American voter is given a binary choice and gridlocked government.
Most Americans want something better than what the Democratic-Republican duopoly crams down their throats.
They’re mad as hell and, as evidenced in Cleveland and Philadelphia, they’re just starting to realize how powerful they are. They don’t need to take it anymore.
The Vermont senator closed the first night of the Democratic National Convention in Philadelphia with a show of unity, but his supporters weren’t necessarily with him.
After a contentious start to the Democratic convention, Bernie Sanders took the stage at the end of the night on Monday, to an adoring crowd. By the time he left, he did not seem to have succeeded in convincing his most ardent supporters to stand with Hillary Clinton.
Sanders framed the election as a clear choice between the threat of Donald Trump in the White House, and the far better outcome of a President Hillary Clinton. “We need leadership, which brings our people together and makes us stronger—not leadership which insults Latinos, Muslims, women, African Americans, and veterans and divides us up,” Sanders warned. “By these measures, any objective observer will conclude that—based on her ideas and her leadership—Hillary Clinton must become the next president of the United States. The choice is not even close.” The line met with loud cheers and applause.
As the Democratic National Convention prepares to kick off, a massive leak of hacked emails renews old questions about how the Clintons and their associates operate.
PHILADELPHIA—What’s with Hillary Clinton and email? The Democratic presidential nominee who shattered her credibility over a rogue email system while serving as secretary of state now must deal with an electronic snafu at the Democratic National Committee.
Among 20,000 DNC emails posted by WikiLeaks on the eve of Clinton’s nominating convention, there are scores in which party employees criticized and mocked Bernie Sanders during his primary campaign against Clinton. (Caveat: We don’t formally know the emails are authentic).
The email dump jeopardizes Clinton’s ability to unify the party in Philadelphia and avoid the public fratricide that spoiled Donald Trump’s convention in Cleveland. While some of the DNC emails criticized Clinton, the overwhelming number of anti-Sanders correspondences create an indelible impression that the DNC violated its oath of neutrality.
The pressures of national academic standards have pushed character education out of the classroom.
A few months ago, I presented the following scenario to my junior English students: Your boyfriend or girlfriend has committed a felony, during which other people were badly harmed. Should you or should you not turn him or her into the police?
The class immediately erupted with commentary. It was obvious, they said, that loyalty was paramount—not a single student said they’d “snitch.” They were unequivocally unconcerned about who was harmed in this hypothetical scenario. This troubled me.
This discussion was part of an introduction to an essay assignment about whether Americans should pay more for ethically produced food. We continued discussing other dilemmas, and the kids were more engaged that they’d been in weeks, grappling with big questions about values, character, and right versus wrong as I attempted to expand their thinking about who and what is affected—and why it matters—by their caloric choices.
Ask yourself, is all that wasted time really rewarding? And other tips from Charles Duhigg, who wrote the book on productivity.
Why is it that the more work I have to do, the more the Internet beckons me into its endless maw of distraction? Oh Lord, I will say, appealing both to myself and to whatever blog-God might be listening, I have an hour to finish this article.
But first, isn’t this Tasty video fascinating? I’ve never thought about making buffalo-fried cheese nuggets before, but now that I’ve watched a pair of disembodied hands prepare them so expertly, I should definitely head over to Amazon and Prime me some buffalo sauce.
This is how I found myself, exhausted after leaving work at 8 p.m. one day recently, flopping onto my bed, still in my pencil skirt, and clicking open a horrific, traffic-mongering slideshow linked from the bottom of an article I was reading. It was about Stars Without Makeup or What Child Stars Look Like Now or some other rancid meat for my hungry lizard brain.
Hillary Clinton is running as the candidate of continuity—but Bernie Sanders, Elizabeth Warren, and most white Democrats think America is headed in the wrong direction.
Many commentators, watching the two party’s conventions, have noted that Democrats and Republicans seemed to describing different countries. But if you listened carefully last night, you heard two groups of Democrats describing different countries too.
The night began with Michelle Obama, who said, “I wake up every morning in a house that was built by slaves. And I watch my daughters—two beautiful intelligent black young women—play with the dog on the White House lawn. And because of Hillary Clinton, my daughters and all of our sons and daughters now take for granted that a woman can be president of the United States. Don't let anyone ever tell you that this country is not great. That somehow we need to make it great again. Because this right now is the greatest country on Earth.”
The president’s belief in policies that can benefit all Americans is being repudiated by voters, in favor of a vision of politics as a zero-sum game.
The 2016 presidential race represents a vivid rejection of the Obama style. This is easy to miss: His approval ratings are climbing, and Hillary Clinton won the Democratic primary by running as his successor. But the two most dramatic and portentous campaigns of the year, Donald Trump’s vertiginous win and Bernie Sanders’s astonishing insurgency, both flew in the face of the Obama era’s premises.
The Obama style had two pillars. He brought to apotheosis the American political tradition of redemptive constitutionalism. This is the creed of Abraham Lincoln’s Gettysburg Address and Second Inaugural, Martin Luther King Jr.’s “I Have a Dream” speech, and Lyndon Baines Johnson’s nationally televised speech on the Voting Rights Acts of 1965, in which he promised, “we shall overcome.” Redemptive constitutionalism holds that democracy and equal freedom really are the nation’s foundations, that slavery and Jim Crow were terrible deviations from these principles, and that, if we manage to take them seriously, to live by them, Americans will finally be free together.
Physicists can’t agree on whether the flow of future to past is real or a mental construct.
Einstein once described his friend Michele Besso as “the best sounding board in Europe” for scientific ideas. They attended university together in Zurich; later they were colleagues at the patent office in Bern. When Besso died in the spring of 1955, Einstein—knowing that his own time was also running out—wrote a now-famous letter to Besso’s family. “Now he has departed this strange world a little ahead of me,” Einstein wrote of his friend’s passing. “That signifies nothing. For us believing physicists, the distinction between past, present, and future is only a stubbornly persistent illusion.”
Einstein’s statement was not merely an attempt at consolation. Many physicists argue that Einstein’s position is implied by the two pillars of modern physics: Einstein’s masterpiece, the general theory of relativity, and the Standard Model of particle physics. The laws that underlie these theories are time-symmetric—that is, the physics they describe is the same, regardless of whether the variable called “time” increases or decreases. Moreover, they say nothing at all about the point we call “now”—a special moment (or so it appears) for us, but seemingly undefined when we talk about the universe at large. The resulting timeless cosmos is sometimes called a “block universe”—a static block of space-time in which any flow of time, or passage through it, must presumably be a mental construct or other illusion.
Close your eyes and imagine that ahacking group backed by Russian President Vladimir Putin broke into the email system of a major U.S. political party. The group stole thousands of sensitive messages and then published them through an obliging third party in a way that was strategically timed to influence the United States presidential election. Now open your eyes, because it looks like that’s what just happened.
On Friday, Wikileaks published 20,000 emails stolen from the Democratic National Committee. They reveal, among other things, thuggish infighting, a push by a top DNC official to use Bernie Sanders’s religious convictions against him in the South, and attempts to strong-arm media outlets. In other words, they reveal the Washington campaign monster for what it is.
