If you missed last week’s post about Dryden Flight Research Center, you might want to start THERE. Otherwise, read on to continue the story.

A clear and consistent message was delivered at both the #DrydenSocial and last fall’s GRAIL Tweetup: NASA wants to use social media to help spread the word of its achievements. To that end, NASA trots out its best and brightest to address event attendees and then mixes in the kind of moments that only NASA can deliver.

David McBride, Dryden Center Director

To that end, the morning session of the May 4th NASA Social event at NASA’s Dryden Flight Research Center (DFRC) offered a broad overview of Dryden’s historical and continuing role in aeronautics research. David McBride, Center Director for DFRC and Christian Gelzer, Chief Historian, provided a wealth of contextual information in the day’s first two talks.

The wonderful Neil deGrasse Tyson, Director of the Hayden Planetarium and whose book, Space Chronicles: Facing the Ultimate Frontier, Anna has just finished reading, has been making some interesting comparisons regarding NASA’s budget of late. According to Tyson (watch the video HERE), the $850 billion spent on TARP, the Troubled Asset Relief Program, is greater than NASA’s budget for the fifty-plus years that NASA has been in existence.

In no particular order, here are some the achievements that NASA’s budget has funded in that five-decade span:

• the Hubble Space Telescope and its associated increase in our understanding of the universe;
• a significant portion of the International Space Station (ISS);
• the Space Transportation System (the shuttle) that carried Hubble and the ISS’s pieces into orbit;
• deep space probes such as the Voyagers, planetary landers and rovers such as Spirit, Opportunity, and Curiosity;
• myriad Earth-orbiting satellites that have taught us much about our planet’s weather, composition, and history;
• and of course, the Apollo program and the astronauts who landed on the moon.

Note that all of these scientific and engineering achievements have something to do with space. Space is sexy, space gets people’s attention.

LLRV (See, space looks sexy.)

That said, the first A in NASA is for Aeronautics. In recent years, aeronautics has been a remarkably small piece of NASA’s little pie. In his introduction to the NASA Social #DrydenSocial attendees, David McBride, Dryden’s Director, pointed out that aeronautics research receives about 2.5% of NASA’s roughly $18 billion dollar budget in any given year. Those monies go towards funding the four dedicated NASA Aeronautics Research Centers: Langley, Glenn, Ames, and Dryden. At the end of that quickly narrowing financial funnel, Dryden Flight Research Center (DFRC) receives less than 1% of NASA’s budget.

It turns out, however, that the first A in NASA is a really important part of the United States’ overall economic picture. McBride indicated that the manufacture of aircraft and its associated industries were the single greatest positive contributor to the U.S. balance of trade. NASA’s own web pages put the scope of aviation’s influence in the U.S. economy as follows:

“Aviation generates more than $400 billion in direct economic activity, supports more than 650,000 jobs and accommodates more than 600 million passengers every year in the United States.”

At last fall’s GRAIL Tweetup, Charlie Bolden also addressed the importance of aeronautics, when he said that he would like a part of his legacy as NASA Administrator to include leaving funding for aeronautics research on a “upward trend” in order to return NASA to its traditional status as the “premier aeronautics research organization in the world.”

SSBD at Valiant Air Command

The technical talks at #DrydenSocial started with engineer Ed Haering, who is a superstar in the world of supersonic booms. Haering’s presentation covered work that has been done at DFRC to mitigate—sshhh!—supersonic booms. Because commercial aircraft are prohibited from flying over land at supersonic speeds (this was a huge problem for Concorde), this research is imperative if we’re ever to see another supersonic transport aircraft. The Lofty duo actually had the opportunity to see some of Ed’s work up close and personal when we visited Valiant Air Command in Titusville, Florida. Valiant is the home of the Shaped Sonic Boom Demonstration (SSBD) aircraft, a test aircraft on which Haering worked at Dryden. As its name suggest, the SSBD successfully demonstrated that a sonic boom could be shaped to reduce its impact, and by impact, we mean noise.

SSBD

On the heels of Haering’s talk was an opportunity head outside and experience a sonic boom firsthand. Shortly after the #DrydenSocial attendees were led outside for a photograph beneath the wings of the X-1E, an F-18 flew overhead accompanied by the telltale crack of a sonic boom. Moments after that, the same F-18 treated us to a loud-and-low flyby.

NASA Dryden, or Anthony Nelson’s Office

In a day of artifacts and factoids, one that would have made a great impression on Anna, had she been there too, concerned the front of Dryden’s administration building. As we gathered around the X-1E, one of the handlers assigned to our group related that the front of the administration building had stood in for the NASA’s offices in I Dream of Jeannie. (If you want to read more about I Dream of Jeannie, click HERE.)

For Doug, though, the artifact that made the greatest impression was the insect-like Lunar Landing Research Vehicle (LLRV, in the photo above) which was located in a nearby hangar. The M2-F2 lifting body, used to validate the design of the space shuttles and located in the same storage space as the LLRV was a close second.

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.

Last Flight of the Concorde November 26, 2011

Supersonic passenger flight ended on November 26, 2003, the day a Concorde made its last flight, this time back to its birthplace in Bristol, England, where it was put on outdoor display. The Concorde’s last transatlantic flight had occurred roughly a month earlier (see video below).

The Concorde, a joint venture between the United Kingdom and France was riddled with problems right from the start, right down to whether the name should be spelled with (British) or without (French) the e on the end. Still, orders for more than 100 aircraft poured in, the industry was jazzed about this revolution, and construction of the aircraft began in 1965.

public domainThe drop nose and delta wing are among Concorde’s distinctive features, the former needed for pilots to see the runway and the latter developed to allow the plane to reach a speed of more than Mach 2 (about 1320 milies per hour). But supersonic flight at high altitude presented challenges for engine design, heating and cooling, braking, and cabin pressurization. And the price of fuel was rising. Only 20 aircraft were built, 14 of which were used for passenger service. The first scheduled flight occurred on January 26, 1976. But protests led Congress to ban Concorde landings. Even after the federal ban was lifted, New York City instituted a ban.

NASA public domainThe Supreme Court ended that prohibition, and flights from London and Paris to New York began on November 22, 1977. The record time between Heathrow and New York is 2 hours, 52 minutes. The public outrage subsided, as celebrities and the wealthy (Paul McCartney was a favorite of the crew) zipped back and forth across the Atlantic. The Concorde served more than one million bottles of champagne.

Doug toured the inside of the Concorde at the Museum of Flight in Seattle, where it sits outdoors. Anna saw the Concorde during its restoration at Scotland’s National Museum of Flight in the summer of 2004. Together, we’ve seen a Concorde sitting in the distance as we landed in Birmingham, England, and up close at the National Air and Space Museum’s Udvar-Hazy facility. The shape and size is pencil-like, as airplanes go, with the cabin ceiling just six feet from its floor and little room for carry-on baggage. When you look at this supersonic jet, you sense the speed it could achieve. But today marks the eight anniversary of its becoming an artifact.

Air France Flight 4590 July 25, 2010

Today is the tenth anniversary of the crash of Air France Flight 4590 just after take-off from Charles de Gaulle International Airport. The Concorde jet’s tire was ruptured by a small piece of titanium (Anna’s favorite metal) left on the runway after the previous plane took off. A chunk of the Concorde’s tire hit the wing, which led to a rupture in a fuel tank. The leaking fuel was ignited by electrical wiring. An article in the U.K.’s Guardian points to additional factors, such as weight, maintenance, and proximity to another aircraft carrying France’s president. One-hundred nine souls on board and five people on the ground perished on July 25, 2000.

In the wake of the accident, the supersonic jet was grounded. Almost a year later, flights were resumed, but the Concorde was retired on November 26, 2003, ending supersonic passenger service worldwide. In 1982, the price of a round-trip ticket was $3900, and by 2000, the price had more than doubled. United States astronauts outnumber Concorde pilots. It was a rare instance, this aircraft.

We’ll have more on the Concorde in future posts.
