Opportunity's View January 24, 2012 (NASA)
On January 25, 2004, a robotic rover called Opportunity landed on the surface of Mars, our closest neighbor planet. Opportunity’s life story is a good model for thinking about our own human goals. It took more than five months and more than 34 million miles to get there, but that day marked the beginning of the rover’s real work. The next 21-plus miles has been the exciting part of the journey for scientists. The six-wheeled, solar-powered rover was designed to last 90 Martian days, which are just over 39 minutes longer than Earth days.
By its second day on Mars, Opportunity had a joint problem with a robotic arm that is supposed to be stowed when it moves. But the rover—and NASA—made do and eventually developed a way to move safely without stowing the arm. For months in 2005, Opportunity was stuck in the sand. Again, the rover—and NASA—patiently inched around and eventually started roving again.
NASA Watches Opportunity Land
All this time, Opportunity has been collecting soil samples, monitoring the climate, and sending back amazing photographs of the Martian landscape. The rover is basically a moving science mini-laboratory. It x-rays and performs microscopic imaging of rock and soil samples, then sends analyses of constituent elements back to Earth. Its Miniature Thermal Emission Spectrometer examines rocks and soil to figure out how they were formed. Scientists are especially interested to know whether and when water may have existed on Mars. In December, NASA announced that Opportunity had examined what seemed to be gypsum deposited in veins by water.
As of this month, seven years after its landing, Opportunity sits on the north end of Cape York, which is on the rim of Endeavour Crater. The rover is still looking around and conducting measurements, including Doppler tracking. The robotic arm is still working; it positioned the Alpha Particle X-ray Spectrometer on January 12.
Opportunity's Path as of December 2011
Opportunity’s twin, called Spirit, landed three weeks before Opportunity on January 4, 2004. Before the end of the month, Spirit faced a flash memory problem. NASA spent ten days reformatting, patching, and testing in order to fix the problem. Luckily, the fix worked and was applied to Opportunity as well. Even after Spirit got stuck in 2009, the rover continued to send back information. NASA’s final contact with Spirit was on March 10, 2010, more than six years after its landing. A little bit of failure goes a long way to success.
Curiosity launched on November 26, 2011. It is currently cruising (it’s in the cruise phase of the mission) and will arrive on Mars after 193 more days, in August. This rover is much bigger than its twin predecessors and will check out the Red Planet in ways that will help us plan a mission to put human beings on the surface of Mars. Of course, Curiosity will live up to its name by studying the planet’s geological evolution, radiation levels, and chemical makeup.

Few people are as enthusiastic about the Mars rovers as Ken Kremer. He does a lot of work processing the images that Mars rovers send back. Read his Lofty Ambitions guest post HERE. See his work at Universe Today HERE and HERE.
To read Anna’s very different take on the Mars rovers and how they can inspire a writing life, read her guest post “Curiouser and Curiouser” at Chandra Hoffman’s blog HERE.
As we celebrate today’s anniversary of Opportunity’s landing, consider the meaning of that word. John F. Kennedy once pointed out that the Chinese ideogram for the word crisis is composed of two characters, one meaning danger but the other meaning opportunity. We’re not sure we should learn Chinese from Kennedy, but the notion points to the relationship between failure and success about which we’ve written before here at Lofty Ambitions. What is the set of circumstances or conditions that will make it possible to accomplish something? How will we create our next opportunity, perhaps inch our way out of a metaphorical sand dune or take care of that all too real bum shoulder joint? Sometimes, it takes 34 million miles to get where you need to be, only to find out that the fun is in the next 21 miles of meandering. Is there an opportunity knocking—or knocking you over?

On Wednesday, we usually have a new post. In fact, we’ve never missed a regular Wednesday post in 565 days. This week, we had something planned about failure as part of the process in some big accomplishments. Instead, we’re participating in the blackout to oppose SOPA and support a free and open Internet.
We want to make it clear that our decision is not a stance in support of Internet piracy nor is it a statement against the rights of content creators like ourselves. Lofty Ambitions blog abides by copyright law. All our posts are original work by the two of us or by the guest bloggers invited to submit their original work. We retain the rights to what we write, and a guest blogger reacquires all rights to his or her work once we post it so that he or she can, say, include that write-up in a future book (with, we hope, acknowledgement). In addition, the images we use are either photographs we’ve taken, images in the public domain (thank you, NASA), or photos we’ve been granted permission to use. We conducted and filmed our video interviews. On a couple of occasions, mostly in the spirit of fun, we have re-posted videos from YouTube as WordPress.com allows.

We’ll be back. For now, we go black.

On March 2, Anna will be joined by four other writers at “Fallout & Facts: Creative Nonfiction in the Nuclear Age” at the Association of Writers and Writing Programs Conference. Panelist Kristen Iversen, author of the forthcoming Full Body Burden, has already contributed a guest post to Lofty Ambitions (click HERE). Today, we a post by another panelist, Jeff Porter.
We’ve not yet met Jeff Porter, though Anna read Oppenheimer Is Watching Me, one of the books that inspired the panel. The book draws from Porter’s past: his father worked for a defense contractor, and young Jeff, like many of us, was born into the Cold War. His essays have appeared in numerous literary journals, including The Antioch Review, Shenandoah, The Missouri Review, and Isotope (a journal of literary writing about nature and science that we are sad to say is no longer publishing). Jeff Porter teaches at the University of Iowa and focuses on media studies as well as creative nonfiction.
ON JOHN HERSEY, ATOMIC WRITER
Jeff Porter
I’m an atomic writer, though I wish I had a t-shirt to prove it. Any real evidence of what I am is kept secret in my mitochondria, and I’d rather not go there. A t-shirt would be much cooler.
The very first atomic writer, John Hersey, did not receive a t-shirt either. He did, however, get a personal issue of The New Yorker, the only time the entire magazine was turned over to one story. William Shawn had sent Hersey to Japan nine months after the bombing of Hiroshima, suggesting that he look into the lives of the survivors. In the countless words thus far printed about the bomb, rarely had the human side of the story been put before readers. That changed with the August 31, 1946, edition of The New Yorker. For 15¢, you could read the stunning documentary tale of six people who lived through the nightmare of Hiroshima.
In all, Hersey had met with over fifty Japanese survivors. He narrowed that group down to six—a Jesuit priest, a clerk, a seamstress, a physician, a Methodist minister, and a surgeon—each of whom he interviewed for six weeks before returning to New York. A month later, Hersey turned in a 150-page manuscript. Initially, the editors planned to run the piece in four consecutive installments of the magazine, as they would later do with Truman Capote’s In Cold Blood, but at the last moment Shawn decided to take the unprecedented step of devoting an entire issue to Hersey’s story.
The magazine’s editor in chief, Harold Ross, wasn’t sold on the idea of turning the genteel The New Yorker into a house of tragedy. Banishing the magazine’s signature cartoons in favor of gloom and doom seemed a bad idea. Nevertheless he signed on, but not before requesting hundreds of changes to the text. At 31,000 words, Hersey’s story took up all 68 pages of magazine space. Everything else was stripped away except for the cover art, which featured a lively park scene teeming with people at play that gave little indication as to what lay inside the magazine. For readers, this would be no picnic.
Here’s Mr. Tanimoto, the Methodist minister educated in the U.S., fleeing in confusion after the flash of the bomb:
Mr. Tanimoto, fearful for his family and church, at first ran toward them by the shortest route, along Koi Highway. He was the only person making his way into the city ; he met hundreds and hundreds who were fleeing, and every one of them seemed to be hurt in some way. The eyebrows of some were burned off and skin hung from their faces and hands. Others, because of pain, held their arms up as if carrying something in both hands. Some were vomiting as they walked. Many were naked or in shreds of clothing.
Though grim, a description like this is a far cry from later narratives of atomic disaster, such as The Day After (1983), television’s sensationalized account of American survivors of an imaginary nuclear war. In fact, Hersey’s text repeatedly understates the catastrophe, focusing instead on mundane details delivered in a deadpan voice. Hersey’s style is so flat as to be ironic, but the irony mostly serves to dignify the subjects of the piece at the expense of the spectacle.
By many accounts “the most famous magazine article every published,” Hersey’s story of Hiroshima found a way around the nuclear sublime (and the enchantment of a new technology) that would cast a spell over American writers for decades to come. He opened the door of atomic discourse to literature, and for that he deserved his very own magazine.
In the Footsteps (Part 11) January 11, 2012

We spent yesterday in Pasadena—at CalTech and Vroman’s Bookstore—because that’s how we chose to spend one of Doug’s vacation days. We had been planning to visit the CalTech archives for a while, but we chose yesterday because our colleague Tom Zoellner was reading at Vroman’s from his new book A Safeway in Arizona: What the Gabrielle Giffords Shooting Tells Us about the Grand Canyon State and Life in America. (His op-ed appears in today’s L.A. Times HERE, and we hope to have a guest post from Tom in the weeks to come.)
Tom’s reading was great, and he answered a lot of questions from the audience, creating a real discussion. Lest you think Tom Zoellner has nothing to do with our “In the Footsteps” series, his last book is Uranium, a well-written investigation of this radioactive element and our relationship with it over time. Zoellner recounts some of what we’ve covered in this series—the train station in Lamy, New Mexico, and Dorothy McKibben in Santa Fe—when he writes of the Manhattan Project, “An office on the plaza in Santa Fe was a discreet welcome center for the professors who stepped off the Super Chief streamliner, blinking in the bright sunshine at the foot of the Sangre de Christo Mountains.”
Before the reading, we spent the afternoon in the archives located in the subbasement of the Beckman Institute at CalTech. It’s a small operation with a few staff and one main research room. We had requested to see the papers of Richard Chase Tolman and Robert F. Bacher. Loma Kilkins wheeled out a cart of familiar storage boxes, and we started with the Tolman papers because there were just two. In fact, we didn’t get through all six boxes of the Bacher papers and will have to return for more research. After all, 39 linear feet (more than six times that of Tolman’s collection) of Nobel Prize recipient Richard Feyman’s papers still await.
Richard C. Tolman and Albert Einstein
What we like about archival research is that we never know exactly what we are going to find. A lot of the materials in these two collections were official documents, but even those reveal the signatures of President Franklin D. Roosevelt and President Harry S. Truman. In these collections, it’s also possible to start tracing connections to people with whom the public might be more familiar, such as Hans Bethe, Niels Bohr, Richard Feyman, or Linus Pauling. (All these men were Nobel Laureates, in fact, with Pauling awarded two prizes. CalTech alums, including our university’s economics professor Vernon Smith, have been awarded 17 Nobel Prizes, and CalTech’s non-alum faculty have been warded 14.)
Tolman, a physicist, was General Leslie Groves’s scientific advisor during the Manhattan Project. He had been a fellow in the American Academy of Arts and Sciences, an independent policy research center still working on the world’s complex problems. Some of Tolman’s papers reside in the CalTech archives because he joined the faculty there in 1922. Linus Pauling, who studied at Oregon State University (where Doug earned his PhD), shows up in the Tolman papers because he came to CalTech in 1927 and later declined an invitation to join the Manhattan Project.
J. Robert Oppenheimer and General Leslie Groves at Trinity Test Site
There are also wonderfully personalized parts of letters that are otherwise largely about scientific notions or career moves: hello to a wife, a mention of a recent visit. Tolman seems to have sent his talk and article “A Survey of the Sciences” to almost everyone he knew, and many of them responded, all positively but often with a quibble over this or that statement. In the less formal comments, we can glean an individual voice, a relationship, and the idiom of the time.
And there are little surprises, mysteries, too. Who is Helen Evereth? And why did Richard Tolman send her flowers on several occasions? She mentions her advancing age, along with expressing socialist political stances. Was she a great aunt or a former teacher or, perhaps, a sweetheart before he met his wife? Is she the Helen Evereth that the U.S. Census lists as having been born in 1874 in Maine? Helen’s are the most personal correspondence in the folders, but it’s impossible to piece together from these documents the story of Helen Evereth and Richard Tolman.
Perhaps our favorite piece of paper was a response to Albert Einstein (another Nobel laureate), instigated but not written by Tolman. The translation reveals that Einstein had submitted an idea to solve a problem with flight dynamics. The response, to put it simply, tells Einstein that they’d already thought of his idea and it doesn’t work. It’s heartening somehow to see plainly that even Einstein came up with notions that didn’t pan out and that even he faced rejection.
When you read a book like Uranium, you get what feels like the whole story. The narrative is figured out, and you find pleasure in its arc and cohesiveness. When you thumb through archives, you get tidbits, some of which state the obvious and expected and some of which don’t seem to fit. You find bits and pieces that could fit together in any one of a variety of ways but that also stand on their own for what they are (and were).

Before we get to today’s video interview, Lofty Ambitions extends condolences to the family and friends of Roger Boisjoly, who died last Friday. Boisjoly was a whistleblower in the Challenger accident investigation and an advocate for ethics in the workplace. You can read his guest post for Lofty Ambitions HERE.
Henry W. Hartsfield, Jr. (NASA)
Henry W. Hartsfield, Jr., became a NASA astronaut in 1969. But even before that, he was part of the U.S. Air Force’s MOL (Manned Orbiting Laboratory) program. Once part of NASA, he served in support roles for Apollo 16 and Skylab, as well as back-up pilot for STS-2 and STS-3 on the space shuttle.
Eventually, Hank Hartsfield got to space, first as pilot on STS-4 in 1982. He flew on two other space shuttle missions, STS-41D as commander and STS-61A. His crew for STS-41D on Discovery‘s maiden voyage included Mike Coats (see our interview with him HERE), Charles Walker (the first-ever payload specialist whom we mention HERE), and Judy Resnick (who later perished in the Challenger accident) as well as Steve Hawley and Mike Mullane. They launched three satellites and conducted science experiments. His last shuttle mission was the first with eight crew and was dedicated to the German contribution to Spacelab.
We interviewed the soft-spoken and earnest Hartsfield at Kennedy Space Center in 2010. Watch part of our fascinating conversation here.
International Geophysical Year and the Cold War (Part 2) January 4, 2012
Posted by Lofty Ambitions in Science, Space Exploration.add a comment
You may want to start with Part 1 of our piece about the International Geophysical Year (IGY) and the Cold War. To do that, click HERE.
In last week’s post, we gave an overview of the International Geophysical Year (IGY), a globally organized and implement scientific program, which took place from July 1, 1957, to December 31, 1958. As we have learned more about the IGY, it’s become obvious that, despite the stated goals of looking at the Earth, the Moon, and the Sun with the best available scientific minds and tools, IGY’s research program was not unrelated to the increasing of Cold War tensions between the United States and the Soviet Union.
Vanguard
As early as 1955, the United States made public its intentions to launch an orbiting satellite as a part of the IGY. President Dwight D. Eisenhower unveiled Project Vanguard to the world in July of that year. Shortly afterward, the Soviet Union announced they too would launch a satellite. Although the design and development of Project Vanguard was overseen by the Naval Research Laboratory, it was crafted as a tool of civilian science. President Eisenhower was particularly uncomfortable with the notion of military hardware orbiting (or flying) over the heads of the Russian people. (This same fear led to the development of the U-2 spy plane by the CIA, a “civilian” agency). In the end, the Soviet Union managed to reach Earth orbit first, in October 1957 with the successful launching of Sputnik.
Quaintly called “new moons” and “artificial planets” in the era of the first launches, the terminology almost leads one to believe that scientists of the time believed that they would need a only few to meet the science needs these satellites could serve. (That assumption strikes us as reminiscent of the 1943 quote from Thomas Watson, chairman of IBM: “I think there is a world market for maybe five computers.”) Instead, satellites have proven to be manifestly useful, with nearly 7,000 launched since October 4, 1957.
Explorer I, first United States satellite, was launched by ABMA on 31 January 1958. (NASA)
The Soviet Union launched three Sputnik satellites during the IGY, but very little IGY data was collected explicitly by the satellites themselves. However, lots of useful information about the mass and shape of the Earth was inferred from the orbits of the satellites. Both the United States and the Soviet Union lobbied international scientific bodies for the continuation of the IGY for another year. This resulted in the Year of International Geophysical Cooperation in 1959, which was the year that the Soviet Union launched its second series of satellites, the Luniks. As we follow the current GRAIL mission (see recent posts HERE and HERE on that), Luniks were intended to observed the Moon. In fact, the October 1959 mission of Lunik III captured the first images of the dark side of the Moon.
Principals at White House press conference, 28 July 1955, announcing United States participation in the IGY satellite program. (NASA)
Having watched the Soviet Union successfully launch the first satellite with the use of military (yes, military, not civilian) hardware, the R-7 ICBM, the Eisenhower administration backtracked to reignite the previously cancelled Explorer Program, which used the Army’s Redstone surface-to-surface missile, restarted. Less than three months after the program was restarted, it launched the Explorer I satellite on February 1, 1958. That success couldn’t have come at a better time, as the Soviet Union had already launched two Sputniks by this point, and Project Vanguard had suffered a dramatic failure—an explosion—on national television in December 1957. If one of the pleasures of old age is having the last laugh, Vanguard I has clearly won in this respect. It is still orbiting the earth long after the fiery demise of the Sputniks and the Explorers. In fact, with its present orbital decay, Vanguard I should continue to circle the globe for almost two hundred more years.
The Explorer series of satellites did produce one of, if not the most, dramatic discovery of the IGY program: the Van Allen radiation belts. (We mentioned Iowan Dr. James Van Allen in last Wednesday’s post; see the link at the start of this post for that.) As Van Allen and his team analyzed the data from Explorer I, they noticed that radiation counts were varying with the satellite’s height. Data collected by Explorer III (launched March 26, 1958) confirmed that our planet is encircled by two distinct bands of charged particles.

Not all of the IGY/Cold War drama was played out in outer space. One particularly noteworthy event took place in the ocean, in Santa’s backyard under the ice of the North Pole. During the summer of 1958, the USS Nautilus, the world’s first nuclear powered submarine, took part in Operation Sunshine, a mission to navigate to the North Pole underneath the Arctic Ocean ice. Nautilus reached 90 North on August 3, 1958. Her contribution to the IGY program was the first continuous bathymetric survey (depth measurement) of the Arctic Ocean. The USS Skate, the third nuclear submarine, also participated in the mission, reaching the North Pole on August 11th and surfacing through the ice.

Interest in the IGY transcended the political and scientific realm and made its way into the public consciousness. The Swiss watch company Jaeger-LeCoultre produced a special model—the Geophysic—to celebrate the IGY. In an unusual event that ties this week’s post into a neat little bow, Jaeger-LeCoultre presented the captains of the USS Nautilus, Commander William R. Anderson, and the USS Skate, Commander James F. Calvert, each with a Geophysic. What made the gift slightly unusual were the presentation cases, replicas of Sputnik. One wonders how the Navy officers felt about the reminder that the Soviet Union beat the United States to launching the world’s first manmade satellite.
Guest Blog: Brigid Leahy January 2, 2012

We know this week’s guest blogger exceptionally well. Brigid Leahy is Anna’s sister and a fellow alum of Knox College, where Doug met her lo those many years ago. By day, Brigid is Director of Legislation at Planned Parenthood of Illinois, but when she’s not at work, she’s an Elvis fan and fosters dogs for the Animal Protective League. Honestly, we thought, if Brigid wrote a guest post for us, it would be about airsicknesses, a topic about which she knows a great deal. But she found an even better, and more timely, topic as this week’s Lofty guest blogger.
This coming Sunday, January 8, marks Elvis Presley’s 77th birthday. We’ve written about music before at Lofty Ambitions (click HERE for a post on shuttle wake-up songs), but it’s not always easy to find the connection between music and the focuses of our blog. Brigid, however, found a great way to honor The King and write about aviation.
ELVIS PRESLEY, AIRPLANES, & ME
I have been an Elvis fan since I can remember. I love his music and his movies. I would rush home after school for our local Channel 3’s “Elvis Week,” which would air a different Elvis movie each day. I’ve seen Clambake nine times. For years I had been waiting to go to Graceland at a time when I could go by myself and spend as much time there as I wanted. This past summer, I was finally able to go to Graceland. I booked the full tour—the house, the special clothing exhibition, the automobile museum, AND the airplanes!
On January 8, 1935, Elvis Aaron Presley was born to Vernon Elvis and Gladys Presley in a two-room shotgun house built by his father in Tupelo, Mississippi. His father worked odd jobs and money was tight. In 1938, they lost their home. Thus, Elvis spent much of his childhood living in public housing or with relatives. His family was often dependent on government food assistance. In Tupelo, schoolmates teased Elvis for being a “trashy” kid who played hillbilly music and lived on the wrong side of town in a largely African-American neighborhood. Life after moving to Memphis was much the same, with the family living for a year in rooming houses until they were granted a two-bedroom apartment in a public housing complex. Elvis continued to be teased and was labeled a shy, mama’s boy.
We are often surprised, of course, by who grows up to do what. Elvis’ music career allowed him to reject his difficult childhood in many ways and to remake himself. During his junior year in high school, Elvis became more and more willing to perform for an audience. He began to dress with more flash, taking his fashion cues from the performers on Beale Street. His daughter Lisa Marie would later say that Elvis never owned a pair of blue jeans once he became a star because jeans were a staple of his poor childhood. Each day he would not emerge from the second floor of Graceland until he was fully dressed and accessorized with expensive jewelry. Elvis quickly became known for the opulence of his dress, jewelry, home, and transportation.
Elvis’s growing inclination toward extravagance is seen early in his career with his purchase of Graceland in 1957. The 18-room mansion reflects Elvis’s sense of luxury at the time. By today’s standards of “Lifestyles of the Rich and Famous,” however, the place may seem to some visitors small and rather tacky. But to the 22-year-old Elvis, Graceland was the fancy family home that he could provide for his mother. Once Elvis’s fame became so overwhelming that he could scarcely go anywhere without being recognized, this home became a refuge.
Elvis Presley's Convair 880
While Graceland was above the middle-class standards of the time, it wasn’t over the top. However, Elvis’s airplanes are definite signs of unrestrained opulence. Elvis leased and owned several aircraft (a Grumman Gulfstream G-1, a Fairchild F-27, an Aero Jet Commander, a Lockheed JetStar, a Dessault-Falcon), and it’s likely that the planes were purchased out of practicality because Elvis could not travel on commercial airlines. He was just too famous, and his schedule demanded a lot of travel. But these airplanes weren’t merely serviceable. They were remodeled lavishly to Elvis’s particular taste.
Gold-Plated Seat Buckle on the Lisa Marie
The most famous of Elvis’s aircraft is the Lisa Marie, which he called “The Pride of Elvis Presley Airways” and his “Flying Graceland.” On April 17, 1975, Elvis spent $250,000 on a Convair 880 Jet, which had been in service with Delta Airlines. (For another take on the Convair 880, check out an article HERE at Airliners.net.) The Convair 880 was in production for about three years, with 65 total aircraft manufactured. Elvis spent an additional $350,000 refurbishing it—that’s right, he spent more on redecorating and upgrading than on the initial purchase. He then christened it the “Lisa Marie” in honor of his daughter.
The Restroom, with gold-plated sink
Elvis personally oversaw the transformation of the Lisa Marie by selecting the color scheme, choosing fabrics, and flying several times to see the plane’s progress at Meacham Field in Fort Worth. After its refurbishment, it had seating to 28, but usually only about ten people were on board. All seating was equipped with gold-plate seat belt buckles. The plane was lavishly outfitted with a seating area, a conference room, and a private bedroom. The Lisa Marie had two restrooms, both with 24-karat gold plate washbasins and fixtures. The videotape system was linked to four televisions, and the stereo system had 52 speakers. The conference room was finished in teak. The bar was always stocked with 15 kinds of soda pop, though Elvis preferred Dr. Pepper and Lime Gatorade and didn’t really care for alcohol. It also had a “penthouse bedroom” with a custom-made queen-sized bed. Because of federal regulations, the bed was furnished with a seat belt. It, too, had a gold-plate buckle. The plane’s tail displayed Elvis’ TCB logo.
On November 27, 1975, the Lisa Marie made its first official flight, fittingly traveling to Las Vegas. Its tower call name was 880 Echo Pappa, and its nickname was Hound Dog One. Elwood David was the captain and pilot. Also on staff were another pilot, Ron Strauss, and a flight engineer, Jim Manny. The Lisa Marie was used for more than business travel. One Christmas, Elvis took his family and friends on a joyride. Another year, Lisa Marie blew out her birthday candles in the conference room while in mid-flight. After Elvis’ death, the plane was used to pick up Elvis’ ex-wife, Priscilla Presley, Lisa Marie, and the actor George Hamilton so that they could quickly come to Graceland. The operating cost for 1976 (the year before Elvis’s death) was $404,000, and it burned 1700 gallons of fuel an hour.
Vernon Presley sold the Lisa Marie in 1978. Its ownership changed hands a few times. Finally, in 1984, the Lisa Marie returned to Memphis and has been housed at Graceland as an exhibit ever since. The Lisa Marie is the only one of nine remaining Convair 880s that is properly preserved, and no Convair 880 remains airworthy.

GRAIL: Another Lofty Quest (Part 10), Next Stop: The Moon! December 31, 2011
Posted by Lofty Ambitions in Science, Space Exploration.Tags: GRAIL: Another Lofty Quest, GRAILTweetup
add a comment
In September, Doug spent five days on the Space Coast participating the NASA Tweetup for GRAIL, the Gravity Recovery And Interior Laboratory. We covered this launch extensively (HERE is the link for all GRAIL-tagged posts, or click on the GRAIL title in the tag cloud in the sidebar).
Suffice it to say, as with attending most rocket launches, schedules don’t really mean much. Launch windows are set, but if everything doesn’t line up in those seconds, there’s usually the next day. After two delays, the Delta-II rocket launched on Saturday, September 10. Doug was there to capture some amazing images (see the launch photos HERE).
Today, that mission enters a new phase. At 1:21 PST, the first of the GRAIL twins, GRAIL-A (the mission requires two mirror-twin satellites, A and B) begins a 40-minute lunar orbit insertion burn that will leave the 440 lb satellite in an elliptical orbit over the lunar surface. Think surfboard shaped, with your back foot as the Moon and the satellite tracing the shape of the board. The back of the board, or the lowest point in the orbit is known as perigee, and the front of the board, or highest point in the orbit is known as apogee. (We really have gone all SoCal.)
GRAIL on its way to the Moon
GRAIL-B will start its 39-minute lunar orbit insertion burn tomorrow at 2:05 PST. Over the next several weeks, each satellite will undergo twenty separate corrections to leave them in the circular orbit (34 miles high, or roughly the distance from Naperville to Chicago) necessary for the science phase, which begins in March. At that time, the spacecraft will map the Moon’s gravitational gradient. During the science phase, the separation between the two craft will vary from 62 to 140 miles.
Considering the investment, both in the number of decades and the dollars (and rubles, euros, yen, yuan, and rupees—Russia alone has sent twenty missions to the Moon), that we have made in understanding our planet’s lone natural satellite, we still have shocking gaps in our knowledge about our nearest neighbor in the heavens. Fundamental questions such as why the light and dark sides of the moon are so completely different (the dark isn’t just dark because sunlight doesn’t reach it, but is actually made of different materials than the light side) remain only partially answered at best. If all goes well for the GRAIL twins, in the very near future we will begin to address a host of questions regarding the Moon. GRAIL principal investigator Maria Zuber estimates that the science mission of GRAIL will increase our knowledge about the Moon’s light side by a hundred times and the dark side by a thousand times. (If you read our earlier post this week HERE, you know this means we will be increasing our knowledge about the light side by two orders of magnitude and the dark by three).
Doug’s trip to the GRAIL NASATweetup was just one of our four (yes, four!) separate trips to NASA’s Kennedy Space Center and the Space Coast in 2011. Reflecting on those trips reminds us what a remarkable year this was for us. It also points out the futility of attempting to predict the future. A year ago today, we certainly were kicking around the idea of heading back to the Space Coast to catch one of the final space shuttle launches, but we knew we’d miss the February launch of Discovery because of our work schedules so we weren’t sure what our opportunities might be. We knew we had to go back, and we remain grateful that Chapman University recognized what the subsequent trips might mean for us.
As we conclude 2011, we wish all our readers and followers a happy new year. Look up at the Moon tonight—you won’t be the only one peering at it—and imagine a great year opening before all of us.

As a group, scientists have a generally deserved reputation for being canny with numbers. Perhaps this perceived facility has also earned them a certain flexibility toward—what a lay person might perceive as casualness with—numbers. On occasion, early estimates of quantities or measurements are said to be correct within an order of magnitude, or a single power of ten. (Powers of ten are ably demonstrated in a film of the same name, which we discussed HERE.)
During the Manhattan Project, initial estimates of the amount of fissile material (in this case uranium) necessary for making an atomic bomb were said to be correct plus or minus an order of magnitude. As the story goes, this pronouncement led General Leslie Groves, military leader of the Manhattan Engineer District, to offer up the analogy of planning for a wedding with a hundred guests, except that perhaps as few as ten or as many as a thousand people might turn up.
Our post today stems from a time when a group of the world’s scientists got together and arranged for an 18-month year: the International Geophysical Year (IGY), which spanned July 1, 1957 to December 31, 1958. During the IGY, scientists from 67 nations collaborated on performing experiments and collecting data in eleven major scientific areas: “aurora and airglow, cosmic rays, geomagnetism, glaciology, gravity, ionospheric physics, longitude and latitude determination, meteorology, oceanography, rocketry, seismology, and solar activity.”
The IGY was a direct descendant of two previous International Polar Years, the first held in 1882-1883 and the second in 1932-1933. Years later, at a dinner party in honor of Oxford geophysicist Sydney Chapman held on an April 5, 1950 at the home of James Van Allen (later of the Van Allen radiation belts), the assembled handful of scientist-guests, several of whom had participated in the most recent International Polar Year decided that, instead of waiting the customary 50 years between International Polar Years, they would have one to correspond with an upcoming peak in solar activity (which is on an 11-year cycle). The name change from International Polar Year to International Geophysical Year was consciously chosen to reflect science’s growing ability to focus on problems that encompassed the entire earth.
James Van Allen with Soviet Scientists, 1959 (NASA)
April 5, 1950, (which was Doug’s father’s ninth birthday) must have been quite an eventful day in Dr. Van Allen’s personal life. In addition to hosting a dinner party that would lead to the largest international scientific endeavor to that point in history, he also accepted a Guggenheim fellowship to work at Brookhaven National Laboratory that day, ending nearly a decade of work at Applied Physic Laboratory at Johns Hopkins University.
The American IGY effort required a large number of participants coordinated by the U. S. National Committee (USNC), which was formed at the behest of the National Academy of Sciences. In a historical overview of the IGY, the NAS has this to say: “American participation in the IGY was charged to a US National Committee (USNC) appointed in March 1953 by the NAS. Joseph Kaplan, Professor of Physics at UCLA, was appointed Chairman of the USNC. Physicist Alan H. Shapley of the National Bureau of Standards (NBS) was appointed Vice-Chairman, and Hugh Odishaw, also of the NBS, was appointed Executive Secretary (later, Executive Director). The core USNC was made up of sixteen members, but the five Working Groups and thirteen Technical Panels that operated under it eventually drew in nearly 200 additional scientists.”
As ever, we at Lofty Ambitions respect an unanticipated connection, and we have one here with the appearance of the name Alan H. Shapley. This Shapley was the son of astronomer Harlow Shapley about whom we wrote HERE.
Fundamental science was performed during the IGY in areas such as seismology with the confirmation of plate tectonics as evinced by the discovery of a continuous mid-ocean ridge. We’ve touched upon plate tectonics recently (HERE) and in our series related to the tsunami that overwhelmed the Fukushima Daiichi nuclear power plant (HERE and HERE). Seismic and volcanic activity along parts of the mid-ocean ridge had been well documented prior to the IGY, but what wasn’t previously known—and was revealed as a part of IGY research—was that there was a more-or-less continuous ridge of nearly 50,000 miles in length, reaching into every ocean, encircling much of the earth. It is our planet’s largest extant mountain range.
GRAIL launch, September 2011
Probably the most significant scientific contributions of the IGY was the discovery of the Van Allen radiation belts (Van Allen of the IGY-initiating dinner party). Undoubtedly, we’ll soon have more to say about the Van Allen belts, how their discovery came about, and what the Cold War has to do with that. And we’ll have more about mapping, too, for the two GRAIL spacecraft are scheduled to reach the Moon this coming weekend. (To catch up on GRAIL, click HERE and HERE.)

On This Date: Radium, Tu-144, and Earthquakes December 26, 2011

On most Mondays, we post either a piece by a guest blogger (first and third Mondays) or a video interview (second and fourth Mondays). We do have video interviews queued up for the new year (and just wait ’til you see who!), but today we take the opportunity for one of our “on this date” posts.
Marie Curie (National Museum of American History)
In 1898, just three years into their marriage, one of our favorite collaborative couples of yesteryear announced at the French Academy of Sciences that they’d isolated radium. Marie and Pierre Curie had isolated the element five days earlier, though it wasn’t named until the following year. They did come up with the term radioactivity, and radium was the second ray-producing element they’d discovered that year. The first was polonium. They continued to work with an enormous amount of pitchblende to isolate a wee bit of radium. And they didn’t patent their processes, thereby allowing the larger scientific community to readily use their work.
Radium was applied as luminescence on watch dials and aircraft switches, which, it turned out, was quite dangerous for those who painted those dials and switches. It was also added to cosmetics before such a glow was considered hazardous. Later, it was used to treat cancer, though, of course, because it is radioactive and because the body processes it like calcium, it likely caused the leukemia and related illnesses from which Marie Curie died in 1934.
Marie Curie was awarded her second Nobel Prize in 1911, this time in chemistry, in part for her role in discovering radium. (Because Pierre died in 1906, he did not share in this award.) Her earlier Nobel Prize, which she shared with Pierre and Henri Becquerel in 1903, was in physics for their work in radiation. She was the first woman to be awarded a Nobel Prize, the first person to be awarded a second, and one of just two people to be awarded Nobel Prizes in different fields. (Linus Pauling is the other.) We’ve written about Marie Curie before—click HERE to read more.
Tu-144 (NASA)
Today is also the anniversary of the Tupolev Tu-144’s entry into supersonic transport service in the Soviet Union. The Soviet government began developing this aircraft in 1963. But the first production airliner crashed at the Paris Air Show in 1973. Accusations of espionage and cover-ups surrounded the investigation. With delays after this debacle, the Tu-144 ended up first flying mail on this date in 1975, with commercial flights beginning almost two years later (and almost as long after Concorde started its commercial routes). The Tu-144, which shares so many design cues with Concorde (dropped nose, cranked wing, and slender fuselage) that its nickname in the Western press was Concordski, was riddled with problems and had only a short commercial run, flying passengers from November 1, 1977 through June 1, 1978. A more recent use of the Tu-144 was as a flying laboratory for NASA.
Map of This Earthquake and Aftershocks (USGS)
This past year, one of the top news stories was the earthquake and tsunami in Japan and the subsequent damage to the nuclear power plant at Fukushima Daiichi. (Read some of that HERE and HERE.) Today is the seventh anniversary of another devastating earthquake, a 9.2 (numbers vary by source) quake in Indonesia, India Thailand, and the surrounding areas, that also produced tsunamis. It was so strong that some estimate that the entire world moved a full centimeter. As with most recent earthquakes, this one in the Indian Ocean was the result of subduction, or one tectonic plate scraping under an adjacent tectonic plate. In this case, hundreds of miles of a tectonic plate moved about 50 feet.
When this subduction occurred, the seabed rose, pushing water up. In the vast, deep ocean, that sort of wave isn’t much of a problem and is difficult to detect. But as the tsunami reaches shores, the wave can be devastating, and no warning system was in place for the Indian Ocean. The tsunami, of course, reached different shorelines at different times—several minutes or several hours—depending on the distance of the land from the earthquake’s epicenter. In some places, the waves washed a mile inland.
This natural disaster killed almost 230,000 people and is considered one of the ten deadliest natural disasters of all time. In addition to the cost of human life, it devasted coral reefs and wetlands and contaminated freshwater sources. Haiti’s earthquake, the second anniversary of which occurs next month, was even deadlier. Earthquakes change the face of the earth and the faces of the world.
