Flying Low and Slow Over a Lava Flow

This September, Larry Crumpler, a research colleague at the New Mexico Museum of Natural History and Science, and I were able to fly in the back seats of two weight-shifting ultralight aircraft during a two-hour flight over the McCartys lava flow in central New Mexico. This flow is 3,000 years old and over 47 km (29 miles) long, one of the longest fresh lava flows in the continental United States. It has been the subject of on-going research by Larry, other colleagues, and me as part of my research grant funded by NASA through the Planetary Geology and Geophysics program.

Larry made contact with the ultralight pilots through his museum in Albuquerque, and following some field work on the McCartys flow this past April, Larry and I were able to make the first ultralight flight over the lava flow. Pilots Jeff Gilkey and Paul Dressendorfer are very experienced ultralight pilots, both having flown hundreds of times over the many natural wonders that abound in New Mexico and neighboring states. The April flight convinced both Larry and I that ultralights could represent a wonderful platform from which to obtain low-altitude stereo photographs, which should show much more detail than could be obtained from either commercial aerial photographs or satellite images.

For the September flight, I attached a Canon Eos Rebel digital camera to a monopole, with a remote trigger taped to the pole, plus two separate safety lines that attached the pole to me in a way that still allowed for easy movement. As we flew over the lava flow, the camera was held out from the side of the two-person open cockpit, oriented to point straight down. I was able to collect over 1,800 vertical photographs, including ones taken while following several GPS-specified lines to provide aerial coverage of places that we have investigated extensively on the ground. Meanwhile, Larry took photos from the second ultralight (for safety reasons, the pilots prefer to fly in pairs), providing context information of the mapping ultralight.

A quick check of the vertical photos has confirmed the great scientific value contained within low-altitude, low-speed aerial photographs. The stereo photographs should provide many new insights about the McCartys lava flow during the coming months, and they will also be included in future proposals to support research of lava flows in the New Mexico area.

This Pie is out of this World

Mercury

Goethe Pie Tectonic Ghost Craters on Mercury

It’s said that “art imitates life,” but how about baked goods imitating geologic formations!  Strange as it might seem, the MESSENGER spacecraft that has been orbiting the planet Mercury since March, 2011 has discovered unusual groups of ridges and troughs that do just that – imitate a common baked-good, a pie.  Families of extensional troughs or graben revealed by MESSENGER are encircled by contractional wrinkle ridges arranged in circular rings.  This pattern of ridges and troughs resembles the raised edge and cracks in a pie crust. But the analogy with “pie crust” doesn’t stop there. These families of landforms are directly associated with “ghost” craters, impact craters that have been flooded and buried by lava flows. The rim of the buried impact crater concentrates the contractional forces that forms a ridge ring, revealing the outline of the buried crater. So, to complete the analogy the impact crater is the pie pan.  We think the troughs or graben form from cooling and contraction of unusually thick lava flow units, like the custard filling cools in a pumpkin pie. It is the eruption and rapid accumulation of very fluid lava flows into thick cooling units in combination with global contraction from cooling of the interior of the planet that may explain why these families of tectonic landforms in ghost craters on Mercury have not been seen elsewhere in the Solar System.

“A Company of Scholars”: A Brief History of the National Air and Space Museum’s Fellowship Program

The Museum is accepting applications for fellowships from November 1, 2012 – January 15, 2013.

Most people know the National Air and Space Museum as the premier location in the United States, and perhaps in the world, for the display of the artifacts of aerospace history. Not so well publicized is the fact that the Museum is also home to what former Smithsonian Secretary Dillon S. Ripley called “a company of scholars … a small university that awards no degrees.” Ripley’s comments refer to his strong belief that the Smithsonian should be a place where scholars from around the world conduct research and exchange ideas with each other and with Smithsonian researchers. The Smithsonian has indeed become such a place and so has the National Air and Space Museum, most particularly in regard to its funding of and support for outside researchers who come here under the auspices of the Museum’s fellowship program.

Guggenheim Pre- and Post-doctoral Fellowships

In the mid-1960s, the Daniel and Florence Guggenheim Foundation pledged $250,000 (roughly equivalent to $1.7 million in today’s currency) to support three projects: an exhibition about the Guggenheim family’s longstanding support of aeronautical research and education; a public lecture series that featured prominent figures in aerospace history; and a fellowship that would allow graduate students to do historical research at the Museum.

red phoenix rising

Red Phoenix Rising: The Soviet Air Force in World War II, by Von Hardesty and Ilya Grinberg, University Press of Kansas.

Over the years, the Guggenheim Fellowship has sponsored such distinguished aerospace historians as Richard P. Hallion, among others. Hallion’s book, Legacy of Flight: The Guggenheim Contribution to American Aviation (Seattle: U of Washington P, 1977), was the product of an appointed Guggenheim grant at the Museum. Another early former Guggenheim Fellow, Joseph Corn, wrote his groundbreaking The Winged Gospel: America’s Romance with Aviation (New York: Oxford UP, 1983), the first true cultural history of aviation, at the Museum. Von Hardesty, a Guggenheim Fellow here (1978-79) began work on his pioneering work Red Phoenix: The Rise of Soviet Air Power, 1941-1945 (Washington, D.C.: Smithsonian Institution Press, 1982). This work was later revised as Red Phoenix Rising: The Soviet Air Force in World War II, Modern War Studies (Lawrence: University Press of Kansas, 2012). Hardesty later became a curator in the Aeronautics Department, with responsibility for Russian and Soviet aircraft.

In later years the Guggenheim fellowship was awarded competitively, and is now available to pre-doctoral graduate students and to Ph.D.s who are within seven years of having been awarded their degree. Jenifer Leigh Van Vleck, a recent Guggenheim Predoctoral Fellow (2006-2007) from Yale University, wrote her doctoral dissertation, “No Distant Places: Aviation and the Global American Century,” which is soon to be published by Harvard University Press. Van Vleck is an Assistant Professor, Department of History, Yale University. Phil Tiemeyer, a recent Guggenheim Postdoctoral Fellow (2009-10) from Philadelphia University worked on the manuscript for his Plane Queer: Labor, Sexuality and AIDS in the History of Male Flight Attendants, which will be published by University of California Press in February 2013.

 

Charles A. Lindbergh Chair in Aerospace History

Airlines of the Jet Age

Airlines of the Jet Age, A History, by R.E.G. Davies, Smithsonian Institution Press with Rowman & Littlefield, 2011.

Our most distinguished fellowship is the Charles A. Lindbergh Chair in Aerospace History. Originally, this award was an appointment made by the Museum’s Director, but is now competitive and open to senior scholars with a distinguished record of publication who are or are soon to be at work on books in aerospace history. The first holder of the Lindbergh Chair was Charles Harvard Gibbs-Smith, a pioneer in the history of early flight. A subsequent recipient was the late Ron Davies, who held the chair from 1981 to 1983, who then become our curator of air transportation, a post he held just up to the time of his death in 2011. His last book, Airlines of the Jet Age: A History (Washington, D.C.: Smithsonian Institution Scholarly Press, 2011), was published just before his death. The Lindbergh Chair for 2012-13 will be Stuart Leslie, author of The Cold War and American Science: The Military-Industrial-Academic Complex at MIT and Stanford (New York: Columbia UP, 1993). Dr. Leslie will examine six “iconic” architectural spaces that he believes transformed perceptions of the space age.

Ramsey Fellowship in Naval Aviation History

Wings and Warriors

Wings and Warriors: My Life as a Naval Aviator, by Donald D. Engen, Smithsonian Institution Press, 1997.

The Ramsey Fellowship was the result of a bequest by Juanita Ramsey, the widow of Admiral Dewitt Clinton Ramsey, who had commanded the carrier USS Saratoga during World War II, and who later became commander-in-chief of the Pacific Fleet before he retired. Paul E. Garber, whose pioneering efforts helped to found the National Air and Space Museum, was the first holder of the Ramsey Fellowship, which was an appointed position. Another appointed Ramsey Fellow was E. T. Wooldridge, who held the position from 1990 to 1994 and who was a curator in the Aeronautics Department and subsequently Chair, and later Assistant Director for Museum Operations. A later appointed holder of the Ramsey Fellowship was Donald D. Engen, a career naval aviator and officer, and former head of the National Transportation Safety Board, who became the Director of the Museum in 1996. Engen wrote his memoir Wings and Warriors: My Life as a Naval Aviator (Washington, D.C.: Smithsonian Institution Press, 1997), while a Ramsey Fellow. During Engen’s time as Director, the Ramsey Fellowship became a competitive grant.

Other Ramsey Fellowship holders were: retired U.S. Navy Admiral Gerald E. Miller, who wrote Nuclear Weapons and Aircraft Carriers: How the Bomb Saved Naval Aviation (Washington, D.C.: Smithsonian Institution Scholarly Press, 2001) during his tenure; Norman Polmar, who wrote Aircraft Carriers: A History of Carrier Aviation and Its Influence on World Events, Vol. I: 1909-1945 (Washington, D.C.: Potomac Books, 2006) during his tenure, and Thomas Wildenberg, who wrote All the Factors of Victory: Adm. Joseph Mason Reeves and the Origins of Carrier Air Power (Washington, D.C.: Potomac Books, 2005) during his tenure.

The National Air and Space Museum is no  longer accepting applications for the Ramsey Fellowship. The funds have been reprogrammed with the intention of providing funding for an eventual curatorial chair in naval aviation history.

A.Verville Fellowship

The A. Verville Fellowship was named for Alfred V. Verville, an innovative pioneer aviator and aircraft designer and manufacturer. The Verville Fellowship is a competitive grant that is open to academics and non-academics alike, who are interested in analyzing major trends, developments, and accomplishments in aerospace history.

Among the recipients are Dik A. Daso, former curator of military aircraft at the Museum, who worked on Hap Arnold and the Evolution of American Air Power (Washington, D.C.: Smithsonian Institution Press, 2001); Asif A. Siddiqi, who wrote The Red Rockets’ Glare: Spaceflight and the Soviet Imagination (New York: Cambridge UP, 2010), and Christine R. Yano, author of Airborne Dreams: “Nisei” Stewardesses and Pan American Airways (Durham, N.C.: Duke University Press, 2011).

Center for Earth and Planetary Studies Postdoctoral Program

The Center for Earth and Planetary Studies (CEPS) is the scientific research unit at the Museum. Most of the research in CEPS focuses on geologic processes that have shaped the surfaces of rocky bodies in the solar system, including the Earth.

CEPS has supported 22 post-doctoral researchers since the program began in 1994, drawing well-qualified candidates from a variety of U.S. and international universities. External grants, mostly from NASA, fund most of the salary, conference travel, field work, and other expenses. One fellowship is supported by a Smithsonian endowment. CEPS post-docs are able to submit research proposals for external funding as Principal Investigator, and many have funded a substantial portion of their own time, as well as subsequent careers in research.

To date, CEPS post-docs have published 46 peer-reviewed journal articles and chapters as lead author, and pre-doctoral research assistants have authored another 25. Post-docs have received 30 research grants totaling over $2 million. Two have served as participating scientists on three NASA planetary missions (Lunar Reconnaissance Orbiter, Mars Reconnaissance Orbiter, and the Dawn mission to Vesta), and others have supported missions by working with a CEPS staff scientist on a mission team.

Five of the 22 CEPS post-docs since 1994 are currently in residence. Of the 17 who have completed their appointments, seven are now university professors, six work for a non-profit research institute or university on grant-funded science projects, three have pursued careers in government, and one is in private industry.

The Aviation Space Writers Foundation Award

Right Stuff, Wrong Sex

Right Stuff, Wrong Sex: America’s First Women in Space Program, by Margaret A. Weitekamp, Johns Hopkins University Press, 2004.

In April 2000, the Smithsonian Institution and the National Air and Space Museum accepted a financial gift from Aviation Space Writers Foundation. In exchange for the gift, the Museum would “support financially the work of a journalist, writer, or not-for-profit organization that is engaged in research and writing on significant aviation and space issues, developments or achievements, the publication of which may increase or enhance public awareness and knowledge of aviation, space flight, or the aerospace industry.” The grant also includes archival projects and the “product created as the result of the grant award must be in any form suitable for potential public dissemination in print, electronic or broadcast or other visual medium, including but not limited to a book manuscript, a video or film script, or monograph.” The award is given every two years in even-numbered years (2012, 2014, etc.).

A past recipient of the award (in 2002) was Margaret Weitekamp for work on her book Right Stuff, Wrong Sex: The Science, Culture, and Politics of Lovelace’s Woman in Space Program, 1959-1963. In 2006  Matthew Morrison  received the award for a drama based on the life of Willie “Suicide” Jones, an African American professional parachute jumper and aerial stuntman. The current recipient (2012) is Rebecca Herman, a Ph.D. candidate at the University of California, Berkeley. Ms. Herman’s topic is the Pan American Airways World War II Airport Development Program, which will examine Pan Am’s development of airports in Latin America during World War II.

All in all, our Fellowship Program has significantly advanced the scholarship in aerospace history, technology and science.

Investigating the Apollo Valley

Mauna Kea

Patrick Russell investigating the geology of Apollo Valley on Mauna Kea, Hawaii

In July, I joined a team from Johnson Space Center and elsewhere in investigating the geology of Apollo Valley with rover-deployed scientific instruments. Apollo Valley is a former 1960s Apollo-era astronaut training site at 3,505 meters (11,500 feet) on Mauna Kea, Hawaii. The project was funded by NASA’s Moon and Mars Analog Mission Activities Program, which funds projects that simulate scientific, robotic, and human aspects of exploring the Moon and Mars, with the goal of designing the most effective, efficient, and well-integrated future missions.

With plentiful basalt lava flows and cinder cones in a dry, barren environment, Mauna Kea is a good analog for the Moon and Mars. Reworking of rocks by ice and water provides another analogy to likely Mars processes. I led the ground-penetrating radar (GPR) investigation, with the radar antenna mounted off the back of the rover. Other rover-mounted instruments included panorama and video cameras, a Moessbauer spectrometer, and navigation instrumentation.

By sending radar waves into the subsurface and detecting their reflections off objects and layers and different materials, GPR provides a view of the upper 3-6 meters (10-20 feet) of the subsurface. We were able to trace surrounding lava flows under the bouldery valley fill to some extent, from which we can estimate the volume of material filling the valley. Also evident were multiple layers of cinders, sands, and gravels that sometimes interfingered or truncated against each other, suggesting multiple episodes of material movement (by wind, water, or mass wasting) and different source directions.

Another important aspect of the project was the pre-field planning and post-field data analysis based solely on rover-collected data, by scientists who were not in the field, to determine how to improve planetary geologic exploration and science return from remote, robotic operations.

The rover itself (~272 kg. or 600 lbs. with four ~40 centimeter- or 16 inch-diameter wheels treaded with small metallic plates) was developed by a Canadian company, Ontario Drive and Gear, in coordination with the Canadian Space Agency, with a view towards future planetary surface missions. The rough lava surfaces, bouldery terrain, and slopes at the site provided grueling physical tests of particular interest to the rover’s engineering and design team. The rover turned in an impressive performance, proving to be quite capable on terrains far rougher than traversed by the rovers currently on Mars.

Was Mars Ever Habitable?

If all goes according to plan, on November 25th the Mars Science Laboratory (MSL) rover Curiosity will leave the Earth and begin its journey to Mars. Any delays due to weather or other factors should be accommodated by a launch window that extends until December 18th. The spacecraft will use a new landing system to arrive at its landing site on Mars in August, 2012, and the rover carries an impressive array of scientific instruments. The rover is about twice as large as the Mars Exploration Rovers Spirit and Opportunity, thereby enabling it to navigate terrain characterized by larger obstacles (such as rocks) as it travels up to about 200 meters (219 yards) per Martian day.

 

Curiosity

This artist concept features NASA's Mars Science Laboratory Curiosity rover, a mobile robot for investigating Mars' past or present ability to sustain microbial life.

The new landing system for the Mars Science Laboratory replaces the airbag system utilized by the Pathfinder and Mars Exploration Rovers during landing. The new landing system enables much larger rovers and science instrument payloads to be delivered to the surface of Mars than was previously possible and opens the door for future missions geared towards the eventual return of samples for the Red Planet. Upon entering the Martian atmosphere, the MSL spacecraft will first steer itself through the upper atmosphere before deploying a parachute and then using rockets and a tether to lower the Curiosity rover to the surface.

Curiosity’s mission is geared towards understanding whether Mars is or ever could have been habitable. Recent data from NASA’s orbiting spacecraft (Odyssey and the Mars Reconnaissance Orbiter) and the Mars Exploration Rovers suggests the planet has had a long and complicated history of changing environmental conditions and landscapes. Curiosity will follow those missions by deploying a diverse complement of instruments to interrogate the rocks and soils in the vicinity of the landing site. The “next generation” of instruments carried by Curiosity comprises a “mobile laboratory” and should lead to a quantum leap in our understanding of Mars’ potential habitability and how the surface of Mars evolved over time.

landing site

Images of Gale Crater, the selected landing site for the Mars Science Laboratory. The first image shows the regional context of Gale Crater (labeled on the left and discussed above) with colors representing the elevation of the land surface (purple lowest and red highest). The second image shows an example of high priority science targets for exploration near the ellipse (yellow box in first image shows the location) and the last image shows science targets within the target landing ellipse (white box in the first image shows the location).

Advances in landing precision enable consideration of smaller landing sites than was possible during prior missions and made it possible to access the selected landing site within Gale crater. Gale crater is attractive to scientists because there is a five kilometer (three mile)-thick section of layered rocks deemed likely to enable study of changing conditions on Mars over a time when the abundance and duration of water on the surface was decreasing over time. As water is an important factor in evaluating potential habitability, the chance to access the rocks that record the changes from relatively wetter to drier present an opportunity to learn a great deal about Mars as a planet and its potential as a possible abode for life.

Curiosity is an important step in the long term study of Mars and sets the stage for future missions that will be focused on whether there is or ever was life on Mars. By helping to understand whether the planet was habitable and, if so, for how long, MSL will help identify the likely environments and potential targets for future sample return and the eventual search for possible life.

The excitement should begin the day after Thanksgiving, so while resting after eating all that turkey, tune in to NASA TV and watch as Curiosity counts down towards lift-off and the start of an exciting new chapter in our understanding Mars and the solar system.

Visitors to our Museum in DC can also watch the launch, targeted for 10:25 am ET Nov 25, on the giant screen in the Moving Beyond Earth gallery.
