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 Democratic insurgent’s campaign is losing steam—but his supporters are not ready to give up.
SANTA MONICA, Calif.—This is how a revolution ends: its idealism tested, its optimism drained, its hope turned to bitterness.
But if Bernie Sanders’s revolution has run aground in California, which will be one of the last states to vote in the Democratic primary on June 7, he was not about to admit it here, where thousands gathered on a sun-drenched high-school football field of bright green turf.
“We are going to win here in California!” Sanders said, to defiant cheers. In the audience, a man waved a sign that said, “Oh HILL no!”
This is Sanders’s last stand, according to the official narrative of the corrupt corporate media, and if there is anything we have learned in the past year, it is the awesome power of the official narrative—the self-reinforcing drumbeat that dictates everything.
A rock structure, built deep underground, is one of the earliest hominin constructions ever found.
In February 1990, thanks to a 15-year-old boy named Bruno Kowalsczewski, footsteps echoed through the chambers of Bruniquel Cave for the first time in tens of thousands of years.
The cave sits in France’s scenic Aveyron Valley, but its entrance had long been sealed by an ancient rockslide. Kowalsczewski’s father had detected faint wisps of air emerging from the scree, and the boy spent three years clearing away the rubble. He eventually dug out a tight, thirty-meter-long passage that the thinnest members of the local caving club could squeeze through. They found themselves in a large, roomy corridor. There were animal bones and signs of bear activity, but nothing recent. The floor was pockmarked with pools of water. The walls were punctuated by stalactites (the ones that hang down) and stalagmites (the ones that stick up).
Nicholas and Erika Christakis stepped down from their positions in residential life months after student activists called for their dismissal over a Halloween kerfuffle.
Last fall, student protesters at Yale University demanded that Professor Nicholas Christakis, an academic star who has successfully mentored Ivy League undergraduates for years, step down from his position as faculty-in-residence at Silliman College, along with his wife, Erika Christakis, who shared in the job’s duties.
The protesters had taken offense at an email sent by Erika Christakis.
Dogged by the controversy for months, the couple finally resigned their posts Wednesday. Because the student protests against them were prompted by intellectual speech bearing directly on Erika Christakis’s area of academic expertise, the outcome will prompt other educators at Yale to reflect on their own positions and what they might do or say to trigger or avoid calls for their own resignations. If they feel less inclined toward intellectual engagement at Yale, I wouldn’t blame them.
A gay-rights amendment takes down a House appropriations bill, and with it might go the speaker’s grand plan to revive the congressional spending process.
The state-by-state fight for gay and transgender rights has reached the floor of the House of Representatives, and it is ruining Speaker Paul Ryan’s carefully-laid plans for reviving the congressional spending process.
Republicans and Democrats voted down an annual bill appropriating funds for energy and water programs on Thursday morning after Democrats succeeded in attaching an amendment to bar federal contractors from discriminating on the basis of sexual orientation or gender identity. The provision drew bipartisan support only days after GOP leaders scrambled to defeat a similar amendment that Democrats tried to add to another appropriations bill—an embarrassing moment in which rank-and-file Republicans were cajoled into flipping their votes so the measure would fail. The attempt succeeded this time, but it became moot hours later when the underlying $37.4 billion measure went down in a landslide vote of 305-112, with majorities of both parties voting against it. The meltdown happened so quickly that it appeared to catch the House Appropriations Committee, which wrote the bill, off guard. The committee sent out a statement from Chairman Hal Rogers with a headline heralding its passage just minutes before it was voted down; it was quickly rescinded.
Narcissism, disagreeableness, grandiosity—a psychologist investigates how Trump’s extraordinary personality might shape his possible presidency.
In 2006, Donald Trump made plans to purchase the Menie Estate, near Aberdeen, Scotland, aiming to convert the dunes and grassland into a luxury golf resort. He and the estate’s owner, Tom Griffin, sat down to discuss the transaction at the Cock & Bull restaurant. Griffin recalls that Trump was a hard-nosed negotiator, reluctant to give in on even the tiniest details. But, as Michael D’Antonio writes in his recent biography of Trump, Never Enough, Griffin’s most vivid recollection of the evening pertains to the theatrics. It was as if the golden-haired guest sitting across the table were an actor playing a part on the London stage.
“It was Donald Trump playing Donald Trump,” Griffin observed. There was something unreal about it.
The 2016 campaign has revealed an America of stark division and mutual animosity.
ANAHEIM, Calif.—The police form a column that stretches across eight lanes of road and two sidewalks. There are dozens of them—Orange County deputies in olive-green uniforms and helmets with shields. A group of cops on horses occupies the middle of the street; they are flanked on either side by several rows of police on foot, holding their truncheons forward and yelling, over and over, “DISPERSE! LEAVE THE AREA!” as they march forward.
The cops are here, at the Trump rally, to prevent trouble.
A black man in a wifebeater shirt is waving a brightly colored homemade poster that reads, “LATINOS FOR BERNIE.” He is arguing heatedly with a middle-aged white man in a yellow hard hat with TRUMP written on it. Most of the other Trump supporters have been held back by police a block up the road.
A Greek archaeologist says he has located the classical philosopher’s final resting place.
A Greek archaeologist announced Thursday he has located the tomb of Aristotle, the classical philosopher whose voluminous writings shaped the intellectual trajectory of Western civilization.
Konstantinos Sismanidis, the archaeologist who excavated the find, announced the discovery at a conference in Thessalonica. The site is located in Stagira, a village in Greek Macedonia where Aristotle was born.
“We had found the tomb,” he said. “We’ve now also found the altar referred to in ancient texts, as well as the road leading to the tomb, which was very close to the city’s ancient marketplace within the city settlement.”
Although the evidence of whose tomb it was is circumstantial, several characteristics — its location and panoramic view; its positioning at the center of a square marble floor; and the time of its construction, estimated to be at the very beginning of the Hellenistic period, which started after the death of Aristotle’s most famous student, Alexander the Great, in 323 B.C. — “all lead to the conclusion that the remains of the arched structure are part of what was once the tomb-shrine of Aristotle,” Mr. Sismanidis said.
A year after Obama saluted the families for their spirit of forgiveness, his administration seeks the death penalty for the Charleston shooter.
On Tuesday, Attorney General Loretta Lynch announced she would seek the death penalty for Dylann Roof. It has not been a year since Roof walked into Emanuel African Methodist Episcopal Church and murdered nine black people as they worshipped. Roof justified this act of terrorism in chillingly familiar language—“You rape our women and you’re taking over our country.” The public display of forgiveness offered to Roof by the families of the victims elicited bipartisan praise from across the country. The president saluted the families for “an expression of faith that is unimaginable but that reflects the goodness of the American people.” How strange it is to see that same administration, and these good people, who once saluted the forgiveness of Roof, presently endorse his killing.
In recent years, the idea that educators should be teaching kids qualities like grit and self-control has caught on. Successful strategies, though, are hard to come by.
In 2013, for the first time, a majority of public-school students in this country—51 percent, to be precise—fell below the federal government’s low-income cutoff, meaning they were eligible for a free or subsidized school lunch. It was a powerful symbolic moment—an inescapable reminder that the challenge of teaching low-income children has become the central issue in American education.
The truth, as many American teachers know firsthand, is that low-income children can be harder to educate than children from more-comfortable backgrounds. Educators often struggle to motivate them, to calm them down, to connect with them. This doesn’t mean they’re impossible to teach, of course; plenty of kids who grow up in poverty are thriving in the classroom. But two decades of national attention have done little or nothing to close the achievement gap between poor students and their better-off peers.
