The STS-135 crew comes for a visit

The National Air and Space Museum was once again honored to host a space shuttle crew this past Friday. This visit was special because it was the STS-135 crew of the shuttle Atlantis, the historic final mission that returned on July 21. The crew was only four astronauts for this last flight, smaller than the normal seven.  Commander Christopher Ferguson explained that it was originally a contingency mission but in the end NASA decided that it was needed to deliver supplies to the International Space Station (ISS).

A surprising number of people in the audience had attended the launch and the energy in the room was palpable.  The audience included students visiting from Peru and a class from Bristol, England via videoconference.  Against a backdrop of a space shuttle model under a stunning projection of the limb of the Earth, the crew told about their trip and acknowledged its emotional impact. All were veterans of other missions and knew this may be their last trip to space.  Commander Ferguson admitted he found it difficult to leave to return to Earth and that the last night in space they all took time to reflect on their experiences as astronauts. They shared a group photo taken in space with a small U.S. flag that had been aboard STS-1, the first shuttle mission 30 years ago. They explained that they left the flag on the ISS in hopes that a future crew will return it to Earth and then take it again into space. [See video of the full presentation.]

Astronaut crews are great at answering the many questions that they receive from curious Museum visitors. This time the questions included:  What’s next for NASA? What’s a typical day like for an astronaut? Is the US going to the Moon again? Why go back to a capsule design? What is the food like in space? What does it feel like to return to Earth after being in space for several months? (Mission specialist Sandra Magnus answered that one because she lived on the ISS for four months). My favorite question was “does the shuttle get hot inside during re-entry?”  Pilot Douglas Hurley said astronauts don’t feel the inside cabin get warmer. They maneuver the shuttle to keep it cool before the descent to Earth and he said it feels like winter in the cabin. Most fascinating was his description of the pink and orange plasma that lit up the darkness around the shuttle on re-entry.  Because the landing happened at night, the light show was spectacular.

As they ended their presentation they showed the final photograph taken of a shuttle in space.  Of thousands of spectacular photos taken of shuttles in space over 30 years, perhaps this one is most poignant. It represents the end of an era.

Fortunately,  there is another chapter to the shuttle story. The shuttle fleet will be preserved and on display in museums around the country. The National Air and Space Museum looks forward to receiving Discovery next year.  If the shuttles could talk they would have many stories to tell.  It is left for historians to tell those stories and next year the Museum will complete installation of Moving Beyond Earth, a new exhibition devoted to the story of human spaceflight in the shuttle era and beyond.

And, of course, the Museum looks forward to hosting the next astronaut crew, whenever that will be.

Getting “Enterprise” Ready for Prime Time

Early on the morning of March 1, 2004, a small band of preservation specialists consisting of Anne McCombs, Steve Kautner, and Ed Mautner walked into the James S. McDonnell Space Hangar at the Steven F. Udvar-Hazy Center.  There was but a single artifact in that huge hangar — OV-101, Space Shuttle Test Vehicle, Enterprise.  The hangar was scheduled to open to the public on October 20, 2004. We had eight  months to clean the exterior and interior; repair and repaint damage to the faux tiles that covered the nose, belly, vertical stabilizer, and rudder; then strip and repaint the center fuselage and payload bay doors.  There we stood with buckets of water, gallon jugs of Amway LOC, which was recommended by NASA and their contractor United Space Alliance (USA), boxes of cotton rags, and a few ladders that would only elevate us 3-3.5 meters (10-12 feet) above the ground.  The size and scope of our task was truly daunting as Enterprise was 37 meters (122 feet) long with a wingspan of 24 meters (78 feet) and a vertical stabilizer that topped out at nearly 18 meters (60 feet) above the floor.

Space Shuttle Enterprise

The Space Shuttle "Enterprise" was the first spacecraft to be moved into the Steven F. Udvar-Hazy Center's James S. McDonnell Space Hangar in 2004.

Enterprise was originally planned to be an orbiter but was never fully outfitted for spaceflight.  In 1977, it served first as a test vehicle atop a modified 747 in a series of drop and glide tests from about 7,620 meters (25,000 feet).  When its primary test programs ended in 1979, it languished and its appearance began to deteriorate.  In 1983 it was refurbished with a fresh coat of paint and new markings for the 1983 Paris Air Show and the 1984 World’s Fair in New Orleans.  NASA transferred Enterprise to the National Air and Space Museum in 1985 where it was stored outdoors for two years and in a non-climate-controlled hangar for 17 years. During this time it became dirty and its paint continued to deteriorate.  After it came to the Museum, Enterprise continued to be a test bed for NASA. They performed launch vibration tests, facility test checks, arresting barrier, and emergency crew egress tests.  These last tests scarred the paint on the forward fuselage and payload bay doors.   Our job was to restore it to its  former pristine appearance.

 

Space Shuttle Enterprise

Space Shuttle "Enterprise" flew into Washington Dulles International Airport on November 16, 1985 atop a modified Boeing 747 carrier aircraft. Using cranes, the "Enterprise" was removed from the top of the 747 and lowered to the tarmac at Dulles on November 17. On December 6 the National Aeronautic and Space Administration transferred title of the "Enterprise" to the National Air and Space Museum at a black tie gala at the airport.

The ladders made the decision of where to start easy — hit the low hanging fruit — landing gear, wheel wells, and the belly.   As the month progressed we received high lift equipment which gave access to most of the top portions of Enterprise. We also received an additional member, Tony Carp, to clean and repair the vertical stabilizer and rudder. Tony also coordinated the removal of the OMS (Orbital Maneuvering System) pods, which were sent back to the Paul E. Garber Preservation, Restoration and Storage Facility for restoration.  Once finished with the exterior, we cleaned the cockpit, payload bay, and aft power plant bay.

Our next task was to scrape and sand off the deteriorated paint on the center fuselage and payload bay doors, an area measuring over 372 square meters (4,000 square feet). We did this from scaffolding erected on June 17th.  This structure enclosed and bridged Enterprise, allowing us to safely reach all of the upper areas. With the clock ticking, additional members were allocated on August 9th to do the final sanding, scraping, and paint prep, which we finished on September 2nd.

Our donated aerospace paint and primer arrived September 17.  Due to the space hangar’s filtration system and health and safety concerns we had to use rollers and apply the paint between 5:30 p.m. and 6:00 a.m.  PPG-DeSoto, the paint donor, provided an additive that “flowed” the rolled-on paint to give a smooth, sprayed-on appearance.  We finished the prep, priming, and white top coat in the wee hours of September 29.  The scaffolding came down the next day and we were left with just our original team of four plus two part-time volunteers to remove masking; do final clean-up and equipment stowage; touch up many of the polyurethane foam faux tiles; and restore the markings, “United States,” NASA “Worm” logo, and the name Enterprise on the forward payload bay doors.

Long before work began, several curatorial decisions were made. First, Enterprise did not need a full restoration.  It was structurally intact and had no signs of serious corrosion.  So it would be cleaned, signs of corrosion or deterioration noted, and deteriorated paint and markings would be replaced.  The second decision was to return it to its appearance in 1985. To achieve this we carefully traced all of the markings before paint removal began.  When we had sanded through the top layer of paint we discovered earlier markings similar to those of 1985, but with slightly different shape, location, and color shades.  We traced and made notes of these for future reference.  Once repainted, we retraced the markings in pencil then hand-painted them as had been done originally.  While doing this a contract crew was assembling the barriers around Enterprise in preparation for the “Grand Opening” just days away.  We finished clean-up and detailing on October 18, 2004.

While we never let our eyes slip from our target date, there were interesting diversions that made a challenging project pretty enjoyable.  We were tasked to assist NASA and USA in several of their planned visits to inspect or work on Enterprise.  One day, Col. Joe Engle, one of Enterprise’s command test pilots, came to visit his old craft, inquire about our work, and congratulate us on our efforts.  Another highlight was a visit from Col. Pamela Melroy, USAF.  Col. Melroy was an Air Force test pilot and would become a two-mission space shuttle pilot (STS-92 and 112), and mission commander (STS-120). We met her while she was still a member of the Shuttle Columbia accident investigation team. We escorted her through Enterprise and she also expressed pleasure with our efforts.

The Enterprise project was grand in scope; interesting and exciting every day; and very rewarding in terms of personal gratification.  Our small crew worked without a budget, and with limited resources, personnel, and time.  For so many reasons, I recall looking forward to getting in to work on it every day.  It was an exciting environment that literally put us on a stage where the visitors were always viewing us from barriers at the front of the hangar and from the hangar overlook.  And when the scaffolding was assembled, there was the ever-present element of danger.  Everyday, several times a day, we had to free climb 9-12 meters (30-40 feet) straight up the rungs to the platforms next to or over the shuttle.  Once on top, we could attach our safety harness tethers to the scaffold structure. In eight months we had only one injury.  One of our members slipped off the top of the payload bay doors.  Due to the harness and tether, he suffered only a banged knee.  Our constant discussions about safety and the use of fall protection certainly paid dividends.

During our days working on Enterprise we received several recurring questions about it from docents and visitors: is it real and did it go into space?  What does it look like inside and will the Museum let visitors walk through it?  Well, it is quite “real.”  It was the first shuttle of the first batch or “block” of three and with the demise of Challenger and Columbia, it is the sole survivor of that block.  Discovery, Atlantis, and Endeavour constitute the second block of shuttles.  However, as Enterprise was never fully fitted-out to be an orbiter, the payload bay is a maze of structure and framework that poses too many hazards to permit public entry.  The cockpit, bare of instrumentation, is very small and it would be difficult to route the more than one million visitors who might wish to enter it each year. Furthermore, the National Air and Space Museum has not in the past opened accessioned aircraft or spacecraft for public entry due to preservation concerns.  For all of these reasons the Museum decided not to permit access into Enterprise.

On the morning of October 19, 2004, members of the press began to arrive to photograph, video, and write about the opening of the John S. McDonnell Space Hangar and its most prominent artifact, the Space Shuttle Enterprise. The public got its first glimpse the following day.  The space hangar and Enterprise were received with praise and excitement by NASA and Museum staff, the media, and the visiting public.  In addition, our small team received one of the two prestigious Peer Awards presented by the Museum for 2004.  Was it a rewarding project? You bet.

Women’s Place in Space

As she became the first American woman in space in June 1983, headline-writers couldn’t resist wordplay on her name: O What a Ride! A Ride in Space, Sally’s Ride into History, Sally’s Joy Ride.  People at the launch chanted and wore T-shirts emblazoned with the slogan “Ride, Sally Ride,” echoing the refrain of the 1960s hit song “Mustang Sally.”

Sally Ride

Sally Ride was the first American woman in space.

Despite this frivolity, Sally Ride’s presence on Challenger for the seventh space shuttle mission truly was a ride into history, for it broke the sex barrier in U.S. human spaceflight. Granted, it occurred 20 years after Valentina Tereshkova soared into orbit for the Soviet Union and almost 20 years after Barbie became an astronaut. Yet after that milestone passed, the space shuttle and then the International Space Station became places where women could work and eventually take command, as routinely as in workplaces on Earth.

Ironically the first American woman to go into space had not aspired to be an astronaut since childhood, as others had.  She learned of NASA’s astronaut recruitment as she completed graduate school and instantly decided to apply for a career in spaceflight.

The priority of Sally Ride might have been otherwise; any of the six women accepted into the 1978 class of astronauts might have been cast as the first to fly.  Anna Fisher, Shannon Lucid, Judith Resnik, Sally Ride, Rhea Seddon, and Kathryn Sullivan completed training and qualified for flight assignments together. All flew in space within two years.

First Class of Female Astronauts

From left to right are Shannon W. Lucid, Margaret Rhea Seddon, Kathryn D. Sullivan, Judith A. Resnik, Anna L. Fisher, and Sally K. Ride. NASA selected all six women as their first female astronaut candidates in January 1978, allowing them to enroll in a training program that they completed in August 1979.

These six women navigated together through the ways of an all-male astronaut corps. In their wake a total of 48 women became astronauts, accounting for almost 20% of the 258 astronauts selected for the shuttle-space station era and including seven women of African-American, Hispanic, or East Indian descent.

Only three women were selected as pilots: Eileen Collins (USAF), Susan Still Kilrain (USN), and Pamela Melroy (USAF), all of whom arrived in the 1990s after gaining the requisite military flight experience. A woman commanded three of 132 shuttle missions launched to date. Collins flew twice as pilot and twice as commander; Kilrain flew twice as pilot; and Melroy flew twice as pilot and once as commander.  All have now left NASA so there will be no women seated up front on the final missions.

Forty-five women have served as mission specialists— the onboard scientists, engineers, and physicians responsible for much of the workload in orbit.  They hold 25 Ph.D. degrees in various fields of science and engineering and seven M.D. degrees. Three of them—Bonnie Dunbar, Shannon Lucid, Tamara Jernigan—have flown in space five times. One woman—Peggy Whitson—served as space station commander and set a new long-duration space record. More than half of the women astronauts also fly aircraft.

Sally Ride made history as the first U.S. woman in space, but the feat is more nuanced. She and the other five women who were first selected to be shuttle astronauts each made history, through grit and determination and some dreaming, to be ready for the opportunity of spaceflight. They entered science and engineering in the 1960s as these fields began to open up to women. They came of age as the civil rights, equal rights, and women’s movements stimulated changes in American society and opened new career possibilities. They were poised to step through the door opened by NASA’s affirmative action policy and its aggressive recruitment of women and minorities for the astronaut corps.

Accomplished American women have flown in space since 1983, so it no longer seems newsworthy; it’s just natural.  That is the history that flowed from Sally Ride’s shuttle mission.

Reflections on Post-Cold War Issues for International Space Cooperation

In the 1990s the United States collaborative space policy entered an extended period of transition from the earlier era of Cold War, one in which NASA has been compelled to deal with international partners on a much more even footing than ever before.

Apollo 17

Will the next flag on the Moon be a national flag or one representative of humankind as a whole? This image from Apollo 17 shows the U.S. flag on the Moon, an important symbolic moment for the United States in the Cold War race to the Moon with the Soviet Union. Those times have passed and cooperative efforts are the norm for the future.

This was true for several reasons. U.S. preeminence in space technology was rapidly declining, especially in launcher technology as other nations built their own internal capabilities. This was especially true of the European Space Agency’s superb Ariane launcher. This made it increasingly possible for other nations to “go it alone,” as a vernacular expression states.

U.S. commitment to sustained “preeminence” in space activities also waned and significantly less public monies went into NASA missions. The Clinton administration’s “National Space Policy” of September 29, 1996, for example, abandoned the language of preeminence that had been used since the origins of the space race in the 1950s. In addition, NASA’s budget declined in terms of real dollars every year from 1993 to 2000.

Of international cooperative projects that remained, NASA increasingly acceded to the demands of collaborators to develop critical systems and technologies. This overturned a longstanding policy of not allowing partners onto the critical technological path, something that had been flirted with but not accepted in the Space Shuttle development project.

This was in large measure a pragmatic decision on the part of American officials. Because of the increasing size and complexity of projects, according to former NASA international relations chief Kenneth Pedersen in 1992, more recent projects have produced “numerous critical paths whose upkeep costs alone will defeat U.S. efforts to control and supply them.”

Pedersen added, “It seems unrealistic today to believe that other nations possessing advanced technical capabilities and harboring their own economic competitiveness objectives will be amenable to funding and developing only ancillary systems.”

In addition to these important developments, the rise of competitive economic activities in space has mitigated the prospects for future collaborations. The brutal competition for launch business, the cutthroat nature of space applications, and the rich possibilities for space-based economic activities have created a climate in which international ventures may once again become the exception.

Historian John Krige astutely commented in 1998 that “collaboration has worked most smoothly when the science or technology concerned is not of direct strategic (used here to mean commercial or military) importance. As soon as a government feels that its national interests are directly involved in a field of R&D, it would prefer to go it alone.” He also noted that the success of cooperative projects may take as their central characteristic that they have “no practical application in at least the short to medium term.”

I would add that the sole exception to this perspective might be when nations decide that for prestige or diplomatic purposes it is appropriate to cooperate in space. A superb example of this is the effort beginning in 1992 to bring the Russians into the space station program already underway by a consortium of nations as a means of building stronger ties to Russia in the early post-Cold War era.

One of the key conclusions that we might reach about the course of international cooperation between the United States and its international collaborators in space is that it has been an enormously difficult process. I am reminded of the quote attributed to Wernher von Braun, “we can lick gravity, but sometimes the paperwork is overwhelming.” Even so, cooperative space endeavors have been richly rewarding and overwhelmingly useful, from all manner of scientific, technical, social, and political perspectives.

International Space Station Components

The International Space Station is the most significant international cooperative program in the history of spaceflight. This image shows the components of the station and which nation constructed them.

Kenneth Pedersen observed in 1983, “international space cooperation is not a charitable enterprise; countries cooperate because they judge it in their interest to do so.” For continued cooperative efforts in space to proceed into the twenty-first century it is imperative that those desiring them define appropriate projects and ensure that national leaders judge them as being of interest and worthy of pursuing them in a cooperative manner.

Shuttle-Era Shopping Spree

Being snowbound at home for a long weekend presented a perfect opportunity to go shopping online – for Space Shuttle artifacts!

A few days ago, NASA announced the second round of surplus property to be released from the Shuttle program when it ends later this year. Interested museums and educational institutions are eligible to browse a NASA-GSA website and request items for their collections and exhibits. The objects are free to a good home, but there will be shipping and handling charges. In the first round announced last fall, the Museum snagged several items on our wish list.

As Space Shuttle curator, I am coordinating the National Air and Space Museum’s collecting effort with several colleagues in the space history division primarily, though some items also draw the attention of colleagues in the aeronautics and archives divisions. Together we are seeking Shuttle-era artifacts that inform the intellectual basis of the national collection or match the long-established categories of objects within the collection. We are the Museum’s “personal shoppers.”

What is the intellectual foundation for the space history collection? As historians, we are engaged in an ongoing effort to understand the meaning of spaceflight in American history and culture, the technologies and institutions and people that make it possible, the successes and failures, and even the mundane routines of living and working in space. We seek material objects that enable us to document, display, and preserve our nation’s human spaceflight experience and to explore its significance in our research and exhibitions.

Already part of the National Collection: a Star Tracker that flew on 16 Space Shuttle missions, including Columbia's maiden voyage, and space food (scrambled eggs) that flew on STS-27. Just some examples of the types of Shuttle-era objects the Museum collects.

Our collections are organized in categories, rather like the biologists’ class-genus-species taxonomy.  We have broad programmatic categories (Mercury, Gemini, Apollo, Skylab, Shuttle, Space Station) and broad technical categories (crew equipment, rockets, spacecraft, etc.)  Specific artifacts are organized into such pigeonholes as avionics, clothing, computers, food, spacesuits, and tools.

So what was I shopping for online?  The conveniently alphabetized list of 653 object types started with Accelerometers and 13 long pages later ended with Wing Leading Edge batteries, with scores of sensors and transducers in between – the kind of stuff one might expect to see on a warehouse shelf but not in an exhibit.  But scrolling on, I spotted some real treasures, most of them flown in space:

  • a cycle-ergometer for crew exercise
  • an in-flight maintenance kit of 147 tools
  • some computers and camera equipment
  • parts of an extravehicular activity spacesuit (no complete suits are being released)
  • an Apollo 8 audio tape – wonder what that’s all about!
  • even a Shuttle emesis bag (to add to our impressive collection of airline barf bags)

Most of these items illuminate the realities of living and working in space.

I spent more time on this online “window shopping” than I’ve ever spent browsing in a shopping mall, but it was a very thoughtful exercise to look at each item and evaluate its significance. What is each object’s story? Is it worth preserving in the national collection? Why? How does it fit within, or stretch, our intellectual themes and artifact categories?

I will put these items in the Museum’s shopping cart and submit our request to NASA, along with a justification for each item. So far, we curators have selected and justified about 65 items after discussing their merits for the collection. Individually they may seem like a motley assortment, just as what you put in your grocery cart is a jumble. But each one has a place and a purpose in the Museum. Step by step, opportunity by opportunity, we are building a coherent collection of artifacts to document and preserve the history of human spaceflight in the Shuttle era.

The challenge of exhibiting "space"

P1010255

Watching the broadcast of the Space Shuttle Atlantis lifting off into the blue sky last week brought back memories of a research trip to the Kennedy Space Center last fall.  National Air and Space Museum staff members are hard at work on a new exhibition about the history of the space shuttle era and the International Space Station.  The trip included behind-the-scenes tours of various facilities at the Center and an up-close look at launch pad 39A with an elevator ride to 195 feet and a peek inside the entry hatch of Atlantis. What a thrill!

The challenge before the exhibition team is how to translate the enormity of the shuttle (positioned for flight, it’s taller than the Statue of Liberty) and the extreme conditions of space into a 5,000 square foot exhibition that is engaging, interactive and educational.  We can’t replicate the amazing Kennedy Space Center views or simulate a launch, but our partnership with NASA allows us access to fascinating artifacts and video footage.  In the end, our goal is to create an exhibition that capitalizes on the Smithsonian’s unique ability to provide museum visitors with a look at cool stuff, while learning an accurate story, and making personal connections to our nation’s history.  Phase I of the exhibition opens in October.
